Social Media Image Sizes: A Practical Cheat Sheet (and How to Resize Without Stretching)

Updated 27 September 2026 · 3 min read

Upload the wrong shape and a platform will crop your photo for you — usually through someone’s head or the middle of your headline. Upload one that’s too small and it looks soft on high-resolution phones. Getting it right is mostly about the shape (the aspect ratio) and giving the platform enough pixels. Here are the sizes that matter and the quickest way to produce them.

Platforms redesign their layouts often, and some show images differently on phones and computers. Treat these as dependable starting points and preview a post before publishing anything important.

Resize without stretching: crop to shape first

The most common mistake is typing new width and height values that don’t match the photo’s shape, which squashes or stretches everything in it. Faces look wide, circles become ovals. The fix is to crop the photo to the right shape, then scale it.

  1. Open the Social Media Image Resizer and choose your photo (iPhone HEIC photos work too).
  2. Pick the preset — for example “Instagram post (portrait) — 1080 × 1350”.
  3. Drag and zoom the photo inside the frame so the important part sits where you want it.
  4. Download. The image is cropped to the exact shape and size in one step.

For a size that isn’t in the list, crop to the shape with the Image Cropper, then set the width in the Image Resizer with Keep proportions switched on.

Safe zones: where not to put text

  • Stories and Reels (9:16): the top and bottom of the screen are covered by the profile name, caption and buttons. Keep text and faces in the middle area.
  • Profile banners: your profile picture overlaps part of the banner, and the visible area changes between phone and desktop. Keep key text central.
  • Grid previews: Instagram’s profile grid shows posts cropped to a tall rectangle, so edge details can disappear there.
  • YouTube thumbnails: the video length appears in the bottom-right corner.

JPG or PNG?

Photos: JPG. Graphics with text, logos or flat colours: PNG keeps edges crisp. Platforms recompress uploads either way, so give them a good-quality original rather than a heavily compressed one.

Keep files sensible

Most platforms accept large files, but smaller images upload faster on mobile data. For images on your own website — where every kilobyte affects loading speed — compress them with the Image Compressor at 75–85% quality.

Profile pictures

Almost every platform displays profile pictures as a circle, cropped from a square. Use a square image of at least 400 × 400 pixels, with your face centred and some space around it so the circle doesn’t clip your head. The Profile Picture Maker crops photos to a clean square.

Frequently asked questions

What size is an Instagram post?

1080 × 1080 pixels for square posts and 1080 × 1350 for portrait posts, which take up more space in the feed.

Why does my image look stretched?

The width and height were changed without keeping the original proportions. Crop to the right shape first, then resize with proportions locked.

Why do my photos look blurry after posting?

Usually the image was too small or already heavily compressed. Upload a larger, good-quality original and let the platform scale it down.

Are my images uploaded to KitWren?

No. The image tools run in your browser, so photos stay on your device until you post them yourself.
