The best way for figuring the gauges you need is this math formula:

(T x 386.4) / (2 x L x F)^2 = UW

T = tension (lbs.)
L = scale length (nut to bridge)
F = frequency (pitch in hertz)
UW = unit weight (expressed in pounds per linear inch. lbs/in.)

For the above formula you need to know the tension you want.
It is best for the neck to have the same tension on all strings (to prevent neck warping). I use 17.5 lbs on all strings... so the formula for the low A' (55 hz.) on my Ibanez MM 28" baritone would look like this:

(17.5 x 386.4) / (2 x 28 x 55)^2 = 0.00071280 -62 gauge. (The answer is simplified.)

To find what the UW is equal to in a string gauge look at the string tesion page on the d'addario website. They will not have the exact UW but you can find something close...

If you want to know the tension of the strings you have on your guitar/bass currently use this formula:

(UW x (2 x L x F)^2) / 386.4 = T

So with the same specs above and a 62 gauge string (which is actually equal to 0.00070697)

(0.00070697 x (2 x 28 x 550^2) / 386.4 = 17.3566258 lbs/in
-Which is only 7/50 of a lb. off...


It's allot of math unless you have a TI-83 or better. But it’s accurate...
