StairMaster Dimensions & Weight UK (2026): Will It Fit Through the Door?

A StairMaster 4G Gauntlet measures 137 × 74 × 163cm and weighs 158kg. The 8Gx Gauntlet is 147 × 86 × 200cm and 231kg, the 10G Gauntlet 160 × 86 × 206cm and 279kg, and the FC 8 Series FreeClimber 110 × 69 × 173cm and 85.4kg. Those are StairMaster's current manufacturer figures.

The short answer: the width decides whether a StairMaster gets through your door. A standard UK internal door is 762mm wide, and its usable opening is narrower than that. An assembled 8Gx or 10G (86cm wide) will not pass through one; a 4G (74cm) or FreeClimber (69cm) may, but only if you measure the clear opening first. The weight decides how many people, and what equipment, the delivery needs.

What are the dimensions and weight of each StairMaster?

These are the manufacturer's current figures from StairMaster's product sheets. The narrowest dimension is in bold because it is the one that decides whether a machine goes through a doorway.

The three Gauntlets are StepMills: a revolving staircase with real moving steps. The FreeClimber is a different kind of stair climber, with two independent pedals on a linkage, which is why it is so much lighter and more compact.

Height matters for the room as well as the route. Recommended ceiling heights are covered separately in our StairMaster ceiling height guide.

Will a StairMaster fit through a standard UK door?

It depends on the model and on the clear opening, not the door size printed on the label. The most common internal door in England and Wales is 1981 × 762mm, according to door manufacturer JB Kind's standard door size guide.

The usable gap is smaller than the door leaf. Approved Document M, Volume 1 measures "clear opening width" from the face of the open door to the frame or stop on the other side, and its minimum for a new home is 750mm with a 900mm corridor approached head-on.

Height is the second constraint. A standard door leaf is 1981mm tall, while the assembled 8Gx stands 200cm and the 10G 206cm. Neither passes upright through a standard doorway, so tell us your door sizes before choosing pre-assembled delivery.

Is a boxed StairMaster easier to get in than an assembled one?

Not always. StairMaster's 4G owner's manual lists the boxed machine at 125 × 76 × 109cm and 197kg, so the box is 2cm wider than the assembled 4G and 39kg heavier.

The FreeClimber's owner's manual gives a box of 117 × 76 × 113cm, again wider than the assembled machine. Packed dimensions can differ from the assembled footprint, so access should always be checked against the delivery configuration before ordering. For the 8Gx and 10G, contact us with your access measurements and we’ll confirm the appropriate delivery and installation option.

Sport England's Fitness and Exercise Spaces design guidance makes the same point for gyms: "Doors and corridors should be designed to accommodate the equipment in transit, taking into account additional bulk due to protective packaging."

Which delivery option suits a tight access route?

Choose by your narrowest point. We offer three options on every StairMaster, and each puts different demands on the route in.

Installation is arranged before you order and quoted separately. Send us the route measurements when you enquire and we will tell you which option works.

How heavy is a StairMaster to move?

Too heavy for any one person, and too heavy for two to carry casually. The HSE's Manual handling at work guide gives 25kg as the guideline figure for a man lifting close to the body at knuckle height, and states that these guidelines "are not 'safe limits'".

Against that, the lightest machine here, the FreeClimber, is 85.4kg. The 4G is 158kg, more than six times the guideline, and the 10G ships at 372kg. These are jobs for trolleys, stair-climbing equipment and a trained crew.

At work the duty is explicit. The Manual Handling Operations Regulations require employers to avoid hazardous manual handling so far as reasonably practicable, so a gym taking delivery should plan the route with its delivery provider rather than rely on staff to carry the machine in.

How do you measure the access route before ordering?

Walk the route from where the vehicle will park to the machine's final position, and write down five measurements.

