Social Media Image Sizes


Profile Photo – 400 x 400 (Displays 200 x 200)

Your Twitter profile photo is the main image that represents you or your brand across the network. It’s going to be seen across the site in a number of places by a number of people so make sure it’s of the highest quality. Here are the places your profile photo will be visible on the site:

On Your Page
The largest display of your profile picture is on your homepage and can be viewed by your followers as well as individuals who stumble upon your page.

A smaller version of your profile picture appears in a follower’s Twitter stream every time you send out a tweet. It’s also going to appear in the stream of your followers’ followers every time that they retweet you.

Who to Follow
Your profile picture is also going to appear next to a link to your page in the “Who to follow” box. This is located directly to the right of your Twitter stream.

Image Guidelines
Square Image – recommended 400 x 400 pixels.
Maximum file size 100 KB.

Header Photo – 1,500 x 500

Your header photo is the image that spans the top of your Twitter profile page. It’s quite a bit larger than your profile photo so make sure to save it at the highest resolution possible.

Image Guidelines
Recommended 1,500 x 500 pixels.
Maximum file size of 10 MB.

In-Stream Photo – Minimum 440 x 220

Twitter gives users the ability to attach photos to any of their tweets. However, when you attach a photo to a tweet, Twitter needs to create a separate link for that photo, so ultimately you have fewer characters to work with. The photos that you upload are going to appear in the streams of your followers and the streams of their followers should your photo get retweeted. Photos that are included in public tweets may also appear in certain Twitter search results.

It’s also important to note that Twitter may collapse your photo into a smaller version to fit seamlessly into a user’s stream. In order to make sure that Twitter is displaying the portion of the photo you want followers to see, make sure the width of your image fits the minimum requirements and that your content is horizontally centered.

Image Guidelines
Minimum to appear expanded 440 x 220 pixels.
Maximum to appear expanded 1024 x 512 pixels.
Appears in stream collapsed at 506 x 253 pixels.
Maximum file size of 5 MB for photos and 3 MB for animated GIFs.


There is a difference between how things will display on your personal timeline and how things will display in a user’s newsfeed. Make sure that you are choosing dimensions based on where you want the majority of viewers to see your image.

Profile Picture – 180 x 180 (Displays 160 x 160)

This is the square photo that appears on your timeline layered over your cover photo. Your profile picture will also appear when you post to other walls or comment on posts.

Image Guidelines
Must be at least 180 x 180 pixels.
Photo will appear on the page as 160 x 160 pixels.
Photo thumbnail will appear throughout Facebook at 32 x 32 pixels.

Cover Photo – 851 x 315

Your cover photo will only appear in your Facebook timeline, but it is a lot bigger than the profile picture, which gives you more freedom to choose something creative. Where your profile picture might be a good choice for your logo, use this space to post something that highlights your organization or members.

Image Guidelines
Appear on page at 851 x 315 pixels. Anything less will be stretched.
Minimum size of 399 x 150 pixels.
For best results, upload an RGB JPG file less than 100 KB.
Images with a logo or text may be best as a PNG file.

Shared Image – 1,200 x 900

A shared image is one of the most common forms of sharing on Facebook. These images will always appear on your timeline, and ideally they will show up in most of your followers’ News Feeds — though with the decrease in organic reach, it’s unlikely that everyone will see your post. The more people engage with your post, the more likely it is that the rest of your followers and their followers will see that activity.

Image Guidelines
Recommended upload size of 1,200 x 900 pixels.
Will appear in the feed at a max width of 470 pixels (will scale to a max of 1:1).
Will appear on the page at a max width of 504 pixels (will scale to a max of 1:1).

Shared Link – 1,200 x 627 (Recommended)

Another great tool in your Facebook belt is the ability to share a link. It’s very similar to posting a shared image, but it gives you even more fields to work with. You can choose to create a shared link with a small square image to the left and text on the right, or with a larger rectangular image on top with text underneath. Whichever ad you choose will permit you more fields to fill out with helpful information (a link headline, a display link and a description of the link) and the shared link will also click-through to the site of your choosing.

Image Guidelines
Recommended upload size of 1,200 x 627 pixels.
Square Photo: Minimum 154 x 154px in feed.
Square Photo: Minimum 116 x 116 on page.
Rectangular Photo: Minimum 470 x 246 pixels in feed.
Rectangular Photo: Minimum 484 x 252 on page.
Facebook will scale photos under the minimum dimensions. For better results, increase image resolution at the same scale as the minimum size.

