wievport edge, line and vertex dimension (no zoom or dpi increase, already tried)

Hello to all, is there a way to increase in arbitrary way the thickness of the line in the viewport ? (and also the dimension of the vertex glyph ?) I don’t want to double everything but the edge should be bigger in proportion with everything else (as far as I know still no solution)
THanks in advance for every suggestion

I don’t know how to widen edges, but if by “vertex glyph”, you mean the dot at vertices in edit mode, those can be adjusted under the themes section of user preferences, in the 3D view group
