I think this is what you do, it will give you the length to make it and then presto its tuned to your desired hertz!

If i know my port's height,width,and diameter it will set itself at the proper Hz when built? I think i may be confused

No. Figire out the internal volume of the box that is needed for the sub. Then use the calculator on the page I posted and figure out how big your port will need to be. I usually tune my boxes to 35 Hz
