Babolat Boost Aero tennis racket - strung

Light (up to 285 g) – easy to maneuver, ideal for beginners and those who value fast play. Most often chosen by women, young people, and players with less physical strength.
Medium (286–305 g) – provides a good balance between power, control, and maneuverability. Suitable for both men and women at intermediate and advanced levels.
Heavy (over 305 g) – offers the greatest stability and hitting power, but requires good technique and fitness. Most often chosen by men and advanced players, although stronger and more advanced women also use it.

Open (e.g., 16x18, 16x19) – larger gaps between strings make it easier to generate spin and power. The ball "sinks" into the strings more easily, allowing for greater topspin and a higher shot trajectory. Very popular in rackets designed for modern, dynamic play.
Intermediate (e.g., 16x20) – provides a compromise between ease of spin generation and shot control and predictability. A good choice for players looking for a versatile racket characteristic.
Dense (e.g., 18x20) – smaller gaps between strings provide greater control and precision. This pattern usually generates less spin and free power, which is why it is often chosen by experienced players who hit hard and expect high racket predictability.

Aluminum – a material used mainly in recreational and junior rackets. Aluminum rackets are affordable and easy to use, but provide less stability, control, and feel than graphite constructions.
Graphite composite – a construction using a combination of several materials, most often aluminum and graphite. Provides better stability and playing properties than basic aluminum rackets, remaining a good solution for beginners and recreational players.
Graphite – the best choice for people who want to play regularly, develop their technique, and make faster progress. The graphite construction provides better stability, ball feel, control, and a more predictable racket response, making it easier to learn proper strokes and further develop the game. A graphite racket can serve a player for a longer period – from the first training sessions to a much higher skill level. This is the most recommended type of construction for people who treat tennis as a regular hobby or sport.

Beginner – rackets primarily focused on ease of play, high error tolerance, and easy power generation. They are usually lighter and often have a larger head, which helps during the learning of proper technique.
Intermediate – rackets offering a good balance between power, control, comfort, and maneuverability. Designed for people who play tennis regularly and have already mastered the basic techniques.
Advanced – models offering greater precision, stability, and control. They usually require better technique and the ability to generate power independently. They allow for more conscious control of the ball's direction, pace, and spin.
