What is the difference between covered area and plot area?

Covered area (what this calculator sums) is the enclosed floor space inside the walls of a building — what you can walk on. Plot area is the outer boundary of the land. A 1 Kanal plot at 5,440 sq ft might have a 2,500 sq ft single-storey house on it, with the remaining 2,940 sq ft as lawn, driveway, servant quarter, and parking. Both numbers are meaningful but they answer completely different questions. Real-estate listings sometimes blur the two — always ask which one a quoted figure refers to.

How do I handle L-shaped rooms or irregular spaces?

Split the room mentally into non-overlapping rectangles, enter each as its own 'room' in the calculator, and the tool sums them automatically. An L-shape becomes two rectangles. A T-shape becomes two or three. Label them clearly so you do not double-count later — 'living area main' and 'living area extension' is much safer than 'living 1' and 'living 2'. For curved or genuinely irregular shapes (very rare in Pakistani residential), use the closest rectangular approximation and accept a 5 percent error.

Does this calculator save my entries?

No. Everything resets when you refresh the page or navigate away. All data stays in your browser session for privacy — nothing leaves your device or is stored on any server. If you need the totals later, take a screenshot or write the numbers down before you close the page. Most users redo the calculation each time they revisit, which only takes a couple of minutes.

Why does the result show area in Marla?

Because Pakistani real estate and construction conversations happen in Marla — especially in Punjab and KPK — and a number expressed only in sq ft or m squared is not immediately useful to most local buyers, sellers, contractors, or estate agents. Showing Marla alongside the metric and imperial units lets you instantly cross-reference property listings and construction quotes that quote in the traditional unit. A 10 Marla house at the 272 sq ft Marla equals 2,720 sq ft — a useful anchor to memorise.

How is this different from the Square Footage Calculator?

The Square Footage Calculator handles one rectangle at a time — ideal for a single room, a single plot, or a single material estimate. The Room Area Calculator is built for whole-home aggregation — enter every room one after another and watch the running total. Use the first when measuring one space, the second when you need a whole-home figure for material ordering, AC sizing, or per-sq-ft renovation cost comparison.

Should I include exterior walls in my measurements?

Depends on what you need. For flooring, paint, furniture planning — measure interior dimensions only (between the inside faces of the walls). For architectural drawings or real-estate 'built-up area' figures — include the exterior walls (measure outside-face to outside-face). Interior measurements usually come out 10 to 12 percent smaller than built-up area, which is enough to matter when you are comparing two listings or budgeting materials.

How do I convert my total to Marla for a real-estate comparison?

The calculator already shows Marla alongside sq ft, so you do not have to do the math by hand. If you do need the manual version: divide total sq ft by 272 to get Marla in the standard system. A 2,500 sq ft house equals 2,500 divided by 272, about 9.19 Marla. For listing comparisons, round to the nearest half-Marla — buyers and sellers in Pakistan rarely deal in fractions smaller than that.

Quick Answer

Add the area of every room in a house — bedrooms, living, kitchen, bathrooms, corridors — to get total covered area in sq ft, sq m and Marla for renovation planning.

Overview — Room Area Calculator

Construction

A room area calculator sums the area of multiple rooms in a house or building to give you a total floor area in square feet, with conversions to square meters and Marla. Enter each room's length and width — bedrooms, living rooms, kitchen, bathrooms, corridors — and the tool maintains a running total. This is invaluable for estimating materials (flooring, paint, wallpaper), comparing homes, calculating per-square-foot renovation costs, sizing heating and cooling requirements, and verifying a property listing's claimed area against actual measurements.

Formula

Total Area = Σ (Length × Width) for each room. Conversions: ÷ 10.764 for m², ÷ 272 for Marla.

A typical 5 Marla home (1,360 sq ft) contains ~7 rooms averaging 200 sq ft each (inc. bathrooms).

A 10 Marla home (2,720 sq ft) fits 10–12 rooms including a separate lounge, dining, and 4 bedrooms.

A 1 Kanal home (5,440 sq ft) allows spacious rooms averaging 400 sq ft, a lawn, and a dedicated drawing room.

