Can someone tell me how to calculate master cylinder bore

[Samckitt]

I am running C5 Vette front calipers with 95 F body rear calipers (basically same as C4 Vette). Not sure what the bore diameters or volumes of them are, but was hoping someone would know & could tell me how to figure master cylinder bore diameter. On it now I have a police/taxi B body master cylinder. I think the bore is 1" but not 100% sure.

Thanks,
Scot
