Instagram carousel ad size
Instagram carousel ads are 4:5 when every card is an image. The moment one card is a video, Meta supports 1:1 only — so a mixed carousel is a square carousel.

What the other guides get wrong
Spec sheets give one ratio for Instagram carousels, usually 1:1. Meta gives two, and which one applies depends on the cards: 4:5 for images throughout, 1:1 as soon as any card is a video. Build a 4:5 set, add one video card, and the whole unit changes shape.
