Guides
Calculate land acreage straight from a parcel's plan dimensions — no separate step to work out the area first. Pick a shape (rectangle, triangle or circle), enter its measurements in feet or meters, and get the area in acres, hectares, square feet and square meters all at once.
Supported shapes
- Rectangle — length x width. Covers most residential lots and fields.
- Triangle — base x height, halved. Useful for irregular or subdivided parcels bounded by a straight diagonal edge.
- Circle — from the radius. Useful for center-pivot irrigation fields, roundabouts, and circular easements.
How to use it
- Choose the shape that matches your parcel.
- Choose feet or meters as your input unit.
- Enter the dimensions.
The calculator converts internally to square meters, then reports the area in all four common units side by side so you don't need to look up a conversion factor separately.
All calculations run in your browser — nothing is uploaded.
How many square feet are in an acre?
An acre is exactly 43,560 square feet (4,046.8564224 square meters). A rectangular acre is often visualized as roughly 209 feet by 209 feet, though any shape with that area counts as one acre.
What if my land isn't a simple rectangle, triangle or circle?
Split the parcel into rectangles, triangles or circular sections, calculate each separately, and add the acreages together. For an arbitrary polygon with known corner coordinates, use a dedicated polygon-area tool instead.
