A method for sizing a weld tool for forming a resistance spot weld to fasten a joint having at least two sheet metal members is provided. The method includes the steps of providing a plurality of weld force curves, determining a governing metal thickness, determining a total thickness of the sheet metal members, determining a plurality of joint parameters, including a weld gap parameter, a thickness parameter, a strength parameter, an equalization parameter and a sheet stiffness parameter, using the plurality of joint parameters to select one of the plurality of weld force curves, and using the governing metal thickness and the selected weld force curve to calculate a weld force parameter.
