Badminton Racket 3u vs 4u – Which one Should You Choose?

In badminton, your choice of equipment matters a lot. For that reason, players take a keen interest in choosing the best badminton shuttlecocks, rackets, and even shoes.

However, there are some things that you may assume as little. But eventually, these little things separate the professionals from the inexperienced players.

For example, do you know that the choice between badminton grip size g4 vs g5 can affect your game? And likewise, you need to choose carefully between the common badminton racket weights 3u and 4u.

So What Does Badminton Racket 3u or 4u Mean?

So What Does Badminton Racket 3u or 4u Mean

Most leading badminton brands use a number followed by U to denote the weight of a racquet. Note that it refers to the dead weight of the equipment (unstrung). A standard badminton racket should weigh between 80 to 100 grams

And the weight distribution differs from brand to brand. For example, according to Yonex;

1u- 95 to 100g

2u – 90 to 94g

3u – 85 to 89g

4u – 80 to 84g

Most players prefer 3u or 4u. As you may have realized, the higher the number adjacent to U, the lighter the racket.

Badminton Racket 3u vs 4u – Comparison in Performance

From the information given before, you can realize that the difference between 3u and 4u badminton rackets is about 5 grams only.

Though it may seem insignificant, it brings about a crucial difference in performance.

Take, for instance, two badminton racquets of the same brand and balance of head heavy weight distribution. Assume one has a weight of 3u and the other 4u. The additional 5g weight produces a significant difference in the frame weight.

From that argument, the difference comes out as follows;

Supination vs Pronation

Supination vs Pronation

3u and 4u rackets register different feelings during upward (supination) and downward (pronation) strokes.

The 3u racket feels heavier than the 4u. Accordingly, the extra weight in 3u boosts its downward stroke movement. That makes it ideal for a clear or smash shot.

But during the backhand stroke, the extra weight of 3u works against the swiftness of the wrist. Hence in supination (upward), 4u wins, and in pronation (downward), 3u wins.

Ease to Maneuver

The weight difference also brings about significant change in racquet maneuvering; one of the vital badminton skills in any game.

Assuming other features as the same, the lighter 4u rackets require less effort to maneuver and defend a shot. On the other hand, the heavier 3u racquet would require slightly more power to produce the same swing as the lighter one.

When you compare the badminton singles and doubles, you’ll realize that doubles display higher speed and more shots to defend.

With that said, when looking for the best badminton racquets for badminton doubles, 4u wins. The lightness produces swift maneuvers and ease of defending shots. A heavier racket in a doubles game may tire you prematurely.

On the contrary, in singles, the stability and feel of the racquet become the core issues. In that case, 3u rackets become ideal.


Awful badminton games[worst badminton games] often result from a poor choice of rackets and inadequate skills. The difference between the 3u and 4u badminton rackets is hence vital. And after choosing good equipment, work on the core badminton skills and watch your performance grow with time.
