Quote:

Your dimensions should always be in 4’ increments whenever possible because all your sheet goods, dimensional lumber and even floor coverings are standardized with the four foot rule.



Regarding this, it is true, however, you do not want to have a room where the width and length are divisible by the same number. Eliminating room nodes will help immensely with the "demo" theatre you are trying to produce. It will help you save on room treatments as well.

From ethan winer:

"There are a few "ideal" ratios of room height, width, and length that professional studio designers agree should be used if possible. Three of these ratios, developed by L.W. Sepmeyer, are shown in Table 2.

Height Width Length
1.00 1.14 1.39
1.00 1.28 1.54
1.00 1.60 2.33

Table 2: The ideal room has a ratio of height, width, and length similar to one of these.

Using these ratios, you will get a really good sounding demo room, and all you have to do is change your layout a bit. Ethan also has a room node calculator here that you can use to see if your room will produce alot of standing nodes or not. In my opinion, it is worth designing a demo room that will eliminate the most nodes as possible.

Good luck.
