I'm no expert on this but I'm in a physiology class now and just finished a lab on pulmonary volumes and capacities. We used the following formulas to calculate predicted vital capacity:
Males: VC = (0.052 x Height in cm) - (0.022 x Age in years) - 3.6
Females: VC = (0.041 x Height in cm) - (0.018 x Age in years) - 2.69
My lab manual references a study by Kory, Hamilton, Callahan:1960 for this formula. I was in the process of trying to find that study when I can across your question. Hope this helps.
Vital capacity varies depending on the size of the thoracic cavity, which tends to correlate with height. Lung capacity varies with height, weight, age, gender, and ethnicity.
Four factors that can affect the vital capacity of a person are age (vital capacity decreases with age), gender (males tend to have higher vital capacity than females), height (taller individuals usually have higher vital capacity), and physical fitness level (regular exercise can increase vital capacity).

Predicted and experimental values for vital capacity can differ due to various factors, including individual variations in lung anatomy, health conditions, and environmental influences. The predicted values are typically based on population averages and do not account for unique personal factors such as age, sex, height, weight, and fitness level. Additionally, measurement errors during the experimental assessment, such as improper technique or equipment calibration, can further contribute to discrepancies between the two values.
the vital capacity of lungs is 3.5 liters to 4.5 litres
vital lung capacity is how much air remains in your lungs after you exhale
My vital capacity is 1650cc (Yes, it's very low, but I'm twelve and I'm small). cc is used to measure vital capacity.
bigger body surface area = bigger vital capacity
Vital Capacity (VC)
A teenage girl will likely have the same vital capacity as an adult woman. About 5 to 6 liters of air would be the vital capacity for a 15 year old female.
Vital capacity is the amount of air you can breathe out after a maximum inhale. When it comes to determining vital capacity it’s basically calculated by the inspiratory reserve volume in addition to the expiratory reserve volume.
