Instagram Carousel Sizes and Aspect Ratios
Choose consistent Instagram carousel dimensions and avoid cropping, tiny text, and mismatched slide layouts.
Use one consistent aspect ratio across an Instagram carousel. Portrait 4:5 is a common choice for feed space, while square 1:1 remains versatile. Design with generous margins and preview the complete sequence before publishing.
Choose the ratio for the content
Portrait layouts give educational slides more vertical room. Square layouts can be easier to reuse across channels. The right choice is the one you can apply consistently without squeezing the copy.
Do not change ratios midway through a deck. Build one canvas system and test the first and densest slides at actual phone size.
Use a safe content area
Keep headlines, page numbers, logos, and calls to action away from the outer edge. A generous internal margin improves readability and gives the design room to survive interface previews and repurposing.
Export quality checks
Export all pages at the same pixel dimensions and in the intended order. Inspect images for compression artifacts and verify that fine lines, small icons, and light-weight text remain visible.
Design the sequence, not isolated posters
A visually consistent deck uses recurring type styles, spacing, color roles, and navigation cues. Variation should signal a change in meaning—an example, quote, or checklist—not a random new template.
