What size should an Instagram post be?

The best Instagram post size is 1080 × 1350 pixels for a portrait 4:5 post. It fills more of the feed than a square image while staying inside Instagram’s normal feed crop.

What are the Instagram post dimensions?

Use 1080 × 1350 for portrait, 1080 × 1080 for square and 1080 × 566 for landscape. Those dimensions map to the common 4:5, 1:1 and 1.91:1 Instagram aspect ratios.

What is the Instagram post size ratio?

Instagram feed posts work best at 4:5 for portrait, 1:1 for square and 1.91:1 for landscape. A carousel should keep every slide at the same ratio so Instagram does not crop later slides unexpectedly.

Should Instagram posts be square or portrait?

Use portrait 4:5 when reach matters because it takes more vertical space in the feed. Use square 1:1 when the asset needs to work cleanly in carousels, grids and reused creative.

What is the new Instagram post size?

The current practical default is still 1080 px wide. The newer habit is using portrait 4:5 more often than square because it gives you a taller feed canvas without becoming a full-screen Story or Reel.
