I am 17 years old boy and want to make abs does it will affect my height .plz help me on this?

Abs and height: Exercises to create strong abs will not have any impact on your height. You are likely already near your adult height.

Be aware: Part of getting prominent abdominal muscles is accomplished through diet as well as exercise. To get such abs you need to drop your total body fat content below 10% and usually between 5-6%, The average kid your age carries about 20% of their weight as fat. So consider what it takes to drop your weight 10% and still work out and maintain nutrition enough to grow muscles.
