Did anyone play with different grip sizes (I mean play not try)? Which did you choose on the end and how big is your hand (see the first page)?

I've played with G5 with one overgrip, G5 with 2 overgrips, and G4 with one overgrip. The G5 with 2 grips, and the G4 with one are the best for me; I wear out the G5+1 grip quickly, and get blisters. I haven't measured my hand, but on a piano, my fingers stretch 10 keys, so....

I need your data to calculate the average grip size (according to the hand size of course). Please measure your hand size (see the picture in the first post) and the circumference of your racquet handle where you holds it.

The grip size according to one post for now (thank to Jerby) would be:
Gs (grip circumference in cm) = h (in cm) × 0.74
where h is the size of your hand, measured as shown on the page 1 of this thread.
example: you measure your hand h = 12.2 cm ---> Gs = 9 cm ----> =~ G3 grip size!
Please report your grip sizes and the sizes of your hands to adjust the formula.

G3 with original grip on and no overgrip or
G4 with 1 to 2 overgrips or
G5 with 2 to 3 overgrips (probably to much overgrips)
So in this case I would choose G4.
I, personally, get from formula 8.5, so mine handle would be optimal with G4 or G5 with additional overgrips.
BUT: this formula is based on Jerbys data of HIS hand and therefore would be very useful to rich this data pool with YOUR measurements and your handle sizes, so the formula would be more statistically significant and widely useful!

Is the formula a subtraction? It seems that way, but the way it's been presented looks confusing.
Also, I still do not quite believe that it does properly factor overgrip unless some more clarificaiton is needed. I bascially end up with a G2 if the palmn is measure at the bend line if the palmn wasn't bend, and G3 if it is. The other issue is, the G5, saids 2 to 3 overgrips, however I'm using G5 with 1 overgrip which suits me just fine
I believe some more clarification on the form of measure is needed.

y = kx + n
since there is only one (Jerby) who gave his data. Therefore, n becomes 0, so:
y = kx
k=0.74 (you can recalculate his data from page 1 by yourself), therefore
Gs (grip size) = h (hand) × 0.74
I chose Jerby's data also because his choice of the grip size according to his hand size seems reasonable.
If someone would give his data, the formula would change to:
Gs = h × k + n
and it would be more reliable than in this one-data form. In current form you acctually get, which feeling Jerby like at his racquet (excluding softness and surface characteristics - just circumference)
I know, that some prefer big and some thin handles, but the choice of the grip size (handle size) depends on the gripping technique. If you want to use your finger power properly (see the picture) you should choose somewhere around h×0.75, but if you hold your racquet very firmly and full in the palm (like I did till now - no use of fingers but stronger use of forearm), you will choose bigger grip size like h×0.83 or more.
If you have some more questions, please, don't hesitate... I realy want to get this formula, but I need your data (hand size, circumference of your ready-to-go racquet and maybe you should tell, how do you hold your racquet - if you use your fingers like in the picture bellow or you hold it full in your palm)

Ok thanks for the clarification. I will have the data later on in the afternoon since I have to go out very soon.

11.5cm = hand measurement
grip circumference = 72mm aka 7.2cm (racquet 1)
g4 sized grip, stripped to the wood then 1 layer of tournagrip
grip circumference =11.2cm (racquet 2)
g3 sized grip, stripped to the wood then 1 layer of supergrap

What would be the purpose of this data? I don't see it pointing out much else other than:
small hands - small grip
big hands - big grip
medium hands - medium grip
Coming up with these sorts of ergonomic relationships are really more for legislative purposes rather than actually optimizing the user-tool interface.

Using Yonex G5 with 1 yonex strong grip.
Note: but I don't even know if G5 is suitable or not. Seems not much difference between G5 and G4.
