Want to see how tall your kids will be?

Parents often have questions about how tall their kids will be. Will they be short, tall, or average? While there is no magic way to look into the future to see how tall your children will be when they grow up, these height predictors can give you a pretty good idea of what your child's future height will be:

• Kid's Height Predictor - predict your children's future height based on their genetic potential (which is based on their parents' midparental height)
  
  
• Kid's Height Calculator - Two Years Times Two Method, which uses simple linear regressions and doubles a child's height at age two years
  
  
• Yet Another Height Calculator - use your child's current height and where they are on the growth curve right now to predict their future height
  
  

Notes on height predictors:

Keep in mind that many factors may influence your children's future growth, including their overall health and nutritional status and their genetic potential.
