Tennis racket head size: 98, 100 and 102 sq in compared
TenisRaketi Editör Ekibi · Updated October 2026
Short answer
A bigger head gives a larger sweet spot and more power; a smaller head gives more control but less room for error. For most players 98–102 sq in (632–658 cm²) is the right range, and beginners should look at 100–105 sq in.
In this guide
Head size is the area of the racket's strung face. It is usually given in square inches (sq in), and in Europe also in cm². 1 sq in is about 6.45 cm². You will see a value like "100 sq in" or "645 cm²" on the box or the frame.
Head size chart
Class | sq in | cm² | Sweet spot | Best for |
|---|---|---|---|---|
Midsize | 85–97 | 548–626 | Small | Advanced players who hit the centre every time and want control |
Midplus | 98–104 | 632–671 | Medium | Most club players |
Oversize | 105–115 | 677–742 | Large | Beginners, short swingers, anyone who wants easy power |

If you are torn between several rackets, the Racket Finder looks at your level and style in a few questions, weighs head size together with 6 other measurements and narrows it down to the 3 best fits.
What head size changes
Sweet spot: The bigger the head, the bigger the sweet spot. When you hit away from the centre, a big-headed racket twists less and keeps the ball going where it should. A small-headed racket punishes a miss more.
Power: A big head gives more power. The strung area is wider, so it flexes more at contact and launches the ball more easily. A small-headed racket gets its power from your swing.
Control: A small head makes the ball's path more predictable. To use that you need to hit the centre consistently.
Spin: Head size alone does not decide spin; the string pattern (16×19, 18×20) and the string itself matter more. Big-headed rackets usually come with an open pattern like 16×19, which makes spin easier.
Manoeuvrability: A big head catches more air and swings slightly slower. The difference is small, but you can feel it on quick volleys and recoveries.
Recommendation by level
- You have never played or have played a few months: 100–105 sq in (645–677 cm²). Even when you miss the centre you stay in the point.
- You have played more than a year and hit regularly: 98–102 sq in (632–658 cm²). A balance of power and control.
- You play tournaments and swing long and fast: 95–100 sq in (613–645 cm²). If you can hit the centre you gain control.
- Your arm hurts: A bigger head helps because the racket twists less on off-centre hits. The real cause of the pain may still be stiffness and grip size; see the tennis elbow guide.
Head size does not decide on its own
Two rackets with the same head size can feel very different. Weight, balance, stiffness and string pattern work together. A 100 sq in racket that is light and flexible is very easy; one that is heavy and stiff is much harder. So read head size together with the other measurements: the guide to choosing a racket and the weight and balance guide.
Common mistakes
- Buying a pro's racket. Most pros use 95–100 sq in and heavy rackets; these punish players who do not hit the centre.
- Staying with a big head at an advanced level because "big heads are for beginners". As your game improves, control matters more.
- Treating head size as the only measurement. Put rackets of the same size side by side on the compare page and look at the other measurements.
Frequently asked questions
Should I choose 100 or 98 sq in?
The difference is small but you can feel it. 100 sq in gives slightly more forgiveness and power, 98 sq in slightly more control. If you are consistent in hitting the centre choose 98; if you want more forgiveness, 100.
What head size should a beginner choose?
100–105 sq in (645–677 cm²). The large sweet spot forgives misses and gives easy power.
Does a big-headed racket tire the arm?
Usually not. A big head reduces twisting on off-centre hits, so less shock reaches the arm. Stiffness, weight and grip size matter more.
Does head size affect spin?
Indirectly. String pattern and string material decide spin more. Big-headed rackets usually come with an open pattern, which makes spin easier.
