Official Realtor.com photo specs (Move Inc., 2026)
Realtor.com photo requirements sit on top of each originating MLS's spec, but Move Inc.'s own portal floor is documented: minimum 640x480 pixels, recommended 1024x768 or higher, and a 36-photo cap per listing. Accepted formats are JPG, PNG, TIF, and GIF at the MLS layer; Realtor.com re-encodes to JPG for display. File size tolerated up to 10 MB per image, with a practical sweet spot of 2 to 5 MB. Tile crops are 4:3 landscape, so a landscape-native hero exterior beats a vertical phone shot every time. Because Realtor.com is MLS-fed — not an agent-upload portal — changes you make inside your MLS propagate to Realtor.com within 24 to 48 hours, not instantly.
