Other than the standard 32" inch height for a chair rail, what is the height for a chair rail going into a nursery that will be higher?

They are usley set at 40" to45" ,it depends on just how high your baby furnt. Is

Is the chair rail being used to protect the room's walls from baby furniture or simply decorative? A functional rail should be installed after you have the furniture's heights. For decorative value use the same height as used in other rooms of the home. Good luck.

Standard is 36" after that weve installed it at 42" and 48"
