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?

My tiny 9 year old is 121cm tall, and weights 25kg.

Rubinia · 19/01/2026 17:04

my son is just over 142cm and weighs around 33kg. He’s very sporty so lm not too worried about his weight.
is she quite active?

DS is almost 9. 135cm and 32kg.

Bitzee · 19/01/2026 17:54

Almost 9YO DD is 135cm and 30kg
To add in case it’s of interest/relevance I’m also 5ft7 and DH is 6ft2

Watchoutfortheslowaraf · 19/01/2026 17:54

Mine is 10, 142cm and 5 stone 3. Mine is actually quite tall in her year (year 5) so yours does sound very tall. But that’s fine, we’re all different. Does she do netball? It’s a great advantage to be tall in netball.

OneHundredDays · 19/01/2026 17:55

Well she's tall but she does sound heavy for her height. My athletic DS (12) is 168cm and 42kg.

My DD is the opposite end of the spectrum to yours. At 10 she's 132cm and just 22kg. She's technically underweight but she's sporty, strong, never sick and full of energy so I'm not worried.

I'd try to discreetly make subtle diet changes and encourage more movement. The longer you leave it the harder it gets.

HarvestMouseandGoldenCups · 19/01/2026 18:07

She in the healthy centile for her height.

CleanSkin · 19/01/2026 18:47

She is tall, that’s the way it goes developmentally - but trust me, please do not say a thing to her about her being too tall or too heavy.
It completely f#cks your self confidence up, in my case for life.

PurpleChick2 · 19/01/2026 21:07

She does a lot of sport - karate, swimming, football and athletics clubs. She didn’t like netball after a term.

she is tall, not chubby, but she is heavy and solid.
she eats big portions. I didn’t realise how big until we had friends round and their kids ate half the amount of food that she ate.

my the kids eat the same amount but aren’t as heavy as her.
i guess a lot is genetics… i was heavy as a child and have had a BMI of about 27 my whole life. So not obese, but a little bit overweight.

This really bothers me and I see it a lot!!

when adults see her for the first time in a while, they say to her ‘wow aren’t you big’, ‘gosh you’re so tall’, ‘ you’re massive compared to my Lucy*’ etc.

I hate it! I always close those comments down quickly and will take a point of saying it in front of her ‘she is tall for her age but we all grow at different speeds. She is perfect and healthy’. Etc.

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.

OperationalSupport · 19/01/2026 21:24

DD is 8 and a half, about 139cm and about 31kg. She is tall for her age, but she was above the 91st centile as a baby, I’m 5ft7 and DH is over 6 feet so she was never going to be petite.

Blondeshavemorefun · 19/01/2026 21:27

Suprised mini blondes isn’t taller

I’m 5/7 dad is 6/2 - she’s def a short arse compared to some on here and some school friends tower over her

Blondeshavemorefun · 19/01/2026 21:27

She’s under 23kg

Wintertime2025 · 19/01/2026 21:28

My daughter is exactly the same height and weight do in top 99% got both. My DD is already going through puberty (no period yet). But she looks so different to her friends who are small, completely flat chested etc. luckily she hasn’t noticed but we have talked a lot about body development.

Wintertime2025 · 19/01/2026 21:29

Ps I know her weight as she has asthma and gets weight etc

BertieBotts · 19/01/2026 21:29

Going by the centile charts, she's over 98th centile for height but just under it for weight, which makes me think she's in proportion and just tall.

In fact if you look at the BMI lookup on here which compares height and weight centiles, she's roughly on 75th centile for BMI. They don't consider it overweight unless the BMI centile is 91st or higher.

Obviously these are rough tools but it doesn't look like anything to be concerned about having read through all the guidance here.

Boys and girls have different builds. According to the centile charts, OP's DD is in proportion for her height and sex. (As is your DS).

slapmyarseandcallmemary · 19/01/2026 21:34

My 8 year old (9 in few months) is 152 cm and 6 stone. Size 5.5 in shoes.

Playeden · 19/01/2026 21:37

mine was 152 at 9.5 and now 163 at 10.5.
but… has now started periods.

yours is about 98th centile. But could just be earlier development.

Mine is tallest kid in year. But my other kid had truly tall kids in her year and those girls will be 6ft and they were like giants to my eldest. My eldest was only 138 at 9.5 and stopped growing at 169.

Hallywally · 19/01/2026 21:44

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?

Studyunder · 19/01/2026 22:11

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.

BertieBotts · 19/01/2026 22:13

Well we don't have a set of scales any more as DH left it on top of the washing machine after mopping the floor, and it wobbled off and smashed. But we have generally had a set of scales in the bathroom, I had them there growing up so it seemed like a normal thing to have. It is helpful to keep track of younger children's weight for things like car seats and medicine dosing (I am abroad where children's medicine is dosed by weight not age) and plus it is just generally interesting to them because they like seeing their weight get bigger as they grow. I would weigh myself as well every now and again just out of interest and sometimes to check in terms of health.

If you have difficulty with the emotional side of weighing yourself regularly then I can understand not wanting to have scales in the house, but if that is not an issue (and it is not for anyone in our family) then it is a fairly normal item to have at home.
