hiya low profile are wider but project less so dont stick out as much, and high profile project more but are not as wide as the low profiles i dnt really know about medium profiles but im presuming they are somewhere in between lol!
for example a 380cc low profile is 13.3 cm wide and sticks out 4.4 cm. but the high profile 380cc is 11.7cm wide and sticks out 5.3cm. sorry if thats confusing x
