    Way off. My son is already over 2 feet tall at 11 months old and they are predicting him to be 6’1″ to 6’4″ even though his daddy is only 5’5″. I am 5’9″ and all of the men in my family are over 6’0″. My husband’s relatives range from extremely short 4’8″ to very tall 6’5″! This predicted my son to be 5’10″. My son wears 18 months bottoms for the length right now. He is taller than my twin sister’s 3 year old son.

    I put in my parents heights (mom is 6’1″ and dad is 6’4″) and it was surprisingly accurate. I have a sister three inches shorter than I am (5’10″), this method guessed the height of my parents theoretical daughter to be 5’11″, or one inch taller than my sister and two inches shorter than me.

    I put my parents’ height in the chart to see if it would guess my height…it was way off…my mother is 5’6″ and my father is 5’8″…the generator guess my height to be 5’4″ and I am actually 5’9″. Can’t wait to see what my child will be like. Her daddy is 6’3″…the generator said she would be 5’9″.

    Ok, now I did my daughter prediction…I am 5’7 & my husband was 6″2…predicted 5’7 for my daughter. She turned out to be 5’8…Pretty close! I agree with another reviewer…” not real accurate but fun to do ” :) Thanks :)

    What’s the average height for a baby at four months? My son is already 26 inches is that considered short or tall for his age?

    My mom was 4’11″ and my dad was 6’1″ im 5’9″ but my sister is only 4’9″. No dwarfism, just small people. She and I look exactly alike despite a 17 year age difference all the way down to the direction the curls in our hair grow. There’s no predicting height. Some people are going to have the grass tickling their butts when they run like my sister and im destine to smack my head on chandeliers.

    My dad is 6’1″ & mom 5’11″ & I came out to be 6ft tall. (It said I should be 5’8″). But this is fun. I’d be interested in trying it in other people.

    This is Just for Fun ladies and genlemen. The more accurate measurements are that like Ann mentioned about their height at 2 years. Its in medical and psychology textbooks so there must be some truth behind it. However, science isn’t always accurate either.

    My son is 2 and already 3 ft 4 in. I am 5’2″ and his father was 6’1″ and it says he will be 6′ even. Sounds right to me…

    You people think this can really tell you 100% how tall your baby will be ? You’ll just have to wait and see.

    This is just an average prediction. It obviously depends on genetics. Again it’s an ‘average’ ‘prediction’.

  16. Avatar of Andreana Andreana says:

    This is not accurate. Said my daughter will be 5’3…she is 5’3 and only 11. Doctor said she will be around 5’7.

  17. Avatar of Izzy Izzy says:

    My daughter is already 11 and is very tall and I was wondering how tall she would be after she stops growing and with a 6’3 dad and a 5’4 mom it says she’ll be 5’6 she is already 5’7 though and won’t stop growing anytime soon (:

    best predictor is at their 2 year appt to multiply their height at 2yrs old and that will be more accurate to a full height. My daughter at 2 was 33″ her height will be 66″ (5’6″) She is 5 now, but she is shorter than other kids and will more than likely take her height from her father’s side of the family which the women are not very tall. Another thing is to notice how big their feet are growing. The feet are the platform for the height, you never see a short person with big feet! My daughter still wears a size 10 her cousin that is 7 months older is in a 12. I have other cousins that are not 2 yet and wear a size 9!! she will be tall like her daddy!!! Nothing is going to work…but the multiplation of their height at 2yr and the size of their feet will generally being a telling sign of their height!

      I am 5’1″ and wear a size 11 shoe. So yes, short people do have big feet too.

    • Avatar of Christina Christina says:

      My son is 3 mo shy of 2 yrs so I’ll have to check his height at that time..good point to know. I wouldn’t ‘t necessarily go by foot size though. I’m only 5’1″ but have a shoe size of 9!!

    Don’t forget the importance of diet and nutrition – those things affect height. Another thing to think about would be if your parents started smoking in their tweens and early teens – if they did, they would have been taller if they had never smoked!

  20. It says I’m supposed to be 5’8″ and my brother 6’2″. In reality, I’m 6’2″ and he’s 6’6″… was waaaayyy off in our cases. Lol. Still fun tho! :)

  21. Avatar of Erika Erika says:

    My mum is 4’10 and my real dad is 5’5 and it said I would be 4’10. I’m actually 5’1. My younger sisters (I’m the oldest) are taller than me. Well except for the second oldest oldest she’s 4’11 my other 2 sisters are 5’3 and 5’6. So this tool isn’t very accurate.

    My mom is 5’6″ and my dad was 5″10 predicted me at 5’5″ im 5’8′ predicted my daughter to be 5’6″ im 5’8″ is 5’10″

  23. Avatar of tovahjs tovahjs says:

    This is not very accurate. My mom is 5’7″ and my bio dad is 5’9″ this predictor said I would be 5’5″, I am 5’8″. My baby brother whose father is 6’5″ is 6’8″ it said he would be only 6’3″. My son who is just fifteen is about 5’9″ his dad is 5’6″ and it claims he only has 1 inch to go. My other son, we will see about. My older daughter I know will be petite but I hope she will be taller than 5’4″. Not so she will make it taller than that though with all her food allergies. My newest daughter is only 15 wks today, she is the shortest of all 4 at this age but the chunkiest, so we will see how tall she turns out. :)

  24. Avatar of layla layla says:

    This is pretty accurate for me. My mom is 5’9, dad’s 6’7. Said I should be 5’11 and I am actually 5’11 and maybe a few extra cm. So my brother will be 6’5, he’s around 6 ft now as a freshman. Great calculator! Drs say he’ll be 6’7 so let’s see where he will be after this summer lol c’mon grow so you can be a even better hooper!Lol
