About this tool
The 1080 by 1350 portrait post (4:5) is the tallest feed post Instagram shows without cropping, so it occupies the most screen space as someone scrolls. Photographers and brands use it to make single images and carousels feel bigger without switching to Reels. The tool crops to that 4:5 frame, the largest footprint a feed post can take without Instagram trimming it.
How to use this tool
- Choose a vertical photoPortraits, fashion and product shots work best in the taller 4:5 frame.
- Position the cropDrag so faces and products sit inside the 1080 x 1350 frame, with a little space at the top.
- Upload to the feedDownload and post - the full 4:5 image shows as people scroll.
Getting the most from 4:5
Phone photos are usually 3:4, slightly taller than 4:5, so a small crop is needed - decide whether to lose sky or floor rather than letting the app choose. On the profile grid the post may be shown with a different crop than in the feed, so keep faces and products in the centre third.
