Default Master and Slave Cylinder Question

How close do the master and slave cylinder's bore and stroke area need to be to operate properly? If the master doesn't move enough fluid then the clutch won't disengage, but, I read that if the master cylinder moves too much fluid it will damage the throwout bearing. I know that .4415 inch is perfect (see below) but I need to know what I have to work with.

Camaro/Firebird T-56
Bore X Stroke = Area
3/4 X 1 = .4415

according to your calculations, shouldn't you be getting:
3/4 X 1 = 3/4 ?? (0.75)

try

(( bore/2 ) ^2 x Pi ) x stroke.

Pi x radius^2 x height
Pi = 3.142
radius = bore divided by 2
height = stroke

0.75/2 = 0.375
0.375 x 0.375 = 0.141 ( rounded up )

3.142 x 0.141 = 0.443
0.443 x 1" = 0.443
