Height and weight for DD age 9

51 replies

PurpleChick2 · 19/01/2026 11:42

Should I be concerned about my daughters height and weight?

she is very tall for her age, in year 4 and easily the tallest in her year, as well as at her after school clubs. She is often mistaken for a child several years older

she has just turned 9, is 147cm and weights 6 stone / 41kg

she eats and drinks normally, no different to my other kids. Has a sweet tooth but we don’t have treats in the house really (otherwise the kids would live of sweets and crisps)

My 12 year old weighs less and is slightly shorter.

im 5’7”. Husband is over 6ft.

Does she sound ok? What do your 9 year olds weigh and how tall are they?

How do you all know how much your children weigh? I don’t really have a clue with DD. She’s on the small side height wise and looks a healthy weight. Why are you all weighing your children?

Mine last got weighed for asthma check up

When I was age 10 in the 80’s, everyone in the class was weighted then their weight written on the board for everyone to add up and divide to get the average weight for the class. I was the tallest in the class- the next person was up to my chin. I was 163cm and 50kg - the same as I am today. I remember a very petite boy weight 25kg- exactly half of me. The comments were awful and I developed bad posture from trying to stoop and fit in. The petite boy never grew past 156cm and was also bullied.

My siblings and I all grew and developed far sooner than anyone else our age, then were all overtaken in secondary school. We’re all now very average.

Wow I remember this too at school age 9, except we all got weighed and we had to bring in what our baby weight was. I was a 9lb baby and that was heavier than most others, and I was tall and weighed more than most of my skinny friends. It really was an important point (in a bad way) in my relationship with my body, I felt like a huge weirdo.

I think that’s why I asked how people find out their child’s weight - I’d never want to suggest she step on the scales or even be aware of it because of this. But I’d like to know if she is healthy on the chart as she’s always been 91-98th centile too.

I know her weight as we were in the doctors surgery the other day, and they have a set of scales - she was weighing herself and her height for fun to pass the time.
I haven’t weighed her for years. That’s what prompted me to think!

Can I ask how you know her weight? My DD is similarly tall, just turned 10 and is 5ft/152cm and solid, also eats big portions that I struggle to reduce without making it ‘a thing’. I’d like to know her weight but as highlighted don’t want that to become a focus.

When I've needed to know my DCs weight, I use the 50p height and weight machine in our leisure centre foyer under the guise of wanting an accurate height for car seats or ahead of a trip to a theme park/waterpark (height restrictions) etc. They know it does weight too, but I don't talk about that result just an "Ooo, 146cm, that's good - you'll be tall enough to go on the death slide next weekend!". Occasionally they ask what the weight said, and I've just given the figure without any other comment.

Reportingfromwherever · 20/01/2026 08:34

To all the people expressing surprise that people know their child’s weight, I don’t think there is anything wrong with a child being weighed occasionally. It’s not that makes kids paranoid about their weight, it’s talk about weight, particularly negative talk. I know my child’s as they are another one in an asthma clinic! 132cm and 28.5kg.

I do understand this. I was a really tall kid, 5ft 5 on my 10th birthday. I remember sitting cross-legged in school assembly an looking along the line an being really paranoid as my legs were thicker than everyone else’s. I felt like an elephant. I was a actually really slim but everyone else was so much smaller my legs were bound to look bigger.

I do think though, that it is important it keep a gentle eye on weight. My DD seeemd to develop a bit of a belly last year. My family kept saying I was being ridiculous as she didn’t look ‘fat’ and is very active. When she was weighed at the GP though, she had put on a lot of weight and jumped up the centiles quite dramatically. I tweaked portion sizes and she has now lost some weight. She isn’t aware of any of this.

It’s ski season so I have to weigh the kids to work out the correct DIN setting for their ski bindings

MapleOakPine · 20/01/2026 19:08

When my DD was 9 she was 150cm and 33.5kg. She's now 18yo and 6 foot!! She likes being tall.

Brokeandold · 20/01/2026 19:40

Our DD changed in Y5/6, body changed, hair texture changed.
I think its all to do with hormones, her periods started around Y6 too, shes now age 15 1/2, not as tall as most of her friends, all healthy tho, great hair!
Our 2nd DS was the same around Y6, he changed alot physically, but at age 15/16 suddenly shot up, became the tallest in our family, now age 23, towers over me, his Dad, older sibling
Read somewhere its the bodies way of adjusting for future growth-it all stretches out!

midnights92 · 20/01/2026 20:18

You can find the centile graphs for height and weight for girls online. It looks like she's right on the top end for both but height and weight are in proportion. Especially if your husband is tall I would imagine she's just had an early growth spurt and will even out later.

