Want to pick a suitable badminton racket quickly? Here is our 3-minute guide covering practical tips for racket selection for all players.
Have you ever felt confused by 4U, 5U and 6U when shopping for a badminton racket? These common weight markings greatly affect how your racket swings and performs on the court. Today we will explain everything about racket weight standards and help you pick the most suitable one easily.
What Does U Mean? Full Explanation of Racket Weight
U is the standard weight unit for badminton rackets. The larger the U number, the lighter the racket.
- 4U: 80g – 84.9g (Most popular standard weight)
- 5U: 75g – 79.9g (Lightweight for faster swings)
- 6U: 70g – 74.9g (Ultra-light & highly flexible)
In the early days, wooden-handle rackets had inconsistent actual weights due to different wood density. Using U weight ranges provides a unified standard and makes selection much simpler for buyers.
Performance Comparison: 4U vs 5U vs 6U
4U (80g – 84.9g) | Balanced All-Rounder
This is the classic golden weight favored by most players.
Features: Balanced power and flexibility with excellent stability and solid hitting feel.
Advantages: Easy to hit high clears, powerful smashes and supports continuous attacking play.
Best for: Beginners, players with average or above strength, singles players and backcourt attackers.
Recommended models: TERMINO Ox King (4U), Sword of Kings (4U)
5U (75g – 79.9g) | Speed & Defense Focus
Ideal for players who prioritize quick reactions and defensive skills.
Features: Fast swing speed, less strain on wrists and superior control.
Advantages: Delicate net shots, fast drives and blocks; perfect for frontcourt play in doubles.
Best for: Beginners with less strength, doubles lovers, counter-attack players, women and teenagers.
Recommended models: TERMINO Angel A16 (5U), Angel A19 (5U), Solid Color Training Racket (5U)
6U (70g – 74.9g) | Ultra-Light & Agile
It is one of the lightest mainstream racket weights on the market.
Features: Extremely fast swings; requires proper hitting techniques to deliver power.
Advantages: Less fatigue after long play and outstanding performance for net rushing.
Note: A 6U racket with a low balance point (below 290mm) lacks smash power. Some offensive 6U rackets adopt a higher balance point (above 300mm) to enhance smashing performance.
Best for: Female players with low strength, aggressive frontcourt doubles players and teen intermediate players.
Recommended models: TERMINO Zero (72g), N8 (6U)
How to Choose: Based on Body Strength, Playing Style & Skill Level
1. Body Type & Strength
- Adult male beginners: Choose 4U
- Female players or beginners with weak strength: Choose 5U
- Teenagers or players with very low strength: Choose 5U or 6U
2. Playing Style
- Offensive players & singles players: Go for 4U. A balance point over 295mm delivers extra head weight and stronger smashes. Balance point refers to the racket’s center of gravity. Higher values mean a head-heavy racket with better attacking ability.
- All-round doubles players: 5U is the top choice for quick drives and blocks.
- Net rushing players: Pick 6U for lightning-fast swings to catch opponents off guard.
3. Skill Level
- Beginners: Start with 4U or 5U. Too heavy rackets make it hard to generate power, while overly light rackets cause unstable control.
- Intermediate players: Select by playing style. Choose 4U for heavy attacks and 5U for fast continuous attacks.
- Advanced & professional players: Most use 3U or 4U, which requires professional strength training.
Important Tip: The balance point (mm) affects hand feel even more than U weight.
- Balance point above 295mm: Head-heavy, strong attack, weaker defense
- Balance point below 295mm: Head-light, flexible and easy to control
For example, a 4U racket with a 285mm balance point may feel lighter than a 5U racket with a 305mm balance point.
Practical Buying Tips
- Test swing in store: Swing the racket over 50 times to check if your forearm and wrist feel tired.
- Check material: Prioritize full carbon fiber rackets, which are lightweight and elastic. Avoid heavy aluminum rackets.
- Adjust with grip tape: Add thick grip tape to 5U/6U rackets to increase overall weight and reduce unstable swinging.
- Common mistakes to avoid: Do not blindly choose professional 3U rackets. Excess weight leads to incorrect movement and tennis elbow. Do not think lighter is always better. A 6U racket cannot generate powerful smashes without solid hitting techniques.
Final Summary
4U offers solid stability, 5U brings great agility and 6U delivers ultra-fast swings. No weight is absolutely better — the most suitable one is always the best.
New players are suggested to start with 5U and adjust the weight after improving skills. Doubles players can try 5U to enjoy faster swing speed. Players with low strength or technique-focused styles will find the perfect balance between light weight and control from 5U to 6U.
As world champion Zheng Siwei said: When your skills match your equipment, even a standard racket can show great power. Do not worry too much about technical parameters. Trust your body feeling on the court, and you will find your ideal badminton racket.
