What size is a Threads profile picture?

What is the best image size for a Threads post?

Threads supports square (1080×1080), portrait (1080×1350), and landscape (1080×566) post images, matching Instagram's post dimensions.

Are my images uploaded to a server?

No. All processing happens entirely in your browser using the Canvas API. Your images never leave your device.

Does Threads use the same image sizes as Instagram?

Yes — Threads is built on Instagram accounts and uses the same image dimensions for profile pictures and posts.

What is the best image format for Threads posts?

JPG works well for photographs, while PNG is better for graphics and text-heavy images. Threads compresses images on upload, so always start with the highest quality source.

What is the portrait post size for Threads?

Portrait posts on Threads are 1080×1350 pixels (4:5 ratio). This format takes up more vertical space in the feed than a square post, making it a good choice when the image is the main focus.

Why Use This Tool?

Threads, Meta's Twitter alternative, shares its visual foundation with Instagram. The image dimensions are identical, but Threads has its own content cadence — it's more text-first with images as supporting context rather than the main event. That said, correctly sized images still matter for profile quality and post previews.

Tip: Since Threads uses your Instagram account, your profile picture change affects both platforms simultaneously. Make sure your image looks good both as a circle (Threads/Instagram) and at 320×320 square.

Tips for Threads Images

Profile pictures are shared with Instagram — changing your Threads profile picture updates Instagram too, and vice versa.
Portrait posts (1080×1350) take up more vertical space in the Threads feed, similar to Instagram. Use this format when the image is the main focus.
Threads is conversation-first — images often appear as supporting context for text. Clear, simple images with obvious meaning work better than complex graphics.
Keep images bright and high-contrast — Threads renders in both light and dark mode, and images should look good in both.
Like Instagram, Threads applies compression on upload — start with the highest quality source image available.
