String-Bed StiffnessHead SizeString Pattern

Why Does the Same 50 lb Feel Different Between Racquets?

The same machine setting does not produce the same finished string-bed firmness in every racquet.

Player overview

Head size, string length, pattern density, material, gauge, and stringing method all contribute to string-bed stiffness.

Measurement guide

  1. Compare the two racquets' head sizes, patterns, strings, and gauges side by side.
  2. Under matching conditions, record the post-stringing measurement and first-hit feel.
  3. Do not copy one racquet's number; build a repeatable baseline within each racquet.

Latest measurement

The useful unit of comparison is the racquet-and-string system, not the tension number alone.
