Yes, that is to be expected.

Don't know why that is.
Have a look at  GetTextMetrics() and the  tmMaxCharWidth  that it
returns.
You might be able to use that value to calculate relatively stable
sized gadgets.
Then, you could use  GetTextExtentPoint32()  to calculate the size of
you actual string.

TEXTMETRIC metric;
SIZE size;
GetTextMetrics( hdc, &metric );
GetTextExtentPoint32( hdc, TheString, strlen(TheString, &size );
GadgetChars = 1+ (size.X / metric.tmMaxCharWidth).
