Mercari Listing Image Size Checker

Getting your listing photos right on Mercari is one of the most important factors for making a sale. Mercari recommends images of 1080×1080 pixels in a square (1:1) format, though the platform accepts images as small as 640×640 pixels. Uploading at the recommended size ensures your photos look sharp on all devices, from phone screens to desktop browsers, and prevents any quality loss from automatic resizing.

Dimensions, Format & File Size

Mercari accepts JPEG and PNG image formats with a maximum file size of 10 MB per image. JPEG is the best choice for standard product photography because it keeps file sizes small while retaining good visual quality. PNG works well when you need transparency or have images that include text overlays or graphic elements. Each Mercari listing allows up to 12 photos, so take full advantage of every slot to showcase your item from multiple angles.

Background & Composition Tips

Mercari recommends a clean, uncluttered background for all listings. A plain white or light-colored surface helps your item stand out and gives your listing a more professional appearance. Avoid shooting on busy patterns, rumpled fabric, or dirty surfaces. Natural lighting works best—position your item near a window for soft, even illumination that shows true colors without harsh shadows. If you are photographing small items like jewelry or electronics, consider using a simple lightbox or a sheet of white poster board for a seamless look.

Clothing Photography Tips for Mercari Sellers

Clothing is one of the best-selling categories on Mercari, and great photos are essential for moving inventory quickly. Flat lay photography—laying garments neatly on a clean, flat surface—is the most popular and effective approach for most sellers. Smooth out wrinkles, fold sleeves symmetrically, and arrange the item so buyers can see the full silhouette. For structured items like jackets or blazers, hanging them on a neutral-colored hanger against a plain wall can showcase the shape and fit better than a flat lay.

Include close-up shots of fabric texture, brand labels, care tags, zippers, and any notable details. If there are flaws such as stains, pilling, or loose threads, always photograph them honestly. Mercari buyers appreciate transparency, and disclosing imperfections up front reduces returns and builds your seller reputation. Use all 12 photo slots: a front view, back view, detail shots, label close-ups, and a size tag photo will give buyers the confidence to purchase without asking questions first.
