20 Tire

How to measure bicycle shops bicycle sizes /? ie.16 ", 20", etc. Is it the tire to the outside or inside edge or what?

I need to get a new bike for my 6 years old soon. He is on the longest side of a year, nearly 6 years (not fat, just built) and I have no idea on how to measure its current bike to get the size for her birthday next week next. Please help!

Kid's and adult bikes are measured differently, btw. For children, the diameter wheel, which can be printed on the tire sidewall. If not, measure the outside of the tire from one side to the other - Children's bikes are either 12 ", 16", 20 "or 24", so there is enough variation that you will be able to tell fairly easily as one is his. Look at your son's inseam measurement to determine what size to do it. And happy birthday to him!