I wouldn't comment anything to her. Even if you have concerns about growth continuing, raise it with your GP without her being there, being tall is not a big deal but being self conscious about it really can be.

Olu123 · 20/01/2026 23:41

i could have written this OP!
my 9 year old is over 140cm and weight 40kg. She found my digital scale in the bathroom and steps on it to check her weight. She also wears size 6 shoes and is the tallest in her class.
her brother who is 12 weighs less than her.
she was born at nearly 10lb and has started growing armpit hair (I shave her now) and chest area is also growing.
she is fairly active, I do worry the comments are getting to her, especially her height as it’s so obvious, her classmates seem so little.

GabriellaFaith · 21/01/2026 00:20

I think you need to advise on her physical activity levels?

9 and 40kg? Over 6s. And shoe size 5 what size clothes is she in ?

mini blondes 9 in 2mths is in shoe size 11 and 3st 8 or just under 23kg

i know my dd is a lot shorter than yours at 125/6 but many of her friends are same height as her

angela1952 · 21/01/2026 09:32

My GD is very solid, she's 11 and not particularly tall but very keen on sport and a completely different build to her willowy older sister. She tends to put on a bit of extra weight and then have another growth spurt, I'm expecting that she'll end up reasonably tall but she'll never be a willowy girl which is fine if that is what is natural for her.
Her mother is a similar build and not tall but goes out of her way to take daily exercise to stay slim and healthy. Her father is taller.

YouLookNiceJackie · 21/01/2026 10:33

My DS was 140cm just before he turned 7. He's now 13 and 175cm and mens size 11 shoes. He has definitely slowed down growing in the last 6 months.
He tends to fill out just before a growth spurt and then it all evens out again.

My LO is in year 4 (age 9) and loads are the kids are over 140cm Mine is 132 and very much one of the shortest - only a couple of girls are shorter than her.

is your DD just 9 or closer to 10?

PurpleChick2 · 21/01/2026 11:59

I would say 132 would be average for my DD year. Some notably shorter, but most a starting to grow upwards now. Thankfully! My DD has been a whole head taller than her year for a long time. Also depends on the cohort I guess!

Kielys72 · 21/01/2026 12:02

My DD (now 22) was always taller and heavier (not overweight) than her peers. Fast forward to now and she a healthy weight at 5’8 and loves food. If I had been overly worried when she was younger she’d have definitely picked up on that and today’s outcome may have looked very different. Please don’t compare to other children, genetics play a really big part.

Lots of similarities!
what do you do about comments in your ear shot?
I try to quickly close them down quite loudly so that she hears me, so that if I’m not there she will still remember she is normal and healthy even if she doesn’t know how to respond.

she and her friends don’t seem to notice the height difference. She is friends with the shortest girl in the year so they do look like a funny pair. You’d never guess they were exactly the same age, born just a month apart!
I guess this is what happens when puberty and hormones kick in at different ages.

Did you ever need to speak to her about portion size and healthy food choices?m when she was younger?
my DD would eat all of evening if she could. Typical dinner - Adult portion of pasta with a sauce (mostly homemade), vegetables, fruit and yoghurt. She’d then ask for more, or go back for seconds of pasta an hour later.

Yes of course we spoke about healthy food choices but not portion sizes. She was never looking for more food after meals, so that was never an issue. Have you been to your GP to discuss her appetite? Could it be hormone related? Or has she always looked for more food? For me personally, food was the demon growing up. At 10 I was 5’4 and 5 and a 1/2 stone. But once puberty hit I gained some weight ate more etc… Everyone pointed this out and I developed an eating disorder. Girls and food is tricky to navigate.

Are you my daughter’s mother? Lol
her bestie is one of the smallest (she complains that she is little) and it is quite funny seeing them together.
both mine are September babies so their being the tallest and being commented on didn’t bother me at first.
her brother seemed to slow down (or his peers started to catch up) around age 9 but she doesn’t seem to be slowing down and with puberty 🫣.
I’m quick now to just give a blank stare or not respond enthusiastically when comments are made and move her away.
she likes her food but she is also quite active with sports and insists on doing exercises daily following on you tube.

pollymere · 22/01/2026 02:03

She's around 98% percentile for height and weight. I don't think it matters much as long as it's the same percentile for both. It does suggest she may end up tall — or she could be hitting puberty early.
