The Ultimate Trumpet Mouthpiece Comparison Chart

Note: Please do not take diameter measurements too seriously. Most of the time the difference in columns can be 0.02 of an inch (0.5 mm). Not much really. The measurements are done for comparison purposes of relative sizes. Attributes such as cup depth, rim shape, bite, and backbore also make a big difference in how a mouthpiece plays and feels.

Sizes are approximate since every manufacturer is a little different. Let me know if I have an error (besides rounding) or have missed a manufacturer that doesn't use Bach/Schilke Sizing. Email information to Jim Fox at: DrJAFox@gmail.com
