Instagram Image Sizes 2026: The Complete Guide

Uploading an image with the wrong size on Instagram means blurry photos, unexpected crops, or black bars around your content. This guide gives you every Instagram image size you need for 2026 — feed posts, Stories, Reels, carousels, and profile photos.

Instagram Image Sizes at a Glance

Format	Size (px)	Aspect Ratio	Notes
Feed — Square	1080×1080	1:1	Safe choice for all feeds
Feed — Portrait	1080×1350	4:5	Best feed presence, ~35% more space
Feed — Landscape	1080×566	1.91:1	Wide shots only
Story / Reels	1080×1920	9:16	Safe zone: central 1080×1420 px
Carousel slide	1080×1080	1:1	Square keeps slides consistent
Profile photo	1080×1080	1:1	Displayed as a circle at 110×110 px

Which Format Should You Use for Feed Posts?

Portrait (4:5) is the highest-performing format for static feed posts. It takes up about 35% more vertical space than a square, pushing competitor posts off the screen. Use it for single-image posts whenever your composition allows.

Square (1:1) is the safe default. It works everywhere and looks consistent across carousels. If you're posting a multi-slide carousel, stick to square so all slides match.

Landscape (1.91:1) uses the least feed space. Only use it when your image is naturally wide — panoramas, product flat lays, or group shots.

Stories and Reels: Safe Zones Matter

The correct size for Instagram Stories and Reels is 1080×1920 px (9:16 vertical). But uploading at the right size is not enough.

Instagram overlays UI elements — your profile icon, the reply bar, and swipe-up links — at the top and bottom of the frame. The safe zone for important content (faces, text, logos) is the central 1080×1420 px area. Keep anything important away from the top 250 px and bottom 340 px.

Profile Photos: Upload Bigger Than You Think

Instagram displays your profile photo at just 110×110 px, but you should upload at 1080×1080 px. Here's why: Instagram crops your photo into a circle from the center of the square. A high-resolution upload gives Instagram enough detail to render it sharply on Retina and high-DPI screens.

Frame your subject centrally and leave margin on all sides — anything near the edges gets cut off by the circle crop.

File Format Tips

Instagram converts all uploads to JPEG internally, regardless of what you upload. To minimize quality loss:

Upload as JPG for photographs — starting with JPG gives you more control

Upload as PNG for graphics, logos, or text overlays — PNG's lossless encoding preserves sharp edges better before Instagram's re-encoding

Keep file size under 1 MB before uploading — larger files don't improve quality and can trigger heavier compression

Upload at exactly 1080 px wide — wider uploads get scaled down, smaller uploads get scaled up (and look soft)
