Image Guidelines for 6 Major Social Networks

We’ve got all tools to create mind-blowing images for social media. We all understand that the brain loves visuals and how to build something beautiful to drive engagement. You’re all set to make something great!

Just one last thing before you start rocking you social media accounts. Exactly how should your image look to maximize the viewing in your News Feed, timeline, or stream?

With everything that goes into finding and creating great social media images, the one thing that many of us forget about is the size. This can be a grave mistake as the size, shape, height, width and orientation are all extremely important and have a huge effect on how well your image is received in social media streams.

Facebook and Twitter now give users some added control when adding profile and cover photos. Facebook allows you to reposition the cover photo in order to get it just the way you want it.

That was just a quick note on the cover and profile photos, but the focus of this article is on the images that we share on social media platforms.

Size Guide for Sharing Social Media Images

 Did you know that tweets with images get 150% more retweets than those tweets that do not have images?

The first question you always have to answer is how to get an engaging image to look its best in a stream, timeline or News Feed?

Generally speaking, these are the sizes that work best on the various social media sites.

Facebook – 1,200 x 628

Twitter – 1,024 x 512

LinkedIn – 800 x 800

Google+ – 800 x 1,200

Pinterest – 735 x 1,102

Instagram – 640 x 640

There are a couple of "go-to" sizes to make life fast and easy across the board. Here are the image sizes for both a horisontal and a vertical image:

  • Horizontal (landscape) – 1,024 x 512
  • Vertical (portrait) – 800 x 1,200

Note: If you’d like to grab either of these as a Canva template (built in image creator within SmartSocial), we’d love to make this easy for you. Click here for the horizontal template; click here for the vertical template.

In general, I would suggest using the horizontal size for sharing on Facebook and Twitter and to use the vertical size for sharing on Google+ and Pinterest.

The horizontal size fits perfectly in Twitter, but it is just slightly off on Facebook. We feel the time saver in regards to image size is worth the tiny bit that gets cropped on Facebook.

If you are a fan of square images, this is a good size to follow:

  • Square – 1200 x 1200 (share to Facebook and LinkedIn)

Facebook image sizes for posts

Facebook determines which dimensions it will use based on the orientation of your image.

When uploading a square image, it will be 470 pixels square, the maximum allowable size in a Facebook feed. This is the case no matter what size square you upload, be it an 800 x 800 image or a 400 x 400 image (the smaller images might appear a bit blurry when they are sized up to 470 pixels square).

If you upload a horizontal (landscape) image, it will be scaled to 470 pixels wide and the height will be adjusted accordingly.

fb image2

Landscape images smaller than 470 pixels wide could appear at less than the 470-pixel width, aligned left with whitespace to the right of the image.

If you upload a vertical (portrait) image, it will be scaled to a height of 394 pixels, aligned to the left, with white space to the side. The adjusted width will be relative to the 394 pixels. For instance, if you upload a 500 x 700 image, Facebook will resize it to 281 x 394 pixels.

Sharing links to Facebook (and the images that come with them)

If you share a link to Facebook, the image associated with the link can be displayed in a number of ways. Again, all depends on the image size and orientation.

Images previews for shared links are scaled to fill a box of 470 pixels wide by 246 pixels tall.

When choosing an image to go along with a link, Facebook looks at the Open Graph tags for a page, specifically the og:image tag, which specifies the image that Facebook should use when sharing in the News Feed.

You can add the og:image tag manually into the <head> section on every page of your website.

If you are creating an image to be used in the og:image tag for your link, keep in mind that anything outside of 470 x 246 pixels will be cropped from the top and bottom in order to fit.

Additionally, if the link you share does not have the proper og:image tags installed or the image in the tag is not large enough, Facebook will not display it full-width. A thumbnail image will be placed in a small box to the left of the link text.

For most all image orientations—square, horizontal (landscape), and vertical (portrait)— the thumbnail will be scaled and cropped to fit a 158 x 158-pixel square.

In certain cases, very tall images (like infographics, for instance) will have 158-pixel width and 237-pixel height.

facebook tall thumbnail 800x589

We’ve found the best solution for creating and sharing images to Facebook is to build an image that is 1024 x 512. While this doesn’t quite fit the dimensions above perfectly, it is large enough to look great on retina displays (where the pixel density is greater) and large enough so as to fit with the full-width areas in the News Feed.

Twitter image sizes

On desktops, Twitter images appear in the timeline at 506 pixels wide by 253 pixels tall.

This size works out to an aspect ratio of 2:1, meaning that for every two pixels wide, your image is one pixel as tall. If you create images at 800 x 400 or 1,000 x 500—any size within the 2:1 ratio—the image will appear fully in tact in the Twitter stream.

Here’s an example of an image that is 1,024 pixels wide by 512 pixels tall (a 2:1 ratio), scaled to fit the 506 x 253 frame.

twitter landscape1 800x479

(Note: Uploading an image that is smaller than 506 pixels x 253 pixels will result in whitespace to the right of the image.)

If the dimensions fall outside the 2:1 aspect ratio, Twitter crops the image to fit, and the full size can be viewed only by clicking the image.

Twitter has a neat way of cropping these images. In lieu of a dominant visual, Twitter will crop from the top and bottom, leaving the middle of the image as-is.

Image sizes for Twitter cards

Images are also present in each of the nine different Twitter Cards. I’d like to get a bit deeper into a couple of specific ones that seem key for content sharing.

  • Summary card
  • Summary card with large image

Summary cards show a headline, description, link, and photo when you share a url from a site that contains the appropriate Twitter Cards code. All this information is pulled via HTML tags, often the same ones that are being used by Facebook to display links.

Each type of summary card contains a thumbnail or featured image.

