What do the numbers and letters on drumsticks mean?
Drumstick sizes and weights are often represented by an alphanumeric code: “5A,” “5B,” “7A,” “2B,” and so on. Lower numbers mean thicker sticks (similar to cable gauges). Higher letter values indicate a heavier weight class: “A” being lighter duty, “B” being heavier duty.
This naming convention was established by William F. Ludwig in the mid-20th century. Though far from standardized, the underlying principles remain: “A” represents thinner orchestral sticks, “B” indicates chunkier sticks suitable for live band settings, and “S” denotes heavyweight street or marching sticks.
