Speaker Coverage Calculator

Coverage Area (sq m):



Are you in need of a quick and efficient way to determine the coverage area for your speakers? Look no further! In this guide, we will show you how to create an HTML Speaker Coverage Calculator using a straightforward formula. Whether you’re setting up a sound system for an event or designing a home theater, this tool will help you calculate the coverage area with ease.

How to Use

To use the HTML Speaker Coverage Calculator, follow these steps:

  1. Input Parameters: Enter the diameter of the speaker (in meters) and the horizontal coverage angle (in degrees) in the provided fields.
  2. Click Calculate: After entering the values, simply click the “Calculate” button to initiate the calculation.
  3. View Results: The coverage area (in square meters) will be displayed below the button.


The formula used to calculate the coverage area is:

Coverage Area (CA) = π * (Diameter/2)^2 * (Horizontal Coverage Angle/360)


  • CA: Coverage Area (in square meters)
  • Diameter: Diameter of the speaker (in meters)
  • Horizontal Coverage Angle: Horizontal coverage angle of the speaker (in degrees)


Let’s say you have a speaker with a diameter of 0.5 meters and a horizontal coverage angle of 90 degrees. Here’s how you can calculate the coverage area:

CA = π * (0.5/2)^2 * (90/360) CA ≈ π * (0.25)^2 * 0.25 CA ≈ π * 0.0625 * 0.25 CA ≈ π * 0.015625 CA ≈ 0.04909 square meters

So, the coverage area is approximately 0.04909 square meters.


Q1: Can I use this calculator for speakers of any size?

Yes, this calculator can be used for speakers of any size, as long as you provide the diameter and horizontal coverage angle.

Q2: What is the value of π in the formula?

The value of π (pi) is approximately 3.14159, but you don’t need to input it manually; the calculator handles it.

Q3: Can I embed this calculator on my website?

Yes, you can easily embed this calculator on your website by copying the provided HTML and script code.

Q4: Is this calculator suitable for outdoor speaker setups?

Yes, you can use this calculator for both indoor and outdoor speaker setups.


Creating an HTML Speaker Coverage Calculator is a practical way to determine the coverage area for your speakers quickly and accurately. With a simple formula and a user-friendly interface, you can streamline your sound system setup process. Feel free to customize and embed this calculator on your website for added convenience in your audio projects.
