While taking good care of your body may help you grow taller, your height is mostly determined by your genetics. Once your growth plates are fused together, you will stop growing taller, which usually happens between the ages of 14 and 20.If you're still growing, good nutrition and a healthy lifestyle may help you get taller. Additionally, you might be able to increase your height by about 0.5 to 2 inches (1.3 to 5.1 cm) by stretching out your spine daily.
