I think width is an important size too and I always take track of it by measuring with a caliper. My last measurement is 4,7 cm @ midshaft and 3,8 cm just under the glans where it narrows a lot.. the rest of my shaft is between 4,5 and 4,6 cm wide... my mseg is 14,1 cm so my girth/width ratio is exactly 3 this means I haven't a flat penis nor a cylindrical one, just balanced.. what's your erect width measured with a caliper too??
