The Ideal Image Sizes for Your Social Media Posts: Guidelines for All 6 Major Social Networks

Google+ – 800 x 320 Our two favorite image size templates that cover most networks
In experimenting with the fastest, easiest way to create images we know will work well in social media feeds, we came across a couple of image sizes that became our go-tos: one size for horizontal (landscape) images and one for vertical (portrait) images. Horizontal (landscape) – 1,024 x 512 Vertical (portrait) – 800 x 1,200
One of the simplest ways we’ve found for creating the 1,024 x 512-pixel images is to use Pablo . You can create an image in under 30 seconds and share directly to Twitter, Facebook, and Buffer.
We use the horizontal size for sharing to Facebook, Twitter, LinkedIn, and Google+.
We use the vertical size for sharing to Pinterest.
(We have also recently been experimenting with square images — 1024 pixels wide by 1024 pixels tall.

)
The horizontal size isn’t quite spot on. But that’s alright because, as you’ll read below, most platforms now adjust the height of the images accordingly without cropping the images.

Even when they do crop, we’ve found that it’s close enough where no important bits get cropped. Ideal image sizes for Facebook posts Sharing images to Facebook
The orientation of your image—whether it’s horizontal (landscape), vertical (portrait), or square—will determine which dimensions Facebook uses to show your image.
If you upload a square image to share, it will be 476 pixels square . This’ll be 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 476 pixels square).
If you upload a horizontal (landscape) image, it will be scaled to 476 pixels wide and the height will be adjusted accordingly.
If you upload a vertical (portrait) image, it will be scaled to 476 pixels wide and the height will be adjusted accordingly but to a maximum of 714 pixels tall.

Facebook will crop away the bottom of the image beyond the 714 pixels.
If you plan on sharing multiple images in the same Facebook post, there are some great insights at Have Camera Will Travel that cover all the various options that ensue here. 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 (pixel width and height) and shape (orientation).

Images previews for shared links are scaled to fill a box of 476 pixels wide by 249 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 section on every page of your website, or you can try out a plugin like Yoast SEO for WordPress , which handles the code and implementation for you. (We’re big fans of the Yoast plugin for the Buffer blog.)
If you are creating an image to be used in the og:image tag for your link, keep in mind that anything outside of 476 x 249 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 or might not display an image preview at all.

If it does, 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.
If you add multiple images to a link post, Facebook will automatically convert it into a carousel post. Each image is cropped to fit a 300 x 300-pixel square.
What we’ve found to be a great 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.

(And as you’ll see below, this image size is ideal for Twitter as well.)
If you want to make sure that your photos display in the highest possible quality, Facebook has some advice for you.

Ideal image sizes for tweets
Twitter images used to appear on the timeline at 506 pixels wide by 253 pixels tall. Now, Twitter images appear bigger and less cropped when viewed on a desktop. Sharing a single image to Twitter
On the desktop, regardless of the orientation of your image — horizontal (landscape), vertical (portrait), or square — it will be scaled to 506 pixels wide and the height will be adjusted accordingly but to a maximum of 747 pixels tall. The top and bottom of the image will be cropped away.

So a square image will nicely take up all the space available.
But if you upload an image that is smaller than 506 pixels wide by 253 pixels tall, there will be a whitespace to the right of the image.
Note: On mobile, images will be cropped into a horizontal rectangle. From my tests, it seems that 1024 pixels wide by 576 pixels tall is the ideal Twitter image size for displaying your image fully on mobile.

(This dimension also works great on the desktop.) Sharing multiple images to Twitter
Twitter also allows you to upload up to four images to each tweet. The images used to be displayed as four equal horizontal rectangles but now, they are cropped into squares and the first image you upload will appear bigger.
The featured image will be scaled to various sizes depending on the number of photos you upload and cropped into a square: Two images: Scaled to 252 pixels tall and cropped to 252 pixels wide Three images: Scaled to 337 pixels tall and cropped to 337 pixels wide Four images: Scaled to 379 pixels tall and cropped to 379 pixels wide
The remaining images will also be scaled and cropped into squares.
Note: On mobile, images will be cropped differently.

Here’s an overview of the aspect ratios, from Twitter : Image sizes for Twitter cards
Images are also present in each of the nine different Twitter Cards . If you’re interested in trying out something like a lead generation card or a product card, Twitter did a great job of breaking down the images sizes for each type of card . 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.

(The Yoast SEO WordPress plugin mentioned above also includes support for Twitter Cards.)
Each type of summary card contains a thumbnail or featured image.
The image must be a minimum size of 144 pixels wide by 144 pixels tall and must be less than 5MB in file size.
The image will also be cropped into a 125×125-pixel square.
The image should be at least 300 pixels wide by 157 pixels tall.

Image must be less than 5MB in size.

The image will be cropped into a rectangle with a 2:1 aspect ratio.
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. Ideal image sizes for Instagram photos Sharing photos to Instagram
Instagram used to be all about the square image. However, you can now upload landscape (horizontal) or portrait (vertical) photos as well.

