Plot Shape & Area Calculator Pakistan
Enter front, back, left, and right measurements to estimate plot area in Marla, Kanal and square feet, see the actual shape drawn live, and understand how rectangular, tapered, or irregular plots affect planning and resale across Multan and Pakistan.
Estimate only. For exact area, use approved drawings, site measurement by a qualified surveyor, or relevant authority (revenue / society / development authority) records. Don’t use this output for legal documents.
How to use this plot shape calculator
- Measure all four sides on site with a steel tape — front, back, left, and right.
- Enter each measurement in the tool, in feet, yards, or meters as you prefer.
- Pick your Marla standard — Punjab official (270 sq ft), housing society (225 sq ft), or KP/historical (272.25 sq ft).
- Read the live shape drawn from your measurements — this catches measurement errors visually.
- Check area in Marla, Kanal, and sq ft, plus the shape classification and build/resale notes.
The area formula behind this tool
This calculator uses the average-side trapezium approximation: it averages the front and back widths, averages the left and right depths, then multiplies the two averages. The formula is:
This works well for plots that taper from front to back (very common in Pakistan) or have slight left/right depth differences. For severely irregular plots with bent sides or unequal angles, the approximation drifts and you should commission a proper surveyor with theodolite or total station measurement.
Common plot shapes in Pakistan
| Shape | What it looks like | Implications |
|---|---|---|
| Rectangular | All four sides parallel; front = back, left = right. | Easiest to plan, most predictable resale. |
| Square | All four sides roughly equal. | Excellent for villa-style houses; resale strong. |
| Tapered (front-wider) | Front is wider than back, depths similar. | Good front presence, slightly less back area. Generally fine. |
| Tapered (back-wider) | Back is wider than front, depths similar. | Narrow road frontage; parking and entrance need careful design. |
| Trapezium / Wedge | One depth is meaningfully longer than the other. | Diagonal back wall; rooms at the back may have angled corners. |
| L-shape | A bite taken out of one corner. | Use the inner L for courtyard or garage; needs custom layout. |
| Highly irregular | Multiple non-parallel sides or bent boundaries. | Likely needs custom surveyor work and bespoke architectural design. |
When an irregular plot is still worth buying
Pakistani buyers often pass on irregular plots automatically. That’s a mistake when the upside is real. Consider these positives:
- Discount. Irregular plots typically sell 10–20% cheaper per Marla. If the layout still allows a good house, that’s real money saved.
- Corner advantage. Many irregular plots are corner plots, which offer two sides of frontage and stronger commercial conversion potential.
- Front width is what matters. A wedge-shaped plot with a wide front still parks cars and frames a house well, even if the back is narrower.
- Privacy. Angled back walls can put your private spaces (master bedroom, courtyard) away from neighbours.
- Custom design opportunity. A good architect turns an awkward shape into a one-of-a-kind home that resells to buyers who want something unique.
When to walk away from an irregular plot
- Front width below 25 ft for a 5 Marla house or below 30 ft for a 10 Marla house — parking and entrance become tight.
- Depth less than 50 ft for any residential plot — very hard to fit a functional house with proper setbacks.
- One side has an angle below 70° — severe internal corners are unusable.
- The advertised area doesn’t match this calculator’s estimate by more than 5% — usually a red flag about either the seller or the title document.
- The neighbours’ back walls cut into your plot — possible encroachment dispute. Walk away unless title is air-tight.
Plot orientation and Pakistani buyer preferences
Orientation matters as much as shape in Pakistani resale. East-facing and north-east facing entrances are most preferred — cooler summers, better morning light, and stronger feng-shui / vastu appeal for some buyers. South-facing plots get harsh afternoon sun and command lower premiums. West-facing plots can be tough to sell in Multan’s climate without good shading and ventilation. Note the orientation alongside the shape when you measure.
Typical Pakistani plot dimensions
| Plot Size | Typical Front (ft) | Typical Depth (ft) | Total Area (sq ft, Punjab Marla) |
|---|---|---|---|
| 3 Marla | 20–22 | 36–40 | ~810 |
| 5 Marla | 25–30 | 45–50 | ~1,350 |
| 7 Marla | 30–32 | 60–65 | ~1,890 |
| 10 Marla | 35–40 | 65–75 | ~2,700 |
| 1 Kanal | 50–65 | 80–100 | ~5,400 |
| 2 Kanal | 80–100 | 100–130 | ~10,800 |
Dimensions vary by society and authority. DHA, Bahria, and government schemes each use their own standard plot sizes. Always check the official site plan for the exact dimensions of the plot you’re buying.
Questions to ask before buying an irregular plot
Plot shape glossary
- Frontage
- The road-facing side of the plot. Wider frontage usually commands a price premium and resells faster.
- Depth
- The distance from the road-facing front to the back boundary. Measured along the left and right sides.
- Setback
- The mandatory distance you must leave between your house wall and the plot boundary. Reduces usable building area.
- Building line
- An imaginary line on the plot beyond which construction is allowed. Typically set by the authority or society bylaw.
- Trapezium plot
- A plot where front and back are parallel but of different widths, or left and right depths differ. Very common in Pakistan.
- Wedge plot
- A plot that tapers significantly from front to back, like a piece of pie. Often discounted in price.
- Corner plot
- A plot at the intersection of two roads. Two sides of frontage; typically priced 10–15% higher.
- Punjab Marla
- Official Punjab Marla = 270 sq ft (board-certified). Some older documents use 272.25 sq ft.
- Society Marla
- Some private housing societies use a 225 sq ft Marla. Always confirm the Marla standard in the society’s bylaws.
- Total Station / Theodolite
- Surveying instruments that measure angles and distances precisely. Used for legal-grade plot measurement.

Frequently asked questions
How does this plot shape calculator estimate area?
It averages the front and back widths, averages the left and right depths, then multiplies the two averages. This trapezium approximation works well for most tapered Pakistani plots. For severely irregular plots with bent sides, get a proper surveyor measurement.
Is the area exact?
No. This is a planning estimate. For legal-grade area, use approved drawings from the authority, a surveyor with theodolite or total station, or the official mutation/registry records.
Is an irregular plot bad?
Not always. Irregular plots can sell at 10–20% discount per Marla, which is real money saved if the layout still allows a good house. The decision comes down to front width, depth, internal angles, and how well an architect can resolve the shape.
Which plot shape is easiest to build on?
A rectangular plot with similar front and back widths, and similar left and right depths, is the easiest. Square plots come next. Mild tapering with a wider front is usually fine for residential houses.
Why are there different Marla standards?
Punjab’s official Marla is 270 sq ft (board-certified). Older Punjabi records may use 272.25 sq ft. Some private housing societies in Pakistan use a 225 sq ft Marla. Always confirm which Marla applies before computing area.
What is a good front width for a 5 Marla house?
25 to 30 feet is typical and comfortable. Below 22 feet, parking and entrance become tight; 30+ feet feels generous and resells well. The front width matters far more than total area for a house’s feel.
How do I measure plot angles?
This tool doesn’t require angle input — just four side measurements. If you need exact angles for an irregular plot, you need a surveyor. Pacing or eyeballing angles introduces too much error.
What if the advertised area doesn’t match the calculator’s estimate?
If your measured estimate differs from the advertised area by more than 5%, ask the seller for the source document (mutation, registry, or society plan). Common reasons include different Marla standards, old measurement, or, occasionally, misrepresentation.
