Enter the height, width, thickness, and density of the glass into the calculator to determine the glass weight.

Glass Weight Formula

The following equation is used to calculate the Glass Weight.

GW = H*W*T*D
  • Where GW is the glass weight (lbs)
  • H is the height of the glass (in)
  • W is the width of the glass (in)
  • T is the thickness of the glass (in)
  • D is the density of the glass (lbs/in^3)
    • The average density of glass is .0903 lbs/in^3

To calculate the glass weight, multiply the glass height, width, thickness, and density together.

What is a Glass Weight?


Glass weight is a measure of the mass of a panel of glass. This value depends on the physical characteristics of the glass, including the density of the glass.

How to Calculate Glass Weight?

Example Problem:

The following example outlines the steps and information needed to calculate Glass Weight.

First, determine the height, width, and thickness. For this example problem, these are measured as 40 inches, 15 inches, and 1 inch respectively.

Next, determine the density of the glass. For this example, we will use the average density of .0903 lbs/in^3.

Finally, calculate the glass weight using the formula above:

GW = H*W*T*D

GW = 40*15*1*.0903

GW = 54.18 lbs
