Land Area and Lot Size Calculator for Acres, Hectares, and Square Units

Pick a shape, enter dimensions or boundary points, and get acreage plus conversions and perimeter in seconds.

Use the same unit for every dimension. The calculator returns area (acres and more) plus perimeter/circumference for planning.
Add boundary points in order around the lot (clockwise or counterclockwise). For Latitude/Longitude, results are approximate for planning and work best for small areas.

Tip: If you have a listing in acres but a site plan in meters, convert both to square meters for consistent comparisons, then convert back to acres if needed.
Splits are mathematical planning only. Real subdivisions depend on zoning, setbacks, road access, utilities, easements, and survey rules.
