Area Calculator

How to use the Area Calculator

1. Choose a shape: rectangle, square, circle or triangle.
2. Enter the measurements in the same unit.
3. Read the area in sq ft, sq yd, acres, kanal and marla.

Area Calculator example

A plot 60 ft long and 40 ft wide is 2,400 square feet — about 0.055 acres, or roughly 8.8 marla.

Who uses the Area Calculator?

Homeowners, property dealers, builders and students measuring plots, rooms and land.

What Is an Area Calculator?

An area calculator finds the size of a surface — a plot of land, a room, a field — from its measurements. For a rectangle, area is length multiplied by width. For a circle, it is pi times the radius squared. For a triangle, it is half the base times the height. The formulas are simple, but the unit conversions are where people go wrong: one kanal is 20 marla, one acre is 43,560 square feet, and a marla itself has two different values in Pakistan, depending on who is measuring. This tool applies the formulas and shows the answer in every unit at once, so you never have to convert by hand.

How to Calculate Area (Step by Step)

Step 1: Choose a shape. Pick rectangle, square, circle, or triangle — the shape that matches your plot or room.

Step 2: Enter the measurements in the same unit. Measure length and width in feet, and enter both in feet. Mixing feet and metres in one calculation is the most common mistake, so keep one unit for every number you type.

Step 3: Read the area in every unit. The tool shows the result in square feet, square yards, acres, kanal, marla, killa, hectares, and square metres. Pick the unit your buyer, your builder, or your exam expects.

Step 4: Double-check before you decide. Measure twice, especially for land. A plot that is not a perfect rectangle should be split into rectangles and triangles, measured separately, and the areas added together.

Kanal, Marla and Square Feet — Both Marla Standards Explained

In Pakistan, land is usually described in kanal and marla. One kanal equals 20 marla, and one acre equals 8 kanal. The part that confuses people is the marla itself, because there are two standards, and both are genuinely used.

The first is the housing-society standard: in DHA, Bahria Town, and most housing societies, one marla equals 225 square feet. A 5-marla plot in a society is therefore 1,125 square feet, and one kanal is 4,500 square feet. The second is the Punjab revenue standard: in revenue records and official land documents, one marla equals 272.25 square feet. Under that standard, a 5-marla plot is 1,361.25 square feet, and one kanal is 5,445 square feet. The difference is real — about 21% — so a plot described as "5 marla" can mean two different sizes depending on the context.

Before you buy, sell, or quote a price, ask which standard applies. For a plot inside a housing society, expect 225 square feet per marla. For revenue records, mutation papers, or a patwari's measurement, expect 272.25. The calculator shows results in square feet as well as marla, so you can always compare the two: if the square feet match, the marla figure is right under either standard.

Who Uses This Tool?

Property dealers use it to quote plot sizes to buyers in the unit the buyer understands. Homeowners use it to check a plot's size before buying, or a room's size before buying tiles, carpet, or paint. Builders use it to estimate material for a floor or a wall. Farmers use it for fields measured in acres and killa. Students use it for geometry homework — the area of a circle, a triangle, or a rectangle — and for the kanal and marla questions that appear in Pakistani maths and everyday life.

Benefits of This Calculator

The main benefit is accuracy across units: one measurement gives you every unit at once, so a conversion mistake cannot creep in. The second is the marla explanation — the tool does not hide the two standards, it shows them, so you can check a dealer's figure instead of taking it on trust. The third is speed: a plot area that takes five minutes with a phone calculator takes five seconds here. And it is free, with no sign-up, so you can use it on site, on your phone, while standing on the plot itself.

Worked Example

A plot is 60 feet long and 40 feet wide. Multiply: 60 × 40 = 2,400 square feet. That is about 0.055 acres. In marla, the answer depends on the standard. Under the housing-society standard of 225 square feet per marla, 2,400 ÷ 225 = about 10.7 marla. Under the Punjab revenue standard of 272.25 square feet per marla, 2,400 ÷ 272.25 = about 8.8 marla. Same plot, two correct answers in marla — which is exactly why the square-feet figure is the one to agree on first. For a circle, the same idea applies: a round garden with a radius of 10 feet has an area of 3.14 × 10 × 10 = 314 square feet. Measure, multiply, and let the tool handle the units.
