Measuring Up ... the width
Starting with Wall 1.

Measure the total width in
three places.
a) At floor level
b) At ceiling level
c) At mid level.
The three measurements will all
be slightly different.
Note we will be using
... the smallest measurement
of the three.
Now repeat with Walls 2, 3, and 4 by measuring the total widths in the same three places ... and then make a note of the "smallest" measurements on your plan outline.
Moving on to [ Height ] will show how to measure the bedroom ceiling height correctly ...
