How to estimate lot area
- Pick the unit on the deed sketch or tape: feet, yards, or meters.
- Enter one rectangle, or list several rectangles as length and width per line.
- Read acres and hectares as well as square feet and square meters.
- Hire a surveyor for a legal area. This page is not GIS and not a plat.
Lot area
Sum of rectangles, not a legal survey
| Rectangle | length × width |
|---|---|
| Acres | m² / 4046.8564224 |
| Hectares | m² / 10,000 |
| Legal area | Requires a surveyor |
| Not GIS | No shapefile, bearing, or curve |
| Note row | The engine states a surveyor is required |
How lot rectangles convert to acres
The same meter product as floor area, then acres and hectares. A note row reminds you that a surveyor is required for a legal area. Curves and gores are not modeled.
Acre, hectare, and plat
An acre and a hectare are land units. A plat is a recorded drawing. This page does not read a GIS layer. Interior floor takeoff is square footage. Unit conversion only: sqft to sqm. Generic area units: area converter.
Not a survey and not GIS
Boundaries, easements, and flood lines live on official maps. Typing 150 by 80 ft does not replace a field crew. Estimate only, not code approval for a setback.
Use cases
A back-of-envelope lot, comparing a rectangular pasture to acres, or summing two fenced rectangles. Metes and bounds need a surveyor.
Limits
Positive lengths only. The legal area is not this output. CZNull does not receive the numbers.
