Enter your height (in) into the Ideal Race Weight Calculator. The calculator will evaluate the Ideal Race Weight. 

Ideal Race Weight Formula

The following two example problems outline the steps and information needed to calculate the Ideal Race Weight.

IRW = 19*H^2 / 703


  • IRW is the Ideal Race Weight (lbs)
  • H is the height (in) 

To calculate your ideal race weight, multiply 19 by your height squared, then divide by 703.

How to Calculate Ideal Race Weight?

The following steps outline how to calculate the Ideal Race Weight.

  1. First, determine the height (in). 
  2. Next, gather the formula from above = IRW = 19*H^2 / 703.
  3. Finally, calculate the Ideal Race Weight.
  4. After inserting the variables and calculating the result, check your answer with the calculator above.
