Get to know your racket – the Mantis way.
Choosing the right tennis racket can feel overwhelming—especially with all the technical terms and numbers involved. But understanding the specifications isn't just for the pros. At Mantis, we believe every player deserves to feel confident about the gear they use.
Let’s break down the key racket specs and what they really mean for your game.
🎯 Head Size
Measured in square inches (sq. in.)
This refers to the total surface area of the racket’s head—basically the part with the strings. Larger head sizes offer more forgiveness and power thanks to the trampoline effect, while smaller heads provide more control for players who can consistently hit the sweet spot.
- Over 100 sq. in. – Power-focused, more forgiving
- 96–100 sq. in. – Balanced, versatile
- Below 96 sq. in. – Precision and control
Mantis Tip:
New to the game or looking for help generating power? Go bigger. More experienced with a long, fast swing? A smaller head may give you the control you’re after.
Mantis racket head sizes:
- Pro series = 98 sq in
- PS Series = 100 sq in
⚖️ Weight
Measured in grams (g) or ounces (oz)
The total mass of your racket plays a big role in how it feels and performs.
- Light (<285g / 10oz) – Easier to swing, less tiring
- Medium (~300g / 10.6oz) – A great all-rounder
- Heavy (>310g / 11oz) – More stable, more power potential
Mantis Tip:
Heavier rackets deliver more punch but require good technique. Beginners often prefer lighter options for better maneuverability.
Mantis racket weights:
- Pro 310 = 310g
- Pro 295 = 295g
- PS 300 = 300g
- PS 285 = 285g
🎾 String Pattern
Shown as something like 16x19 or 18x20
This describes how the strings are arranged with the first number referring to the number of strings running vertically through the frame and the second number referring to the strings running horizontally across the frame:
- 16x19 – Open pattern for more spin and power
- 16x18 – Even more open for aggressive topspin
- 18x20 – Tighter for precision and control
Mantis Tip:
Unless you have a strong preference, start with 16x19—it offers a great balance of control, feel, and spin.

🧭 Balance Point
Measured in millimeters (mm)
Balance determines where the weight is distributed—toward the head, the handle, or evenly.
- Head-Heavy (>345mm) – More power, great for baseline play
- Head-Light (<345mm) – Better control and faster reaction at the net
- Even Balance (~345mm) – A good mix of both
Mantis Tip:
Looking for more stability on groundstrokes? Go head-heavy. Want precision and quick handling? Head-light could be your best bet.
Mantis rackets balance points:
Both our models and all weights: 325mm
🧱 Beam Width
Measured in mm (e.g. 23/26/23mm)
This is the thickness of the frame at different points. Wider beams typically generate more power due to added stiffness.
With straight beam rackets (like the Mantis Pro series) the beam width will be the same throughout the racket whereas with tapered beam rackets (like the Mantis PS Series) the beam width changes across the length of the racket
- <22mm – Thin beam, control-oriented
- 22–24mm – Balanced performance
- >24mm – Thick beam, power-friendly
Mantis Tip:
Beginners and power-seekers: go wider. Control players: look for thinner beams for better feedback.
Mantis racket beam widths:
- Pro Series: 21mm
- PS Series: 23.5mm / 25mm / 22.5mm
📏 Length
Standard: 27 inches (686mm)
While most adult rackets are 27 inches long, some extended-length models (27.5–28 inches) exist to give players more reach and power.
Mantis Tip:
Stick with standard unless you’re looking for extra leverage on serve or groundstrokes.
All Mantis rackets are 27 inches in length
🔧 Recommended String Tension
Measured in pounds (lbs)
Each racket has a recommended tension range. Higher tension = more control; lower tension = more power. Always string within the manufacturer’s suggested range to preserve frame integrity.
Mantis Tip:
Experiment within the range to find what feels best for your style of play.
All Mantis tennis rackets have a recommended string tension of 44 – 60 lbs
The Bottom Line:
There’s no perfect spec—only the perfect match for you. At Mantis, we design rackets that blend precision, innovation, and feel so players of all levels can find their edge.
