FAQ
Frequently asked questions
How do I measure a property online?
Search the address, trace the area you want on the satellite image, and read the square footage. Turn on parcel boundaries first to see where the lot ends — those currently cover U.S. properties only. Divide square feet by 43,560 for acres.
Is it free to measure a property?
Yes — you can measure properties for free every month, with no app to install.
Can I measure more than one area?
Yes. Draw separate areas for the lawn, driveway, patio, pool, or any surface. Each reports its own square footage and they total together.
How accurate are satellite measurements?
Accuracy depends on how carefully you trace the boundary — plenty close for planning and estimates. For legal boundaries, use a survey.
