Every stringer eventually settles on a handful of tension ranges they reach for by instinct, but new customers and edge cases call for something more structured than gut feel. A clear reference by player type speeds up the conversation and gives players confidence that their setup was chosen deliberately, not guessed at.
Beginner and recreational players
Beginners benefit from the lower end of the manufacturer's recommended range, typically in the 21–23 kg band for a standard frame. Lower tension produces a larger, more forgiving sweet spot and reduces the arm shock from off-center hits, which are frequent at this stage. Comfort and power matter more than control for players who are still developing consistent technique — a string bed that feels dead or harsh will discourage practice rather than support it.
Club and intermediate players
Club players generally land in the 23–25 kg range, with the exact figure shaped by how often they make clean contact and how much spin they generate. This group is the most varied: some want extra control as their swing speed increases, others still need the comfort margin of a beginner setup. Ask about playing frequency and any elbow or wrist sensitivity before defaulting to the middle of the range.
Advanced and competitive players
Advanced players typically sit between 24–27 kg, often paired with polyester or a hybrid setup to manage the added stiffness. At this level, players have the technique to generate their own power, so tension shifts toward control and predictable ball flight rather than free power. Many advanced players also restring more frequently, which allows for tighter tension windows since tension loss between sessions is less of a concern.
Professional and tour-level players
Professional setups vary widely by individual preference, but they frequently sit in a 25–29 kg range, sometimes with differential tension between mains and crosses. At this level, tension is dialed in through extensive personal testing rather than a generic chart — the stringer's job is to maintain exact consistency stringing after stringing, since even small variance is noticeable to a player at this level of feel.
Adjusting for string type and head size
- Polyester strings lose tension faster than multifilament or gut, so many stringers add 1–2 kg above the player's stated preference to compensate for the initial drop
- Larger head sizes (100 sq in and above) generally play looser at a given tension than smaller heads, so a slight increase can restore the expected feel
- Players moving from one string type to another should be told to expect a different feel even at the identical tension number
- Hybrid setups often run the more elastic string a few kilograms tighter than the stiffer string to balance the overall string bed response
Common scenarios that move a player off the chart
- A player switching from a smaller to a larger head size often needs a tension increase of 1–2 kg to recreate the same string bed feel they are used to
- Players recovering from tennis elbow or other arm strain should generally be moved toward the lower end of their range regardless of skill level, even temporarily
- A player who recently changed string type — say, from multifilament to polyester — should expect to need a different number, not the same one carried over
- Tournament players sometimes request a slightly tighter stringing for a specific surface or event, then return to their normal tension afterward
Talking players through a tension change
Most players notice a tension change in the first few minutes of hitting, and many will report the new setup feels "wrong" purely because it differs from what they are used to, not because anything is actually off. Framing the change before they walk on court — what to expect, and why the adjustment was made — heads off most of that confusion. A short note on the work order explaining the reasoning also gives the player something to reference if they come back with questions a week later.
A tension chart is a starting point, not a rule. The goal is a setup the player doesn't think about during a match — and that takes a conversation, not just a number.
