Social media is all about engagement – being seen, followed and gaining those crucial likes and shares – but imagery plays a big part in this too! 

With visuals needed across social platforms for posts, stories, covers, profile photos, events, ads and more it’s a good idea to note the various optimum sizes for each of these for both desktop and mobile. The devil’s in the detail and its best to get the sizes right at the point of design and avoid time-consuming mistakes. 

As a small business owner juggling digital marketing and social media amongst many other daily tasks can be hard and it’s difficult to keep track of…so let’s talk pixels, proportions and ratios – if you’re getting them wrong, you’ll be doing your brand a disservice. 

Here’s a round-up of the latest social size guidelines needed across four of the largest platforms, simply pin this cheat sheet somewhere handy and refer as needed. You can thank us later!


For Facebook, some of the main images needed are covers, profiles, posts, stories and ads. Here are the best sizes for each:

  • Page Cover: according to Facebook, page cover photos display at 820 pixels wide and 312 pixels tall on desktop and 640 pixels wide by 360 pixels tall on mobile. Because of this difference – and Facebook will crop a photo to fit where it needs to – it’s best to design to 820 pixels by 360 pixels and keep the information within a safe zone not going too near any of the edges. Keep file size less than 100kb and don’t forget covers can be videos too – these need to be between 20 and 90 seconds long and 820 pixels wide by 426 pixels tall with a resolution of 1080p. 
  • Event covers: these are best sized at 1920 by 1080 pixels which is an aspect ratio of 16:9, anything smaller and quality will be lost.   
  • Profile photo: these need to be an aspect ratio of 1:1 or in other words, square. A minimum of 170 by 170 pixels on desktop and 128 by 128 pixels on mobile. A larger size of 400 by 400 will provide better quality and is great for a lot of social platforms. Bear in mind on Facebook that this square shape will be cropped to a circle for ads and posts
  • Photo posts: finally some flexibility! Photos and images can be many sizes but a good one is 1200 by 1200 pixels for portability across other platforms or 1080 by 1080 pixels can also work as can anything with an aspect ratio of 2:3 or 4:5 
  • Video posts: again there’s flexibility here but a good rule of thumb is a landscape ratio of 16:9 and a portrait ratio of 9:16 and a max file size of 4gb.  
  • Ads: with many different advertising options on Facebook, it’s important to note these sizing options… 
    • News feed ads:
    •  Marketplace ads and Messenger ads – 1200 by 628 pixels
    • Collection ads: 400 by 150 pixels
    • Carousel ads – 1080 by 1080 pixels
    • Video ads – ratio: 16:9 or 9:16, 4GB Max


LinkedIn is a great place to really highlight your brand and these image guidelines will help:

  • Business profile photo: 400 by 400 pixels
  • Cover photo: 1536 by 768 pixels
  • Post images: 1200 by 628 pixels


Over recent years Instagram has thankfully expanded on its square size to offer three options:

  • Square Image: 1080 by 1080 pixels
  • Vertical Image: 1080 by 1350 pixels
  • Horizontal Image: 1080 by 566 pixels
  • Stories: 1080 by 1920 pixels, a 9:16 aspect ratio and a max 4gb file size. 
  • Profile Image: aim for 110 pixels by 110 pixels with a 1:1 aspect ratio.


Fast-paced Twitter is often thought of as a primarily text-based medium but images help engagement here too and here are your sizes:

  • Header photo: 1500 by 500 pixels
  • Profile photo: 400 by 400 pixels
  • Shared images: 440 by 220 pixels (minimum), 1024 by 512 pixels (maximum).

We hope this cheat sheet comes in useful!
