What railing height do I need?
The minimum height necessary for railing is 36” in most residential applications. However, some areas may require the higher 42” railing that is required for commercial applications. Other reasons for choosing 42” high railing over 36” high railing is that the top rail is generally above eyeline when seated on a deck allowing for an unobstructed view. It also allows for a greater wind barrier or for more privacy (with the option of frosted glass).
