Try itPlan Before You Build
These five calculators turn the guesswork of planning a man cave into numbers you can act on. Each one takes your room dimensions or your budget and returns specifics: what fits, what it costs, where the speakers go, and how many lumens you need.
Every tool runs on the same research behind our reviews and guides, with clearance math, real budget ranges, and industry standards like SMPTE, THX, and CEDIA built in. You see the reasoning behind each result, not just a single number, so you can adjust the inputs and watch the answer change.
Run the numbers before you spend, and you catch the costly mistakes on screen instead of after delivery: the pool table that leaves no room to shoot, the projector throw that overshoots the wall, the sound system that swamps a small room.
