192 pixels high on a sinclair in PAL high would be 3 active lines per pixel, so each character is 24 lines high. Ignoring overscan. That would be about 5mm, or about half a mm per pixel. Clearly depending on the tube will depend on how definite edges are (a trinitron will be better than a shadow mask)

Does that sound about right?
