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
- Compare the two racquets' head sizes, patterns, strings, and gauges side by side.
- Under matching conditions, record the post-stringing measurement and first-hit feel.
- 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.
