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.
