What Is the Standard Vital Capacity for Elementary School Students?

Vital capacity varies among individuals depending on physical constitution and is influenced by factors such as sex and body size. What is the standard vital capacity for elementary school students?

What Is the Standard Vital Capacity for Elementary School Students?

Elementary school standard: boys—2,200 mL; girls—2,300 mL.
Average reference values for vital capacity in elementary school students:
Boys: age 7—1,342 mL; age 8—1,496 mL; age 9—1,972 mL; age 10—1,843 mL; age 11—2,010 mL; age 12—2,200 mL.
Girls: age 7—1,213 mL; age 8—1,354 mL; age 9—1,516 mL; age 10—1,685 mL; age 11—1,883 mL; age 12—2,077 mL.
Guidance: A boy’s vital capacity (Y, in mL) can be estimated using the formula Y = 5.29X − 427.1, where X represents height in centimeters.
Daily care: Compare test results against the above reference values to assess whether vital capacity falls within the normal range.

The typical vital capacity for elementary school students is approximately 1,900 mL. Vital capacity refers to the maximum volume of air that can be exhaled after a maximal inhalation, reflecting an individual’s cardiopulmonary function. Individuals with higher vital capacity generally possess greater respiratory endurance. If the measured value falls within the normal range, there is usually no cause for concern. Regular physical exercise daily can significantly improve vital capacity.

For boys in Grades 1–6, the passing thresholds are 700, 800, 900, 1,100, 1,300, and 1,500 mL, respectively; the “Good” thresholds are 1,300, 1,500, 1,700, 1,900, 2,200, and 2,500 mL; and the “Excellent” thresholds are 1,200, 1,800, 2,100, 2,400, 2,700, and 3,000 mL.
