Your image size guide on social media

Posted by Lisa Seymour

Size matters, or at least on social media. Social channels are visual led so making sure your assets are not too big and not too small can be daunting. To make things easier, we’ve rounded up what you need to know for the top four channels:

Instagram

Facebook

Twitter

LinkedIn

But is there a one size fits all option? Unfortunately not, but there some tips we can share:

  • Aim for assets with a width of 1200 pixels
  • If in doubt, share square. While square images will be displayed with cropped thumbnails on Twitter feeds, Instagram loves them and they’re a safe bet for Facebook and LinkedIn.
  • Stories provide an opportunity to fill the full screen. These need to be a ratio of 9:16 with a resolution of at least 1080 pixels wide by 1020 pixels tall to pack that punch.
  • Ensure the most important elements of your image are central, in case of unexpected cropping
  • If you’re sharing multiple images, the platform will crop the image thumbnails to make them work on their respective news feeds. When clicked you should be able to view them as a carousel, but this is something to be aware of if you need maximum impact.
  • Clipped text on thumbnails NEVER looks good, so pay extra attention if your assets have text on them. If sharing assets with text on Instagram remember images on your profile are tiled – so text that’s not clipped on the feed may be clipped here if the image is not a square (1:1)
  • Make sure your assets are JPG/JPEG/PNG files
  • Cropping or scaling an image down that is too large is easy, but even with sophisticated tools like Photoshop digitally enlarging an image will result in less than crisp and clear results.
