Enter the glulam length (ft), the width (ft), and the thickness (ft) into the Glulam Weight Calculator. The calculator will evaluate the Glulam Weight. 

Glulam Weight Formula

The following formula is used to calculate the Glulam Weight. 

GLW = L * W* T * 40.5782


  • GLW is the Glulam Weight (lbs)
  • L is the glulam length (ft) 
  • W is the width (ft) 
  • T is the thickness (ft) 

How to Calculate Glulam Weight?

The following two example problems outline the steps and information needed to calculate the Glulam Weight.

Example Problem #1

  1. First, determine the glulam length (ft).
    • The glulam length (ft) is calculated to be : 10.
  2. Next, determine the width (ft).
    • The width (ft) is measured to be: 5.
  3. Next, determine the thickness (ft).
    • The thickness (ft) is found to be: 5.
  4. Finally, calculate the Glulam Weight using the formula above: 

GLW = L * W* T * 40.5782

The values provided above are inserted into the equation below and computed.

GLW = 10 * 5* 5 * 40.5782 = 10,144 (lbs)

Example Problem #2

The variables required for this problem are provided below:

glulam length (ft) = 12

width (ft) = 12

thickness (ft) = 12

Test your knowledge and check your answer with the calculator.

GLW = L * W* T * 40.5782 = (lbs)
