Road and Street dimensions
Road width
4-6 m per lane is fairly reasonable.
Cobblestones
A cobble is defined on the Udden-Wentworth scale as a stone with a particle size of 64-256 mm and a genuine cobblestone road surface will be made of natural stones of varying size but approcimately within that range - perhaps mainly in the medium-to-small range.
What we usually call cobblestones today are strictly speaking "setts" or "Belgian blocks", cut stones of equal size. Typical dimension for a sett is about 10 cm. taking into account the space between them, expcet 8-9 stones per meter.
