Social Media Image Size Guide

Look up recommended image sizes for popular platforms.

Social Media Image Size Guide speeds up a repetitive writing or editing step that comes up often when preparing a post. With Social Media Image Size Guide, you can get this done in seconds instead of doing it by hand. The whole process happens locally in your browser; nothing is sent to a server.

Step-by-step

Choose where the image is going from the Platform list: Instagram Post, Instagram Story, Facebook Post, X/Twitter Post, LinkedIn Post or YouTube Thumbnail.
Click Run and note the recommended size.
Start your design file at exactly that size. Designing at another size and cropping later often pushes text and logos too close to the edge.
If the same content is going to several platforms, select each one in turn and compare the dimensions.

Example

You're announcing a café's weekend brunch menu and want to share it as both an Instagram post and a story. Selecting Instagram Post and then Instagram Story shows two very different aspect ratios. A square post design dropped into a story leaves empty bands at the top and bottom. Making two versions, each with the food photo and the menu text placed for its own frame, looks much cleaner.

Why does the right image size matter?

The guide lists these sizes: Instagram Post 1080×1080, Instagram Story 1080×1920, Facebook Post 1200×630, X/Twitter Post 1600×900, LinkedIn Post 1200×627 and YouTube Thumbnail 1280×720. Platforms may crop or compress images to fit their space; prepared at the right ratio, the important parts stay uncut.

Practical tips

Keep important text and faces in the middle, away from the edges.
Platforms can change over time; confirm the current size on the platform's own help page before publishing.
If you reuse one design across platforms, prepare a separate ratio for each.

Common mistakes

Putting a landscape image into a portrait slot and letting it be cropped badly.
Enlarging a low-resolution image, which makes it blurry.
Setting text so small it cannot be read on mobile.

Things to keep in mind

In story formats, the top and bottom of the screen are covered by the profile name, reply box and other interface elements. Keep important text and logos in the central safe area.
Aspect ratio matters more than exact pixels. If the ratio is right, the platform can scale the image down without cropping it.
YouTube thumbnails are often seen at a tiny size. A bold title of a few words reads better than a full sentence.
Platforms recompress images on upload. Starting from a high-quality source file reduces the blur that creeps in afterwards.
