Racket Anatomy — Know the Parts
Before comparing specs, know what you're looking at:
|
Head (Frame) The string-bed frame. Shape and size determine your sweet spot. |
Shaft Thin tube between head and handle. Its stiffness controls power vs. precision. |
|
T-Joint (Cone) Connects shaft to head. Transfers swing energy into the frame. |
Handle & Grip Where you hold it. Grip size (G4–G6) affects wrist control and comfort. |
6 Specs That Define How a Racket Plays
Weight
The U rating (2U–6U)
Heavier = more power. Lighter = more speed and less fatigue.
Balance
Where the weight sits
Head-heavy for smashes. Head-light for speed. Even for all-round.
Shaft Flex
How much it bends
More bend = easier power. Less bend = more precision.
Head Shape
Isometric vs oval
Isometric = bigger sweet spot. Oval = concentrated power.
Grip Size
G4, G5, or G6
Wrong grip strains your wrist. G5 fits most adults.
Singles vs Doubles
Different game, different specs
Singles needs power and mass. Doubles needs speed and agility.
1. Weight — The "U" System
Lower U number = heavier racket. These three cover 90% of players:
Heavy
3U
85–89g unstrung
Power
More mass behind smashes and full-court clears. Tires arm faster.
Best for: Singles attackers, power hitters
Most Popular
4U
80–84g unstrung
All-Round
Balanced power and speed. Used by ~60% of players worldwide.
Best for: Most players, singles and doubles
Light
5U
75–79g unstrung
Speed
Faster swings, quicker reactions at the net, less arm fatigue.
Best for: Doubles, beginners, joint pain
Also available: 2U (90–95g) for rare pro power builds and 6U (<75g) for ultra-light net play. Add ~10g for strings and grip.
2. Balance — Where the Weight Sits
Two rackets can weigh the same but feel completely different. Balance changes everything.
Head-Heavy
>300mm
balance point
Power
Devastating smashes, deep clears. Slower recovery between shots.
Best for: Attacking singles, rear-court, smash-heavy
Even Balance
~295mm
balance point
Versatile
Decent power and decent speed. Adapts to any situation.
Best for: All-rounders, developing style, mixed play
Head-Light
<290mm
balance point
Speed
Fast swings, quick net play, easy defensive returns.
Best for: Doubles front-court, defensive, fast-reflex
Not sure? Start even-balance. Move to head-heavy once your swing is consistent enough to use the extra mass.
3. Shaft Flexibility
The shaft bends during your swing. More flex = more power assist. Less flex = more precision.
Beginner
Flexible
high shaft bend
Forgiving
Catapult effect generates power from slower swings. Tolerates off-centre hits.
Best for: New players, casual, developing technique
Intermediate
Medium
moderate shaft bend
Balanced
Good mix of power assist and shot accuracy. The transition point.
Best for: Club-level, regular competitive players
Advanced
Stiff
minimal shaft bend
Precise
Direct swing-to-shuttle transfer. Demands fast, clean technique.
Best for: Competitive and tournament-level players
Extra Stiff exists for tournament pros — maximum precision but punishes every timing error. Match flex to your current skill, not where you want to be.
4. Head Shape
Two shapes dominate. The difference is the sweet spot.
5. Grip Size
Higher G number = smaller grip. Wrong size strains your wrist and kills control.
Large
G4
~102mm (3.5")
Spacious
More grip area for players with larger hands. Less common in retail.
Best for: Players with larger hands
Standard
G5
~99mm (3.25")
Universal Fit
Default on most rackets. Fits the majority of adult players.
Best for: Most adult players
Small
G6
~96mm (3")
Compact
Smaller circumference allows more wrist movement and finger control.
Best for: Smaller hands, juniors
Pencil test: Hold the racket in your playing grip. You should fit a pencil between fingertips and palm. Fingers touch palm → too small. Finger-width gap → too big. Between sizes? Go smaller + add overgrip.
6. Singles vs Doubles Setup
Your game type changes which specs matter most.
