My son will be 5 on Jan 1st :) and he is big for his age about 3ft in height and 50 to 55 Lbs. I was thinking a 16 inch would be a good size just not sure. I know it sounds weird that I'm asking but Mom is being very difficult and we are currently in the middle of a custody hearing that after all is said and done he will be with me 50% of the time :) so I don't have him yet to get an accurate size. Ugh I wish I could find that perfect world where things like this don't happen. Anyways if there are any parents out there that have a similar size boy can tell me the appropriate size to get I would greatly appreciate it thanx.
 
the 16 inch might fit....but you still may have to take the seat down as low as it will go. If nothing else helps the 12" is probably too short. I think you are on track and if he doesn't quite fit the 16 right now then he likely will in a few more months, give it time he'll grow into it!
 
How to calculate frame size:
1. Measure inner-leg length
2. Multiply it by 0.65

Example (you have an inner-leg length of 83cm)
83cm x 0.65
=53.95
=rounded off to 54 cm frame size.(multiply your answer by 0.3937 to get the size in inches)
