What's the estimated length of a wall that has 31 studs 16 inches on center?

480 inches (40 feet)

Explanation:

Studs are boards placed on walls so as to support the walls. Studs are used in framing the wall and they are vertical.

Studs are usually spaced on walls with wall framing at either 16 inches on center, 19 inches on center or 24 inches on centers.

Given that on center spacing = 16 inches, number of studs = 31

The length of the wall is given by the formula:

number of studs = (length of wall in inches / on center spacing in inches) + 1

Length of wall (inches) = (number of studs - 1) * on center spacing

hence:

Length of wall (inches) = (31 - 1) * 16 inches = 480 inches

Length of wall = 480 inches = 40 feet
