From the moment you find out that you are going to be a parent, you start wondering about your child. What will they be like? What color eyes and hair will they have? Whose nose will they inherit? How tall will they be?
Watching your baby grow and change to a kid, a preteen, and then a teenager is both excruciating and awe-inspiring. Right now, I’m in baby bliss. With my child, I can’t believe how huge her feet are, and I’m curious about how many more times she will outgrow her shoes!
That’s why when I found these baby height predictor calculators online, I was pretty excited. It’s just a silly online tool, but the way the calculation is made is really interesting and is pretty scientifically rooted for an estimate. Then while I was doing a little research on these, I found some information on other things that can affect your baby’s future height.
But first, let me share some links with you. I looked at two websites and used my youngest daughter to compare the process between the two. Baby Center has an easy to use calculator and Infantchart.com has a calculator plus lots of downloadable growth charts.
Both of these charts are pretty easy to use and straightforward. They ask how old the baby is and how tall the baby’s parents are and then calculates an estimate from there. Both of the charts on these pages predict my youngest will be an inch taller than me.
There are some other methods you can use to calculate your own estimate. One is the two times two method. At your child’s second birthday, double their height. My mother in law swears that this is true, although I'm not sure what scientific backing, if any, you could find there. Using growth charts is another method that at least seems to follow logical sense. If you take growth charts and plot where your child’s size lands, you can extrapolate how tall them might grow.
Either way, my curiosity was instantly satisfied with the online calculator, and since I have no concerns about the way my baby is growing, I didn’t feel the need to print growth charts and plot my child. I did feel better knowing that I can access this information if I have a reason to worry later.
More than anything, checking this calculator made me curious about what other factors affect how well your baby can grow. I found these four influences that can make a big difference in the future height of your child:
- Nutrition- Good nutrition can help a child grow to their full potential, but it doesn’t seem to overcome things like genetic markers. Children who are underweight or overweight might be noticeably shorter or taller than other children of their age, but that doesn’t necessarily mean that they will be shorter or taller as an adult.
- Hormones- If a child has a hormonal imbalance or problems with their thyroid, they might grow more slowly or too fast. If they rocket up the growth chart or fall behind, it might be worth asking a doctor about hormonal imbalances.
- Medications- Some medications can affect how fast children grow, especially when taken chronically. If you child has any long term prescriptions, talk to your doctor about any possible risks to their growth potential.
- Health and Genetic Conditions- Chronic illness can inhibit growth in children, particularly if they go untreated. Genetic conditions like Down Syndrome or Marfan Syndrome can change how tall or short your child grows as well.
I guess the only sure way to find out is to wait and watch, but it’s interesting to think about not just how tall my kid would be but what kind of person she will be. Now that’s a calculator I’d like to see!
