Instagram carousel guides
Practical, specific guides on making Instagram carousels that people actually swipe through and save. Every number here is checked against Instagram’s own documentation or a named study — where a figure is disputed or unverifiable, the guide says so rather than repeating a statistic everyone copies from everyone else.
These are written for people who post carousels regularly: creators, solo marketers and small brand accounts. They assume you already know how Instagram works and skip the preamble.
If you would rather not hand-build every deck, Carousel Studio does the research, writing and layout for you and exports slides at the sizes described here. It is a macOS/Windows app that runs on your own machine — $19 once, no subscription.

Frequently asked questions
What size should an Instagram carousel be?
Use 1080 pixels wide. Square is 1080×1080 and portrait is 1080×1350; portrait takes up more vertical space in the feed. Every slide in a carousel is displayed in the aspect ratio set by the first one, so make them all the same shape. See the sizes and specs guide for the full list.
How many slides can an Instagram carousel have?
Instagram allows up to 20 items in a single carousel post. That is the ceiling, not a target — most carousels do better well short of it.
