This article details an experiment designed to determine the weight of 1.25mm synthetic gut tennis strings within a standard 98 square inch tennis racquet. The experiment utilized a precise scale to measure the weight of the strings after carefully removing them from a Technifiber T-Rebound 298 racquet. This meticulous process ensured accurate measurement by first recording the weight of the empty container before adding the strings. The findings offer valuable insights into the weight characteristics of synthetic gut strings, a crucial factor for players seeking to optimize their equipment.The study provides a quantitative measurement of the string weight, offering a practical data point for players and racquet technicians alike. Understanding the weight of string materials is vital for achieving optimal racquet balance and overall playability. The results highlight the surprisingly light weight of synthetic gut, contrasting with heavier options such as polyester. This information contributes to a more nuanced understanding of how string choice influences racquet performance and player comfort.

Weighing the Strings
This experiment aims to determine the weight of synthetic gut tennis strings, specifically a 1.25mm diameter string, strung in a 98 square inch (630 square centimeters) racket head.

A precise scale is used to accurately measure the weight. The strings were previously removed from a Technifiber T-Rebound 298 racket.
The empty container’s weight is first recorded to ensure an accurate measurement. Afterwards, the synthetic gut strings were carefully placed into the box.
The Results
After carefully placing all the strings into the container and re-weighing, the result revealed that the total weight of the strings is surprisingly light.

The total weight of 1.25mm synthetic gut strings from a 98 sq in racket was measured at only 14 grams.
This result is less than anticipated, suggesting that synthetic gut strings are, indeed, lighter than other types of strings, like polyester. The string pattern (16x19) is also a factor to consider
Conclusion
This experiment conclusively shows that the weight of 1.25mm synthetic gut strings in a 98 sq in (630 sq cm) racket is approximately 14 grams.
This is significantly lighter than expected and confirms the generally lighter weight of synthetic gut compared to polyester. The string pattern should always be considered when comparing string weights.
This information is valuable for players looking to optimize their racket weight and balance for enhanced playability and maneuverability.
