How can you tell when you are done growing? I mean, I've been about 6" by 4.5" for almost 2 years without hardly any growth (1/4" at the most). I don't think and hope I'm not done growing but what do you all think? thanks btw im 16 (just turned a 2 months ago)
It's possible to get a second growth spurt, but if you've been the same for two years I think it's more likely than not that you've finished growing.
nothing wrong with 6" since the average is that plus or minus a quarter inch. As for thickness, well that may develop more as you get older but here again, if you use your equipment well, your size is fine.
