Instagram post size (square, portrait, landscape)
Use 1080×1080 (1:1) for square, 1080×1350 (4:5) for portrait, and 1080×566 (1.91:1) for landscape posts. Use the resizer as a post size converter.
Which size should I use?
- Portrait (4:5) gets more vertical space on mobile.
- Square (1:1) is a safe default for grids.
- Landscape (1.91:1) works for wide images or link previews.
3 steps (using this tool)
- Choose the post size you need (1:1, 4:5, or 1.91:1).
- Use Crop for full-bleed images or Pad for text-heavy designs.
- Export JPG for photos or PNG for sharp text.
Grid tip
Keep key elements centered so they remain consistent across grid previews and feed crops.

Quick tip: If your source is larger, Instagram will downscale it—avoid upscaling tiny images.
