Xiaohongshu Image Size Guide
Xiaohongshu is strongly vertical in the feed, so the image ratio affects far more than clarity. It changes how attractive the cover feels before anyone opens the post.
Common working ratios
- Square: 1080 × 1080
- Portrait: 1080 × 1350
- Taller portrait: 1242 × 1656
Why 3:4 is popular
It is slightly taller than 4:5, which helps it stand out more in a vertical browsing flow. For covers and image-led post graphics, it often feels more natural.
What to watch on cover images
If the image contains a title, a product, or a person, do not judge it only at full size. The thumbnail impression matters most, so it is worth adjusting the crop yourself to keep the focus in place.
