Square Footage & Plot Area Calculator
Add up the area of rooms or a whole home from their dimensions, or measure a plot of any common shape, in feet, metres or yards. Get the area in square feet, square metres, square yards (gaj), cents, guntha, acres, hectares and your state's bigha — plus the cost at a rate per square foot.

By room
4 rowsRoom sizes give carpet area (inside the walls). Builders quote built-up area (adds walls, about 10–15 % more) and super built-up area (adds a share of common areas).
Land units like guntha and bigha vary by region — confirm with local land records before a purchase.
How this is calculated
Rectangle = L × W · Circle = π × (d/2)² · Triangle = ½ × base × height · Trapezoid = ½ × (a + b) × h
- 1 sq m
- 10.764 sq ft · 1 sq yd (gaj) = 9 sq ft · 1 cent = 435.6 sq ft
- 1 guntha
- 1,089 sq ft (1/40 acre) · 1 acre = 43,560 sq ft · 1 hectare = 2.471 acres
Measure each room or part as rectangles and add them up — that's how floor area is usually worked out. For a plot, choose its shape. The result is converted into every unit common in India and abroad; since bigha (and sometimes guntha) differs between states, pick the local value.
Assumptions & sources
- Dimensions are measured at right angles; irregular plots should be split into simple shapes.

Common questions
How do I calculate square footage?
Multiply length by width in feet for each room, then add the rooms together. A 12 × 10 ft room is 120 sq ft.
How many square feet is one gaj?
One gaj is one square yard = 9 sq ft. A 200-gaj plot is 1,800 sq ft.
How big is a cent or a guntha?
A cent is 1/100 of an acre (435.6 sq ft); a guntha is 1/40 of an acre (1,089 sq ft in most states).
