The optimal Threads image post size is 1080×1350 px (4:5 portrait ratio). This format takes up the most vertical screen space in users' feeds, maximizing engagement. Threads also supports square (1:1) and landscape formats.
Threads profile photos are 320×320 px. By default, Threads syncs your profile picture from Instagram. If you want a different photo on Threads, you can update it separately in the app settings. The photo is displayed as a circle.
Threads carousel images work best at 1080×1080 px (1:1 square). You can include up to 10 images in a carousel. All images in a carousel should use the same aspect ratio for a consistent look as users swipe through them.
Yes, Threads compresses images on upload, similar to Instagram. Uploading at exactly 1080 px wide with high-quality JPEG compression (90%+) gives the best result after Threads' own encoding. Avoid uploading images much larger than 1080 px wide.