Here are the best sizes for Instagram’s three image types: Square image: 1080 pixels wide by 1080 pixels tall Vertical image: 1080 pixels wide by 1350 pixels tall Horizontal image: 1080 pixels wide by 566 pixels tall Square Vertical (Portrait) Horizontal (Landscape)
The thumbnail photos that appear on one’s profile page are 293 pixels wide by 293 pixels tall. Sharing Instagram stories
Instagram stories are displayed at an aspect ratio of 9:16. So the ideal size for Instagram stories is 1080 pixels wide by 1920 pixels tall.
So the ideal size for Instagram stories is 1080 pixels wide by 1920 pixels tall.

Ideal image sizes for LinkedIn posts Sharing to your LinkedIn personal profile
According to a moderator of LinkedIn’s help forum , the ideal image size is 522 pixels wide by 368 pixels tall.
If you upload an image directly, the image will appear at a maximum width of 552 pixels and a maximum height of 368 pixels. The image will be cropped to fit this box.
It seems that if you upload a landscape image, LinkedIn will scale it to a height of 368 pixels and crop the sides.

If you upload a portrait or square image, LinkedIn will scale it to a width of 552 pixels and crop the bottom of the image.
(LinkedIn only crops the image preview. People can still see the full image by clicking on it.)
When you share links and articles to LinkedIn, the image preview will be scaled and cropped to fit a box of 520 pixels wide by 272 pixels tall.

Sharing to your LinkedIn Company Page
Images shared to your LinkedIn Company Page will look slightly different than images shared to your personal profile. Images will be scaled to fit into a 436-pixels-wide-by-228-pixels tall rectangle.
LinkedIn doesn’t seem to crop images when they don’t fit that box. It scales the images and adds gray spaces accordingly.
If an image is too wide (e.g.

landscape), LinkedIn will scale it to 436 pixels wide, adjust the height accordingly, and add gray spaces to the top and bottom of the image. If an image is too tall (e.g. square or portrait), LinkedIn will scale it to 228 pixels tall, adjust the width accordingly, and add gray spaces to the left and right of the image.
When links are shared to your Company Page, the image preview will be scaled and cropped to fit a box of 436 pixels wide by 228 pixels tall.
This is a different size from when links are shared to your personal profile.

The good news? It’s almost the same aspect ratio as the image preview of links shared on your personal profile. So the same image should scale nicely for both image previews of links on your personal profile and Company Page. Sharing to your LinkedIn Showcase Pages
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.), display images in a slightly different size but resizes them in the same ways: On these pages, images and image preview for links will appear in a box of 366 pixels wide by 191 pixels tall (roughly the same aspect ratio as those above). Images will be scaled and gray spaces will be added accordingly. Image preview for links will be scaled and cropped to fit the box.
According to eDigital , the ideal image size for your LinkedIn Company Page is 1200 pixels wide by 628 pixels tall.

This size seems to work great for all the various image types — images on your personal profile, Company Page, and Showcase Pages.

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. Images in LinkedIn articles
One additional way to share content on LinkedIn is by publishing articles that appear on people’s home pages. 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 LinkedIn article has the same size as that of a link shared on LinkedIn — 520 pixels wide by 272 pixels tall .
The recommended size for the cover image at the top of the article is 744 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.) Ideal image sizes for Pinterest Pins
There are a couple of different places where a Pinned image can appear on Pinterest.

In the feed, Pinterest images have a width of 236 pixels. The height scales accordingly, to a maximum of 800 pixels. If a user clicks to expand, the cropped portion of the image will appear.
If you click to expand a Pinned image, the image will have a width of 564 pixels . The height, again, scales accordingly.

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 2:3, with a minimum width of 600 pixels.
So this might raise the question (one that I’ve asked a lot before): What is aspect 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 Ideal image sizes for Google+ posts Sharing images to Google+
If you upload an image directly to Google+, the image will appear on the feed at a maximum width of 431 pixels . The height of the image will scale according to the new width.

Clicking through to the update URL, the image will be 530 pixels wide, maximum, with a height that scales accordingly. Sharing links to Google+
When you share links and articles to Google+, the featured photos appear at a maximum width of 426 pixels also (same as above).

The height scales accordingly.
According to Google , the image must be sized as follows: must be at least 400px wide. must have an aspect ratio no wider than 5:2.
From that, I think it’s safe to say that 800 pixels wide by 320 pixels tall will be an ideal image size for Google+.
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 400 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 110 x 110 square.

Summary
I hope these image size overviews might be useful for you. We continue to learn lots about what’s best for all the different social networks, and I’ll be happy to continue updating this post with all our latest findings.
(I’m also eager to experiment with mobile sizes as well!)
Is there anything we can add to this resource to make it more useful for you? What has your experience been with sharing different image sizes to social media?
