Instagram Post Size 2026

Updated November 2026

Best size 1080 × 1350 px 4:5 portrait · biggest space in the feed

In 2025 Instagram switched the profile grid from squares to taller 3:4 tiles, and you can now post at 3:4 too. For most posts, 4:5 still takes up the most room in the feed. Just keep important things away from the very top and bottom, since the grid trims a little there.
