Enter the length, width, and thickness of the piece of plywood into the calculator to determine the weight.

Plywood Weight Formula

The following formula is used to calculate a plywood weight.

PW = L*W*T/12 * D
  • Where PW is the plywood weight (lbs)
  • L is the length of the plywood (ft)
  • W is the width of the plywood (ft)
  • T is the thickness of the plywood (in)
  • D is the density of the plywood (lbs/ft^3)
    • the average density of plywood is 37.5 lbs/ft^3, but you can adjust the density in the calculator to account for different types of plywood

To calculate plywood weight, multiply the length, width, and thickness to get volume, then multiply by the density.

What is the weight of plywood?

A standard 4×8 foot piece of plywood that is .500 inches thick weighs around 50 lbs.

How to calculate the weight of plywood?

Example Problem:

The following example problem outlines the steps needed to calculate the weight of a piece of plywood.

First, determine the length of the plywood. In this case, the length is measured to be 8 feet long.

Next, determine the width of the plywood. For this piece of plywood, the width is measured to be 4 feet long.

Next, determine the thickness of the plywood. This piece of plywood is .750 inches thick.

Next, determine the density of the plywood. This will vary depending on the type of plywood, but the average is 37.5 lbs/ft^3 and this is what we will use for this example.

Finally, calculate the weight of the plywood using the formula above:

PW = L*W*T/12 * D

PW = 4*8*.750/12 * 37.5

PW = 75 lbs
