Humidity and Temperature Specs for Art
Relative humidity bands, temperature limits and ASHRAE types for paintings, with monitoring and material exceptions
Ideal humidity for artwork sits near a stable mid-range band, not a single magic number. This table-led guide compares CCI, Bizot, Icon, NPS and ASHRAE setpoints, then covers how to monitor the room, which materials break the mid-range rule, what museums do now and what holding a safe climate costs.
