Social Media Image Size Guide 2026 | All Platforms

Getting your social media image sizes right is crucial for looking professional across platforms. Each social network has its own optimal dimensions for profile photos, cover images, posts, stories, and ads. Using the wrong size means your images get cropped awkwardly, appear blurry, or lose important elements. This comprehensive guide covers every image size you need for all major platforms in 2026.

Instagram Image Sizes

Square Post: 1080×1080 pixels (1:1 ratio)

Landscape Post: 1080×566 pixels (1.91:1 ratio)

Tips for Social Media Images

Always export at 2x resolution when possible for retina displays.
Use PNG for graphics and text-heavy images, JPEG for photos.
Keep file sizes reasonable — large files load slowly and may be compressed by the platform.
Design for mobile first — most social media is consumed on phones.
Leave safe zones around edges — different devices crop images differently.
Test your images on multiple devices before posting.

Frequently Asked Questions

Q: What happens if I upload the wrong image size?

The platform will automatically resize and/or crop your image, which often leads to cut-off text, blurry images, or awkward framing.

Q: What's the best image format for social media?

JPEG for photos (smaller file size) and PNG for graphics, logos, or images with text (better quality for sharp edges).

Q: Do these sizes change often?

Platforms occasionally update their image specs, usually once or twice a year. We keep this guide updated as changes happen.
