Enter your Glass Type, Shape, Thickness, and dimensions — Length & Width for rectangles, Radius for circles, or Base & Height for triangles — and the Glass Weight Calculator gives you the total weight along with the area, volume, and density of your glass panel.

Glass density varies by type: Annealed glass (2500 kg/m³), Tempered glass (2500 kg/m³), Laminated glass (2540 kg/m³), and Alkali silicate glass (2300 kg/m³). These densities are used to calculate the weight based on volume.
Glass weight is calculated by multiplying glass density by glass volume. The volume is determined by the glass area (length × width for rectangular) multiplied by thickness. Formula: Weight = Density × Area × Thickness.
A standard window glass panel (100cm × 80cm × 6mm) weighs approximately 12 kg. The weight varies significantly based on dimensions, thickness, and glass type used.
Annealed and tempered glass have the same density (2500 kg/m³), so they weigh the same for identical dimensions. The difference lies in strength and safety properties, not weight.
To convert from kilograms to pounds, multiply by 2.205. To convert from pounds to kilograms, multiply by 0.454. Our calculator automatically handles conversions based on your selected unit system.
Yes, glass thickness directly affects weight as it determines volume. Doubling the thickness doubles the weight. For example, 12mm glass weighs twice as much as 6mm glass of the same dimensions.
The calculator uses standard glass densities and provides accurate estimates for planning purposes. Actual weight may vary slightly due to manufacturing tolerances and specific glass compositions.
The calculator supports rectangular, square, circular, and triangular shapes. For irregular shapes, you can break them down into basic shapes and calculate each section separately.