Highlighted Image – 1,200 x 717 (Recommended)

A milestone is a great time to create a highlighted image. This image is going to be housed on your personal timeline, but it is going to take up a great deal more space than a shared link or image, so it’s a good place to celebrate the victories that keep you going!

Image Guidelines
Will appear on your page at 843 x 504 pixels.
Choose a higher resolution at that scale for better quality.


Being directly connected to Google search, Google+ can be a great way to increase your organization’s reach to members.

Profile Picture – 250 x 250 (Recommended)

Though you upload your image in a square format it’s going to render on your page as a circle, so be wary you don’t choose a photo that cuts out important details.

Image Guidelines
Minimum 120 x 120 pixels.
Recommended 250 x 250 pixels.
Maximum not listed – I was able to upload a 20 MB photo at 5,200 x 5,300 pixels.

Cover Image – 1,080 x 608

The Google+ cover image is the biggest photo on your page. It’s a great opportunity for you to showcase your organization and members.

Image Guidelines
Recommended 1,080 x 608 pixels.
Minimum 480 x 270 pixels.
Maximum 2,120 x 1,192 pixels.

Shared Image – 497 x 373

Google+ sharing is similar to that of other social networks, with one key difference: circles. With circles you can group people together based off of certain criteria that you deem relevant, and then share different images to different circles based off that demographics’ personality.

Image Guidelines
Appears in home stream and on page at a width of 426 pixels (height is scaled).
Minimum width of 497 pixels (will scale the height for you).
Maximum upload 2,048 x 2,048 pixels.

Shared Link – 150 x 150 (Thumbnail)

A shared link comes with the same ability to choose which circles you want to share with, but the post itself has different capabilities. You’ll still have the ability to type in whatever description that you’d like, but with a shared link you also have the opportunity to link your post to your site. This is going to pull a photo from your site and add it to the post so that your viewers can click through to your page.

Image Guidelines
Shows in the feed and on page as 150 x 150 pixels (pulls in photo from linked site).

Shared Video – Width of 496 Pixels
Just as with links and images you can pick and choose which circles would be best for each video.

Video Guidelines
Shows in the feed and on page as 497 x 279 pixels.


Pinterest can be an amazing social tool for driving referral traffic to your site. This is mostly due to the fact that 90% of Pinterest pages are external links. So it’s very important for you to make sure you’re optimizing your Pinterest page regularly and using proper image sizes for your boards and pins.

Profile Picture – 165 x 165

When setting up your Pinterest account you have the option to do so using Facebook, Twitter or email. If you choose Facebook or Twitter, Pinterest will pull in the profile image that you have set there. If you’re using email, or would prefer to use a different photo, you can do that too: just upload a square photograph (the larger the better) and Pinterest will resize it to fit. Like other social sites your profile picture on Pinterest should be something closely tied to you or your brand.

Image Guidelines
Appears at 165 x 165 pixels on home page.
Appears at 32 x 32 pixels on the rest of Pinterest.
Maximum 10 MB (wouldn’t allow me to upload anything larger).

Pin Sizes

When adding a pin to your board it’s important to remember that Pinterest puts a limit on the width of the image but not the length. This gives you the opportunity to add a photo that’s square or one that will scale to be even taller. Just remember to make sure you’re creating large images because they add more value, not just because you can.

Image Guidelines
Pins on main page appear as 236 pixels (height is scaled).
Pins on a board appear as 236 pixels (height is scaled).
Expanded pins have a minimum width 600 pixels (height is scaled).

Board Display

Creating boards is one of the most important things that you can do on Pinterest. It’s important to make sure you’re using an image that fits the size criteria perfectly. Not only is it important to choose a photo that is enticing to your audience, it’s important to choose one that’s relevant to that particular board.

Image Guidelines
222 x 150 pixels (large thumbnail)
55 x 55 (smaller thumbnail)


LinkedIn is the world’s largest professional network. Where other social networks may be good drivers of traffic and customers, LinkedIn is a great place for you to connect with other professionals in your area of interest.

Banner Image – 646 x 220 (Minimum)

In order to qualify as full HD, your dimensions must be at least 1,280 x 720 pixels.


Instagram is one of the most popular photo-sharing social networks with a user base of over 100 million people. It’s a great place for you to take and share fun or creative photos that show what you or you’re all about.

Profile Picture – 110 x 110

Instagram is based on photographs, which should be an indication of how important it is to pick a great one for your page. Instagram will automatically create a header that cycles through some of the photos that you post to the page, so it may be best to use your profile picture to create a static image of you or your brand.

Image Guidelines
Appear on your home page at 110 x 110 pixels.Square photo – make sure to maintain an aspect ratio of 1:1.

