Bonus Tip
Measure Twice: Use the 1.5x Rule for Any Space
Convert feet to inches, divide by 1.5 for max 4K size—e.g., 9 ft (108 inches) fits 72-inch TV perfectly.[3] Cross-check with charts: If over room limits, drop 5-10 inches to avoid overwhelm. This ensures 30-degree optimal viewing 95% of the time.[1][5]
