Two reliable methods
Read the parcel card. Every U.S. county publishes acreage on the parcel record. Landy's parcel map surfaces the same number directly from the source. Fastest path, no drawing required.
Draw on the map. Use the land measurement tool to tap the corners of any shape and get distance, perimeter, and area. Handy when you want to measure a sub area like a building pad, a garden, or road frontage.
Step by step
- Open the parcel map and search the address.
- Open the parcel card and note the published acreage and lot dimensions.
- If you need a sub area, switch to the measurement tool and tap the corners. Close the shape to read the area.
- Switch units between acres and square feet to sanity check the result. One acre is 43,560 square feet.
- Save the property if you want to return to the same measurement later.
How accurate is online measurement
County acreage is calculated from the parcel polygon and is usually within a few percent of a survey result. Manual drawing accuracy depends on how cleanly you can see corners on the base map. Newer aerial imagery and clear fence lines help. Tree cover and shadows hurt. Use online measurement to estimate; use a survey to certify.
Common reasons people measure
- Comparing two listings before booking a visit.
- Estimating how much fence or sod a project needs.
- Checking road frontage before a curb cut.
- Sizing a building pad against setback rules.
- Confirming the acreage in a listing matches the county record.
Key takeaways
- Start with the published acreage on the parcel card. It is fast and usually close.
- Use the measurement tool for sub areas like building pads or frontage.
- Online measurement is for estimating; a survey is for certifying.