From the editors — what to know before you start

If you are about to renovate, repaint, replace flooring across the whole house, or just want to verify what the property listing actually means by '10 Marla covered area', this is the calculator that turns a confusing pile of room dimensions into one usable total. Enter each room — bedroom, drawing room, kitchen, bath, corridor, staircase landing — one at a time, and the tool keeps a running sum across all of them with instant conversion to square meters and Marla. Where it earns its keep is in the moments people typically get the math wrong: forgetting the corridor that runs through the house (often 80 to 120 sq ft of flooring you have to buy), counting the staircase footprint twice (once as floor area on the ground floor and again as the stair itself), or forgetting that built-up area (which the listing quoted) includes the wall thickness while covered area (which you actually walk on) does not. Honest take: for any whole-home material order — flooring, paint, tile, AC sizing — always do this calculation first, then add 10 percent wastage for materials and round up. Skipping the room-by-room aggregation is the single biggest reason homeowners end up with mid-renovation supplier visits and dye-lot mismatches.

Pro tips most people learn the hard way

Add every room you plan to treat — including corridors, staircase landings, and closets if you are flooring or painting them. The most common mistake on a whole-home material order is forgetting the corridor, which on a typical 10 Marla Pakistani house is 80 to 120 sq ft of material you suddenly need on day two.
Covered area (what you walk on, inside the walls) and built-up area (covered plus wall thickness) differ by 10 to 12 percent. Real-estate listings sometimes quote built-up to make the number look bigger. For material ordering, always use covered area — you do not buy flooring for the wall thickness.
L-shaped rooms become two rectangles in this calculator. T-shapes become two or three. Split mentally, enter each piece as its own 'room' with a clear label, and the tool sums them. For genuinely curved spaces (rare in Pakistani residential), the closest rectangular approximation with a 5 percent accuracy buffer works fine.
AC sizing uses 20 to 30 BTU per hour per square foot for Pakistani climates. A 1,500 sq ft house needs roughly 30,000 to 45,000 BTU/hr of cooling — about 2.5 to 3.5 tons of split AC capacity. Multiply your room-by-room total by the climate-adjusted BTU rate to size your AC accurately, before the salesman upsells you a bigger system.
After you get the total, divide by 272 for Marla in the standard system. A 2,500 sq ft house is roughly 9.19 Marla. Round to the nearest half-Marla for listing comparisons — that is the precision Pakistani buyers and sellers actually negotiate in.

?What is the Room Area Calculator?

The Formula

Total Area = Σ (Length × Width) for each room. Conversions: ÷ 10.764 for m², ÷ 272 for Marla.

Each rectangular room's area is length times width. Summing the areas of all rooms gives the total floor area — which is what you typically need for whole-home material estimates, cleaning quotes, HVAC sizing, and real-estate valuation. The calculator handles any number of rooms and is particularly useful when different rooms have different shapes and you want a single total without manual addition.

Put It in Perspective

A typical 5 Marla home (1,360 sq ft) contains ~7 rooms averaging 200 sq ft each (inc. bathrooms).

A 10 Marla home (2,720 sq ft) fits 10–12 rooms including a separate lounge, dining, and 4 bedrooms.

A 1 Kanal home (5,440 sq ft) allows spacious rooms averaging 400 sq ft, a lawn, and a dedicated drawing room.

US building code minimum bedroom size is 70 sq ft — Pakistani homes typically size bedrooms 2–3× that.

Practical Examples

A typical home: Bedroom (12 × 14) + Living (15 × 18) + Kitchen (10 × 12) + Bath (8 × 6) totals 546 sq ft — enough to plan materials for a full cleanup.

Useful when planning a whole-home flooring or repainting project — the total dictates how many boxes or liters to buy.

Real-estate listings often quote total covered area; this tool lets you independently verify by room.

When dividing a renovation cost by area, using the accurate total gives a fair per-square-foot price for comparison.

Splitting construction costs across multiple buyers (joint ownership) often requires verifying each family's share of total area — use room-by-room entries.

HVAC system sizing typically needs 20–30 BTU/hr per square foot for cooling, so a 1,500 sq ft home needs roughly 30,000–45,000 BTU/hr of cooling capacity.

Frequently Asked Questions

Include whatever you actually want counted. For materials estimation — flooring, paint, AC sizing — include every floor surface you plan to cover or treat. For real-estate-style 'covered area' or 'carpet area' figures, include everything inside the walls but exclude unfinished basements, open balconies, and garages unless they are genuinely living space. The 'right' answer depends on what you are using the total for, so be consistent within a single project.
