Best tennis strings fordurability

You are snapping strings too often. Every one of 720 currently-produced strings carrying the measurements this ranking needs was scored against it — these are the 15 that came out on top, capped at two per brand so gauge variants of one string cannot fill the list.

The same ranking, without polyester

15 of the 15 above are polyester, which is an honest result and an unhelpful page — it wins this ranking outright and costs several times what anything else does. Ruled out before scoring rather than penalised during it, so the fit percentages below stay honest about what is left.

What "durability" is actually ranked on

The database publishes no durability figure, so this is scored on proxies: thickness, low string-on-string friction — sawing at the crossings is what actually severs a main — and material, because polyester genuinely outlasts nylon in a way these numbers cannot express.

This is the weakest ranking on the site — the database publishes no durability figure at all, so it is scored on proxies. Treat it as a shortlist, not a verdict.

Each string is scored on where it sits in the database on each measurement above, never on an absolute figure, so the ranking is always relative to what actually exists. How these numbers are made →

Make this specific to your racquet

This page ranks the database on the need alone. String pattern, head size and frame stiffness each move the answer, and a stiff frame removes the firmest quarter of the database outright rather than merely ranking it down — the finder applies all of that and shows you which picks changed as a result.
