Instagram Image Sizes in 2026: Feed, Reels, Stories & Profiles (Cheat Sheet + Free Resizer)

Post 1080 × 1080 for feed squares, 1080 × 1350 for portrait posts, and 1080 × 1920 for Reels and Stories — that covers 95% of Instagram in 2026. Export at those exact pixels and nothing gets cropped, nothing looks soft after Instagram's compression, and your profile looks intentional instead of accidentally resized.

The Instagram sizes that actually matter in 2026

Feed posts

• Square: 1080 × 1080 px (still the safe default)
• Portrait: 1080 × 1350 px (4:5) — taller posts take up more screen, which is why engagement has shifted this way
• Landscape: 1080 × 566 px

Reels

• 1080 × 1920 px (9:16) for the full-screen reel
• 1080 × 1080 also works, but 9:16 is what the Reels tab shows best
• Cover image: 1080 × 1920 to match the video frame

Stories

• 1080 × 1920 px (9:16)
• Keep text and buttons inside the middle area — the top is covered by the story header and the bottom by the reply bar

Profile

• Profile picture: 320 × 320 px (renders at ~110 px, but upload high-res so it stays sharp)
• Highlights covers: 1080 × 1920, cropped to a circle in the grid

Why exact pixels matter

Instagram compresses images aggressively. Uploading 2000 px does not make the photo sharper — it just gets downscaled, and if the aspect ratio is wrong, Instagram crops it automatically. That is where most people lose the shot: text cut off at the edges, faces cropped in the grid, or a 4:3 photo awkwardly centered with bars.

The fastest Instagram workflow

1. Pick the format: square post (1080 × 1080), portrait (1080 × 1350), landscape (1080 × 566), or story/reel (1080 × 1920).
2. Use a preset instead of typing pixels. Resize images for Instagram applies the exact spec — no manual cropping math.
3. If your source file is WebP (common after Chrome downloads or CMS exports), convert to JPG first: WebP → JPG.

All of this runs locally in your browser at imgsize — your images never get uploaded anywhere, and the 85+ presets cover Instagram, Etsy, Amazon, YouTube, TikTok and more.

TL;DR

Content	Size	Ratio
Feed — square	1080 × 1080	1:1
Feed — portrait	1080 × 1350	4:5
Feed — landscape	1080 × 566	1.91:1
Reels / Stories	1080 × 1920	9:16
Profile picture	320 × 320	1:1
Highlights cover	1080 × 1920 (circular crop)	9:16

Export once at these sizes and every post, reel, and story fits the frame perfectly.
