Marla Is Not One Value

The Punjab revenue/official standard uses 272.25 sq ft per Marla (1 Kanal = 5,445 sq ft). Many Lahore and other private-housing-scheme conversions instead use 225 sq ft per Marla (1 Kanal = 4,500 sq ft) — a 21% difference. Always confirm which standard a specific plot's paperwork uses before relying on a conversion.

Bigha and Biswa sizes vary genuinely by region and era — this converter uses the Kanal-linked convention (1 Bigha = 4 Kanal = 20 Biswa), documented on our rate reference page.

Frequently Asked Questions

Is a Marla always 225 square feet?

No — this is the single most common source of conversion errors. The Punjab revenue/official standard is 272.25 sq ft per Marla, while many Lahore and other private-housing-scheme conversions use 225 sq ft instead, a 21% difference. Always check which standard applies to a specific plot's paperwork before converting its size.

How many Marla are in a Kanal?

Always 20, regardless of which Marla standard you're using — 1 Kanal is 20 Marla under both the Punjab revenue standard (5,445 sq ft) and the Lahore private-scheme standard (4,500 sq ft). It's the size of a single Marla, not the Marla-to-Kanal ratio, that varies.

Why do Bigha and Biswa conversions vary so much between sources?

Because they genuinely are defined differently in different regions and revenue systems — some define Biswa as a small fraction of a Marla, others as a much larger fraction of an acre. This calculator uses the Kanal-linked convention (1 Bigha = 4 Kanal = 20 Biswa) since it's consistent with the rest of the Punjab revenue system, but if your paperwork uses a different regional convention, treat the Bigha/Biswa figures here as one documented reference point rather than a universal constant.

1 killa mein kitna marla hota hai? (How many Marla in one Killa?)

1 Killa equals 1 Acre exactly — Killa is simply the Punjabi/revenue-record term for an Acre, used interchangeably in land records across Punjab. Under the Punjab revenue Marla standard, that works out to 160 Marla (8 Kanal). Type any value into the calculator above with Killa as the source unit to convert it instantly, including under the Lahore private-scheme standard if that's what your paperwork uses.

Is a Killa the same as an Acre?

Yes, exactly — 1 Killa = 1 Acre = 43,560 sq ft. "Killa" is the term used in Punjabi and revenue-department land records; "Acre" is the same unit's English/international name. Neither varies by region the way Marla does.

Land measurement in Pakistan runs on two parallel systems that trip up buyers, sellers, and even some agents: the Marla/Kanal system used in official revenue records and most of Punjab, KP, and Islamabad, and the metric/imperial system (square feet, square yards, acres) used internationally and increasingly in newer housing schemes.

Why "one Marla" isn't always the same number

The Marla itself isn't perfectly standardized nationwide — the Punjab revenue standard Marla (used in official land records, or Fard, across most of the province) differs from the private housing-scheme Lahore standard some developers use in their marketing and site plans, and both differ again from historical or regional variants you might encounter in older documents. This converter defaults to the Punjab revenue standard, since that's what governs official paperwork, but it's worth explicitly confirming which standard a specific document or listing is using before assuming a "5 Marla plot" means the same square footage everywhere.

A worked example

A plot advertised as "5 Marla" by a private housing scheme's marketing material and a "5 Marla" figure on an official revenue record for a different property can correspond to genuinely different square footage, if the two are using different Marla definitions — this is exactly the kind of discrepancy that causes real disputes at the point of sale, not a hypothetical edge case.

How this connects to your other property calculations

Once you know a plot's true area in a consistent unit, the Construction Cost Calculator uses covered area (not plot area) to estimate build cost, and the Covered Area Planner tells you the maximum buildable footprint on a given plot size under typical bylaws — land area, covered area, and buildable area are three related but distinct numbers, and this converter only handles the first of the three.

Common mistakes

Buyers frequently take a plot size figure from one source (a broker's listing, a developer's brochure, an old family document) at face value without confirming which Marla or unit standard it's using — always cross-reference against the property's actual revenue record (Fard) or an official survey before treating any stated area as final, especially for older properties or informal transactions.
