Ah right you are. For that I think you can use something like this:

TEXTMETRIC tm;
GetTextMetrics(hdc, &tm);   // Dimensions of the system font don't change
                                         // during a Windows session
int cxChar = tm.tmAveCharWidth;
int cyChar = tm.tmHeight + tm.tmExternalLeading;

There's a bunch of these calls in the SysMetrics examples you can look at here:
