Frequently Asked Questions
What size should Facebook post images be?
1200×630px for link share images and standard posts. This matches Facebook's recommended aspect ratio and displays without cropping on both desktop and mobile.
What is the Facebook cover photo size?
820×312px is the recommended Facebook cover photo size. Keep text and key elements in the center 640px to avoid mobile cropping.
What size should Facebook ad images be?
1080×1080px (1:1 square) works for most ad placements including Feed, Marketplace, and Stories. Facebook recommends keeping text to under 20% of the image area.
Why do Facebook images look low quality?
Facebook re-compresses all uploaded images. Pre-optimizing to exact dimensions at high quality (85%+ JPG) minimizes the impact of Facebook's compression. Avoid PNG for photos — Facebook's PNG→JPG conversion is aggressive.
Can I resize images for Facebook Marketplace?
Yes — Marketplace images display best at 1200×1200px (square). Upload square images to avoid awkward automatic cropping.
