This calculator gives you both. Enter a pane size and thickness and it returns the area in square feet and the theoretical weight in kilograms, then prices it at the rate your glass shop quoted. You can add pane after pane to build a complete list for a job, with edge work and fitting as separate lines.

What This Tool Does

It calculates area and weight for each pane, keeps a running list of all the panes in your job, and totals the area, weight and cost. Edge work or holes are added per pane, and fitting is added once for the whole job, so the breakdown reflects how glass is actually quoted.

Who It Is For

• Homeowners replacing a broken pane or pricing glass for a renovation.
• Shop and office owners working out the glass in a shopfront or partition.
• Glaziers and fabricators who want a quick weight check before deciding how many people the installation needs.
• Anyone checking a glass quote against the area actually being supplied.

How To Use It

1. Measure the pane, or the opening it has to fill, width and height.
2. Pick the thickness. Three to six millimetres covers ordinary windows, eight to twelve covers doors, partitions and shower cabins, and fifteen to nineteen is for heavy structural glazing.
3. Choose the glass type. This changes the price and the safety behaviour, though not the weight calculation.
4. Enter how many identical panes you need.
5. Add the rate your glass shop quoted per square foot, plus any edge work or hole charge per pane.
6. Add a fitting charge for the whole job if you have one, then add the pane. Repeat for each different size.

Inputs And Units Explained

• Pane width and height — the finished glass size, or the opening if the glazier will take their own deductions. Say which you have given them.
• Thickness — in millimetres, from 3 mm to 19 mm. This is the single biggest driver of both weight and price.
• Glass type — clear, tinted, frosted, tempered or laminated. Tempered and laminated are the safety glasses.
• Number of panes — how many of this exact size.
• Rate per square foot — what your glass shop quoted for this type and thickness.
• Edge work or holes per pane — polishing, bevelling or drilled holes for hinges and handles.
• Fitting for the whole job — added once to the total rather than per pane.

How The Calculation Works

Area is width times height. Weight uses the published density of ordinary soda-lime glass, 2,500 kg per cubic metre, which works out to a convenient rule: glass weighs 2.5 kg per square metre for every millimetre of thickness. So 8 mm glass is 20 kg per square metre and 12 mm is 30 kg per square metre. The tool multiplies your area by that figure.

Cost is the area times your rate, plus your edge work charge, multiplied by the number of panes, with the job fitting charge added at the end. Tempered and laminated glass are priced differently by suppliers, which is why the rate is yours to enter rather than something the tool assumes.

Worked Example

Two panes of 8 mm clear glass, each 6 feet by 4 feet, for a shop counter top and back panel.

Input or result	Value
Pane size	6 ft × 4 ft
Area per pane	24 sq ft (2.23 m²)
Thickness	8 mm clear
Weight per pane	about 44.6 kg
Panes	2
Total area	48 sq ft
Total weight	about 89 kg

Nearly 45 kg per pane is the figure worth knowing before the delivery arrives. At the rate the glass shop quoted, the tool prices the 48 square feet, adds edge polishing per pane and the fitting charge, and gives a total you can compare against the written quote.

Features And Benefits

• Area and weight together, which is what you need for both pricing and handling.
• A pane list that builds up across a whole job rather than one calculation at a time.
• Edge work per pane and fitting per job, matching how glass is really quoted.
• CSV export of the pane schedule for your records or your glazier.
• Clear separation between what is arithmetic and what is a safety decision.

Assumptions And Accuracy Limits

• Weight assumes ordinary soda-lime glass at 2,500 kg per cubic metre. Laminated panes include an interlayer and differ slightly.
• The tool does not recommend a thickness. Choosing glass for a door, partition, railing or shower is a safety decision for your installer.
• Tempered glass must be made to final size before toughening, so remeasure before ordering. It cannot be cut afterwards.
• Prices come only from the rates you type in.

Common Mistakes To Avoid

• Ordering tempered glass from a rough measurement. Toughened glass cannot be trimmed on site. A pane that is 10 mm too wide is scrap.
• Underestimating weight on upper floors. Work out the weight before the delivery, not when it is standing in the street.
• Using ordinary glass in a safety location. Doors, partitions, showers and anything at floor level should be tempered or laminated. If a quote is unusually cheap, check which one it is for.
• Comparing rates for different thicknesses. A rate for 5 mm against a rate for 8 mm tells you nothing useful.

Glass Price In Pakistan: Thickness, Type And Weight

People searching for the price of 8 mm or 12 mm glass in Pakistan are usually comparing plain, tempered and laminated glass without realising how much the thickness changes the weight. Twelve millimetre glass is heavy enough that a single large panel needs two or three people and the right fittings, which affects installation as well as price.

Enter the panel size, the thickness and the rate you were quoted for plain or tempered glass. The tool shows the area, the weight and the total, and warns you when a panel is heavy enough to need special handling.
