How This Calculator Works
This land area calculator helps you compute the area of land plots in various shapes — rectangle, triangle, circle, and trapezoid — and instantly converts the result into dozens of commonly used land measurement units worldwide, including acres, hectares, square feet, square meters, bigha, marla, kanal, and more.
The formulas are straightforward: rectangle area = length × width, triangle area = ½ × base × height, circle area = π × radius², and trapezoid area = ½ × (base1 + base2) × height. Enter your measurements in your preferred unit (feet, meters, yards), and the calculator handles all conversions automatically using precise conversion factors.
Land measurement units vary significantly by region. In India, bigha, biswa, and ground are common. In Pakistan and parts of North India, marla and kanal are standard. Western countries primarily use acres (US/UK) and hectares (metric system). This calculator bridges all these systems, making it invaluable for real estate transactions, agricultural planning, and construction projects across different regions.
Frequently Asked Questions
How do I calculate the area of an irregular plot of land?
For irregular plots, divide the land into regular shapes (rectangles and triangles), calculate each area separately, and add them together. Alternatively, if you know the coordinates of each corner, you can use the Surveyor formula (Shoelace formula). For complex shapes, a professional land survey using GPS is most accurate.
What is the difference between bigha, marla, and kanal?
These are traditional South Asian land measurement units. A bigha varies by region: in UP/Bihar it is about 2,500-2,700 sq ft, while in Bengal it is about 14,400 sq ft. A marla is 272.25 sq ft (25.29 sq m). A kanal equals 20 marlas or 5,445 sq ft. These vary by state, so always confirm local standards.
How many acres in a hectare?
One hectare equals exactly 2.47105 acres, or 10,000 square meters (100m x 100m). One acre equals 0.404686 hectares, or 43,560 square feet. Hectares are used internationally, while acres are common in the US, UK, and other Commonwealth countries.
How do I measure land area without a survey?
For rough estimates, you can use Google Maps (right-click to measure distance/area), pace off dimensions (one stride ≈ 2.5 feet), or use a measuring wheel. For rectangular plots, multiply length × width. For buying or selling land, always use a licensed surveyor for accurate legal measurements.
