# weight difference: 16 gauge vs 17 gauge strings?

I recently purchased 2 of the same racquets online (evidently the last 2 racquets they had in stock for now) and according to the rep, there's 2 grams difference between the 2 racquets (he weighed it while over the phone). I'm pretty anal about getting the weight as close to as possible and figured this was close enough. So I asked them to string with a 16 gauge and 17 gauge strings and after receiving them in the mail today, I weighed them myself and now there's a 7 gram difference. Does 16 gauge add that much more weight (5 more grams) to the racquet? This sounded too much to me. I figured a 16 gauge vs 17 gauge would be more like a 1-2 gram difference, not 5. I don't know if they lied to me to sell me in order to sell the racquets or if there really is this large difference in the gauge weights. What do you guys think?

The racquets will be different weights. Using different scales may produce slightly different results. A thicker string will obviously weigh slightly more than the same string in a thinner gauge though it wouldn't be a 5g difference. I'm sure someone more mathematically minded that me could work out the mass difference between two cylinders with a diameter difference of say 5% or whatever the difference is between your two strings.

you wouldve been better off adding 2 grams of lead to the lighter racquet with the same string. Anyways, 5 grams is virtually nothing....

play with both of them and just see which one of them feels better, and try to match the other to that one.

but dont be anal.

5 Sounds a bit too much, but this number will vary depending on the specific string. The denser the particular string, the bigger the difference between the gauges.

I've measured as much as 10g difference between different strings before, not the same string though. So 5 is possible just not likely.

I try not to be anal (hence I gave myself a 2g variability) but hey @ \$200 a pop, I figured I can be a little demanding. i actually already know which one will feel better, in fact, feel perfectly (the lighter one) cuz it's exactly the same weight as the one I demo'ed. And there's nothing like breaking a string then picking up the second racquet knowing that it doesn't swing quite the same. I've had this happen with my older racquets which I've tried to match the weight difference by leading up - without much success. Though I've gotten it close to each other I could always feel a difference b/w the 2. Oh well. Sucks but I will have to return one and have them send me a new one when it comes in stock again.

Thanks for making me feel like I'm not crazy. 10g difference is crazy though. Do you remember what strings they were?

5 grams is 10 inches of standard 1/2" wide lead tape. Put that at 3 & 9 on your racquet head and tell me it does not make much difference!

Switching one guage of the same string material will change head weight by about 2 grams or 4" of lead tape. Even that is a significant weight change for racquets that are matched for weight and balance.

I think it was 17g fibergel power and some 16g poly, maybe Competition. Not sure. The fibergel power is really light and stretchy so when it strung up you don't use nearly as much string, and it gets pretty thin.

It was very obvious which frame was heavier. I said 10g, but it may have been 8g. It was a while ago. But no you're not crazy. I can tell the difference in swing weight between 17g and 16g poly most of the time. Of course it helps that my frame is very head light.

I think between 16 and 17 gauge maybe only 2-3gr difference.

This is an old thread but my stringer put in 17 gauge instead of 16 and it's driving me nuts so I did the calculations:

16 gauge = 1.651 diameter, 17 gauge = 1.473 diameter (millimeters).
Area (16) = 2.59 sq mm, Area (17) = 2.31 sq mm, delta = 0.28 sq mm
% delta = 0.28 sq mm / 2.59 sq mm = 11
11% x 20 grams (string weight) = 2.2 grams which seems to agree with estimates here.

BTW, my fix will be to replace the strings with what I normally use. Adding lead is somewhat of a solution though there are some other characteristics of the string that I miss.
