4:5 is an aspect ratio — these are the pixel sizes people most often export after cropping. See the full 4:5 pixel dimensions table.
| Use | Pixels (W × H) |
|---|---|
| Instagram portrait | 1080 × 1350 |
| Pinterest standard | 1000 × 1250 |
4:5 occupies more vertical feed space than square, so it stops the scroll better — use it for portrait Instagram posts.
Export at 1080×1350 px, Instagram's maximum portrait resolution, for the crispest feed appearance.
Keep the subject slightly above center; the bottom of a 4:5 post sits near the caption and engagement icons.
When cropping a horizontal photo to 4:5 you lose a lot of width — start from a portrait or square source when possible.

4:5 is the tallest aspect ratio Instagram permits in the main feed, displayed at 1080×1350 px. It is the go-to format for portrait feed posts because it occupies the most vertical space without being cropped.
Open the omnikitbolt crop tool, choose the 4:5 ratio, frame your subject, and export at 1080×1350 px. This gives you a full-height portrait post with no auto-cropping by Instagram.
4:5 takes up about 25% more vertical feed space than 1:1 square, which generally improves visibility and engagement. Use 4:5 for portrait-friendly subjects and 1:1 when a square composition looks stronger.
No. 4:5 is within Instagram's allowed range, so a correctly cropped 4:5 image displays in full. Anything taller than 4:5 (like 9:16) gets cropped in the feed, which is why 4:5 is the portrait limit.
Crop to 1:1
The classic square — perfect for Instagram feed posts, profile pictures and avatars, album covers, and product thumbnails that display as a square.
Crop to 9:16
The full-screen vertical standard — perfect for Instagram Reels and Stories, TikTok, YouTube Shorts, and Snapchat (typically 1080×1920 px).
Crop to 2:3
The vertical version of 3:2 — perfect for Pinterest pins (1000×1500 px), portrait photo prints, and posters where height carries the composition.
Crop to 16:9
The widescreen standard — perfect for YouTube thumbnails and videos (1280×720, 1920×1080), presentation slides, desktop wallpapers, and any 16:9 display or player.
