Xiaohongshu cover size: a 3:4 canvas, title safe area, and content layout

A Xiaohongshu cover has one primary job: before someone opens a post, it should make the topic feel worth their attention. It is not an article’s first paragraph squeezed into a vertical image, and it is not a pretty background with a vague line of text.

For content-led creators, start with a 3:4, 1080 × 1440 creator canvas, then check the destination platform’s current display requirements before publishing. Compared with a square image, this canvas gives you room for a topic, a hook, and a little context while keeping the rest of a carousel visually consistent. Platform requirements can change, so always make the final upload decision from the current rules.

A cover and a content carousel do different jobs

A cover answers one question: why should someone keep reading? It can carry a topic, conclusion, contrast, number, or clear subject. It does not need to hold every condition, example, and step from the article.

When the source is a framework, case review, or reading note, the actual information belongs in a knowledge image or later carousel pages. Forcing all of it into the cover either makes type too small or leaves readers unsure of the point after they have already seen the image.

Use a simple test: if a reader sees only the cover, can they describe the topic? If yes, let the next image explain proof and process. If not, rewrite the title before adding more copy.

How to protect a 3:4 title safe area

A safe area is not a mandatory platform requirement. It is a layout habit that avoids crop risk, interface overlap, and visual crowding. On a 1080 × 1440 vertical canvas, begin by leaving about 8% breathing room on every side; do not place the most important title, number, or face against an edge.

Keep a title to one or two clear line groups. If it is too long, do not solve the problem by shrinking the type. Instead:

• Put the outcome on line one and the subject or condition on line two.
• Remove modifiers that do not change the meaning.
• Use a subtitle for context instead of asking the headline to carry everything.
• If the title itself needs explanation, create a carousel rather than turning a cover into a body page.

Use the social image size and safe-area tool to inspect a 3:4 canvas first. If you already have an image to adapt, use the local image resizer.

Three common mistakes in a content cover

The first is making every word the same size, leaving readers with no entry point. The second is using only an abstract phrase such as “growth”, “review”, or “AI”; it creates an atmosphere but does not say what readers will receive. The third is putting a subject too close to an edge, which can feel crowded or become fragile when displayed on a phone.

A steadier sequence is: write a title that makes sense alone, decide whether a person, object, or simple structure helps, and only then choose texture, photo, illustration, or AI visual. The visual should strengthen the title, not replace it.

Should one article have only one cover?

Not necessarily. A short opinion, announcement, or personal-brand introduction can work as one cover. A longer article, tutorial, or case is usually better as one cover plus 3–7 connected content images. The number should follow the relationships in the information, not an attempt to make something merely look like a carousel.

If you are not sure how many images an article needs, make a local estimate with the carousel page calculator, then choose a one-image summary or a carousel in the CarouselMint studio.
