Frequently asked
How accurate is the height prediction?
We combine the mid-parental height formula with Khamis-Roche style adjustments. Studies show these methods are typically within ±5 cm of actual adult height for most teens. Predictions improve with more data points and consistent habit tracking.
Can I really still grow taller?
It depends on your age and growth plate status. Most growth happens before 18 for boys and 16 for girls. Tallevate estimates remaining potential based on your stage and shows which habits — sleep, nutrition, posture — affect the outcome most.
Is this medical advice?
No. Tallevate is an educational tool. We do not diagnose growth disorders. If you have concerns about your child's growth pattern, please speak to a pediatrician.
