Excuse my ignorance, but what is the meaning of L3 or L4 on the frame of a racquet?
Thank you

size of the grip, L3 is 4 3/8 and L4 is 4 1/2

Yeah, it refers to grip sizes. Each size up is a 1/8 inch increase. So L1= 4 1/8, L2 = 4 2/8 = 4 1/4, L3 = 4 3/8, L4 = 4 4/8 = 4 1/2, etc.

I believe L3 or L4 is the swing index for Head racquets. L4 rated racquets require longer swing than an L3.

I believe Head set it up so that for the longest swing, you can use racquets with L6 rating (Head Prestige Series) and for the shortest swings you would use S12 rated racquets.

It's L6 -> L5 -> L4 -> L3 -> L2 -> L1 -> S1 -> S2 -> . . . -> S12.

Hope that helps.

Well, do you use a Head racquet? And where do you see the L3?

Ah, that seems to be an internal code for Head racquets!
Got it!

My old Donnay Pro One also has a sticker that reads L4. I can't tell whether it refers to the grip or the swing rating.

Well L1-L5 refers to grip sizes but unfortunately Head was stupid enough to use this system to give information about the swing style needed to wield particular Head racquets...

On all racquets when you see L1, L2, L3 and so on symbols it refers to grip sizes, usually there also is the second system and that's e.g. 4 3/8 (L3) but when you see let's say L4 on a Head site it refers to swing style that fits a racquet...

I think it's a carryover from wooden racket days.

Rackets came in light, medium, and heavy weights. Anything under 12.5 oz was considered light.

As for the numbers it was in 1/4 in. increments from 4 inches gripsize. 1 for 4" up to 7 for 4 7/8".
