Instagram Image Size Guide 2026
Complete Instagram image dimensions for posts, Stories, Reels, and profile photos in 2026. Resize photos to the correct pixel sizes for sharp, professional uploads.
Why image size matters on Instagram
Instagram is a visual platform, and image quality directly affects engagement. A blurry, cropped, or poorly sized photo gets scrolled past. A sharp, correctly proportioned image stops the scroll.
The challenge is that Instagram applies its own compression to every upload. If you send a 4000-pixel-wide photo or a tiny 500-pixel image, Instagram resizes and recompresses it — often with visible quality loss. Uploading at the recommended dimensions gives Instagram less work to do and produces sharper results on followers' feeds.
This guide covers the exact pixel sizes for every Instagram content type in 2026.
Instagram post dimensions
| Content type | Aspect ratio | Recommended size |
|---|---|---|
| Square post | 1:1 | 1080 × 1080 px |
| Portrait post | 4:5 | 1080 × 1350 px |
| Landscape post | 1.91:1 | 1080 × 566 px |
| Carousel slide | Match post type | Same as above |
Portrait posts (4:5) take up the most screen space in the feed and tend to get higher engagement. Square posts are the classic Instagram format. Landscape works for wide scenic shots but appears smaller in the feed.
Instagram Stories and Reels
Stories, Reels, and full-screen vertical content all use the same dimensions:
- Size: 1080 × 1920 pixels
- Aspect ratio: 9:16
- Safe zone: Keep important text and faces within the center 1080 × 1420 area to avoid UI overlays
If your photo was taken in landscape or square orientation, resize and crop it to 9:16 before uploading. Otherwise Instagram crops automatically — often cutting off heads, logos, or text you placed near the edges.
Profile photo and other sizes
- Profile picture: 320 × 320 px (displays at 110 × 110). Upload at least 320px for a sharp circle crop.
- Instagram ads: 1080 × 1080 px for square, 1080 × 1350 px for portrait.
- Thumbnails: Instagram generates these automatically. Focus on the main upload size.

Resize for InstagramFile format and compression tips
Instagram accepts JPG and PNG. For photographs, JPG at 85–90% quality is ideal — sharp enough for the feed, small enough to upload quickly. Avoid PNG for photos unless you need transparency; PNG files are much larger and Instagram converts them anyway.
Before uploading:
- Resize to exact dimensions — Do not rely on Instagram to crop for you.
- Compress moderately — Files under 1 MB upload faster. Use our JPG compressor if needed.
- Keep originals — Save the full-resolution version on your device. Instagram compression is one-way.
- Check on mobile — Preview how the crop looks on a phone screen before posting.
Common Instagram sizing mistakes
- Uploading oversized images — A 4000px photo gets downscaled aggressively. Resize to 1080px wide first.
- Wrong aspect ratio — Landscape photos in a portrait feed slot get cropped unpredictably.
- Heavy filters before resize — Apply edits after resizing to avoid amplifying compression artifacts.
- Text near edges — Story UI elements cover the top and bottom. Keep text in the safe zone.

Frequently Asked Questions
What is the best size for Instagram posts in 2026?
Square posts work best at 1080×1080 pixels. Portrait posts should be 1080×1350 pixels (4:5 ratio). Landscape posts use 1080×566 pixels. Instagram compresses larger uploads, so uploading at these exact sizes gives the sharpest results.
What size should Instagram Stories be?
Instagram Stories and Reels use a 9:16 aspect ratio at 1080×1920 pixels. This fills the full phone screen without cropping or letterboxing.
What file format does Instagram accept?
Instagram accepts JPG and PNG uploads. JPG is recommended for photographs because it produces smaller files. PNG is better for graphics with text or transparency.
Why do my Instagram photos look blurry?
Blurry uploads usually mean the image was too small, heavily compressed, or the wrong aspect ratio. Upload at the recommended pixel dimensions and avoid over-compressing before upload.
