Home gym calculators
A home gym is a dimensions problem before it is a shopping problem. These tools answer the measurements first: what fits under your ceiling, what fits in your room, what your floor needs, and what the whole build actually costs.

Where to start
Start with the ceiling height calculator. Ceiling height is the constraint that decides the build, it is the one almost nobody checks before the rack arrives, and it is the only one you cannot buy your way out of. It takes your height and your lowest measured clearance and tells you which lifts fit and which rack heights are available to you.
Once the height works, the gym space planner handles the floor. The number people underestimate is not the rack footprint, it is the clearance around it: a 7 foot barbell is 86.6 in long, so any barbell lift needs at least 9 ft of clear width no matter how compact the rack is.
After that the order is floor, then load, then budget. The flooring calculator sizes the rubber and tells you how much weight the floor itself is adding, which matters over a suspended basement floor. The build cost calculator totals the whole thing and shows the payback against a gym membership.
These tools are researched planning aids, not coaching and not structural engineering advice. Anything you bolt into a floor or a wall must be checked against the actual structure, and if you are not certain, get a licensed professional involved before you drill. See our rack anchoring guide for what that actually involves.