Photo Thumbnails – 161 x 161

When someone goes to your page they’ll be presented with all of your photos arranged in rows of thumbnails. These smaller renditions of your photos will expand when clicked, and will include a place for people to comment.

Image Guidelines
The thumbnails will appear on the page at 161 x 161 pixels.
Square photo – Make sure to maintain an aspect ratio of 1:1 ratio.

Photo Size – 640 x 640

Instagram is all about the photos. These pictures are going to appear in the feed of all of your followers. Instagram allows photos of a higher resolution if they are taken from the native Instagram application. If you decided to upload a photo taken from any other device the resolution will be much lower.

Image Guidelines
Instagram still scales these photos down to 612 x 612 pixels.
Appear in feed at 510 x 510 pixels.


Tumblr is customizable social site that lets users effortlessly share anything that they want. Due to the fact that almost everything is sharable, it isn’t hard to imagine that there are currently over 189 million blogs that have churned out more than 83 billion posts.

Profile Picture – 128 x 128

Although there is a profile photo associated with your Tumblr page it doesn’t appear very frequently throughout the site. It will appear as a thumbnail adjacent to your posts within a follower’s feed. It also appears next to the buttons to follow you on Tumblr when someone visits your page.

Your profile photo will also appear somewhere on your Tumblr profile page. Whichever theme you choose is going to play a part in where the photo appears and how large it is. Some brands choose a large image while others keep them subtler. Just make sure to mind the minimum and pick an image that fits not only your brand, but that also fits your page’s layout.

Image Guidelines
Minimum 128 x 128 pixels.

Image Posts – 500 x 750

These are the posts that you send out to your followers that will also appear on your page. Due to the fact that Tumblr is so customizable and each theme is so different, not all people are going to want to post the same size photos.

Image Guidelines
Dash image sizes max at 1,280 x 1,920, and show in feeds at 500 x 750
Images can’t exceed 10 MB.
Animated GIFS must be under 1 MB and max at 500 pixels.

Turning Members Into Brand Promoters

All too often our members don’t know the organization to which they belong. We send them emails and mailings that they delete. We invite them to membership meetings they don’t attend. We post information on our websites which they don’t view.

They do know their co-workers and often friend or follow them on social media. By turning your activist members into brand promoters, your union can expand its reach and engage members you currently are not reaching.

Use Hashtags

Make it easy for members to share about your organization using a unique hashtag with your organization’s name. #UnionName #UnionNameRally #UnionNameStrong. Encourage staff and activist members to use the designated hashtag for any organizational events. Adding hashtags with photos and updates on Twitter and Facebook will expand your organizations reach with their co-workers.

Analyze Your Reach

Hashtags are searchable and will provide you with additional metrics about your organizational reach. In addition to the Insights section of your Facebook page and Twitter Analytics there are multiple sites that will give you critical data about the reach, impressions and most influential people using your hashtags. Some of these sites require a fee while others provide limited free data. Check out and for examples.

Acknowledge Your Activists

Sharing, liking, favoriting and retweeting your activist members’ posts and photos on your social media sites will provide positive reinforcement, encouraging them to do it more often.

Give special shout-outs to your most influential members who participate. Using analytics mentioned above will show who these members are and the kind of reach they have to help get your message out.

Put Members in Charge

After analyzing the use of organizational branding in a few events, consider inviting in your most active members to brainstorm other ways they can help spread your organization’s brand in social media.

Do you have some worksites or parts of the state where you reach very few members? Consider making an activist member from that area an organizational promoter tasked with posting, sharing or retweeting something from the organization on a regular basis.

Sometimes the most influential person in a location isn’t an officer or building rep. Use your analytics to find out who the influentials are in your organization. Then recruit them to help build branding awareness.

Using Online Comments to Deliver Your Message

Online publications and blogs often allow comments. Some of these sites require you to sign up before commenting and give you the option of creating a username or giving your real name. Others require you to comment using Facebook.

Often these sites will only show the first few comments which are visible to everyone viewing the article. These comments can be a unique opportunity for your organization’s active members to help deliver your message.

AFT Connecticut’s Rapid Response Team

During the 2012 state legislative session, AFT Connecticut created a Rapid Response Team of more than twenty members willing to post comments on the issue of Education Reform.

The Response Team received a welcome email explaining what was expected of them:

Greetings AFTCT Response Team Member!

Articles, blogs, and editorials are being written every day about education reform. We are calling on you to be our voice on the Internet.

Each day we will be emailing you links to stories where we need comments. We will provide you talking points to help you write your comments.

