Matching two racquets: why “the same model” is not enough
Updated: 2 days ago
You break mid-game. You take out the second racquet — same model, bought the same day, same string, same tension. And something is off, without your being able to say what.
That something is measurable. Two frames from the same box can differ by several grams in mass and several points of swingweight. A manufacturer states a nominal value and a production tolerance, not the value of your particular unit.
What the gap costs
Timing. Swingweight decides what a stroke costs. A noticeable gap changes when the head arrives: you correct for it, without knowing, for two games.
Depth. A frame heavier in the head ploughs through more: same footwork, same stroke, different length.
Confidence. That is the real cost. You do not play the same point with a racquet you doubt.
How they are made identical
First the three quantities are measured on each frame — mass, balance, swingweight — then a target is chosen. The heavier frame sets the reference, because mass is added: it is never removed.
After that it is arithmetic and placement. Loading the head raises swingweight, compensating under the grip brings balance back without lowering it again, the buttcap adds mass with almost no effect on swingweight. The formulas and the zones are set out in the weight, balance and swingweight guide.
It ends with a check measurement. A pair announced as matched without a final reading is not matched: it is hoped for.
That dispersion belongs to the retail frame, not to ours. A Matcheur racquet is tuned to order, to the tenth of a gram: two units of the same reference leave the workshop already identical, with no matching to add. Matching exists for the frames you already own.
What matching cannot do
Frame stiffness (RA) and torsional stiffness cannot be adjusted by adding weight. Twistweight can be: it is the frame's inertia about its long axis — its resistance to twisting on an off-centre ball — and it is set by loading at 3 and 9 o'clock. Two frames far apart on those two points will stay two different frames, even at equal mass, balance and swingweight. That is the honest limit of the exercise, and it is better stated before starting than after. It is also why the whole adult range is fixed at 69 RA: two frames from the same range already start from the same point.
When it is worth it
You alternate two racquets within a match, or change racquet at every ball change.
You play multi-day tournaments, where breaking a string is not a hypothesis but a schedule.
You have just had a frame repaired and you want it to find its twin again, to the gram.
In all three cases, matching is ordered online on the ProSetup tuning page: both frames are measured, brought to the same target, and you leave with the record of the values, before and after.
Both racquets are sent to our workshop, in Normandy; shipping details are given to you when you order. Allow two weeks.
Matching does not win matches. It removes one variable — the one that makes a racquet answer differently from another without anyone knowing why. You will only notice it the day you change racquet without thinking about it.
