🫁Lung Capacity Age Predictor

Predict lung capacity and lung age by height, age and smoking

Lung Capacity Age Predictor Guide

Forced Vital Capacity (FVC) is the total volume of air you can forcefully exhale after a maximum inhalation. It peaks in your mid-20s to early 30s and gradually declines with age. Using the ECSC (European Community for Steel and Coal) reference equations, this calculator estimates your predicted FVC based on age, gender, and height.

Lung age is a concept used to communicate lung health in relatable terms. If your lung function is reduced due to smoking or other factors, your lung age is estimated to be higher than your actual age. This calculator adjusts your estimated lung age based on pack-year smoking history, providing a tangible way to understand the impact of smoking on your lungs.

Quitting smoking is the single most effective action to protect lung health. Long-term smokers may see their lung age drop by 5–10 years within a few years of quitting. Regular aerobic exercise (jogging, swimming, cycling) also helps maintain and improve lung capacity at any age.

Frequently Asked Questions

What is FVC (Forced Vital Capacity)?

FVC is the total air you can forcefully exhale after a maximum breath. Average values are 4–5 liters for men and 3–4 liters for women, depending on age and height.

How does smoking affect lung capacity?

Smoking damages lung tissue and reduces FVC over time. Long-term smokers may have a lung age 5–10+ years higher than their actual age. Quitting allows gradual recovery.
