DS2 is 13, he was 13 in April. He's 5’7, the conversation came up tonight and eldest mentioned how he was barely 5 ft at 13. And how at 14 when he went back to school in sept 2020 after lockdown others were shocked he'd grown and he was still only 5’5, he was 5’6 at the end of year 11 and now at 20 he's 5’10 so he did shoot up after he left school

They do have different dads and dp Is 6’3 so we always knew ds2 would be tall too but I didnt expect it to be so soon. He was also prem so tiny when he was born which I know doesn’t make much difference but where has that tiny baby gone!

He seems miles taller than the boys in his year (all boys school) and also at cadets etc, I don’t want him to end up feeling self conscious as I know ds1 was but the opposite how tall are your 13 year olds?

My DD was 5ft 3” at 10. She was taller than me when she was still at juniors .. (I’m 5ft 7”).. I’d say she was 5ft 8 at 12 and now at 15 is 5ft 10”.
my nephew was also really tall, when he was 12/13 he was nearing 6ft! As an adult he’s now 6ft 5”.
We all grow at different rates.. my older brother was always tall, stopped growing shy of 6ft.. my little brother was always quite small, he shot up later and grew till he was 22!… stopped at 6ft 4”

I've got a photo of DS2 on his 13th birthday and he only came up to my shoulder, and I’m only 5’2” tall. A year later, a photo shows he’s grown a bit, but he was still shorter than me.

He finally had a massive growth spurt when he went to college at 16 and carried on growing till he was 21. He’s now 23 and 6’1”, which took us by surprise as I’m quite small and DH is only 5’7”.

Mine is a DD so might not count but she will be 13 in October and she’s the same height as me, 5ft5.
At this age they all grow at different rates though, some are almost fully grown and some still have a lot of growth left in them. It’s impossible to compare.

DS isn't 13 till January and is 5 foot 6 inches currently. I'd say he's on the taller end of average for his year group but by no means is he amongst the very tall kids. Though I have noticed that it's the girls who seem to be tallest in his year group.

Yes, I have a 12 year old and an 11 year old DD and generally the girls are taller than the boys at this age. A lot of the boys still look like babies, whereas
the girls are starting to look like young women.

My son was 5ft 8 at 13, I thought he was going to be over 6ft, but he never grew any more and he's 23 now.

I haven't measured my just turned 13 year old for a long time, but when he stands next to his mates, he is about 3 inches or so taller than the majority so tall, but not massively so. He wears age 14-15 trousers for length and wears a size 7 shoe.

My 15 year old, however, is 6ft 3, still seems to be growing and is in size 11 shoes! He was of a couple of inches or so taller than his friends until about 18 months ago when he suddenly shot up, so I guess that could.happen to him too. He is stocky.though, while 13 years old is lanky and gangly.

Me and their dad are tall though - dad is 6f2 and im 5f11 so I think all the kids.will be tall.

I have 5 kids. when they were 13 they ranged in age between 13 years 0 days old and 13 years 364 days old. 😆
Height wise my boys all had big growth spurts towards the end of being 13. They were all around 5ft 1 when they turned 13, and were around 5ft 8 turning 14. Now at age 23 and 21 (twins) the twins are 5ft 11 and 5ft 10 and my 23 year old is 6ft.
My girls are vastly different in height, one is 5ft tall (age 20) and the other 5ft 8 (age 19) they were similar heights at 11 (around 4ft 11) but dd1 pretty much stopped growing there and dd2 did not. at 13 they were 5ft and 5ft 3
