The resizer includes 1080 x 1440 for vertical 小红书 covers and 1080 x 1080 for square covers. The vertical cover gives more room for title text, product detail, outfit photos, travel scenes, recipes, and tutorial steps. The square cover is useful when the image needs to remain compatible with other social platforms or when the visual subject is naturally centered.
Readable title text 封面文字
小红书封面经常输在文字太小。电脑上看起来精致的标题，在手机信息流里可能完全看不清。A good cover title should be short, high contrast, and placed where it does not fight the main subject. Use fewer words and larger type. If the cover is for a shopping note, beauty tutorial, recipe, or travel guide, let the title explain the benefit quickly. Avoid putting important text directly on a complex background unless you add a clean text block or strong contrast.
Subject placement 主体位置
Keep faces, products, food, outfits, or key screenshots away from the extreme edge. Even if the final export is correct, different previews can crop or mask parts of the image. A product should not touch the border unless that is an intentional close-up. A face should not be cut at the forehead or chin. A tutorial screenshot should leave room for labels. Turn on the safe area overlay and make sure the main story remains inside the central area.
Crop, fit, and blur background
Crop to Fill is best for designed covers with extra space around the subject. Fit with Background is safer for product images, screenshots, and comparison images where every edge matters. Blur Background is useful when the original photo is horizontal or square but you want a polished vertical cover. It fills the canvas without inventing content, while the full source image stays visible in front.
Practical workflow 实用流程
Upload the source image, choose 小红书 竖版封面, and preview the 1080 x 1440 crop. Add or check title text in your design tool first, then use the resizer to verify that the title and subject survive the target ratio. If the image is also needed for Instagram or a shop listing, export a square 1080 x 1080 version too. Before posting, view the cover on your phone and ask one simple question: can a new viewer understand the topic in one second?
Common mistakes 常见问题
Do not make the cover look good only inside the design tool. 小红书 users usually see it as a small card first. If the title is long, thin, or placed on a noisy background, it will lose impact. Avoid putting too many stickers, arrows, numbers, and subtitles on the same cover. The cover should create curiosity, not explain every detail. If the note is about a product, keep the product recognizable. If it is about an experience, keep the scene or result clear.
Before you post 发布前检查
Check the cover in a phone-sized preview. The title should be readable, the main subject should stay inside the safe area, and the color contrast should be strong enough for quick scanning. If the note belongs to a series, keep title placement and visual rhythm consistent across the series. Consistency makes the account easier to recognize. A good 小红书 cover does not need to be complicated; it needs to communicate quickly and survive the crop.
For bilingual or cross-border creators, keep one language as the main visual message and use the second language only when it adds clarity. Too much text in two languages can make the cover feel crowded. For similar vertical cover decisions, compare the TikTok cover guide and the Instagram image size guide.
