What is the best size for Instagram feed posts?

Use 1080px on the longest side: 1080×1080 for square, 1080×1350 for portrait (4:5), 1080×566 for landscape. Instagram displays at 1080px, so going higher does not improve quality.

What size for Instagram Stories and Reels?

Use 1080×1920 px (9:16). Crop to 9:16 first, then resize to 1080×1920 so the image fills the screen without letterboxing.

Resize Image for Instagram – Sizes & Guide

Instagram has specific recommended dimensions for feed posts, stories, and reels. This guide covers the exact sizes to use and how to resize and crop your photos so they look sharp on the platform.

Recommended image sizes for Instagram

Square (1:1): 1080×1080 px — feed and profile
Portrait (4:5): 1080×1350 px — vertical feed
Landscape (1.91:1): 1080×566 px — horizontal feed
Stories & Reels: 1080×1920 px — 9:16 vertical

Why size matters

Images that are too small can look blurry when Instagram enlarges them. Images that are too large get compressed by Instagram. Using the right dimensions from the start (e.g. 1080px on the longest side) keeps your photos crisp. Our free resize image and crop image tools run in your browser so you can prepare photos without uploading to any server.

Tips

Shoot or export at least 1080px on the longest side, then downscale to 1080 for the side you need. Use JPG for photos. Avoid over-compressing before upload so Instagram has enough quality to work with.
