I just hope my kids aren't any taller than this predicts, even though I know we will have tall kids. I am 5'8" and my DH is 6'5". This calculation puts my DD at 5'10" and my DS at 6'3".

Though if I run this calculation for my DH's parents, he should not be above 6 feet tall. So clearly genetics doesn't follow the rules!

Google khamis roche calculator, its the most accurate

Depends how tall dad is too and other family genes. 5-10 is average for a white guy and not tall. Is he 5-11 or 6-4.

That's what makes it so hard to predict. Both sides are all over the place. My sister and I are both around 5'3" and my parents are on the shorter side but our brothers are both 6'. DH is 6'1" with a brother who's on the shorter side. Their parents are above average in height.

DS is 12 and one of the smaller kids in class at 4'10" and 80lbs. Doesn't help that he has an August birthday. Trying to reassure him that he will have a growth spurt.

Has your DS hit puberty yet, or near to? That will be a tell.

We fit OP's profile. My entire family are super short. DH family mostly super tall.

When DS was 12, he was under 4'10", but he was 97lbs. IMO, your DS is on the very light side, but it could also be because they are not ready to pack on the pounds before the vertical growth. DS was always super skinny till middle school where he packed on the pounds. He got chunky, which he hated. But DH did the same, and told DS that this is normal (for them), and that when they hit puberty, they will stretch out. And yes, this exact thing happened.

DS at 17 is now just shy of 5'10" and super skinny again and was a late bloomer (hit puberty at 15). Pediatrician at last appt said they estimate DS will hit close to 6'. DS growth pattern does not show any slowing down of growth; still on the incline of the growth trajectory. DS was always the shortest in class until he hit 16, then he started growing past the boys who started puberty earlier than him. One of DS friend was the same height as him through ES, then in MS, the friend hit puberty and grew taller than DS, who hadn't hit puberty yet. FFW now that friend who started puberty in MS is several inches shorter than DS and that friend has stopped growing.

IMO, when your DS starts puberty can also be an indication of how tall they might be. Just make sure he's eating enough and getting enough outdoor time, exercise, and sleep* (critical).

This is super helpful. Thank you. DS is not showing any signs of puberty. DH was also a late bloomer. I also heard that it's common to gain weight/pack on pounds before a growth spurt. I guess it's your body's way of preparing!

Its a totally guessing game. No way to know. People hear are so hung up their son's height. So many posts about this. Unbelievable.

Interesting…our oldest is tracking to meet this exactly and be 6’2.

Our youngest is tracking to be 6’7.

So, I guess that formula works…sometimes. Lol

That tracks for my son’s growth so far, he’s predicted to be about 5’9” (dad 6’1”, mom 5’) that’s the same height as my brother (parents are 5’2”, 5’11” so formula is the same)

I’ve never seen this formula before, but it tracks very closely with our adult kids’ heights. 5’7” mom and 5’9” dad have 5’10” son and 5’5.5” daughter. But our 14 year old DS is already 6’.

Animal protein and fat. Kids that eat more high quality foods and fewer processed foods are taller. Sadly, children whose families adopt a vegan lifestyle tend to be smaller and shorter than those that do not.

I am 5’4” (most of my family is tall, I am an outlier) and spouse is 5’9” (his whole family is short) and DS is 5’10” and daughter is 5’4”.

Average is supposed to be the average of your height and your spouse’s height + 5 “.

Mine is shorter than dad.

Depends how tall dad is too and other family genes. 5-10 is average for a white guy and not tall. Is he 5-11 or 6-4.

If one spouse is on the tall side (>5’10”) and the other spouse is on the shorter side (<5’3”) where did your DS end up or is expected to end up height-wise?