1. Every doorway's clear opening. Open the door fully and measure from the door face to the stop opposite, as Approved Document M does. Note the height too.
2. Corridor widths at each turn. A 137cm-long 4G has to swing round a corner, so a narrow hallway with a right-angle turn can stop a machine that clears every door.
3. Steps and stairs. Count them, note any turn or half-landing, and check the handrail and ceiling clearance at the top.
4. Lifts. Internal car dimensions, door width and the rated load, which must cover the shipping weight plus the people moving it.
5. Thresholds and surfaces. Gravel drives, lawns, steep ramps and raised thresholds all slow a heavy trolley.

Photos of each pinch point help as much as the numbers. Once the machine is through the door, the floor, power and space it needs are covered in our StairMaster room setup guide.

Which StairMaster is easiest to get into a house?

The FC 8 Series FreeClimber, then the 4G Gauntlet. The FreeClimber is the narrowest (69cm), the shortest (173cm) and by far the lightest (85.4kg), because it uses independent pedals rather than a full revolving staircase.

If you want a StepMill specifically, the 4G is the model built for homes. It is 12cm narrower and 73kg lighter than the 8Gx, and its 2.44m recommended ceiling suits standard UK rooms. Our best StairMaster for a home gym guide compares the two in full.

The 8Gx and 10G belong in commercial spaces with double doors, loading access and 3.05m ceilings. The complete StairMaster buyer's guide covers which model suits which facility.

What does our own order data show about access?

That buyers pay to have it handled. Our most recent StairMaster order, in September 2026, was a StairMaster 4G Gauntlet with the 10" LCD console, and the buyer added pre-assembled delivery and installation to the same order.

The 4G is the model a home access route is most likely to take, and even so the buyer chose not to manage a 158kg machine themselves. Our advice matches that choice: confirm the route first, then let the delivery crew deal with the weight.

How is a StairMaster delivered?

Free UK delivery on every StairMaster. Orders are dispatched within 5 working days, with tracking emailed within 24 hours of dispatch, and delivered across UK mainland by our delivery partners.

You can choose courier delivery ready for you to assemble, pre-assembled delivery that arrives built, or full installation arranged on site. Installation is arranged before you order and quoted separately.

Frequently asked questions

How wide is a StairMaster? The StairMaster 4G Gauntlet is 74cm wide, the 8Gx and 10G Gauntlets are both 86cm wide, and the FC 8 Series FreeClimber is 69cm wide. Width is the dimension that decides whether a machine fits through a doorway, so compare it with the clear opening of the narrowest door on your route, measured with the door fully open.

Will a StairMaster 8Gx fit through a house door? Not assembled through a standard internal door. The 8Gx is 86cm wide and 200cm tall, while the most common UK internal door leaf is 762mm wide and 1981mm tall. It needs a wider entrance such as double doors, patio doors or a garage door. Ask us about the packed dimensions and installation before ordering one for a house.

How many people does it take to move a StairMaster? More than one person can safely carry, whichever model you choose. The lightest, the FreeClimber, is 85.4kg; the 4G is 158kg and the 10G ships at 372kg. HSE guidance gives 25kg as the guideline for a man lifting close to the body, so these machines are moved with trolleys and a trained delivery crew.

Can a StairMaster go upstairs? Sometimes, but plan it with us first. The staircase width, any turn or half-landing, headroom at the top and the floor structure of the upstairs room all matter. The FreeClimber at 85.4kg is the most practical upstairs option. For a Gauntlet on an upper floor, have the floor loading checked and choose full installation arranged on site.

Does the StairMaster box fit through a door more easily than the machine? Not necessarily. The 4G's box is 125 × 76 × 109cm, 2cm wider than the assembled machine, and weighs 197kg against 158kg. Packaging protects the machine but adds bulk. Compare both the assembled and boxed sizes against your route, then choose between courier, pre-assembled delivery or installation.

What if my access route is too narrow for any StairMaster? Tell us the measurements and we will check the options with you before you order. The FreeClimber is the narrowest model in the range at 69cm. If nothing in the range suits the route, we would rather say so than send a machine that cannot reach the room.
