How this works out clearance

Last updated 9 September 2026

This page explains exactly what the service does, what part of it is a calculation and what part is not, and where it stops. It is worth reading once before you rely on anything it tells you.

What it does

It works out, from measurements you take yourself, how much clearance is left at each narrowest point along a route, which point stops an item, and whether carrying it flat, on its side or upright gets it through.

This is not a guarantee, and it is not an assessment of any actual move.

The geometry runs in your browser: the clear width of an open doorway, the longest object that can be swung round a right-angle turn, the arc something sweeps as it comes upright on a landing, and the two conditions a lift imposes at the same time. A language model is used for one thing only — reading your sentence and deciding which of the four route types you have. It does not calculate anything, and no number on your screen came from it.

Clearance is a range, not a figure

Every clearance is given as a band, and there is no setting that turns it into a single number. There are good reasons for that:

  • Door frames are not always square, and floors are not always level.
  • Handles, feet and castors often stick out further than the main body.
  • A tape measure read by one person, across a wide span, has a real margin in it.
  • The packaging is always larger than the item. The box is bigger than the thing. Retailers usually quote the unpacked size, and handles and feet often stick out further than the main body. Check the packed dimensions before you decide.

Where the clearance is small, the service says so and stops there: “This is close enough that it depends on things a measurement cannot settle. Treat it as “maybe”, not “yes”.” It does not turn a close call into a yes.

There are no product dimensions here

The service holds no product dimensions whatsoever — no brand, no model, no size. Every measurement comes from the retailer’s own specification or from you.

This does not hold product dimensions. Take them from the retailer's own specification — and take the packed size, not the unpacked one.

Nothing is looked up, recommended or compared. Product data changes constantly and varies between markets, and writing it down here would amount to inventing it.

No alterations, no lifting, no structural judgement

The service gives no advice about alterations of any kind and makes no structural or load-bearing judgement. Removing a door frame, a window or a wall, or lifting something in from outside, must be assessed on site by a qualified person. When it detects any of that in what you have written, it stops and says so:

Anything that involves removing part of the building, or lifting something in from outside, has to be looked at on site by someone qualified. This only works out whether it goes through as things are.

It gives no handling advice of any kind either:

How to lift something, how many people it takes and how to carry it are matters of personal safety, and they are outside what this works out. This only measures whether the shape goes through the space.

It recommends no removal firm and provides no quotation or introduction.

What it cannot know

  • The real size of the item. Whatever the retailer publishes is a description, not a measurement of the one that turns up.
  • Whether the handles, feet or castors come off, and how much they take off the overall size when they do.
  • How square the door frames are, how level the floors are, and how much the skirting eats into the opening.
  • How accurately you read the tape, and whether you held it level across the full span.
  • What the packaging adds, which is almost never published alongside the product size.

This list is shown alongside every reading rather than kept on a policy page, because it is part of the answer rather than a disclaimer about it.

Your data, and training

The dimensions and route descriptions you enter are used to produce your reading and, on the Movein plan, to let you reuse a route. They are not used to train any model, ours or anybody else’s.

There is no image upload on this service. Estimating a size from a photograph cannot be accurate, and the whole value of this rests on the numbers being ones you took yourself. See the privacy notice for everything else about your data.

High-risk uses are prohibited

A reading must not be relied on for medical, legal, financial, safety-critical, employment, credit, housing or judicial decisions. The full list is in the acceptable use policy.
