The Earth's atmosphere is composed of the following gasses:
Oxygen (O2) - 21%
Nitrogen (N2) - 78%
Argon (Ar) - 1%
Carbon Dioxide (CO2) - 0.038%
Water (H20) - varies from 0 - 4%
Neon (Ne) - 0.0018%
Helium (He) - 0.000524%
Methane (CH4) - 0.0002%
Krypton (Kr) - 0.000114%
Hydrogen (H2) - 0.00005%
Nitrous oxide (N2O) - 0.00005%
xenon (Xe) - 0.0000087%
Thus, water vapour can make up as much as 4% of the Earth's atmosphere.
