The comments on size this will fit are all over the place here. Can w/ the kids one size fits all kids measure the pants. My son 5' 100 lbs?

Yeah it will fit because im about 5'3 and the pants fit good but with the jacket the arm length is small but not that much i would recommend buying it

my son has similar measurements,5,45lb,46 in and it fits him just right, as in any taller he'd start flooding and his arms are a little long. but my son has really long limbs. also he won't be able to layer much which for us doesn't matter as we will be at indoor parties.I was fine since its pretty much one time use, but I'd try to find the inseam measurements.

Google "karate pants size chart." These do run a bit big, so you may want to order a size smaller (or just let your child grow into them)

It may be a little big. I bought it for my 11 year old that is 5 ft 1 or 2 inches. It fits him perfectly.

My son who wears size 8-10 wears a size 0 (zero) dobok. I am 5'1" and wear a size 4 in women's clothing, and I wear a size 3 dobok. The pants fit me just right. Not sure how tall your daughter is... I'd lean towards a size 2, or maybe a size 1. It is hard to say without knowing length of inseam.

I have a very thin 11-year-old and the small was pretty tight on her bare knees. I'm not sure what size your nine-year-old is. I'm guessing if she is very small then she could probably wear these over her pants.

I bought this for my ten year old that is 5ft tall and 95 lbs. this could fit him for at least another year or 2. Hope that helps

My son is 12 years old , 5 foot 4 inches and weighs about 130lbs and these pants were too small. He is a size 14 husky in pants. I hope that helps a little.

My daughter was 9 years old, weigh 70lb, height 55in last year. She is regular build and the Medium fits her with long underwear and fleece sweater underneath. There is still some room for her to grow into it this year. The length of these pants were slightly long last year but with boots on it was ok.

Given that I have only bought one size, and I am a fully grown adult, it's difficult for me to recommend which one you should pick for your son. But, I did scan through the reviews to see which ones mention buying smaller sizes for their children. I came across a few that would at least come close to your son's statistics. The first one I found was bought for a 9 year old who was "Very tall" for her age, and they got her a medium. The reviewer said that if you buy a size perhaps slightly bigger than you were hoping for, the outfit comes with several straps that wrap around the waist and legs that can tighten it. (which I can confirm is true.) The only part that I've ever found to be loose is the upper chest region. I can't even seem to get that region to stay tucked in when I move around too much in the outfit. Also, another reviewer bought this for her 13 year old son who was 5'7 and 120 pounds and chose large. She said it was "a tad loose, but not too long." This is probably the example you were looking for, so listen carefully: Given the fact that you son is the same age as hers, and is both shorter and weighs less than her son, Medium might be a wiser choice - but remember I can't confirm that, I've never bought or tried any other side except for XL. At any rate, I think whether you pick medium or large everything will be fine. The medium might fit perfectly, and the large, if you decided to get that one, would at least be really comfortable, nonrestrictive to motor functions, and more importantly; he'd be able to continue using it as he ages and grows. So either decision you make I think you'll find good things about either of them. Hope I was of help.

Hit or miss situation. These suits are difficult to find in retail stores. Measure your toddlers body with a Taylor's measuring tape and match them with oneils measuring chart. Still, your not guarantee a fit because every child is different when comparing weight and body structure.

You should probably go with his height or the pants would be too short. You can always take them in but you can't add length.

My son is 8 years old & wears a size 7-8, it fit fine. My son is tall, the pants were a little short. No problem, I just made sure he wore black socks.

It will be perfect, no too big. But he will have some growing room. My son is 11 also and in a 10/12. I think the large is the right size to get. My son loves it! And he is picky about how things fit:-)

It should. My son was wearing the 4-6 around that age. It may be a little big. Give him some room to grow

My nephew is 2amd it fits him right on. So It might be a bit small on your son

My husband put my sons on him and it fit. Granted he isn't a large man and has a shaved head, I think if your son is average size it likely will. (accidentally logged in under his account)
