Rednote Image Ratio Guide: When to Use 3:4, 1:1, and 9:16

For Rednote image posts, 3:4 vertical is usually the best starting point. It gives enough room for a clear title, a central subject, and supporting details without feeling cramped on mobile.

3:4 vertical: best default for image posts

Use 3:4 for covers, guides, product recommendations, beauty routines, travel notes, and educational cards. It fills the mobile feed well while keeping the post readable.

1:1 square: clean and compact

Square images work well when the subject is simple: a product shot, a profile-style image, a minimal poster, or a clean visual grid. If the post needs a long title or multiple text blocks, 1:1 can feel tight.

9:16 vertical: stronger full-screen feeling

9:16 is useful for outfit photos, travel scenes, mood boards, and immersive visuals. For multi-page image notes, 3:4 is often easier to read page after page.

Keep multi-page posts consistent

A Rednote post feels more polished when the cover and inner images use the same ratio. You can use the Rednote image generator to create a cover first, then generate matching pages in the same visual style.
