How to calculate width and height of check box?

How to calculate width and height of check mark of CButton created with BS_CHECKBOX?

I need to resize this button if text not get in client area of button.
If I use simple button I calculate width and height of text by using DrawText with nFormat value DT_CALCRECT, but with button with BS_CHECKBOX flag DrawText not calculating text's width correctly...

Can I calculate width and height of this check mark? Or this value stored in Registry?

If I can't I need to use my own check mark in owner draw button... :-(

If the check box does not have text (the caption of the button), use the following code.

CRect rect;
TheButton.GetWindowRect(&rect);

int nWidth = rect.Width(), nHeight = rect.Height();

if (hBmp != NULL)
{
   BITMAP bmp;
   GetObject(hBmp, sizeof(BITMAP), &bmp);
   printf("%d wide, %d high\n", bmp.bmWidth, bmp.bmHeight);
}
