Xiao Hong Shu (RedNote) cover size and aspect ratios
Which aspect ratios Xiao Hong Shu (RedNote) accepts for image and video notes, the pixel sizes to export, and how the cover is cropped in the two-column feed.
Updated
Quick answer: Export Xiao Hong Shu image notes at 3:4 portrait, 1080 × 1440 px. The app also accepts 1:1 (1080 × 1080) and 4:3 (1080 × 810), but a note shows only one ratio, set by the first image — so keep every image in a note the same shape. A note holds up to 18 images. For video notes, shoot vertical and upload a 3:4 cover.

Why 3:4 wins the feed
Xiao Hong Shu's home feed is a two-column grid of cards. A 3:4 cover is the tallest shape the feed shows, so it takes noticeably more screen space than a square or landscape cover — more room for your image and more chance of a tap. That is why almost every creator guide recommends 3:4 as the default for covers.
The first image sets the shape
All images in a note are shown at the same ratio, and the first image decides which one. If your first image is 3:4 and the third is landscape, the landscape image is filled or cropped to 3:4 in the note viewer. Crop every image to the same ratio before you upload, and put the image that works best as a cover first.
Video notes
Vertical video (9:16 or 3:4) fills the phone and suits the feed; 16:9 is accepted but shows small. The feed card uses the cover, not the video frame, so choose or upload a cover deliberately — a 3:4 image with a clear subject reads best in the two-column grid. Maximum video length varies by account and upload method (figures from 5 to 15 minutes are reported), so check the uploader in your app before you plan a long video.
Design tips for covers
- Keep the subject and any cover text inside the central area — the card is small in a two-column grid.
- Short cover text (a few characters) in large type works better than a paragraph.
- Post original, unwatermarked media. Reposted content needs the creator's permission and credit under the platform's community rules.

Frequently asked questions
What is the best cover size for Xiao Hong Shu?
1080 × 1440 pixels, a 3:4 portrait ratio. It is the tallest shape the two-column feed shows, so the cover gets the most space.
Can I mix portrait and square images in one Xiao Hong Shu note?
You can upload them, but the note displays every image at the ratio of the first one, so the others get filled or cropped. Crop all images to the same ratio first.
How many images can a Xiao Hong Shu note have?
Up to 18 images per image note.
What cover should I use for a Xiao Hong Shu video?
Pick a frame or upload an image, ideally 3:4. The feed card shows the cover, so make it a clear, well-lit image with at most a few words of text.
