About the Threads post image size
Threads uses the same image ratios as Instagram, so 1080 by 1350 portrait (4:5) is the size that fills the most feed space, with 1080 by 1080 square and 1080 by 566 landscape also supported. Since Threads and Instagram share an account and a design language, you can reuse the exact same exports across both. Upload at 1080 pixels wide so text stays legible, and lead with portrait if you only make one size.
Quick tips
- 01Portrait 1080 by 1350 (4:5) fills the most feed space, same as Instagram.
- 02Square and landscape work too; reuse your Instagram exports.
- 03Upload at 1080px wide so any in-image text stays crisp.
