Questions
What size should an Instagram post be?
For the biggest post in the feed, use portrait: 1080 × 1350 pixels (4:5). A square post is 1080 × 1080. Both are 1080 pixels wide, which is the width Instagram shows.
What size is an Instagram Story or Reel?
1080 × 1920 pixels, a 9:16 frame that fills a phone screen. Keep text and faces away from the very top and bottom, where Instagram puts its own buttons.
Will my photo get cropped?
Instagram crops anything outside its frame. Six-IR lets you choose first: Fill crops to the exact frame (smart crop keeps faces in), Fit keeps the whole photo and fills the edges with a blurred or plain background.
