# how to measure speaker size

## Introduction

If you're buying speakers for your home or car, you might be wondering how to measure speaker size. The answer is not as simple as it seems: there are a few different factors that contribute to speakers' dimensions and shape. But with a little math and basic knowledge of audio equipment, anyone can figure out exactly how big their sound system is!

## Measure both the height and width of your speaker.

You can measure your speaker in two different ways, both of which are equally effective.

• Measuring from the edge of one side to the edge of the other: This will give you an accurate measurement for both width and height, so it's a good way to go if your speaker has no built-in proportions. Just remember to keep in mind that some speakers have rounded edges and others have sharp angles, so if it's not clear what you should be measuring against, try taking some photos first!

• Measuring just one dimension: If your speaker is rectangular or square (or something similar), this option might work better for you because it only requires one measurement rather than two separate ones. It also gives you more options overall since many speakers come in different shapes and sizes but again, make sure not all those dimensions are equal before deciding which one makes sense for yours!

## Multiply the numbers you got in step one.

To get the total volume of your speaker, multiply the height and width measurements you got in step one.

For example: If I have a speaker that is 15 inches tall by 10 inches wide, then my formula would be (15 x 10) = 150 cubic inches.

Multiply these two numbers if you can get a whole number as an answer; otherwise, round up or down to one decimal place (0.1).

## Divide that number by 12 to find the size of your speaker in inches.

You can use the following formula to figure out how big your speaker is:

• Divide the diameter of your speaker by 12.

• The answer will be in inches (or centimeters, if you're using that system).

## To find the size of your speaker in square feet, divide this last number by 144.

You can find the size of your speaker in square feet by dividing this last number by 144. In other words, multiplying it by 12 and then dividing it by 12. You won’t have to flip back through your notes or count on your fingers!

## If you have questions about how big your speakers are, it's easy to figure out with a basic calculation

If you're wondering how to measure speaker size, it's easy to figure out with a basic calculation. The formula for calculating the volume of a speaker is:

Volume = Length * Width * Height in cubic feet (ft3)

• or in cubic meters (m3). You can convert units by multiplying by 35.32, which is the conversion factor between feet and meters. For example, if your speaker measures 2 ft x 4 ft x 6 in, then its volume would be:

## Conclusion

We hope this guide has been helpful. Remember that it's always better to measure your speakers than guess at their size, since you don’t want them to be too small or too big for the room where they'll live.
