The Plate Board Count for a Room calculator computes the number of top and bottom plate boards required for a room based on the length of the four walls and whether the top plate is doubled or single. Note: top plates are often doubled for load bearing walls. The user can choose from a list of standard board lengths with a default of 10 feet.

INSTRUCTIONS: Choose units and enter the following:

• (L) Length of Room
• (W) Width of Room 
• (bL) Length of lumber used for plate boards
• (TP) Single or Double Top Plates (doubled for strength).

Plate Boards (nP): The Plate Boards required are computed and their number returned.

The Math / Science

The plate boards are on top and bottom of a stud wall.  Typically, the top plate is doubled to carry load between studs.  However, in non-load bearing applications, a single top plate is sometimes used.
