The Poshmark Listing Photo size (1000×1000px)
Poshmark is built around square photos, so 1000x1000 pixels is the natural fit for listing your closet. Every cover shot, feed thumbnail, and share appears as a 1:1 square, and designing at exactly this ratio means Poshmark does not crop your garment awkwardly when it renders the cover image that shoppers tap on in search and in their feed.
Fashion resale lives on flattering, clear photos, and 1000x1000 keeps a well-lit shot sharp on the mobile app where nearly all Poshmark activity happens. The cover photo is your storefront: a bright, centered image of the item, ideally styled or on a hanger against a clean background, reads far better in the fast-moving feed than a dim or distant snapshot. Because the cover is square, keep the garment centered so nothing important gets trimmed in the thumbnail crop.
Poshmark lets you add multiple photos per listing for the label, fabric content, measurements, and any wear, all details that reduce returns and build buyer confidence, and keeping them at a uniform 1000x1000 makes your closet look curated and professional. This size uploads quickly over cellular data while still looking crisp when a buyer zooms in. Everything here resizes 100% in your browser with no upload and for free, so your photos stay on your device. Poshmark occasionally updates how images display, so verify the current spec before a big closet refresh.
