Frequently Asked Questions
Everything creators, managers, and photographers need to know about Instagram photo dimensions and feed layout behavior.
What is the best Instagram aspect ratio?
The best Instagram aspect ratio is 4:5 (1080 × 1350 px) for feed posts. Since most users browse on mobile devices, a 4:5 portrait post occupies the maximum vertical screen space, making it much more engaging than a square (1:1) or landscape (1.91:1) image. For Stories and Reels, the optimal aspect ratio is 9:16 (1080 × 1920 px).
What size should Instagram posts be?
The ideal size for Instagram posts depends on the layout format: 1080 × 1080 pixels for square posts (1:1 aspect ratio), 1080 × 1350 pixels for portrait posts (4:5 aspect ratio), and 1080 × 566 pixels for landscape posts (1.91:1 aspect ratio). Providing a width of at least 1080 pixels ensures that your images look sharp on all screen sizes.
What is the Instagram Reel aspect ratio?
Instagram Reels use an aspect ratio of 9:16, which translates to the recommended resolution of 1080 × 1920 pixels. This full-screen vertical size is also shared by Instagram Stories, TikTok videos, and YouTube Shorts. Keep key elements (like text and faces) within the center 4:5 area so they don't get cut off in standard feed layouts.
What aspect ratios does Instagram support?
Instagram officially supports four main aspect ratios: 1:1 (Square) for feed posts and profile icons, 4:5 (Portrait) for feed posts, 1.91:1 (Landscape) for feed posts, and 9:16 (Vertical) for Stories, Reels, and Live streams. Any images outside of these aspect ratios will be automatically cropped by Instagram when uploading.
Can I upload landscape photos to Instagram?
Yes, you can upload landscape photos to Instagram. The official supported landscape aspect ratio is 1.91:1 (1080 × 566 pixels). However, if your landscape photo is wider (e.g. 16:9 or 21:9), Instagram will crop the sides to fit 1.91:1. To prevent this, you can use our 'No Crop' resizer tools to add top and bottom borders and fit the full landscape shot inside a 4:5 or 1:1 canvas.
