Question:
Hello,
I’m 14 and 2 months, my Tanner stage according to the test on the website is 3.2, I’m 5 feet 5 inches (46 kg), and my wingspan is 5 feet 7 inches. My dad is 6 feet so is my older brother and my mom is 5 feet 4. I have multiple questions:
- Do you still grow after your voice cracks? I grew 3.5 inches before my voice cracked. I reached 5 feet 5 inches. I have read multiple sources saying you get a voice crack after your main growth spurt. I tried a height velocity calculator (I know it’s not accurate) and that says that I’ll have my main growth spurt when I’m 14 and 6 months meaning February.
- Is my growth pattern supposed to be the same as my brothers? I was 5’1″ when I was 13 and currently I’m 5’5″ (at 14) and he was 5’6″ when he was 13, and when he was 14 he hit his spurt and became 5’9″, He is currently 16 years old and 6 feet 0.5 inches. Do different growth patterns have an effect on your final height?
- Does having a larger wingspan mean that I will grow more?
- How accurate are height velocity calculators?
Thank you for clearing my doubts and worries.
Answer:
For most boys, your voice begins to crack after you reach your peak growth rate. It is not an absolute rule. Many systems mature in a particular order, but events between systems are only loosely connected. The calculator asks about several of those systems and tries to create a weighted average across them. One system can be ahead of or behind another. But what you need to understand is that even after you reach your peak growth rate, you still have about 2.5 inches of growth before your height growth completely stops. You just don’t grow as fast.
Since you’ve grown 3.5 inches in under a year, you are definitely in stage 3. You’ll be in this stage for about two years. That doesn’t mean you’ll grow rapidly and constantly during this stage. Growth will pause as your body works on other systems to match your new size. You don’t have enough energy to sustain growth in everything at the same time. Even after you reach stage 4, you’ll grow another 1 to 3 inches as your body slows down.
Since you started shorter than your brother, your final height will most likely be less than his. Based on your parents’ heights, the minimum height for boys in your family is 5’8″.
The height velocity calculator I know uses several measurements to estimate when you will reach your peak growth rate. It says the accuracy is only as good as the measurements, and it’s most accurate when used within 2 years of your peak growth rate. This information is then used by an adult height prediction that is accurate to within 2 inches 95% of the time.
