Instagram Post Size
Common Instagram dimensions: 1080x1080 (square), 1080x1350 (portrait), and 1080x1920 (stories).
Choosing the right Instagram format
Creators searching for Instagram post size usually need immediate format confirmation before export. The best starting point for feed reach is often 1080 x 1350 (4:5), because it uses more vertical screen space than square posts while still fitting feed behavior. Square 1080 x 1080 remains useful for product grids and template consistency. Stories and reels rely on 1080 x 1920 in a 9:16 ratio. Correct dimensions reduce blur and prevent accidental crop loss around captions and visual focal points. For stronger outcomes, design with safe margins around text and keep critical details near center.
