I'm 5'9 1/2 and about 164lbs and a Medium fits well on me. Maybe this will provide you with some guidance.

I'm 6'1" 175lbs and a medium works for me. I believe it should work for your son.

my son is 46 inches tall, we bought small it was right fit or bit shortI think medium would be good, thinking large would be too big

Yes, if he is a big 12 year old. My son will be 12 in 2 months and is 105 lbs and a small fit him well.

I bought this for my son for his 4th birthday in August. He's a bit on the small side, too, but it's a great size for him. Hope that helps!

S size is good. I'm a male 5'5" 132lbs. I purchased XS size, but that's a little bit small.

I bought this vest in a size small as a Christmas present for my 5 year old son who weighs about 40 lbs. If you want him to get a lot if wear out if it, I would suggest going up one size.

My son is 5' and thin. The size small is slightly large for him, but I wouldn't 't have ordered any other size.

My son turns 10 in a few days and is about 5 feet too and 82 pounds. X-large was perfect for h. My daughter who is 8 got the large and they are shorter, so would be too short for a boy of 5 feet.

I bought for a 5 year old boy, normal size. He weighs 46 pounds. It fits nicely and he should be able to wear for at least another year.

I think it might be a little small. My son (who just turned 6 and is wearing size 5/6) fits perfectly in this now. In a year it will probably be too small.

My son is pretty small & was 5 yrs old when I bought. If he's a bigger child I'm sure it wld

Consider it a small size. My son is also 5 yrs old it's good on him but he has a small head. I hope it helped :)

I bought it for my 12yr old son who is 5'4" approx. 150lbs. It fits him good, maybe a hair big but works well.

my son, who is 19, is about the same build as you. He ordered the small and is happy with that size. The legs are short, but that works well when he is out hunting and wears wool socks & his Danner 12" boots. The size medium would be too bunchy in the seat/groin area.

A small would fit a 9 or ten year old at best. I'm a large and ima pretty big kid 5'10 ,230lbs so id say if the child is less then 190 I'd get him the small
