The Wall Stud Count calculator computes the number of studs (e.g. 2x4s) needed to build a wall based on the length of the wall and spacing. 

INSTRUCTIONS: Choose units and enter the following:

1. (L) Length of Wall
2. (oC) on-center spacing of studs.  The default is 16".

Wall Stud Count (nS): The calculator computes the number of studs needed for the wall.  Note: this number of studs does not include the base nor top plates since longer boards are often used for those.
