Put the walking route down first, before anything else touches the floor. Whatever narrows the path between the two doors is the thing that gets moved, and once it has been moved twice it lives in a cupboard.

That is the method for a room that has to stay a bedroom or a living room. Layout guides assume a spare room, so they say keep the middle clear and line the walls with gear. In a shared room the walls are the scarce thing: one has the window, one has the wardrobe, one has the radiator and the door, and the fourth is behind the sofa. What is left over is where the mat goes. This page assumes the measuring is done; if it is not, that is measure your space before you buy.

Chalk the route, then place against what is left

Walk the room the way you actually cross it: door to door, door to window, door to the side of the bed you get out of. That path is not negotiable and it is not yours to spend.

There are two figures to hold it against. Residential code sets a hallway at not less than 3 feet, 914 mm (IRC R311.6). Accessibility standards ask a door opening for 32 in of clear width, 815 mm. Neither governs a living room, so treat both as references rather than as rules about your floor. What they are useful for is scale, because they are narrower than people guess. The path you owe the room is roughly a metre, not two.

I would tape the route before placing anything. Everything below is arranged in the leftover.

Measure the leftover rectangle and the tool below names what clears it, and which single dimension rules out each thing that does not.

What fits your clear floor zone

Enter the clear floor zone you can give a workout. The list updates as you type and names the dimension that rules each option out.

Fits

    Does not fit

      FitVilo model - based on published figures. See methodology.

      If the room sits above somebody, the tools page carries an impact-risk planner that ranks a session the way this page ranks a placement.

      The five placements, in the order they happen

      The mat goes lengthwise along the longest unbroken wall. Longest, and unbroken: a wall with a radiator halfway along it is two short walls. Long edge to the skirting gives you the most arm reach in the direction you have most of, and it keeps the mat parallel to the route rather than across it.

      The dumbbell tray goes at the foot of the mat, against the skirting, cradle to the wall. Handles into the room, so you are not reaching over the tray to lift. At the foot rather than the head, so it sits outside the arc of anything pressed overhead. Floor level beside the mat is generally the only place an adjustable pair goes anyway: a BowFlex 552i handle stands 22.8 cm tall, so put a tape under the bed at the lowest rail before assuming it slides away. Stored size in full is in equipment storage.

      The folding bench lives flat against a wall, outside the door swing. Open the door slowly and mark where the leaf reaches; the radius is the width of your own door and nothing published will tell you what it is. Anything fixed inside that quarter-circle gets kicked the first time somebody opens the door mid-session. In use, point the head end into the room so you stand up into open floor.

      The band anchor goes where the band crosses open floor, not open air. Facing the long axis of the room rather than a corner, so a row has somewhere to go. Anchoring in a rental is its own problem and it is worked through in anchoring resistance bands without drilling.

      The walking pad goes cord-end nearest the outlet, and never with the cord crossing the mat. This is the one placement on the page with a real hazard attached, and the socket decides it. Outlet heights are trade convention rather than code, usually 12 to 16 in to the bottom of the box. The NEC sets no height for general-use receptacles at all. So find yours and plan the cord run around it, rather than memorising a band. Folded, an A1 Pro is 82.2 by 54.7 by 12.9 cm, and the 12.9 cm is what decides whether it slides under anything.

      Go up the wall, in bands

      A small room runs out of floor long before it runs out of wall, so the wall does the storing.

      Heavy and stored things go low, at knee height or below: the tray, the folded bench, a basket of bands. Session things go at waist height on a small shelf, water and a towel and a phone. Eye level takes a hook and a small mirror if you use one. Above head height, only what gets touched once a session, and nothing at all above the spot where you press.

      Which container suits which category is a separate question and the answer is in organize fitness gear in a small apartment. The point here is only the height band, because in a shared room visible storage at the right height is what keeps the reset short enough to bother with.

      The tall thing that probably does not fit

      One category is ruled out by the ceiling rather than by any of the above, and the published numbers make it quick.

      Measured freestanding pull-up and dip towers run 158 to 208 cm at full extension. Their bases are 73 by 80, 76 by 80 and 106 by 95 cm. The seller’s own rule is to pick one roughly 42 to 45 cm above your own height, set so your fingertips just barely touch.

      Hold that against the clear height where it would stand. That is usually a light fitting rather than the ceiling. No room to get a hand over the bar means a doorway bar instead, and the ceiling veto in full is in workout corner without a spare room.

      Three placements that undo the room

      In front of the only window. I would give up the wall before I gave up the daylight, every time. The window is worth more to the room than the gear is, and the gear can go somewhere else.

      Across the route. Covered above, and it is the one that ends routines rather than merely annoying people.

      Inside the door swing. A tray, a bench edge or an anchor strap in the arc gets scraped, and the scrape is on a rented door.

      When none of the walls work

      Some rooms have no wall to give. Unroll your own mat against the longest run you have. If it will not lie flat without meeting a radiator or crossing the route, that is probably your answer.

      I would then site a session rather than equipment. A rolled mat that comes out and goes back, bands on a hook, and the heavy work done elsewhere or outside. Test it for a fortnight before buying anything that needs a permanent spot.

      One thing this page will not tell you is where a treadmill should stand relative to your joists, or which of your walls is load bearing. An earlier version did, and that was wrong, because neither is establishable from inside a finished flat. A heavy machine going onto an upper floor is a question for the building documents, the landlord or a structural professional. What a covering under it does and does not do is in home gym flooring, and what the flat below hears is in quiet apartment workouts.

      Lay the tape, walk the route, put the mat in the leftover. If you have a medical condition or injury, talk to a clinician before training.
