Glass Weight Calculator
Glass Weight Calculator – Accurate, Easy, and Reliable
The Glass Weight Calculator helps you quickly find the total weight of any glass sheet based on its length, width, thickness, density, and shape. Whether you’re working on window panels, doors, tabletops, mirrors, or architectural glass, this tool provides fast and precise results in kilograms and pounds.
This calculator is ideal for builders, architects, interior designers, glass manufacturers, and DIY enthusiasts who need accurate glass weight estimates for transport, installation, or structural design planning.
How the Glass Weight Formula Works
The weight of glass is determined using this simple formula:
Glass Weight (kg) = Area (m²) × Thickness (m) × Density (kg/m³) × Number of Pieces
Where:
Area (m²) = Length × Width for rectangular glass
Area (m²) = π × (Diameter / 2)² for circular glass
Thickness (m) = Glass thickness in meters (1 mm = 0.001 m)
Density (kg/m³) = Depends on the glass type:
Soda-lime glass: 2500 kg/m³
Borosilicate glass: 2230 kg/m³
Lead glass: 3100 kg/m³
Acrylic: 1180 kg/m³

Example Calculation
Let’s calculate the weight of a rectangular glass with these dimensions:
Length = 1.5 m
Width = 1.0 m
Thickness = 10 mm (0.01 m)
Density = 2500 kg/m³ (standard glass)
Pieces = 1
Area = 1.5 × 1.0 = 1.5 m²
Weight = 1.5 × 0.01 × 2500 × 1 = 37.5 kg
So, the glass sheet weighs 37.5 kilograms (82.67 pounds) approximately.
Common Glass Densities
| Glass Type | Density (kg/m³) | Description |
|---|---|---|
| Soda-Lime Glass | 2500 | Most common type used in windows and mirrors |
| Borosilicate Glass | 2230 | Heat-resistant, used in labs and cookware |
| Lead Glass | 3100 | Heavier and more reflective, used in crystal glass |
| Acrylic Glass | 1180 | Lightweight plastic alternative to glass |
Why Accurate Glass Weight Matters
Accurate weight calculation is essential for:
Architectural load design
Transportation and logistics
Safety during installation
Cost estimation and pricing
Knowing the glass weight ensures the structure can handle the load safely and helps in choosing the right frame and support material.

FAQs – Glass Weight Calculator
1. How do I calculate the weight of glass manually?
Use the formula: Area × Thickness × Density. Multiply your area in square meters by the thickness (in meters) and by the glass density (kg/m³).
2. What is the density of standard window glass?
The density of standard soda-lime glass is approximately 2500 kg/m³.
3. How do I convert glass weight from kilograms to pounds?
Multiply the weight in kilograms by 2.20462 to get the weight in pounds.
4. Can I use this calculator for tempered or laminated glass?
Yes. Tempered glass has the same density as standard glass. For laminated glass, include the thickness of each layer and the interlayer.
5. What is the average weight of 10mm thick glass per square meter?
10mm thick glass weighs about 25 kg per square meter.
6. Why is calculating glass weight important?
It helps ensure proper support design, transport capacity, and installation safety.
7. Does this calculator support both metric and imperial units?
Yes. It automatically displays results in kilograms (kg) and pounds (lb).
