Threads Image Size Guide 2026 (Meta's Threads App)
Recommended Threads image and video dimensions for 2026. Avoid Meta auto-cropping by exporting at the exact aspect ratios with ShareMint.
Threads inherits Instagram's aspect-ratio rules (1:1, 4:5, 9:16) but renders the feed differently, so the same image can look great on Instagram and cropped on Threads. In 2026, portrait 4:5 (1080×1350) gets noticeably more screen real estate in the Threads feed than a 1:1 square, which translates directly into more stopping power and engagement. This guide lists every Threads image size and shows how to pre-crop so Meta's auto-crop never chops off your captions or faces.
| Placement | Size (px) | Notes |
|---|---|---|
| Square post | 1080 × 1080 | 1:1 |
| Portrait post (best) | 1080 × 1350 | 4:5 — max feed real estate |
| Vertical post | 1080 × 1920 | 9:16 full-screen |
| Profile photo | 640 × 640 | 1:1 circle render |
Steps
Know the Threads sizes
Post images: 1080x1080 (square), 1080x1350 (4:5 portrait), or 1080x1920 (9:16 vertical). Profile photo: 640x640. Threads inherits Instagram's aspect rules but renders feed differently.
Choose square or 4:5
4:5 (1080x1350) takes more vertical screen real estate and gets more attention in the feed. Use it for high-priority posts.
Resize in ShareMint
Drop your image into ShareMint, pick the Threads preset, and click on your subject to set a focal point. The crop locks onto that point across ratios.
Avoid Meta auto-cropping
If you upload a wide landscape, Threads center-crops it. Pre-resizing to the exact 4:5 ratio with ShareMint prevents Meta from chopping off captions or faces.
Post from desktop or mobile
Threads accepts uploads from threads.net (desktop) and the mobile app. Desktop is faster when you have already prepared assets in ShareMint.

Does Threads use the same sizes as Instagram?
Mostly yes. Threads accepts the same 1:1, 4:5, and 9:16 ratios. The feed display is different though, so 4:5 portraits often perform best for visibility.
What is the maximum file size on Threads?
Threads accepts images up to about 8MB. WebP and JPEG at 90% quality keep high-resolution shots well within that limit.
Why do my Threads images look soft?
Meta re-encodes uploads. Starting with a sharp 1080-wide source and pre-cropping to the exact aspect ratio in ShareMint minimizes the quality drop.
Can I post a horizontal image?
You can, but Threads will display it letterboxed or cropped into a 1:1 frame in the feed. Vertical 4:5 or 9:16 always wins on engagement.
