Different Badminton Grip and Weight Types

Question

Over the years I've used many badminton rackets, with a wide variety of code numbering placed at the beginning of the shaft:

G4/3U
G2/2U

Can somebody give me detailed information about the meaning of those codes?

Answer 1

NOTE: There appears to be no universal, consistent standard for these codes as codes for a manufacturer/country may represent opposite meanings compared to another manufacturer/country.

G is in reference to grip sizes.

U is in reference to racket weight.

For a majority₍₁₎ of rackets:

• Grip sizes range from G1, G2, G3, G4, and G5
  • G1 - 3 in (smallest)
  • G2 - 3 1/4 in
  • G3 - 3 1/2 in
  • G4 - 3 3/4 in
  • G5 - 4 in (largest)

In Japan, they range from G2, G3, G4 to G5 where G2 is the biggest size and G5 is the smallest size. In some countries, the opposite applies.

• Racket weight ranges from 1U, 2U, 3U, and 4U
  • 1U - up to 100 grams (heaviest)
  • 4U - at least 70 grams (lightest)
