See how tall you'll be. MaxHeight predicts your adult height in about 60 seconds. Answer a few questions — your height, your parents' heights, where you are in puberty — and get your predicted adult height with its likely range. No photos, no guessing: the prediction blends up to four established pediatric methods, built on CDC growth data. Then do something about it. MaxHeight turns your prediction into a daily plan: • YOUR PREDICTION — predicted adult height, your likely range, and how you compare with people your age right now. • A PLAN FOR EVERY DAY — a 365-day exercise plan that follows the WHO and US physical-activity guidelines for teens: impact and strength on build days, mobility and posture in between. Every move is illustrated. • EAT FOR GROWTH — daily calorie, protein, calcium and vitamin D targets from official US references (NASEM, USDA). Photograph a meal or describe it in words; foods the app doesn't know are looked up in the USDA reference database, and anything estimated is marked so you can correct it. • ASK THE COACH — a growth coach that answers your questions and can look at a plate of food, your posture, or an exercise position. • COMMUNITY — ask a question, share progress, and hear from people your age. Text only, every post checked, 13 and up. • TRACK IT — log your height as you grow. Your real measurements sharpen the prediction over time. • STAY ON IT — streaks, achievements, and an optional daily reminder. Where our numbers come from: every figure in MaxHeight traces to published science — CDC growth charts, NASEM dietary references, USDA food data, WHO activity guidelines. The methodology screen shows exactly which, so you can check for yourself. No app can predict height exactly — that's why MaxHeight always shows the range. MaxHeight is a subscription.

Height Predictor for Teens

Put in your age, your height and how tall your mom and dad are, and it works out roughly how tall you'll be when you stop growing. You get a number plus a range, since nobody can know your exact final height. It uses the CDC height-for-age growth charts blended with your parents' heights (the mid-parental thing pediatricians do). I put a screen in that goes through the math step by step and linked every source, so you don't have to take my word for it. Your dot goes on the CDC percentile chart, so you can see what percent of kids your age you're taller than. Measure every few months and log it. If you're mid growth spurt the line shows it. There's a stretch section for posture with drawings and a timer, and a daily check-in for sleep and food. Stretching doesn't make bones longer. Standing straight still adds a surprising amount to how tall you look in photos though. Height maxxing people: this is the bit that tells you what you're starting from. The questions and the chart are free. Seeing your predicted height is a single purchase, I didn't want to do a weekly subscription like the other height apps. No account, what you type stays on your phone and Delete in settings wipes it. Late bloomers exist and plenty of people end up a few cm off any prediction. If your growth actually worries you, see a doctor. Works in cm or ft/in, ages 2 to 20.
