Why Threads shares sizing with Instagram
Threads is built by Meta on shared infrastructure with Instagram, which is why its recommended feed dimensions (1080×1350 vertical, 1080×1080 square) match Instagram’s own — a set of images sized for one generally works cleanly for the other.
Sizing images before a bulk import
Sizing media correctly before a bulk import avoids a platform recompressing or cropping it unpredictably after upload — worth checking before scheduling a large batch.
