My son is almost 11 and wears a 12-14 shirt. I had to order 14-16 which fit him surprisingly well. The arms were a bit long, but as long as your son isn't skinny, you should be fine. My boy is by no means overweight, he is exactly where he should be at this age, above average, he is no shrimp. The shirt will look stylish for a photo shoot.
