Should You String Natural Gut at a High Tension?
Natural gut does not need a high tension simply because it is expensive. Match its elasticity and tension maintenance to the racquet, swing, and care conditions; price is not a formula for the machine setting.

Start with this check
Natural gut is generally known for high elasticity and relatively good tension maintenance, but it requires care around moisture, friction, kinks, and damaged grommets. At the same reference tension, diameter, coating, full-bed or hybrid construction, and frame pattern can still change stringbed stiffness and wear. Machine-set reference tension is a process record; an app’s estimated current tension and a separate whole-bed stiffness reading describe later condition. A higher number does not simply guarantee longer life or better performance.
Try these steps in order
- Verify the exact recommended range for the racquet and the official handling and storage instructions for the natural gut product. Record the product name, whether it is coated, the actual diameter, and whether it is a full bed or hybrid configuration.
- Before stringing, ask an experienced stringer to inspect for frame cracks, split or sharp grommets, and clamp cleanliness. Confirm the stringer’s natural-gut handling method and experience.
- If you have a previous setup, recover its reference tension, stringer and machine, initial playing response, and usable lifespan. For a new baseline, choose a conservative starting point within manufacturer guidance for the intended purpose; do not raise tension merely because the string is expensive.
- For a hybrid, record the product, diameter, direction, and setting of the mains and crosses separately. Observe friction against the other string and notch locations, and do not assume one fixed tension differential works for every combination.
- At a repeatable elapsed time after stringing, take the baseline measurement while keeping reference tension, estimated current tension, and stringbed stiffness separate. For each session, record cumulative time and launch angle and impact feel, and photograph fraying and notching.
- After use, lightly wipe away moisture and dirt with a dry cloth and store away from extreme temperatures and humidity. If exposed to rain or if coating damage is significant, dry completely and have a professional check the condition and the need for replacement.
Bottom line
Natural gut’s value is not higher tension, but using its elasticity, tension maintenance, and manageable lifespan for the intended purpose. Accurate product, process, and condition records are a better setup guide than price.
