Knowing how to accurately measure drum heads is crucial for drummers who want to replace or upgrade their drumheads. Getting the wrong size can lead to frustrating fits and potentially damage your drums. This guide provides a step-by-step process to ensure you always get the right fit.

Identifying Your Drum Type and Size

Before you even grab your measuring tape, you need to know what kind of drum you're dealing with. Different drums (snare, tom, bass) require different head sizes. Furthermore, even within a drum type, you'll have various diameters.

1. Identifying the Drum Type:

Snare Drum: Typically has a smaller diameter and depth than other drums. It also features a snare wire system on the bottom head.
Tom-Toms: These drums are usually larger than snare drums and have varying depths (shallow, medium, deep).
Bass Drum: The largest drum in the set, with a significantly larger diameter and depth.

2. Determining the Drum Diameter:

The diameter is the measurement across the widest part of the drum. This is usually the top rim, although the bottom could vary slightly depending on the drum's construction. Always measure the top rim for consistency.

3. Measuring the Drum Depth:

The depth is the distance from the top bearing edge to the bottom bearing edge of the drum. Measure from the inside edge to edge. This measurement is crucial for selecting the correct head depth.

The Measuring Process: Step-by-Step

Now, let's get down to the actual measuring. You'll need a flexible tape measure.

Step 1: Prepare the Drum: Ensure the drum is clean and free of any debris that might interfere with your measurement.

Step 2: Measuring the Diameter: Lay the tape measure across the top bearing edge of the drum, ensuring it goes from one side to the other passing through the center. Read the measurement where the tape meets itself. This is your diameter.

Step 3: Measuring the Depth: Carefully lay the tape measure inside the drum. This measurement is from the top bearing edge to the bottom bearing edge. Make sure the tape measure is positioned along the deepest part of the shell. This is your depth.

Step 4: Recording Your Measurements: Write down both the diameter and depth measurements carefully. These measurements are crucial when ordering replacement drum heads.

Understanding Drum Head Sizes and Terminology

Drum head manufacturers typically use a system that lists the diameter first, followed by the depth. For example, a "12" x 8" tom head" signifies a 12-inch diameter and an 8-inch depth. Always double-check this information against your measurements.

Common Mistakes to Avoid

Using a rigid ruler: A flexible tape measure is essential for accurate measurements, especially when measuring the inside depth.
Measuring from the outside: Always measure the inside diameter and depth for accurate sizing.
Ignoring the depth: Don't underestimate the importance of the depth measurement. This can affect the drum's tone and resonance.
Not double-checking: Always double-check your measurements before ordering replacement heads to ensure accuracy.

Resources and Further Reading

For more in-depth information on drum heads, their types, and materials, you may want to check out resources from reputable manufacturers like Remo, Evans, or Aquarian. Their websites often have detailed guides and explanations.

By following these steps, you can accurately measure your drum heads and ensure you order the correct replacements, leading to a smoother drumming experience. Remember, precise measurement is key to getting the perfect fit and sound for your drums.
