In order to help you make an informed decision on which speakers fit your requirements, we have created a list of questions that can help point you in the right direction when it comes to selecting the perfect speakers for your home theater or office space!

What You Need When Measuring The Speaker Size

We need equipment as follows

A Vernier Calliper

It’s a measuring tool used to measure the precise thickness and width of materials, distances between surfaces and other small spaces.

A Measuring Tape

Typically, the best choice for measuring speaker diagonals is a retractable steel tape measure with notches every foot.

A pencil and paper for recording measurements.

Finding The Speaker Dimensions

Remove The Speaker From Its Housing

Take off any covers on the front of the speaker. If the speaker has a grill, remove that too.

Find The Speaker's Width

Measure along both outer edges, between two notches or reference marks on either side of the housing.

Measure Speaker Width

Measuring speaker width is very straightforward if you have it out of its housing! Make sure to measure both the front and back dimensions for an accurate reading.

Find the speaker's depth

This is trickier because there are no easy reference points to help you measure this dimension accurately! You can do this by placing your measuring tape flat on the floor, so you measure from bottom to top. Place one edge of your tape measure along an outer edge of the speaker’s housing and place it against a wall or other object that will give you another reference point for this measurement.

Find The Speaker's Height

Stand up (or hold your measuring tape) next to the speaker and measure from the bottom of the base plate to the top of the cabinet. Make sure you are not using any feet or other attachments on speakers as they can change their dimensions!

Find The Speaker's Diagonal Size

This is where you use your vernier calliper tool. Place one jaw of the calliper against each outer edge of the cabinet, just below any handles or protrusions that are part of its design and take a measurement between them with no pressure on either side! Record this dimension in inches.

Record Measurements

Write down both width and depth dimensions in inches under “Speaker Dimensions”. Here is the dimensions formula :

Width + Depth = Speaker Dimensions”. To find the diagonal length, just multiply Width x Length and Depth x Length”.

Repeat For The Other Speaker

If you have multiple speakers or a surround sound system, repeat this process with each individual one until you have all of your speaker dimensions.

Find The Volume

Here is a simple formula for finding the total speaker volume: Length x Width x Depth = Total Speaker Volume.

Find The Total Surface Area

This is a simple formula for finding the total speaker size (i.e. surface area): Length x Width = Total Surface Area (in square inches).

Measuring Mounting Holes For New Speakers

  1. Find the outer diameter of the mounting hole: Find the diameter of your speaker holes by using a ruler and marking against the outside edge.
  2. Measure Inner Diameter: Take a drill bit that is larger than the outer diameter, put it through one of your existing mounting holes so you can measure from inside to get an accurate measurement for this step! Mark along the bit where it meets up with the inner edge of the hole.
  3. Now just use a ruler to measure between your markings for the inner diameter! Record this dimension in inches.
  4. Measure Depth: Use a sharpie or marker and mark along both edges of one side at several different points all around its circumference, then draw a line that connects them on the other side as well. This mark represents the depth of your speaker.

Tips for measuring speaker size

Making sure you have a quality tape measure with notches on every foot is very helpful for this job!

A sharpie or marker can help you mark down accurate measurements of both the inner and outer diameter holes.

Marking out both sides of the speaker helps you measure accurately for its depth.

Warning

Remember: Ensure that you have checked all the dimensions for any new speaker you have purchased since size listings can be between various brands and models, so be careful and cautious!

FAQ'S

How should I measure a diagonal's size

Use your vernier calliper tool. Place one jaw of the calliper against each outer edge of the cabinet, just below any handles or protrusions that are part of its design and take a measurement between them with no pressure on either side!”

What are the differences between surface area and volume?

Surface Area refers to how much of a flat plane or flooring that object will cover. Volume measures how much three-dimensional space something takes up, width multiplied by depth multiplied by height!

How do I measure speaker mounting hole diameter?

Measure the outer diameter of your speaker mounting hole by finding the diameter with a ruler and marking it against its outside edge. Then measure inner diameter by putting a drill bit that is larger than the outer, through one of your existing holes to get an accurate measurement from within! Mark along where it meets up on both sides as well!”

What are the steps to measure speaker measurements?

Write down both width and depth dimensions in inches under “Speaker Dimensions”. Here is the dimensions formula : Width + Depth = Speaker Dimensions. To find the diagonal length, just multiply Width x Length and Depth x Length”.” Repeat for the other speaker if you have multiple or a surround sound system.

What is speaker driver size?

Different drivers have different sizes, but in general, the larger the driver, the lower the frequency it was designed for. Many speakers with multiple drivers have crossovers that divide up incoming speaker signals and send them to the appropriate driver.
