headset stack height and head tube length

Got a technical question on the stack height of a headset as it works with head tube length of a frame. I'm thinking about moving up to a bigger size frame, but I think the steerer tube on my existing fork may be too short. When measuring the total length of the headset plus the head tube, do you simply add the two length values (stack height of the headset and the frame's head tube length) together? Or, do you not include the stack height of the the lower half of the headset when determining total length?

Yes you have to take into account the stack height, also remember that there's the stem and spacers that figure into the equation too. As far as stack height, there are different heights from diferent manufacturers, so if you end up a little short look for a different brand or model of headset. Hope this helps.
