Measure the height
Holding the device at a fixed point, aim it at the ceiling.
measurement to the ceiling = 1.59m + (turn the device at the same fixed point and measure to the floor)
measurement to the floor = 1.2m
=a total room height of 2.79m
Measure the width
They measure a wall next from a fixed point:
Measurement to a wall= 3.2M +
Measurement to the opposite wall=3.12M
=a total room width of 6.32
Measure the length
Finally they measure the length of Mel's Tavern from a fixed point.
Measurement to a wall= 3.9M
+ measurement to the opposite wall=3.66M
