Head Boom Junior 2026 Tennis Racket

• endorsed by L. Musetti, C. Gauff

Explosive power is combined with the touch to play delicate drop shots in the BOOM JR.

Ambitious juniors aged from 9 to 11 can play modern tennis with a racket that has been enhanced with the introduction of Hy-Bor, a state-of-the-art material mix that is mainly used in the high-tech aerospace industry. Adding that material to the shaft has improved the racket’s perceived stability and power.

Endorsed by Coco Gauff and Lorenzo Musetti, this model has a construction that is based on the adult rackets BOOM MP L and BOOM MP, with smaller dimensions to suit up-and-coming juniors. With the power, confidence and fun that comes from playing with the BOOM JR, juniors don’t have to think about anything else but enjoying the moment and hitting their next shot. Like the adult BOOM frames, the BOOM JR comes in a vibrant blue design inspired by HEAD’s iconic ski racing collection. This racket will help kids to feel good about themselves and their tennis.

Facts:

Age: 9 to 11

Specifications:

Weight = Highweight (245 g / 8.6 oz): Higher weight rackets are designed for kids aged 8-10 (25 inch) and 9-11 (26 inch). They offer young players more control and stability and require more strength than lower-weight rackets.

Balance = Even Balanced (320 mm / 0.4 in HL): This racket offers a balanced feel, providing a mix of control and power. It’s perfect for young players as they grow their skills, making the game easier and more fun.

Head size = Junior Large (645 cm² / 100 in²): With a larger head size, these rackets provide more power and a bigger sweet spot. Ideal for kids aged 8-10 (25-inch) and 9-11 (26-inch), they help young players hit the ball with more ease and confidence while developing their skills.

String Pattern = Power & Spin (16/19): The 16×19 string pattern, with 16 main and 19 cross strings, is more open, allowing for greater spin and power. The wider spacing between the strings enables the ball to sink deeper, creating more power and responsiveness, making it ideal for aggressive baseline players who rely on spin and speed.

Beam = 26 inch (24 mm): Perfect for kids aged 9–11, 26-inch rackets are lightweight, easy to handle, and slightly shorter than adult rackets—helping young players develop control, power, and confidence as they grow into the game.
