Land Area Calculator

Because side lengths alone do not fix a shape. Push the corners of a square and it flattens into a diamond — the four sides stay exactly the same, but the area drops. One measurement corner to corner across the middle pins the shape down, and with it the area.

You still get an answer, shown as an estimate with a range. For a plot that is roughly rectangular the estimate is usually close, but the range tells you honestly how much room there is for error.

The number printed along each boundary line is that side's length, almost always in metres. Enter them going round the plot in order and switch the unit to metres. FMB sketches rarely show a diagonal, so expect an estimate unless you measure across the middle yourself.

Every unit is shown at once. One cent is 435.6 square feet and one ground is 2,400 square feet, both standard across Tamil Nadu. Press "show every unit" for acres, hectares, ares and the rest.

Break the curve into several short straight sections and enter each one as a separate side. The shorter the sections, the closer the result. Support for genuine curves is not there yet.

No. This is arithmetic on numbers you typed, and it cannot know where your boundary stones actually sit. Registration, sale and disputes need a licensed surveyor who has measured the land on the ground.

Download the PDF. It has the drawing of your plot with every measurement marked, the area in all units, and a note that this is a calculation rather than a survey — which is worth having in writing if you are showing it to anyone.
