Instagram Post Size: Portrait, Square & Landscape Guide

Use 1080-pixel-wide working files and choose the aspect ratio that matches the feed composition you intend.

Practical 2026 exports

Current reputable secondary guidance recommends 1080×1350 for a 4:5 portrait, 1080×1080 for square, and 1080×566 for 1.91:1 landscape. These are practical exports, not a promise that every Instagram surface displays them identically.

Carousel and grid considerations

Use one orientation throughout a carousel when possible, keep important content away from crop edges, and preview the current profile grid. Instagram presentation changes, so this page separates current secondary pixel advice from first-party claims.

Export checklist

Use sRGB, start from an adequately sized original, inspect compression after upload, and keep a master file so you can re-export if the grid changes.
