Short answer: Facebook's Marketplace help page doesn't list a minimum size, file type or photo count, so I won't invent one. It does say you add photos or video when you create a listing, that Facebook may pick a cover photo based on photo or video quality and listing accuracy, and that it may enhance your photos to improve quality (Facebook Help Center).
I've photographed more than 2,500 homes over almost 20 years. Marketplace is a scroll-fast feed, so the first photo has to read at thumbnail size. That's what I'd shoot for.
What Facebook says about Marketplace photos
| Spec | What the platform says | Source |
|---|---|---|
| Adding photos | Choose Add photos to upload from your device (computer) or phone or camera in the app; you can add video too | Facebook Help Center |
| Cover photo | Facebook may select a cover photo based on photo or video quality and listing accuracy | Facebook Help Center |
| Enhancement | Facebook may enhance your listing photos and videos to improve their quality | Facebook Help Center |
| Rules | All listings must follow Facebook's Commerce Policies | Facebook Help Center |
| Size, file type, count | Not stated on this page, so not given here |
That help page walks through the Item for sale flow. Facebook's separate property listing type isn't covered on it, so check your listing form for any extra fields.
How to shoot for a feed of thumbnails
- Lead with the strongest room or the exterior, since Facebook may choose the cover based on quality and accuracy, and a sharp, well-lit, accurate first photo gives it the best option.
- Shoot horizontal and keep subjects near the center, because feeds crop thumbnails.
- Light first. Open blinds, turn on lamps, no flash.
- Hold the phone level so walls don't lean.
- Show every room, kitchen and bathroom included.
- Be accurate. Facebook ties cover choice to listing accuracy, and renters notice mismatches.

Every spec on this page comes from the platform's own help and resource pages, checked on the date at the top. Platforms change these without notice, so if an upload fails, check the page itself.
If you shoot on an iPhone, my app Listing Camera handles the editing step: you take the photo and it fixes light, color and exposure and helps correct vertical lines in the background, about 30 to 40 seconds per photo. It doesn't stage, add or remove anything in the room. One thing to know: every exterior comes back with a sunny blue sky. It's free to try on the App Store with 3 enhancements.
