Square Foot

Filter Rightmove and OnTheMarket list and map results by floor area, with local floorplan text recognition.

Square Foot adds floor-area filtering to Rightmove and OnTheMarket residential for-sale searches, in both list and map views. Set your minimum and maximum square footage using a slider or exact values. Square Foot checks advertised size fields, property descriptions and, where needed, floorplan text using OCR that runs locally in your browser. Features: - Filter loaded property cards and map pins by square footage. - Keep unknown sizes visible or choose to hide them. - See checking progress and where each measurement came from. - Move, collapse or close the filter panel. - Close to stop checking and restore the original results; reopen using the extension’s toolbar icon. Only properties already loaded by the website are filtered. Advertised totals may include garages or outbuildings, and OCR can make mistakes. Always confirm important measurements with the agent and original floorplan. Preferences and recent size results are stored locally. The extension makes direct requests to the supported property sites and their image hosts. There are no developer-operated servers, analytics, advertising or cloud OCR services. Square Foot is an independent extension and is not affiliated with or endorsed by Rightmove or OnTheMarket.
