Plan
Real rooms. Real solutions.
Pick the room closest to yours for a complete recommended setup: layout, screen, seating, and the acoustic issues to expect. Then fine-tune it with the calculators.

Small Room · 5.1
A spare bedroom or small den. Tight, but a 3.1 or 5.1 system with a 65 to 75 inch TV makes a superb intimate theater.
12 × 15
Medium Room · 5.1.2
The most common home theater room. Room for 5.1.2 Atmos, a 77 to 85 inch TV or a 100 inch screen, and a row of recliners.
14 × 18
Large Room · 7.1.4
Space for two rows, 7.1.4 Atmos, and a 100 to 110 inch projection screen. A serious theater without being a basement build.
16 × 22
Dedicated Room · 7.1.4
A purpose-built room: three rows or two generous ones, a 130 inch scope screen, and a full 7.1.4 or larger layout.
12 × 12
Small Room · 5.1
Square rooms stack their bass modes, so this one needs care with subwoofer and seat placement. Still a fine 5.1 room.
15 × 20
Large Room · 7.1.2
The classic finished-basement theater: long enough for two rows and rear surrounds, but with a lower ceiling that shapes the Atmos choice.
20 × 24
Dedicated Room · 7.1.4
A large multi-use space with a high ceiling. Needs sensitive speakers, real amplifier power, and a bright display to fill it.
