Broadly the profile's frame width or depth in millimetres — wider series suit larger windows and sliders, narrower ones suit standard windows.
It depends on the window's size and type. Large sliders need wider, stronger series; small casements need less. It's chosen per opening.
Not universally — it's about matching the series to the opening. Over-speccing adds bulk without benefit on a small window.
