View Full Version : String size, cause I was curious

10-19-2009, 02:48 PM
So I picked up a used racquet that was already strung. The seller told me what was in it, but I wasn't familiar with those strings so for the heck of it, I broke out the calipers (Sorry, mine are inch) and measured each string at 10 random spots:

Wilson Kgut 17: .44 to .50 Mains
TCS17: .46 to .47 X's

Then I measured what I have packages of:

Gamma Syngut 18: .45 to .46
Black code 17: .48 to .50 (All measurements were .50 except the one .48)
Black Magic 16: .50 to .50
Spin X 16: .49 to .51
Hollow core 16: .51 to .52
Gosen 15L: .53 to .54

So all in all, there were 2 surprises: Black Code 17 was the same as all the 16g strings in my bag (how exactly would one measure a hex string anyway?), and the TNT2 18 seems to be only marginally smaller than the 17g strings.

Also intersting to see the mains in the strung racquet varies quite a bit whereas the cross did not. So I measured another racquet:

Black Code 17 mains at 57 lbs and 4 hours: .48 to .49
Gosen 15L x's at 55lbs and 4 hours: .51 to .52

So compared to the string in the package, the black code hardly changed size, but the gosen seems to have "streached" down a bit.

In the end, I'm wondering how marketing is affecting the "size" of a string....??? especially in the case of the black code 17g.
