Refrigerator Doorway Fit: Will It Actually Go Through?
A doorway-only check for a refrigerator: how the appliance box meets the clear opening, why the packaging and the removed doors change the object you should be measuring, and what a narrow pass of a few centimetres really tells you.

The question
Will this refrigerator physically pass through my doorway in one of the tested poses — and what does a narrow pass, or a refusal, actually tell me about the rest of the delivery?
Short answer
Compare the appliance box against the clear opening, not against the appliance’s marketing width. Measure the state that will be carried: a boxed appliance is bigger on every edge, and doors and handles are usually removed for transit, which makes it smaller. Then check the pose: a refrigerator almost always travels upright, so its width and depth meet the opening width while its height meets the clear head. A pass of a few centimetres is a real pass, but it assumes the appliance is carried through straight and level — the turn into the room, the stairs and the door leaf are not in the model.
Why this happens
The object you measure is not the object on the spec sheet
A refrigerator is specified by its cabinet width, but the thing that goes through the door may be a boxed unit on a pallet, or a bare unit with the doors and handles removed. Those are three different objects with three different widths, and the difference between them is often larger than the margin you are worried about.
Decide first which state will actually cross the threshold, then measure that state. Measuring the cabinet and then discovering the packaging adds a hand’s width is the most common way this calculation gets wasted.
Height and depth, not just width
Most domestic doorways are generous in height, so the width comparison usually decides the outcome. But a refrigerator is tall and deep, and both of those numbers matter in ways people forget: the depth is the dimension that has to clear a hallway turn, and the height has to clear a lowered head, a door closer or a decorative frame.
In the upright pose the engine compares the appliance width with the clear width and the appliance height with the clear height, and reports both remainders. A positive width remainder with a negative height remainder is a real and common result, and it is worth reading both rows rather than the verdict alone.
What a narrow pass does and does not promise
A pass with sixty millimetres to spare means the box clears the section by sixty millimetres in the tested pose, carried straight and level. That is a genuine answer to a genuine question, and it is more than a spec sheet can tell you.
It is not a promise about the rest of the route. The engine declares PATH_NOT_MODELLED, so stairs, corridor turns, the room door leaf and the final in-room manoeuvre are all outside it. Nor does it decide whether the appliance may be laid down during transport — that is a manufacturer requirement about the compressor, and it belongs in the manual, not in a geometry check.
Step by step
- 01
Measure the clear opening, not the door
Take the narrowest clear width across the opening and the lowest clear head height. A door leaf, a frame rebate and a threshold all reduce the number that matters; the leaf width on the packaging of the door is not the clear opening.
- 02
Measure the appliance in its travelling state
If it arrives boxed, measure the box. If the doors and handles come off for transit, measure the carcass with them removed and note the handle projection separately so nothing gets silently dropped.
- 03
Confirm the transport orientation with the manual
Refrigerators are commonly required to travel upright, and the settling time before power-on is a manufacturer instruction. The calculator will happily test any of the six poses; the manual decides which poses are allowed.
- 04
Read both remainders, then the reasons
Check the width and height remainders against the opening, and read the reason codes. If the result says the doorway needs a pose change, that is the engine telling you the upright pose is not the one that clears.
Worked example: a 700 mm appliance through a 760 mm opening
An appliance measures 700 mm wide, 700 mm deep and 1800 mm high. The doorway clears 760 mm by 2000 mm with a 120 mm frame, and the destination room is 2800 × 3600 × 2400 mm. No extra margin is requested, and the upright pose is selected. These are inputs; the table below is the live engine result for exactly these numbers.
Input data
| Item | Refrigerator |
|---|---|
| Length | 700 mm |
| Width | 700 mm |
| Height | 1800 mm |
| Clear width | 760 mm |
| Clear height | 2000 mm |
| Frame depth | 120 mm |
| Room width | 2800 mm |
| Room length | 3600 mm |
| Room height | 2400 mm |
| Extra clearance | 0 mm |
| Selected pose | Upright |
Calculation process
- 01All dimensions are in millimetres. In the upright pose the 700 mm appliance width is compared with the 760 mm clear width and the 1800 mm height with the 2000 mm clear height; the same box is then compared with the room volume on all three axes.
- 02The width remainder is small but positive. That is what a tight domestic delivery looks like on paper: the appliance clears, and it clears by a margin you would notice while carrying it. No margin was requested here, so none is subtracted.
- 03The status and rows below come from that one engine result. They assume the appliance is carried through straight and level in the selected pose, and they say nothing about the hallway turn, the stairs or the room door leaf.

Calculation version 2.0.0
Applicable range
One rigid rectangular appliance, one doorway section, one rectangular room, and one pose. A transit geometry check, not a delivery plan and not an installation approval.
Limits of this example
- Packaging, pallets and straps are separate objects; measure the state that actually travels.
- Removed doors and handles are not modelled — you must supply the carcass dimensions you intend to carry.
- Stairs, corridor turns, the room door leaf and in-room manoeuvring are not modelled.
- Transport orientation and settling time are manufacturer requirements, not geometric ones.
- Ventilation gaps, door-swing arcs and services are outside this page entirely.
Formulas used
Section check in the chosen pose
W_box(pose) + C_requested ≤ W_clear and H_box(pose) ≤ H_clear
Both rows must be read. A width pass with a height shortfall is still a refusal at that pose.
Box extents of a rotated pose
h_box = |R| · h
Six axis-aligned poses only. "It would go through on the diagonal" is not something this number confirms.
Total margin to share between both sides
M_total = W_clear − W_box(pose) − C_requested
A total figure, not a per-side allowance. Centring the appliance halves it, and nothing in the model keeps it centred while you carry it.
Scope and limits
- The engine is dimension-only: BOUNDING_BOX_ONLY, SECTION_ONLY, STATIC_VOLUME_ONLY.
- No product database and no brand or model comparison; all dimensions are yours.
- PATH_NOT_MODELLED / ROOM_PATH_NOT_MODELLED / DOOR_LEAF_AND_OBSTACLES_NOT_MODELLED are standing limitations.
- Only six axis-aligned poses are tested; no continuous-angle search.
- A geometric pass is not an installation approval — ventilation and door swing are separate requirements.
Common mistakes
Measuring the cabinet when the boxed unit travels
Packaging adds width on every edge. If the appliance arrives boxed, the box is the object that has to fit.
Reading only the width row
A low head or a deep frame can fail the height comparison while the width looks comfortable. Read both remainders before concluding anything.
Treating a tight pass as a comfortable one
Sixty millimetres of total margin is a pass, but it leaves thirty millimetres per side if the appliance stays perfectly centred. Real carrying is not that precise.
Assuming the calculator decides the transport orientation
It will test any pose you select. Whether the appliance may be laid down is a compressor question answered by the manufacturer, not by geometry.
Run the fit calculator
Enter the appliance in its travelling state, the clear opening and the room, then read the width and height remainders separately. That is the doorway question answered with your own numbers — the installation clearances are a different page and a different responsibility.
