If you want to see how your Bach compares to other Wedge models find your mouthpiece the table below.
If your Bach mouthpiece appears more than once in the table it is in between Wedge sizes. Most players will play better on the smaller option.
Wedge rim diameters are measured at .04 inches down from the highest point of the rim. Bach measures at a different point. Dimensions listed are therefore different than specs listed by Bach for their mouthpieces.
If you are not confident you are playing your ideal size, or if you are having a specific issue with your playing, visit our Trumpet Fitting Guide.
