Best Instagram Grid Size Guide for 2026

Getting the right Instagram grid size is essential for a professional-looking profile. If your tiles are misaligned or low resolution, your puzzle feed effect will look amateur. This guide covers the exact dimensions you need for every grid layout.

Square (1:1): 1080 x 1080 px — The standard, most widely used format.
Portrait (4:5): 1080 x 1350 px — Takes up more feed space, higher engagement.
Landscape (1.91:1): 1080 x 566 px — For wide images, but takes less feed space.
Story (9:16): 1080 x 1920 px — Full-screen vertical format.

Grid Size Tips

Always start larger than you need. You can scale down, but you cannot recover lost resolution from a small source.
Use 4:5 portrait for higher engagement. Portrait posts take up more feed space and get more visibility.
Account for Instagram gaps. Instagram adds spacing between posts. Add a 2-5 px gap in your source image design to prevent visual disconnect.
Check on mobile before finalizing. Preview your grid on a phone to ensure alignment. Desktop views do not show the exact mobile layout.
