The Room Test
Whether the mats actually fit — which is a different question from whether the floor area is enough, and the one your spare room will answer for you the hard way
The space planner on this site multiplies people by a square-foot allowance and tells you the total. It is correct arithmetic, and it ends by giving you the side of a SQUARE room of that area — the capacity reference says so in terms, that it treats the room as roughly square. Almost nobody has a square room, and a floor does not come in fractions. Capacity is a whole-number division in two directions and the remainder is simply lost, so two rooms of identical area hold different numbers of people. Held at 144 square feet: a 12 x 12 ft square takes 2 mats, a 9.8 x 14.7 ft room of exactly the same floor takes 3, and a 6 x 24 ft corridor takes 2. The square is not even the best shape — the per-person footprint is itself long and thin, so a room in roughly that proportion packs better than a square of the same area. If you are choosing between rooms, the proportions matter more than the square footage across a wide range. The sharpest case is the smallest and the most common. For a single practitioner the planner returns a room about 6.2 ft a side. A standard mat is 5.67 ft long and needs 8.11 ft once standard clearance is counted, so the recommended square holds nobody at the comfort level it was sized for: the mat goes down with about three inches spare at each end, against the fifteen that level is defined by. The mat fits. The practice does not. Nothing in the pack is invented. The clearance around a mat is SOLVED from this site's own allowances — the uniform gap that reproduces 25, 36 and 49 square feet exactly — so the pack and the planner cannot disagree about the same person, and it moves with your mat's real dimensions. The packing is grid only, with no angles and no staggering, because a place you can reach only by angling everything is not one anybody is still using in March. Also inside: what an inward-opening door and a chimney breast actually cost in places (in the worked room, nothing — and the pack says so rather than manufacturing a loss); the clearance your room really delivers against the one you asked for; and what getting the headcount from an area rule does to everything bought downstream, from props to lighting. A full page argues against the rest of it. Space planning only: this is not a fitness, medical or safety recommendation, and it is not a fire-code occupancy figure — always check capacity against local limits. It ends with a sheet of the eight lines the whole thing runs on, every one of them off a tape measure.
What’s inside
- Area is not shape — why the square-foot rule cannot answer the question you are asking
- The per-person footprint, solved from this site's own allowances rather than assumed
- The room the planner recommends, against the number of mats that fit in it
- Why the room sized for one practitioner holds nobody at the comfort it was sized for
- Your own room measured, with the orientation and layout that fits most
- The same floor at five different shapes — and why the square is not the best one
- What an inward-opening door and a fixed obstruction really cost in places
- The clearance your room actually delivers, against the one you asked for
- What taking the headcount from an area rule does to props, storage and lighting
- What this does not settle, stated plainly
- Your own numbers — the eight lines the pack runs on, and the order to measure in
Run one of the free calculators first and buy from that page, and this sheet is computed from your own figures. Buy from here and the pack still arrives complete — the sheet simply has no numbers of yours to work from yet.
