How to measure a room before a bespoke project

A bespoke project is won before the first meeting ever takes place — at the moment you measure the room. This is where a good job avoids surprises at installation: a column that arrives two centimetres too wide, a wardrobe that hits a beam, a worktop that stops short of a wall that is actually bowed. Contrary to what many believe, this is not about sheer measuring precision: it is about method. Measuring well means handing the cabinetmaker reliable references — lengths, levels, openings, squareness, neighbouring trades — that let them design realistic plans. This guide details the essential steps for measuring a room before a bespoke project, with the right tools, the right order and the most common traps to avoid.

Why reliable dimensions change everything

A custom furniture maker almost always works from the dimensions you provide before carrying out a full site survey. If those figures are approximate, the project starts at a disadvantage: production time, materials and plans are all set against values that can drift from the real site. A wall that is not square, a floor that slopes by a few millimetres, or an alcove narrower than it looks is enough to make a piece unbuildable as designed. Good dimensions do not replace a professional visit, but they speed up the whole process considerably: the designer saves round-trips, makes fewer assumptions about missing figures and can price the project far more accurately from the start. Rigorous measuring is therefore an economy, not a formality.

The basic kit: simple but reliable

You do not need to equip yourself like a workshop. The laser disto has largely replaced the tape measure for long runs, but the measuring tape still earns its place for depths and small dimensions. You will also want a spirit level (to spot a sloping floor or ceiling), a pencil, a prepared record sheet and a camera to document each zone. That modest kit is enough to produce a usable survey. Here are the tools to reach for:

• A laser distometer for the long runs (readable, fast, accurate to a few millimetres).
• A folding or long tape measure for depths, short increments and double-checks.
• A spirit level to flag floor and ceiling slopes.
• A pencil, a prepared record sheet (a plan-style sketch of the room) and your phone for photos.

The order of the survey: step by step

The key is to work in a logical order so that nothing is forgotten: start with the outline of the room, then move down to the details that matter for a bespoke project. A few simple rules structure the survey. First, draw a plan-style sketch of the room seen from above and number each wall; this prevents you confusing one measurement with another. Then take every length at floor level in both directions (length and width), but also at walking height — because few walls are perfectly parallel over their full height. Note the ceiling height (and ideally its variance), the position and dimensions of the openings (doors, windows, radiator run, service ducts, beams), the depths of alcoves and wall returns, and the nature of the floors and walls that will adjoin the future piece. Finally, record the neighbouring trades: water supply, drains, the electrical panel, sockets, switches and anything that will interfere with the installation. Here is the recommended sequence:

• Draw the plan of the room and number the walls before taking a single dimension.
• Measure each length at floor and at height (walls can be out of plumb).
• Record the ceiling height, its variations and the depth of alcoves and partitions.
• Note openings, radiators, ducts, drains and any trade next to the future piece.
• Photograph every zone and annotate the photos with the measured dimensions.

The classic traps that skew a survey

Certain errors recur constantly and explain many a job-site delay. The number-one suspect is measuring a single length: you take the width of a wall at floor level and assume it is the same everywhere, when skirting boards, projections and out-of-plumb walls shift everything. Next come measurements taken over unfinished surfaces — a floor not yet tiled, a thick underlay — which force you to state clearly at which level you are measuring. Neighbouring trades are also missed: a badly positioned water supply or an offset drain can make a piece hard, even impossible, to install. Finally, squareness gets neglected: if the walls are not at right angles, a plan drawn with perfect angles will never match reality. No survey replaces an on-site check by a professional, but avoiding these traps makes collaboration immeasurably smoother.

A good measurement is not about being as precise as possible; it is about recording what actually matters — the useful lengths, the levels, the openings and the constraints that a designer cannot guess on their own.

What the craftsman does with your dimensions

Once the survey is handed over, the maker uses it to draw the design plans, select panels and trims at the right sizes, and plan the cuts. The recorded dimensions also feed the costing: it is on the real area, radii and depths of each element that the quote is built. For this reason a well-taken survey has a direct impact on the quality of the result — fewer assumptions, less wasted rework and an installation that happens without bad surprises. Even though most workshops carry out a complementary on-site survey before production, a clean and complete record gives the project a solid starting point and shows a professional level of communication. These practices echo the housing fit-out good practice covered by the Hausinfo portal, the housing statistics of the Swiss Federal Statistical Office (OFS/BFS) remind us how strict Swiss construction standards and surfaces are, and Egger's materials resources help you understand the panels and finishes used in this kind of work.
