Enter the length, width, and thickness in inches of the MDF (medium density fiberboard) into the calculator to determine the weight.

MDF Weight Formula

The following formula is used to calculate the weight of a piece of medium-density fiberboard (MDF).

MDF-W = L * W * T * D

  • Where MDF-W is the weight of the medium denity fiberboard (lbs)
  • L is the length of the fiberboard (inches)
  • W is the width of the fibreboard (inches)
  • T is the thickness of the fibreboard (inches)
  • D is the density fo teh fibreboard (lbs/in^3)
    • For MDF this is typically .025 lbs/in^3

To calculate the MDF, first, multiply the length, width, and thickness of the board, then multiply the result by the density of the MDF, which is equal to around.025 lbs per cubic inch (lbs/in^3).

What is the weight of MDF?

The weight of a medium-density fibreboard depends on the total volume of the piece of MDF and the density. In general, MDF has a consistent density of around .025 lbs/in^3.

How to calclulate the weight of MDF?

Example Problem:

The following example outlines how to calculate the weight of MDF.

First, determine the length of the MDF. For this example, the length is measured to be 20 inches.

Next, determine the width of the MDF. In this example, the width is 10 inches.

Next, determine the thickness of the MDF. This piece of MDF is 2 inches. thick.

Finally, calculate the weight of the MDF using the dimensions above along with the density of .025 lbs/in^3.

MDF-W = L * W * T * D

MDF-W = 20*10*2 *.025

MDF-W = 10 lbs
