Resize Instagram Carousel
Carousel posts get higher engagement than single images because users swipe through multiple slides. Each interaction signals interest to the algorithm. All slides must use the same dimensions, either 1080x1080 square or 1080x1350 portrait. Mix dimensions and Instagram forces everything to match the first slide, cropping the rest unpredictably.

Carousels Outperform Single Images
Data shows carousel posts consistently get higher engagement than single images. Every swipe counts as interaction, signaling to Instagram that your content is worth showing to more people. The more slides users view, the better your post performs. Use all 10 slides when you have the content to fill them.
Keep Dimensions Consistent
Your first slide determines the aspect ratio for the entire carousel. Upload a square image first and all following slides get cropped to square. Upload portrait first and everything becomes portrait. Plan your carousel dimensions before you start. Mixing aspect ratios creates awkward crops and ruins the visual flow.
Tell Stories Across Slides
Carousels excel at tutorials, before-and-afters, product showcases, and educational content. Each slide builds on the last, keeping viewers engaged through the entire sequence. End with a call to action on your final slide. The swipe-through format naturally leads users toward taking action.
