The average maximum capacity is around 6 liters of air, but when you exhale approximately 1.2 liters stays in your lungs. An easy way to measure this is to take a balloon and take a deep breath, then inflate the balloon as much as you can with just that breath. Measure the resulting diameter of the balloon in centimeters, then use the formula:
Volume = (4 / 3)(3.1416)(diameter / 2)^3
Then divide by 1000 to get your lung capacity in liters.
Total lung volume equals Vital Capacity + Residual Volume.
Your total lung capacity is the total volume of the lung after maximum inspiration. (average 6 litres).
The term for the total amount of exchangeable air in the lungs is called the total lung capacity. It includes the sum of all lung volumes, including tidal volume, inspiratory reserve volume, expiratory reserve volume, and residual volume. Total lung capacity provides insight into how much air the lungs can hold.
vital capacity
The lung volume that represents the total volume of exchangeable air is the vital capacity. It is the maximum amount of air a person can exhale after taking the deepest possible inhalation.
No. A spirometer can be used to measure the volume of breath a person can expire but it is impossible to expire your entire lung capacity. This is due to the "dead space" capacity that remains to stop the collapse of the alveoli. As the alveoli are spherical and lined with mucus if they collapse it would be impossble for them to be filled again and so some air must remain within them. It is, however, possible to estimate someone's total lung capacity from the spirometer reading.

Total lung CapacityTotal Lung Capacity. Also known as TLC, this is the volume of the lungs after a maximal voluntary inspiration.
The equation to measure lung volume is Total Lung Capacity (TLC) = Vital Capacity (VC) + Residual Volume (RV). TLC represents the maximum amount of air the lungs can hold, VC is the maximum amount of air that can be exhaled after a deep inhalation, and RV is the amount of air that remains in the lungs after maximum exhalation.
Residual volume
The upper right lobe of the lung occupies about 28-32% of the total lung volume in most individuals. It is one of the five lobes of the human lung and is responsible for a portion of the lung's function in respiration.
Total lung capacity can be determined through a pulmonary function test, which measures the maximum amount of air the lungs can hold. This test involves breathing into a device called a spirometer to assess lung volume and capacity.
