To determine proper drug dosages for children, calculations are most precisely made on the basis of the child's:
1. Weight
2. Height
3. Age
4. Body surface area

Drug calculations are not most precise when made on the basis of a child's height. Drug calculations are not most precise when made on the basis of a child's age. Children vary widely in size and maturity for chronological age.
