Calculate plot area from four sides (North, South, East, West) in Marla, Kanal, and Acres.
A plot area calculator estimates the total area of an irregular four-sided plot of land when you know the length of each of its four sides — typically labeled by compass direction (North, South, East, West). This is exactly the situation most Pakistani and South Asian property owners face: land-registry documents (Intiqaal, Fard Malkiat) list the four side lengths of a plot but rarely list the area directly. The tool is invaluable for homebuyers verifying a plot's claimed size, sellers preparing accurate listings, real-estate agents comparing properties, Patwari record verification, and property inheritance divisions where exact area determines each heir's share.
Formula
Approximate Area = ((North + South) ÷ 2) × ((East + West) ÷ 2) — the surveyor's averaging method.Most Pakistani plots are not perfect rectangles, and the moment you open the registry document (Fard or Intiqaal) you discover four side lengths that absolutely do not match — north 47 feet 4 inches, south 52 feet 7 inches, east 60 feet, west 58 feet 10 inches. The Patwari did not lie; the corners just are not 90 degrees, which is normal for any plot that was carved out of farmland decades ago or sits on a slight curve in the lane. The painful part is that four side lengths alone do not give you a single exact area — geometrically, the same four sides can flex into different quadrilateral shapes. So the standard surveyor's trick used across Pakistan is the averaging method: average the two opposite sides for length, average the other two for width, multiply like a rectangle. This calculator does that automatically and converts the result to square feet, square meters, Marla (with the size you pick — 272, 250, or 225 sq ft), Kanal, and acres. Honest take: for buying a plot, do this conversion before you visit, before you pay token money, and before you trust the dealer's number. If your calculated area is more than 5 percent off the listed area, walk into the Patwari office and demand a fresh demarcation — it is the cheapest insurance you will buy that month.

When only the four side lengths of a plot are known, there is no unique mathematical area — the same four sides can form infinitely many quadrilateral shapes, each with a slightly different area. The practical convention used by Pakistani Patwaris and property surveyors for approximately-rectangular plots is the averaging method: treat opposite sides as a matched pair, average them, and multiply the two averages like a rectangle. This gives an accurate area for plots that are 'mostly rectangular' (most urban residential plots). For highly irregular plots where opposite sides differ by more than 15%, the tool shows a warning because the approximation error grows — in those cases a surveyor should measure one diagonal and apply the triangulation method for legal precision.

| Plot Size | Square Feet | Square Meters | Square Yards | Kanal |
|---|---|---|---|---|
| 3 Marla | 816 | 75.81 | 90.67 | 0.15 |
| 5 Marla | 1,360 | 126.34 | 151.11 | 0.25 |
| 7 Marla | 1,904 | 176.88 | 211.56 | 0.35 |
| 8 Marla | 2,176 | 202.15 | 241.78 | 0.4 |
| 10 Marla | 2,720 | 252.69 | 302.22 | 0.5 |
| 14 Marla | 3,808 | 353.77 | 423.11 | 0.7 |
| 15 Marla | 4,080 | 379.04 | 453.33 | 0.75 |
| 1 Kanal (20 Marla) | 5,440 | 505.39 | 604.44 | 1 |
| 2 Kanal | 10,880 | 1,010.78 | 1,208.89 | 2 |
| 4 Kanal | 21,760 | 2,021.57 | 2,417.78 | 4 |
| 1 Acre (8 Kanal) | 43,560 | 4,046.86 | 4,840.00 | 8 |
5 Marla (1,360 sq ft) is the entry-level Pakistani plot — perfect for a 3-bedroom single-story family home.
10 Marla (2,720 sq ft) fits a spacious 4-bedroom double-story home with a small lawn and parking for two cars.
1 Kanal (5,440 sq ft) is the upper-middle-class luxury standard — lawn, separate servant's quarters, covered parking.
A 4-sided irregular plot averaging 40 × 68 ft ≈ 10 Marla — use the calculator above for exact irregular measurements.
A plot with sides 67, 42, 60, 72 ft gives an average length of 63.5 ft, average width of 57 ft, and area ≈ 3,619.5 sq ft — roughly 13.31 Marla (standard 272 sq ft system).
A 60 × 90 ft plot (equal opposite sides) is 5,400 sq ft — just under 1 Kanal (5,440 sq ft) in the 272 sq ft Marla system.
A 30 × 60 ft plot is 1,800 sq ft, or about 6.62 Marla — a typical 5-7 Marla residential plot in a Pakistani housing society.
A plot with sides 100, 95, 80, 85 ft has avg length 97.5 and avg width 82.5, giving 8,044 sq ft ≈ 29.57 Marla or about 1.48 Kanal.
A 180 × 100 ft plot equals 18,000 sq ft ≈ 66.18 Marla ≈ 3.31 Kanal ≈ 0.413 acres — the size of a luxury urban house.
A commercial corner plot with sides 45, 40, 60, 55 ft averages 42.5 × 57.5 = 2,444 sq ft ≈ 8.99 Marla — common shop-front sizing.