For summary cards:

The image must be a minimum size of 120px by 120px and must be less than 1MB in file size.

For an expanded tweet and its detail page, the image will be cropped to a 4:3 aspect ratio and resized to be displayed at 120px by 90px.

The image will also be cropped and resized to 120px by 120px for use in embedded tweets.

twitter cards small thumb 800x394

Update: Small-image Twitter Cards now use a size of 109 pixels by 82 pixels, not the 120px x 90px mentioned above.


For summary cards with large images:

Images for this Card should be at least 280px in width, and at least 150px in height. Image must be less than 1MB in size.

All images for the large-image cards will be scaled to fit a width of 480 pixels. So landscape and portrait images will be resized to 480 wide and however many pixels tall (there doesn’t seem to be a maximum or a minimum here). Square images will be resized to 480 x 480 square.

Any image smaller than 480 pixels will appear aligned to the left with whitespace filling the empty space to the right.

twitter card large summary 597x800

Update: Large-image Twitter Cards now use a width of 506 pixels, not the 480-pixel width mentioned above.

One thing that’s interesting to note here is where the images get cropped. For the basic summary cards, photos will be cropped in the following ways:

  • Square and portrait images will be cropped from the bottom up and not from the sides.
  • Landscape images will be cropped from the outside in, and not from the top or bottom.

For the summary cards with large images, there don’t appear to be any noticeable crops.

If you’re curious how your images might look with Twitter Cards, you can enter your link into Twitter’s free card validator to get a quick preview.

LinkedIn image sizes

When you share links and articles to LinkedIn, the thumbnail photos appear at a maximum of 180 pixels wide by 110 pixels tall.

linkedin thumbnail 800x244

If you upload an image directly, the image will appear at a maximum width of 350 pixels. The height of the image—whether square, landscape, or portrait—will be scaled to fit the new width. For example, a 700 x 500 image will be scaled to 350 x 250.

linkedin large upload 800x332

One outlier among these standard sizes is for LinkedIn’s Showcase Pages, a feature that allows companies to create pages based on offshoots of their brand (for instance, Adobe created pages for Adobe Creative Cloud, Adobe Marketing Cloud, etc.)

On these pages, thumbnail and featured images for links appear either at the standard size of 180 x 110 or at a larger size of 442 x 248.

LinkedIn uses the same Open Graph tags as Facebook and other social networks. If you’ve got your site well-optimized for Facebook links, then you should be good to go for LinkedIn as well.

One additional way to share content on LinkedIn is by publishing articles that appear on people’s home pages via LinkedIn Pulse. LinkedIn built a substantial publishing platform for this content, which includes the ability to add featured images to the articles.

In the home page feed, the featured image on a Pulse update is 180 pixels wide by 110 pixels tall—same as it is for all link thumbnails. If the story is placed in the recommended reading list below a featured Pulse story, the thumbnail will be 70 x 37.

linkedin pulse homefeed 800x431

Inside the Pulse page, a list of articles runs along the left-hand column. The image thumbnails here are 70 x 70 square images.

The featured image at the top of the article is 698 pixels wide by 400 pixels tall.

(Cropping for these images occurs from the outside in, so the very middle of the picture will be what’s displayed in the smaller thumbnails.)

Google+ image sizes

When you share links and articles to Google+, the featured photos appear at a maximum width of 426 pixels. The height scales accordingly.

Similarly to the other social channels mentioned here, Google+ pulls in images from URLs using Open Graph tags. If the image used in the Open Graph is not at least 426 pixels wide or if Open Graph tags do not exist for a url, Google+ may instead place a thumbnail image to the left of the update. This thumbnail is 150 x 150 square.

If you upload an image directly to Google+, the image will appear at a maximum width of 426 pixels also (same as above). The height of the image will scale to fit according to the new width.

Clicking through to the update URL, the image will be 506 pixels wide, maximum, with a height that scales accordingly.

url page g 800x581

If the image is smaller than the 346-pixel width, Google+ places the image centered on the update with white space to each side.

One other way that Google+ may display photos is as a full-width image that spans across both columns of the Google+ stream. These images are 886 pixels wide. The height scales accordingly.

Pinterest Pins image sizes

There are a couple of different places where a Pinned image can appear on Pinterest.

In the feed, Pinterest images have a width of 235 pixels. The height scales accordingly.

pinterest size 800x723

If you click to expand a Pinned image, the image will have a width of 736 pixels. The height, again, scales accordingly.

pinterest width 800x425

Beyond these two places, the other spots that you might find a pin include the cover for Pinterest boards and in side ads for recommended and related Pins.

According to Pinterest, the best aspect ratio for Pinterest images is between 2:3 and 1:3.5, with a minimum width of 600 pixels. 

So this might raise the question (one that I’ve asked a lot before): What isaspect ratio?

It’s how the width and the height of an image relate to one another.

For instance:

A 2:3 aspect ratio could be

  • 600 pixels wide by 900 pixels tall
  • 800 pixels wide by 1,200 pixels tall

A 1:3.5 aspect ratio could be

  • 600 pixels wide by 2,100 pixels tall
  • 800 pixels wide by 2,800 pixels tall

Pins with an aspect ratio greater than 1:3.5 will be truncated in the feed, cropped from the bottom up with a small “Expand Pin” link covering the bottom. If a user clicks to expand, the cropped portion of the image appears.


Ideal image sizes for Instagram photos

Instagram makes things pretty easy. Every image on Instagram is a square.

The Instagram photos in a feed appear 510 pixels wide by 510 pixels tall.

instagram feed 697x800

The thumbnail photos that appear on one’s profile page are 161 x 161.

instagram thumbnails 800x478

The images in the header are either 204 x 204 (for the smaller featured images) or 409 x 409 (for the larger featured image).
