Instagram carousel guide
Instagram carousel: size, ratio and slides that match
A carousel post holds up to 20 photos and videos, and the orientation you pick (square, portrait or landscape) applies to all of them. Make every slide the same size, 1080 × 1350 px (4:5) for the most room. Slides that share one background colour read as one set. AwaCut puts every product on the same colour at once, offline.

Cut every product out with AwaCut
Drop the photo, or a whole folder, into AwaCut. Choose Alpha for a transparent PNG, or Custom and type a colour such as #FCE7F3 to get it on a plain background straight away. About 4 seconds a photo on a Mac Studio (M4 Max), at full size.
Make the slides one size
Three to ten 1080 × 1350 canvases, the same colour, the product in the same place on each, a short title at the top and the slide number at the bottom.
Post them together
On a computer: Create, Post, Select from computer, choose up to 20, put them in order, then Next and Share. The orientation you choose applies to all of them.
The finished carousel
Three 1080 × 1350 slides on one pale pink (Custom, #FCE7F3): mug, candle, vase, each cut out by AwaCut, same headline style, numbered.
Check the first slide
Only the first slide shows in the feed and the grid. Make it the one that earns the swipe.

Three mistakes on carousels
Slides of different sizes
Instagram applies one orientation to all; the odd ones get cropped.
Every slide a different background
A set reads as a set when the background repeats.
A weak first slide
It is the only one people see before swiping.
Why one colour sells a set
A carousel of products on one colour looks like a catalogue page. AwaCut cuts out a whole folder at once, so a week of posts is one drop, not one upload per photo. It runs on your computer, with no credits: as many photos as you want, all year.
Try it on your own photos: the first 10 are free, no account.
