This builder keeps the list in one place while you walk the house. Add a row per opening with the room name, type, size and quantity, and it totals the glazed area and gives you a first budget if you type in a rough rate. You can save the draft in your own browser, so you can stop halfway, carry on later, and still have the numbers.

What This Tool Does

It builds a room-by-room schedule of every window, door and ventilator, calculates the area of each and the total across the house, counts the openings by type, and applies one rough rate to give a first budget. You can export the schedule as a CSV or print it, and save a draft locally while you work.

Who It Is For

• People building or renovating a house who need one organised list instead of a dozen notes.
• Homeowners getting quotes who want every fabricator pricing the same schedule.
• Contractors preparing a budget before the detailed takeoff.
• Fabricators turning a customer’s rough list into something they can quote.

How To Use It

1. Start in one room and work around the house in a fixed order so nothing is missed.
2. For each opening, add a row: the room name, whether it is a window, door or ventilator, the width and height, and how many of that exact size the room has.
3. Note the system or glass in the last column if you already know it, for example a profile series or 5 mm clear glass.
4. Tap the save draft button now and then. The draft stays in this browser on this device only.
5. When the list is complete, enter a rough all-in rate per square foot for a first budget, then build the schedule.
6. Export the CSV or print it, and send that to every fabricator you ask to quote.

Inputs And Units Explained

• Room — the label you will recognise later. Lounge, Bedroom 1, Kitchen. Be specific enough to find the window again.
• Item type — window, door or ventilator. The counts are reported separately so you can sanity check the list.
• Width and height — the masonry opening, in whatever unit suits your tape.
• Quantity — how many openings of this exact size. Two identical bedroom windows go in one row with a quantity of two.
• System or glass note — optional free text, carried through to the export so the detail is not lost.
• Budget rate — one rough rate per square foot for a first total. Doors and windows really differ, so treat this as an order-of-magnitude figure only.
• House size — context only, for your own records. It never substitutes for measuring each opening.

How The Calculation Works

Each row’s area is width times height times quantity, converted to square feet. The schedule sums those areas and counts openings by type. The first budget is the total area multiplied by the single rate you entered, which is deliberately crude: it is there to tell you whether you are looking at a small job or a large one, not to price the work.

The draft save uses your browser’s own storage. Nothing is uploaded, which also means the draft is only on that device and in that browser, and clearing your browsing data will remove it.

Worked Example

A small house with three openings: a 5 by 4 foot lounge window and two 4 by 4 foot bedroom windows.

Input or result	Value
Lounge window	5 ft × 4 ft × 1 = 20 sq ft
Bedroom windows	4 ft × 4 ft × 2 = 32 sq ft
Total openings	3 windows
Total area	52 sq ft (4.8 m²)

Fifty two square feet at a rough rate gives the first budget. More usefully, the printed schedule means every fabricator quotes the same three openings at the same sizes, which is the only way their numbers can be compared.

Features And Benefits

• One organised list instead of scattered measurements.
• Drafts saved on your device so a half-finished survey is not lost.
• CSV export so the schedule drops into a spreadsheet.
• Counts by type as a sanity check against the house you just walked.
• A printable schedule that makes competing quotes genuinely comparable.

Assumptions And Accuracy Limits

• This is a measurement schedule and a first budget, not a manufacturing takeoff. Final sizes need site verification.
• A single blanket rate across windows and doors will always be approximate, because the two price very differently.
• The draft lives only in this browser on this device. It is not private from anyone else using the same device.
• Nothing here checks whether an opening size is sensible for the system you intend to use.

Common Mistakes To Avoid

• Measuring in a random order. Walk the house the same way every time, room by room, or you will miss an opening.
• Recording the sash size. Measure the masonry opening and let the fabricator take their own deductions.
• Grouping unlike openings. Two windows that differ by even two inches belong on separate rows, because they are separate units to make.
• Trusting the first budget as a quote. It is a scale check. The quotation comes from a measured site visit.

A Window Schedule For New Houses In The Twin Cities

When a new house is built in Bahria Town, DHA or a private society in Islamabad or Rawalpindi, the windows are usually ordered after the structure is complete and the owner is tired of making decisions. A schedule written early, with every opening numbered, sized and typed, saves a great deal of back and forth with the fabricator.

List each opening here once, with width, height, type and room name, and you will have one table to compare quotes against and one list to check against what arrives on site.
