Room and storage
A walking pad for a small room: measure two footprints
A walking pad for a small room has two footprints: the one used during a walk and the one left after it. Decide which of those is the actual constraint. Folding and shortness solve different problems.
When open length is the problem
If a long machine would block a door or extend into a walkway, begin with open dimensions. The Egofit M1 has a documented 38.39 inch body, while the M2 is 41.5 inches long. Both use shorter belts and fixed inclines. Their compact open size is a deliberate compromise, not a way to preserve every property of a longer deck.
Measure how far the front can extend under the desk and what remains behind you. Inspect baseboards, braces and power cords. Do not assume the full length can disappear below a desktop when a horizontal support blocks the front of the machine.
When storage length is the problem
A half-fold deck can give you a long walking area during work and a shorter object afterward. The P1 is listed at 56.5 inches open and 32.5 inches folded. The C2 has a 32.5 inch folded length, with its own width and height. Compare all dimensions instead of shopping on folded length alone.
A sofa opening might be high enough at the front but blocked farther in by a support. A rug can reduce usable clearance. Check the route and the final resting position, and allow room to control the machine while rolling it. A published dimension is not a recommendation to force the body through an opening with no practical margin.
Read the dimension label
Shipping-package size is not machine size. WalkingPad's general comparison gives the Z1's packaging dimensions in a folded-size position, while the product table identifies the smaller folded machine. The Z3 repeats open dimensions under its folded label, and WalkingCase inch/mm values disagree. Those are reasons to request clarification, rather than borrowing a convenient figure from another model.
The finder leaves a precise fit unconfirmed when the underlying size is unresolved. You can still investigate the model, but a physical opening is too concrete a requirement to answer with a guess.
Plan the daily changeover
Put the chair somewhere, place the treadmill, reach the remote, finish the walk, store the machine and return the chair. If that sequence requires lifting a heavy unit across the room every time, a compact specification may not make the routine convenient. The WalkingCase's casters and handle address movement differently from a simple two-wheel deck, but stairs and thresholds remain separate problems.
Use the optional body and folded-height limits to narrow documented fit, then compare the complete handling routine in each review.
