Instagram post size: 1080 × 1350 (4:5)
Use 1080 × 1350 pixels, a 4:5 portrait. It is the tallest shape the feed shows in full, so your post takes up more of the screen than a square - and Cutlin's Portrait 4:5 size, tagged Instagram post, comes back at exactly this size.

Why 4:5 and not square
A square post is 1:1. A 4:5 portrait post is the same width but 25% taller, so it fills more of the screen as people scroll - more room for your product, your words and your logo.
The profile grid crop
On your profile, Instagram shows each post as a tile cut from its middle. A logo in a corner or a headline near the edge of a 4:5 post can disappear from that tile, which is why the safe area matters.
What is the best size for an Instagram post?
1080 × 1350 pixels, a 4:5 portrait. It shows larger in the feed than a square post.
Will a 4:5 post be cropped on my profile?
The profile grid shows the middle of the post. Keep anything important 13% from the sides and 12% from the top and bottom and it stays visible.
A brand used in Cutlin is kept in Melon Cut Guidelines: its guidelines page is at meloncut.com/yourbrand, and Cutlin reads it from there.
