What matters
Facebook Marketplace Listing dimensions at a glance
Facebook Marketplace listing images display as 1:1 squares in search results and product grids. A 1200×1200 source gives sharp rendering on all devices while keeping file size manageable.
Marketplace listings compete visually with dozens of other products on screen. A clean, correctly sized product photo stands out and builds buyer trust instantly.
Non-square images get center-cropped in the listing grid, potentially hiding product details or context. Low-resolution photos look unprofessional next to competitors' sharp images.
