The Five-Centimetre Problem: A Tape-Measure Walk-Through Before Moving Day

It is almost never the packing that sinks a move. It is a doorway. Four people holding a two-seater sofa at an angle on a half-landing, someone insisting it went in fine at the old house, and a clock that has suddenly got very loud.

The uncomfortable truth? That moment was decided weeks earlier, when nobody measured anything. Most quotes are built from a room count and a postcode. That is enough to guess a van size and a crew — and it is exactly how a job ends up with the wrong vehicle, two people instead of three, and a sofa parked on the pavement while everyone has a think.

Twenty minutes with a tape and your phone camera closes that gap. Here is how to spend them.

Start at the kerb, not at the sideboard

Walk the route your biggest item will take, in the order it will take it: parking space, kerb, path, gate, front door, hallway, stairs, landing, destination doorway, final position. Do the new place first. That is where the surprises usually live, because you have spent months looking at your own hallway and no time at all looking at theirs.

Film it. A single continuous phone video from the pavement to the back bedroom tells a removals surveyor more in ninety seconds than a paragraph of description ever will.

Measure the clear opening, not the door

This is the mistake almost everyone makes. A 76cm door does not give you a 76cm gap. Open it ninety degrees and measure between the frame stops — the actual hole the furniture has to pass through. Then subtract anything in the way: a door closer, a radiator, a handrail, chunky skirting, a stair gate bracket.

Do the same for every internal doorway on the route, and note the narrowest one. That single number sets the ceiling on what goes through whole.

Stairs: the turn is the trap

Straight flights are rarely the issue. It is the quarter-turn with a winder, the half-landing with a low ceiling, the spiral in a converted flat, the banister that eats 15cm of width at hip height.

Measure the width of the tread at its narrowest point, the headroom above the turn, and the depth of any landing. If a sofa has to stand on end to get round the corner, that is a fact worth knowing before the crew discovers it.

Lifts, weight limits and the sixth-floor conversation

Flats add a layer. Get the internal dimensions of the lift with the doors open, plus the door height. Then find the weight limit — it is usually on a plate inside the car or in the lobby. A loaded two-seater sofa plus two movers can push a small passenger lift harder than you would think.

Ask the building manager about booking a lift, protecting the lobby, permitted hours, and whether the fire doors need to be propped (usually they must not be). A five-minute call to the managing agent can save an hour of standing about on the day.

Kerb to door is a real distance

Count the steps, measure the path width, note the surface — gravel, uneven flagstones and a steep ramp all slow a trolley down. Check whether the gate is wide enough for a sack barrow, and whether there is a step up at the threshold. Then check where a van can legally stop and for how long. Nobody wants to discover a school-run parking restriction at 8:40am.

The awkward-item inventory no quote form asks about

List the things that are heavy, tall, glass, or oddly shaped: American fridge-freezer, piano, wardrobes, bed frames, treadmills, aquariums, large planters, mirrors, artwork, that sideboard inherited from a grandparent that weighs as much as a small car. Against each, write whether it dismantles, and whether you still have the fixings.

The twenty-minute checklist

Print this, or copy it into your notes app and tick as you go.

• Clear opening width of the main entrance (door open 90°, frame to frame)
• Narrowest internal doorway on the route
• Hallway width at its tightest point
• Stair width at the narrowest tread, plus any turn type (straight, quarter, half-landing, spiral)
• Headroom above the stair turn
• Landing depth
• Lift: internal width, depth, door height, weight limit, booking rules
• Steps from kerb to door, path width, surface, gate width
• Parking: restrictions, yellow lines, permit zone, suspended-bay options
• Communal door codes, fobs, concierge hours
• Awkward-item list with dismantle notes
• Photos with the tape measure in shot at each pinch point
• One continuous video walk-through of both properties

Handing it over without a forty-email chain

Send the video, a short list of measured numbers, and the awkward-item notes in one message when you request the quote. Then ask five questions:

1. What vehicle size does this suggest — 3.5-tonne, Luton, or larger?
2. How many crew, and does that change with the fridge-freezer?
3. Is there an access charge, a long-carry charge, or a parking suspension to arrange?
4. Who handles anything that will not fit — dismantling, door removal, hoist, or storage?
5. Does the route touch a clean air zone or congestion charge, and is that in the price?

Firms quote faster and more accurately when the geometry is already on the table. Sometimes the answer is a smaller van and the same crew, which is money back in your pocket.

When the numbers say no

If something genuinely will not go, you have options: take the door off its hinges, remove a window sash, dismantle further than feels reasonable, book a hoist, or move it into storage and sell it later. All of these are cheaper and calmer when decided a fortnight out rather than at 10am on the day.

If you only do three things

Measure the narrowest doorway, the tightest stair turn, and the lift. Those three numbers predict most of the pain. Everything else on the checklist is polish — useful polish, but polish all the same.

The twenty minutes you spend now is the difference between a move that flows and a move that stalls in a stairwell with four people, one sofa and no plan.
