Crop Threads for the feed photo or the avatar

Photo posts want a tall 4:5 frame. Your profile photo is a tiny circle beside every reply. Open the matching guide, keep the safe zone clear, then download a sharp crop.

Text-first feed, still two different files

Threads is built around conversation, but images still compete for attention next to captions and quotes. A clean 1080×1350 photo reads better than a stretched cover strip or a landscape OG card.

The avatar is a different job entirely. Corners disappear under a circle mask, and reply threads show the face at a very small size. A group selfie or wide banner forced into the square usually fails.

Instagram feed exports often transfer well at the same 4:5 pixels—still re-check inside Threads. Each guide below includes pixels, a checklist, and an in-browser crop that stays on your device.

Quick picks

Match the task to the guide so you do not export the wrong ratio.

  • Attaching a photo to a Threads post → Feed post at 4:5, not a wide OG card.
  • Only updating the circle beside your name → Profile picture; keep the face inside the guide.
  • Coming from Instagram → Often reusable pixels; still preview inside Threads.
  • Coming from a Facebook cover → Re-crop; that banner ratio does not belong in the feed.

Frequently asked questions

What size should Threads posts be?

1080×1350 (4:5) is the practical photo default. Square 1080×1080 also works when the scene is already square.

What size is a Threads profile picture?

Upload a square—try 640×640. Threads shows it as a circle on the profile and in reply threads.

Can I reuse Instagram post crops?

Often yes for 4:5 feed photos. Confirm framing inside Threads before you rely on the same file everywhere.

Can I crop Threads sizes in the browser?

Yes. Both guides on this hub include an in-browser crop—files stay on your device until you download and upload to Threads yourself.
