Sources
Almost every number comes from the Tennis Warehouse University racquet comparison database, pulled 26 September 2026, which holds the TWU lab's strung measurements for each frame. The index uses the ten fields it holds, which are head size, length, weight, balance, swingweight, flex, twistweight, vibration frequency, power and sweet zone. Details that other sites list for some frames but not all, such as string pattern, beam width and unstrung weight, are left out so every frame is compared on the same footing.
The Wilson Defyer range, released in July and August 2026, is not in TWU's database yet. Its head size, length, strung weight, balance, swingweight and stiffness come from the Tennis Warehouse Europe product pages, which list Tennis Warehouse's own strung measurements. Its twistweight, vibration frequency, power and sweet zone are left blank until TWU tests it, so the Defyer drops out of any chart, filter or play profile axis that needs them.
Materials and pros
The materials and the pros using each frame come from its Tennis Warehouse product page, or Tennis Warehouse Europe where the US page has gone, exactly as listed there. They appear only in the Differences cards and never feed the numbers, classes or filters. Frames with no product page on either site show neither, rather than borrowing from a sibling model. That applies to 18 frames, including the Percept, Pro Staff v14 and TFight ISO lines.
Which frames
Every racquet from the nine brands that TWU marks as current, newest generation of each line, released from 2023 onward, with its Team, Lite, Plus, Tour and weight variants. Names are TWU's own, including the year or version where TWU gives one. The Prince O3 Legacy 120 is left out on purpose, as a 120 in² frame far outside the rest of the index.
Racquet or racket
The same thing, spelt two ways. Tennis Warehouse uses racquet, so the index does too.
Gaps
A few current frames are not in TWU's database yet, for example the Wilson Ultra 100 v5, the Head Boom 2026 and the Tecnifibre TF40 2024. They are left out for now and will join when TWU adds them. The Defyer range is the one exception, covered under Sources. Two TWU entries carry an obvious typo that is corrected here. "Pure Stike 98 18x20" reads as Pure Strike, and the Phantom 100X 305g 2024 is listed at 23 in long, shown as 27 in like every other Phantom 100X.
Conversions
Balance points = (length ÷ 2 − balance in inches) × 8, from TWU's strung balance in centimetres. One point is 1/8 in, about 3.2 mm. Negative points are head-heavy (HH). Ounces and square centimetres are straight unit conversions.
Play profile
Each axis runs from 0, the lowest frame in the index, to 100, the highest. Power is TWU’s power rating, stiffness its RDC flex and forgiveness the average of sweet zone and twistweight. TWU does not measure control or spin, so both are estimates built from its lab specs. Control is the reverse of power and head size. Spin favours a bigger head and a lower swingweight, which give the strings more room to move and the racquet more speed. String pattern matters for spin too, but TWU does not list it for every frame, so it is left out. The dashed shape is the median frame. A frame TWU has not tested yet, such as the Defyer, only shows the axes its specs cover. Control and spin can also be picked as axes on the map.
Racquet finder
The finder is optional and turns each answer into a target. How long you have played sets the range for strung weight, swingweight and head size, drawing on Tennis Warehouse's swingweight bands (low at 305 and below, medium 310 to 325, high 325 and up) and the usual advice of bigger heads for newer players. Swing length moves the target for TWU's power rating. Shot shape uses the spin or control estimate. Court position adjusts balance, twistweight and swingweight. Arm trouble caps stiffness at 66 RDC, the limit Tennis Warehouse suggests for sore arms, or 64 when it hurts now, and steers away from very light frames. The preferred feel shifts the weight range up or down.
Each frame loses points for every spec outside its target, and the three best come from different racquet lines so the shortlist offers real alternatives. Starting from your own racquet works the same way, with its specs as the target, moved in the directions you choose. Grip size and strings are not part of it, so treat the result as a shortlist to demo.
Classes
Weight classes use strung weight, running Ultralight under 290 g, Light 290 to 305 g, Standard 306 to 320 g, Tour 321 to 330 g and Heavy over 330 g. Swingweight bands follow Tennis Warehouse's buying guide, with low below about 310, medium 310 to 325 and high above 325. Stiffness bands follow the grades on its lab sheets, with 63 and below low, 64 to 66 medium and 67 and up high. Head sizes follow the usual mid, midplus and oversize split. Twistweight, vibration, power and sweet zone are split into rough thirds of this index.
Tolerances
Frames vary between production runs, so no two of a model are identical. Wilson, for example, quotes ±5 g weight, ±7.5 mm balance and ±10 swingweight for the Ultra 100 v5. Treat a gap of two or three swingweight points as noise.
Drawings
Each head is drawn as an oval with the frame's head area, and the tinted zone inside it has the area of TWU's sweet zone, left out where TWU has not measured one. Length and balance point are to scale. The outline is not traced from the mould.
