Calculating the required amount of acoustic foam for a room can be crucial for achieving optimal sound quality. To simplify this process, we’ve developed an easy-to-use calculator that accurately determines the amount of acoustic foam needed based on room dimensions and other factors.

How to Use

Simply input the dimensions of your room and the desired coverage percentage into the calculator below. Then click the “Calculate” button to instantly get the required amount of acoustic foam.


The formula used to calculate the required amount of acoustic foam is:

Foam Area=Room Area×(Coverage Percentage/100)

Example Solve

Suppose we have a room with dimensions:

  • Length: 10 feet
  • Width: 8 feet
  • Height: 9 feet

And we want to achieve 80% coverage. Using the formula:

Foam Area=(10×8×9)×(80/100)


=576 square feet

So, we would need 576 square feet of acoustic foam to achieve 80% coverage in this room.


Q: What is acoustic foam used for?
A: Acoustic foam is used to improve the sound quality within a room by reducing unwanted echoes and reverberations.

Q: How do I determine the coverage percentage?
A: The coverage percentage represents the proportion of wall space you want to cover with acoustic foam. It’s typically recommended to cover between 50% to 80% of the wall area.

Q: Can I use this calculator for irregularly shaped rooms?
A: This calculator assumes the room is rectangular. For irregularly shaped rooms, you may need to manually calculate the foam area or approximate the dimensions.

Q: Is acoustic foam installation difficult?
A: Installing acoustic foam is generally straightforward and can be done using adhesive or mounting hardware. However, it’s essential to follow manufacturer guidelines for best results.


With the help of our acoustic foam calculator, determining the required amount of foam for your room is quick and hassle-free. Achieving optimal sound quality has never been easier!
