SharedResource.RacketpediaJoinNow.el-GRHead size (also known as the “string bed” or “oval”) is one of the most important characteristics of a tennis racket, as it directly affects power, control, forgiveness, and comfort.
It’s the area of the frame where the strings are interlaced, measured in square inches (in²) or square centimeters (cm²). The most common sizes range from around 85 in² (550 cm²) to 135 in² (870 cm²).
| Category | Size (in²) | Key Characteristics |
|---|---|---|
| Mid | < 95 in² | Highly precise, low forgiveness, requires more physical effort |
| Midplus | 95–105 in² | Great balance between control and power |
| Oversize | 106–115 in² | More power and comfort, greater forgiveness on off-center hits |
| Super Oversize | > 115 in² | Maximum surface area, ideal for beginners or those seeking ease of use |
A larger head size means a larger sweetspot, making the racket more forgiving on off-center shots.
A smaller head size offers greater precision and responsiveness, but demands better technique and clean contact.
Some manufacturers use a head shape called isometric, which differs from the traditional oval design. The isometric head has a more squared profile, with the upper and lateral parts slightly expanded, which helps increase the sweetspot.
At the same total surface area, an isometric racket offers more effective hitting area compared to a standard oval shape, improving forgiveness and consistency on off-center hits. This design is especially appreciated by players seeking a blend of precision, power, and comfort without increasing overall head size.
String pattern is a key technical parameter that affects control, spin, string durability, and impact feel.
It’s the arrangement of vertical (main) and horizontal (cross) strings in the racquet’s head.
| Pattern | Description | Main Features |
|---|---|---|
| 16x19 | 16 main strings, 19 cross strings | More spin, lively feel, less control |
| 18x20 | 18 main strings, 20 cross strings | More control, solid and stable impact |
| 16x18 / 16x20 | Intermediate variants | Balanced spin and control |
| Open pattern (e.g., 14x18) | Wider spacing between strings | Maximum spin and comfort, but faster string wear |
If you're a spin player or want more power and effect, go with an open pattern. If you prefer precision and consistency from the baseline, a denser pattern is often better suited.
