The ideal relative humidity for health and comfort is somewhere between 30-50% humidity, according to the Mayo Clinic. This means that the air holds between 30-50% of the maximum amount of moisture it can contain.

How do you calculate humidity with temperature and dew point?

When given temperature and dewpoint, the vapor pressure (plugging Td in place of T into Clausius-Clapeyron equation) and the saturation vapor pressure (plugging T into Clausius-Clapeyron equation) can be determined. The RH = E/Es*100%.

How can I measure the humidity in my home?

The easiest way to measure your indoor humidity level is by using a hygrometer. A hygrometer is a device that serves as an indoor thermometer and humidity monitor.
