How to Choose a Timpani Head

Choosing the size of a symphonic timpani head is not the same as for other drums. When buying a head for your 26" timpani, logic would suggest that you need a 26" head, right?

Symphonic timpani, unlike other drums, use a different method to determine the proper head size. Timpani heads are larger in diameter than the bowl size, so you need a head that exceeds the actual size of the drum. Therefore, knowing how far the head extends over the bowl is crucial.

There are basically two manufacturers of synthetic timpani heads: Remo and Evans. Both make high-quality heads that fit nearly all timpani.

If you’re lucky enough to still have the label or reference number on your timpani head, you can simply order the same model. But often that’s not the case, so we’ve included charts below provided by Remo and Evans to help you select the right model.

REGULAR COLLAR OR EXTENDED COLLAR?

Regular Collar

If there is little or no space between the edge of the bowl and the collar, you have what’s known as a regular collar timpani. These timpani were generally made before 1978. Determining the actual size can be tricky.

Before 1978, manufacturers made timpani in many sizes (20", 23", 25", 26", 27", 28", 29", 30").

A good rule of thumb:

• Add 1 inch to the size of the drum to find the correct head size.
• Exception: 23" timpani require a 24 1/4" head.

Extended Collar

If your timpani were made after 1978, manufacturers started to standardize sizes, making it much easier to determine the correct head size.

You’ll notice a ~2" (5 cm) gap between the bowl edge and the collar (diagram 2). This is called an extended collar timpani.

For this type of timpani, you should add 2 inches to the size of the drum.

• 26" timpani → 28" head
• 29" timpani → 31" head, and so on

Exceptions: High-end models such as:

• Adams Philharmonic
• Walter Lights
• Yamaha 9000
• Premier also differs from the standard

Another Way to Determine the Correct Size

Remove the head from the bowl and measure the outside diameter — from one edge of the metal collar to the opposite side.

Helpful Tip

Once you've purchased the correct head, write the model code and size on the head with a permanent marker. This will save you trouble in the future.
