Know what to expect.
Enter a few numbers and see where your height is heading. Centile does the maths with a published growth method, so there are no charts to read.
For ages 13 to 19

Everyone around you is growing at a different speed, and you’re left wondering where you’ll end up. Centile works out your likely range in a minute, then shows you growing, one height check at a time.

Checking for your child? Centile for parents
Get your free range.
From your mum’s and dad’s heights. It’s a rough guide, and nothing is sent anywhere.
Middle
For a narrower range, Plus uses the Khamis–Roche method. It takes what you’ve already given and adds your age, your height today and your weight today.
Why Centile
Better than guessing.
A minute a month.
Measure, type it in, done. The change since last time and your chart appear on their own.
Every centimetre on record.
Every height check is dated and kept, so you can look back whenever you like. It all stays on your phone.
See how you compare.
See how your height today compares with others your age, with Plus.
What you get
Inside Centile Plus.
Narrow your range. Watch yourself grow.
See where you stand.
Your height today against the top and bottom of your range. Plus narrows it with your age, your height today and your weight today. For ages 13 to 17½.
See how far you’ve come.
See each height check, the change since last time and the chart. Plus reminds you once a month.
Make sure nothing holds your growth back.
Food, sleep and exercise help you grow normally. Poor nutrition and real sleep problems can hold growth back while you’re still growing. No habit adds height beyond what your genes allow. The daily check-ins help make the basics a habit.
Daily check-ins for food, sleep and exercise.
Log how you ate and how long you slept, start a routine, and see your last seven days as charts.
A week of meal ideas.
Breakfast, lunch, dinner and snack ideas for every day, with easy swaps. No calorie counting.
Guided exercise routines.
Three routines, each with a warm-up, bodyweight work and a stretch, shown step by step.
Privacy
Private from the start.
No account and no ad tracking. Centile asks only for a first name or nickname and keeps it on your phone with everything else. An iPhone backup may copy it; on Android nothing is backed up.
Free and Centile Plus
Start free. Upgrade when you want more.
Free uses the Tanner method, a proven height formula. It needs three things: your mum’s height, your dad’s height, and whether you’re a boy or a girl.
For a narrower range, Plus uses the Khamis–Roche method. It takes what you’ve already given and adds your age, your height today and your weight today.
Your range
- your range, from three things: mum’s height, dad’s height, boy or girl; and

What it can’t do
Centile can’t promise how tall you’ll be.
Nobody can. Centile doesn’t know about puberty, illness, medicine or food. It can’t spot a growth problem either. See how we work out your range.
Common questions
Straight answers before you start.
Will Centile tell me exactly how tall I’ll be?
No. You get a range, and it’s a rough guide. Plenty of people finish outside their range. See how we work out your range.
What if I’m worried about my growth?
Talk to a doctor. Centile is a guide, not medical advice.
What does it ask for?
Free asks three things: your mum’s height, your dad’s height, and boy or girl. It also asks you to tick that you’re 13 to 19. Plus adds your age, your height today and your weight today, for its narrower range. Everything stays on your phone.
Do you see my heights?
No. Everything you enter stays on your phone, and there’s no account. Apple or Google runs purchases.
What ages is it for?
13 and over. The Plus range runs from 13 to 17½. Centile is made for teenagers, so it starts at 13. It stops at 17½ because the published method behind Plus (Khamis–Roche, 1994) has figures only up to that age. After 17½ the free range still applies.
When can I download it?
Now. Centile is on the App Store for iPhone and on Google Play for Android. The free calculator works on any phone.
