Taking Wall Area Measurements
The DigiRoller Plus can calculate the total wall surface area of
a room. Wall area is defined as:
([Length x 2] x Height) + ([Width x 2] x Height)
You will only need to roll a length and width, and roll or set a
height. Then you can calculate the total wall surface area of
that room. See the “Taking Volume Measurements” section
for information on rolling or setting a fixed height.
