Pad Specifications & Thickness Guide

Choosing the correct pad involves more than selecting a general category such as thin, medium or thick. Exact measurements can make it easier to compare pads, identify suitable replacements and achieve the proper fit.

This guide provides Ferree’s pad thickness specifications in both metric and imperial measurements. It is a practical reference for musicians, educators, schools, instrument repair students and experienced technicians.

  • Pad Thickness Reference Chart

    Use the chart below to compare each pad category in millimeters and inches. Individual products may vary slightly, so review the specifications on the product page before ordering.

  • Understanding Pad Thickness

    Pad descriptions such as thin, medium-thin, medium, medium-thick and thick provide a helpful starting point, but the exact measurement offers greater accuracy. Always consider the instrument, key-cup depth, original pad thickness and installation requirements before choosing a replacement.
