Minimum Weight Class Calculator

Enter your current weight and body fat to find the lowest weight class you can certify at using current body fat floor (7% for boys, 19% for girls)

Enter a weight and body fat percentage above to see results.

Method: lean body mass is held constant and projected to the body fat floor (MWW = lean mass ÷ (1 − floor)). Classes shown are the 14 NFHS high school classes. The descent plan limits weight loss to 1.5% of body weight per week from the assessment date. The 2 lb growth allowance raises each class limit on a date set by your state; check your state's rule on how it applies to minimum class eligibility. Body fat should be measured while fully hydrated. Official certification weights come from your state's assessment program — use this as a planning tool.
