Some math here! (Comparing grip size)
My short story:
I'm going to get a Victor BS LYD (G2), because there's no G3 available there.
Here, the measures (by victorsport.com.tw):
The question is: What are these 8.1cm? surface cm2? If so and if the grip would be completely round we could calculate the radius:
G2: 8.1 / π (Pi) -> √ = 1.60571cm
G3: 8.5 / π (Pi) -> √ = 1.64488cm
Therefore, the average length is:
G2: 1.60571cm * 2 = 3.21142cm
G3: 1.64488cm * 2 = 3.28976cm
That means the difference (relating to the radius) is around 0,40mm
Therefore I need a overgrip with 1(!)mm thickness for a Victor G2 if my overgrips with 0,6mm matched well to my rackets with G3 well.
Well... I really doubt that my calculations are correct. Maybe they are correct calculated but are nonsense, because I'm still not sure what these 8.1 / 8.5cm are

Lol. What am I calculating for. There's also an english explanation:
"G"is the unit of grip diameter. G1 stands for 7.9cm, G2 stands for 8.1cm, and G3 stands for 8.5cm.
That means: radius (G2) 4.05cm vs (G3) 4.25cm
That also means 0,2cm or 2mm difference between G2 and G3!
Conclusion: If I'm used to 0,6mm with a G3 racket (= 4,25 + 0,6 = 4,85cm) I have to get a 0,8mm overgrip if I'm going to get a G2 racket (4,05 + 0,8 = 4,85cm)
Could someone reply to this and confirm my calculations?

So 5.45-4.05=1.4 => 0.7mm overgrip (0.75mm at least are available)

Lol, yes. Simple, but effective! That's a very good idea to overlap! *facepalm about myself* Why didn't this variant cross my mind?!
Usually I overlap the overgrip as less as possible. Surely it's not possible to do an overgrip completely flat due the minimal overlaps I have on the overgrip. But eventhough there are some tiny "hills" I'd say my overgrip makes the grip 0,6mm thicker.
BUT! Wait, wait, wait...!
The grip has a radius of 4cm and more? LOL, that's not possible. Look at your yardstick (measuring tool). There's no way that the grip has a radius of ca. 4cm!
Damn... I really wanna finish this calculation o_O" Eventhough the 50% overlap is a great idea.
And: 0,6mm (milimeters!!!) or 0,8 -> there's almost no (visible) difference. Can these declarations be real? I also can't imagine that there's a real feeling difference between 0,6mm and 0,8mm. These milimeters, guys!
I'm confused... :S

u must be a engineer.... count down even to the micro milimetre
i seriously just wrap until the feel i like...
usually i use have G5 racket... but oso there r G4... hence i just wrap the grip abit different to get what i want

so, the G5 is the biggest?

grip sizes Victor / Li-Ning -> Yonex
People, don't give any attention to this maths lol, since alle these math stuff are wrong calclated due wrong used units
btw, this may help you:
Grip sizes - comparison: Victor / Li-Ning -> Yonex
G2/S2 -> G5 (small grip)
G3/S3 -> G4 (medium grip size)
G4/S4 -> G3 (large grip size)
I've never seen any S4 (LN) grips before.
There are also some posts about a very small grip G6 (for Japan only)
Most of you will get used to S2 or S3.
