Image Sizes for Every Social Media Platform

Few things make a brand look more amateur than a profile picture that's awkwardly cropped or a cover photo cut off at the worst possible spot. Every social platform has its own preferred image dimensions, and getting them right is the difference between a polished presence and a sloppy one. Here's a practical guide.

Why size matters so much

Upload an image at the wrong aspect ratio and the platform crops it automatically — usually badly, chopping off heads or text. Upload one too small and it looks blurry and pixelated when stretched. The fix is simple: size each image correctly before uploading.

The dimensions that work

Exact pixels shift as platforms update, but these reliable ratios rarely change:

• Profile pictures: square (1:1), commonly 400×400. Displayed as a circle on most platforms, so keep the subject centred.
• Landscape / shared posts: 1200×630 (1.91:1) works almost everywhere, including link previews.
• Square posts (Instagram feed): 1080×1080.
• Vertical / Stories & Reels: 1080×1920 (9:16) to fill the phone screen.
• Cover / banner images: wide and short — check each platform, as these vary most.

How to resize without distortion

The key is matching the aspect ratio so nothing stretches. Use our image resizer to set exact dimensions, and the image cropper to frame the important part before resizing. Crop first to the right ratio, then resize to the target pixels.

Keep file sizes down too

Big files load slowly and some platforms compress them harshly, hurting quality. Compress images with the image compressor before uploading, and consider the right format for the job.

Design with safe zones in mind

Keep important text and faces away from the edges, where cropping and overlaid interface elements (profile photos on cover images, captions on Stories) can hide them. A little margin keeps your message visible everywhere.

Bottom line

Match each image to the platform's aspect ratio, size it for sharpness, compress it for speed, and keep key elements clear of the edges. Get those right and your brand looks deliberate and professional across every feed — for free, in a couple of minutes per image.
