Quick answer: RedNote, the English version of Xiaohongshu, uses a 3:4 portrait image at 1080 × 1440 pixels as its standard feed post. A post can contain up to nine images.

That 3:4 ratio is specific to RedNote and Xiaohongshu; it doesn't match Instagram (4:5), Pinterest (2:3), or Stories (9:16).

How the feed works

RedNote is a two-column grid. Each image is a 3:4 card, and the cover (the first image) is the only thing anyone sees before tapping. The cover needs to do two things: be legible at a small grid size and make the content category obvious.

The platform is a lifestyle and recommendation network with a strong "real experience, useful notes" culture. Users save and share posts the way people use Pinterest, and they read the caption as a structured note rather than a tagline.

Design rules for the 3:4 frame

  • Headline at the top. The grid thumbnail is small; the headline needs to be readable at 180 px wide, so large, short, high-contrast text.
  • One topic per post. Multi-image posts read as a mini-guide: cover → steps → results → call to action.
  • Use the 9-image budget deliberately. A how-to post can use 6–9 images; an announcement can use 3.
  • Clean, realistic visuals. Over-styled marketing imagery performs worse than honest, useful-looking content on this platform.

Caption rules

RedNote captions are capped around 1,000 characters and are written in a personal, practical voice. Numbered lists of practical tips do well, and so do plain-language notes about what worked and what didn't. The product is introduced softly; hard-sell language is common to see but rarely performs.

How launch assets fit in

For a product launch, RedNote's 3:4 format can be generated alongside the other formats rather than designed separately. It's in the format set of Neatico's Product Launch Kit, which composes the same launch content for RedNote, Instagram, Pinterest, X, and LinkedIn. The complete format list is in the 2026 social media image sizes table.

Frequently asked questions

What is the RedNote post size? 1080 × 1440 pixels in a 3:4 ratio, with up to nine images per post.

Is RedNote the same as Xiaohongshu? RedNote is the English version of Xiaohongshu, and the image dimensions are the same.

Can I use Instagram images on RedNote? The 1080 × 1350 (4:5) Instagram portrait uploads, but it underfills the 3:4 frame. Rebuild at 1080 × 1440.

Which image is the thumbnail? The first image. Design it as a cover, even if the rest of the post is a guide.

How many images should a launch post use? A complete mini-guide of 6–9 images is the native style. Keep the cover, the setup, the steps, the result, and the close.

If RedNote is one of your launch platforms, build the cover first at 1080 × 1440 and make sure the headline is still readable in the two-column grid.