Some of these sites require you to sign up before commenting and give you the option of creating a username or giving your real name. We will leave that to you as to which name you want to give. Others require you to comment using Facebook.

If each of you comments on 2-3 of these posts each day we will greatly increase the reach of our message on education reform.

Each day the Rapid Response Team received an email containing links to online news stories and blog posts about Education Reform and the issue(s) they covered. Team members were given talking points on these issues that contained the union’s message.

Articles and Blog Posts for Feb. 16

The New Haven Experiment
Talking Points: New Haven has shown that teachers, unions, and administrators can work together to develop an evaluation system that gives teachers the support they need while creating an efficient system for the removal of ineffective teachers.

“…only thing you have to do is show up for four years,” – Dan Malloy
Talking Points: If we are going to recruit and retain teachers, especially in our urban areas, we need a system that treats teachers with dignity and respect, and gives them the support they need to be successful.

Retiree Healthcare
Up next: Shared sacrifice for retired teachers
Talking Points: Teachers have to work 37 years before they can retire. The state must honor its promise to those retired teachers. Options like healthcare pooling can help reduce health care costs for retirees and the state.

Anti-Teacher Groups:
Michelle Rhee’s Unafraid To Stir Things Up, And Maybe That’s Not So Bad
Malloy to Join Anti-Teacher, Anti-Union Forces at Capitol
Talking Points: Michelle Rhee was an ineffective educator and a failed school chancellor in DC who refuses to work together with teachers. Now she’s funded by right-wing corporate groups intent on destroying teachers unions and public education. Connecticut needs people who are willing to work together, not a snake oil salesman like Rhee.

Two Hearings Next Week On Malloy’s Education Bill
Talking Points: Legislators need to listen to Connecticut’s 50,000 educators who are doing the work in the classroom every day. They understand best what works and what doesn’t.

End Result

Virtually every post contained at least one comment from a Rapid Response Team member. Over the course of the first month, there was an increase in comments that mirrored the organization’s message from non-Response Team Members. Several state legislators cited comments they had seen online as a gauge of public opinion on the issue.

Ultimately the education reform bill passed had the direct input of AFT Connecticut in the language. Whether online comments had a direct impact on this cannot be measured; however, there is evidence that shows that the tenor of comments can change the interpretation of the news story (

Creating a Rapid Response Team can be a useful way of engaging members who are very active online (e.g. social media) and expand your union’s message.

Vine Videos and How You Can Use Them

Vine videos are a great way to share breaking news, take your followers where they can’t go, and promote yourself in fun and creative six-second videos.

Video can take up a huge amount of space and depending on your member’s internet speed a long video could take a long time to be viewed. We are living in a world of instant access and using a Vine video to get your message out can help you be successful.

Here are some tips to help you use Vines successfully for your organization.

Use hashtags.

Be sure to include a hashtag for your organization (#ILCA) and possibly one for what’s in the video (#6secondrally)

Promote Events

Let’s face it, all of our members can’t be at every event, but posting a Vine of your event will engage them and make them feel a part of what your organization is doing. Rallies, actions and speakers all make for great Vines.

Call to Action

An image with a voice over is an easy Vine to create and give your members a call to action, like a shot of your state capitol and you saying “Call your legislators about the worker’s rights bill today.” #WorkersRightsBill and a link to the action page on your website.

Twitter Best Practices

Share timely news

If you want to be read and retweeted while keywords and hashtags are searched and shared, then you need to be trendy. You know what’s happening in your world. When you see that others are tweeting about something your organization cares about, note what hashtags they’re using and use them in your own timely tweets.

Share useful information

Have a special event coming up for your organization? A rally, lobby day or door knocking event? Tweet about it and add a hashtag to the tweet so non-followers searching the tag would see your tweet and can share it on.

Tell followers what to do

If people are following you need to tell people whether they should click a link or watch a video. Don’t assume people will click a link. Always include an action verb.

Remember pictures are worth 1,000 words

Pictures and/or videos make a difference if you want people to spend more time on your content. Pictures and video carry more influence than simple text or links. Include a picture of your members and give them a shout out in the tweet.

Share your passion

Rallying for an issue? Share it on Twitter with a picture and a hashtag. Need people to call their legislators? Tweet a link to the action page on your website. Promote the issues you care about.

Be strategic with your hashtags

Replacing “The Koch Brothers” with “#KochBros” will save you 8 characters and gain you viewers and followers. Take a look at other hashtags people are using and use the same ones to promote your issues. The hashtag is your friend but don’t overdo it. Keep it to two hashtags per tweet.

Retweet others who tweet about you

You shouldn’t retweet everyone who mentions you but doing it now and again will demonstrate a connection with your members.

