How can I calculate the cured ply thickness of a laminate?

If you know the weight of the fibres per square metre M (kg/m2), the density of the fibres, Rho (g/cm3) and the fibre volume fraction Vf in the laminate this can be calculated quite simply: M/(Rho * Vf). Using the units specified above this gives the answer in mm.

This method may not work if your laminate is likely to end up with a high porosity or your fibres pack is very coarse and high in crimp.

There’s also a cured ply thickness calculator on this site.