Thank your followers

Dig into your followers and occasionally thank people especially those assisting your organization.

Go behind the scenes

Tweeting a photo of your staff working on an issue will show members how hard you are working for them. A simple photo of a staff meeting with a quick description and a hashtag for the current issue can carry a lot of weight with members.

Keep it simple

Keeping your tweets to 120 characters will give your followers the needed space for retweeting your message. Shaving 20 characters off the tweet could make or break getting your message out to a wider audience.

Twitter 101

Twitter is microblogging. Twitter and ‘tweeting’ is about broadcasting daily short burst messages to the world, with the hope that your messages are useful and interesting to someone. Conversely, Twitter is about discovering interesting people online, and following their burst messages for as long as they are interesting.

How Does Twitter Work?

Twitter is very simple to use as broadcaster or receiver. You join with a free account and Twitter name. Then you send broadcasts as often as you want. Go to the ‘What’s Happening’ box, type 140 characters or less, and click ‘Tweet’. You will most likely include some kind of hyperlink.

To receive Twitter feeds, you simply find someone interesting and ‘follow’ them to subscribe to their tweet microblogs. Once a person becomes uninteresting to you, you simply ‘unfollow’ them.

You then choose to read your daily Twitter feeds through any of various Twitter readers.

Twitter is that simple.

The maximum length of your username is 15 characters. But you can change it any time you like to anything that is available. And if you’ve gone with something Twitter recommended, and especially if you’ve got a number stuck at the end of your name because lots of people got there before you, then you really, really should. And the change is seamless – you don’t lose any followers or anything like that (although it’s worth announcing a username change if you have a lot of followers). Don’t change it all the time as that drives people crazy – find a good username and stick with it. Tip: the shorter your username, the better, as it makes it easier for people to re-tweet you and/or fit your tag within long tweets.

The maximum number of characters in a tweet is 140. But you should quickly get into the mentality of leaving at least 20 characters free to leave plenty of space for people to retweet you, as some people like to add comments to retweets. Indeed, I recommend writing tweets to a limit of 100 characters or less, which leaves plenty of room for a link and retweet space.

Any link you share on Twitter will automatically be shortened. This saves you space. Twitter converts (and shortens) every link into their internal shortener, which has great analytics. Alternatively, you can use if you want additional metrics.

You can only send a direct message to somebody if they are following you. And vice versa. (Note: you don’t have to both be following each other. Direct messages can be very one-way.) This is done to protect people from being bombarded with spam. If somebody is bugging you via direct message, unfollow them. Problem solved.

You don’t have to follow people back. You’re under no obligation to follow anybody. Twitter doesn’t work unless you’re careful to only follow people who are right for YOU.

If you start a tweet with @username, it’s a reply. And will only be seen by the person you replied to and people who are following both of you. Nobody else will see it in their stream (although it will show up on your profile page and in Twitter search).

If you tag a username anywhere but at the start of the tweet, everybody following you will see that message. This is called a mention. It’s important to quickly learn the difference between this and a reply, as above. (Some people have been using Twitter for years and still don’t know how this works.)

What’s a hashtag? Once you’ve started using Twitter, it won’t take long before you come across what’s known as a hashtag. That’s when you see something in a tweet that has a # prefix. (The # is a hash symbol, hence the term hashtag or, more commonly now, hashtag.) A hashtag is simply a way for people to search for tweets that have a common topic. For example, if you search on #Union (or #union or #UniON, because it’s not case-sensitive), you’ll get a list of tweets related to unions. What you won’t get are tweets that say, “Why is a union awesome?” because “union” isn’t preceded by the hashtag.

The easiest way to find people you know on Twitter is on Google. Go to Google and type in Twitter first name last name – if the person you’re searching for isn’t sharing their name with a million other people they will almost always be the first result.

Putting the “Social” Back in Social Media

Are Facebook and Twitter just secondary websites for your organization? Or are you using social media to engage your members?

While posting information that directs members to your website is important, perhaps more important are posts that engage or respond to members.

Want to poll your members? Use Facebook’s Polling App.

Remember. It’s called “social” media and people want to socialize. Ask your members questions to get their input on issues. Their comments will help generate conversation and demonstrate you value their opinion.

Members are more likely to ask a question or raise a concern on your social media site than via email or phone. These questions will be publicly viewable by everyone and how you respond can be a make or break moment for you. Members often show their appreciation for quick responses by commenting and that’s the best kind of endorsement your organization can receive.

Don’t forget to be proactive on issues by posting helpful information on critical issues.

Two-way communication is the key to a successful social media site.
