Decide what the measurements are for
An initial enquiry needs different information from a material order or cutting specification. Note the intended work: replacing flooring, positioning furniture or replacing a door. Measure the relevant visible areas and label your figures as preliminary.
IKEA’s kitchen-planning process, for example, distinguishes an initial rough floor plan from the precise dimensions supplied by its measuring service, which are then used to update the plan. Agree the necessary checks for your project with your own contractor.
Distinguish measurements you took yourself, estimates and figures from old plans. State whether they describe the room today or a proposed finished condition. An existing floor plan can help, but its date does not establish that the dimensions still match the room.
Draw a sketch with clear measurement points
Sketch the room from above. For a room with four corners, label them A, B, C and D clockwise. The wall sections are then AB, BC, CD and DA. Add letters and rows for additional corners. Mark doors, windows and recesses on the relevant wall.
Choose one unit for the sheet, such as millimetres: 1 m equals 1000 mm. Identify the start and end points of each measurement and its height where relevant. ‘AB between the visible wall surfaces, above the skirting’ is clearer than an unlabelled number.
If readings differ between locations, record the individual values and measuring points. Do not silently average them. Measure only safely accessible areas and mark concealed points as unmeasured. This worksheet does not require opening linings or covers over connections.
Copy and complete the measurement worksheet
Copy the table into a document or reproduce it on paper. Use a separate sheet for each room. Replace the brackets with your information; omit irrelevant rows and give additional measuring points their own IDs.
Sheet heading: room [name]; planned work [task]; recorded by [name]; date [date]; condition [existing finishes or known changes]; unit [mm]. Mark each entry as measured by you, estimated, copied from a plan or still to be checked.
| ID / measuring point | What to record | Value in mm | Photo / status |
|---|---|---|---|
| AB | Wall section A–B; state measuring height and reference surfaces | [Length] | [Photo / status] |
| BC | Wall section B–C; state measuring height and reference surfaces | [Length] | [Photo / status] |
| CD | Wall section C–D; state measuring height and reference surfaces | [Length] | [Photo / status] |
| DA | Wall section D–A; state measuring height and reference surfaces | [Length] | [Photo / status] |
| H1 / H2 | Room height at the points marked on the sketch | [H1] / [H2] | [Floor reference / status] |
| AC / BD | Diagonals between the labelled corners | [AC] / [BD] | [Measuring plane / status] |
| T1 | Visible doorway: width, height and offset from a named corner | [W] / [H] / [Offset] | [Measured edges / photo] |
| F1 | Window area: width, height, position; sill height above existing floor | [W] / [H] / [Position] / [Sill] | [Measured edges / photo] |
| N1 | Recess or projection: width, depth, height and position | [W] / [D] / [H] / [Position] | [Photo / status] |
| O1 | Obstacle, such as a radiator: dimensions, projection and position | [Dimensions / position] | [Description / photo] |
Connect openings, obstacles and photos to the sketch
For T1 or F1, identify the edges you measured between: the visible opening, the existing frame or another component. These are different dimensions. Record the position along the wall, for example ‘T1 on AB, distance from A to the left visible edge of the opening’. Add a view that makes left and right unambiguous.
Mark radiators, pipes, shafts, skirting and other obstacles relevant to the job. Initially, record the position of visible connections; this does not establish their function, concealed route or suitability for connection. List known planned floor or wall changes separately.
Number photos P1, P2 and P3 and mark the camera position and direction on the sketch. Link T1 to P2, for example. An overview and a corresponding detail are easier to interpret than an unlabelled close-up. Photos do not provide a reliable scale.
Record diagonals as an additional clue
On the four-corner sketch, AC and BD are the two diagonals. Record the distances between those points in the same horizontal plane where this is safe. Describe any inaccessible corners or hidden measuring points.
Different diagonal lengths can indicate a different room shape or a measurement error. Equal diagonals alone do not prove that the corners are right angles. Keep unexpected readings with the sketch instead of adjusting them to fit an assumed rectangle.
Length multiplied by width may not describe an irregular room. Divide the sketch into clearly labelled areas without counting recesses twice. The contractor confirms the relevant geometry and accuracy needed for the work.
Keep floor area separate from the material order
Fictional calculation example: an area assumed to be rectangular is provisionally measured as 4200 mm by 3600 mm. Converting to metres gives 4.20 m × 3.60 m = 15.12 m². This calculation covers only that rectangle; it does not include additional recesses or account for different angles.
A figure of 15.12 m² is not yet a material order. Cutting, laying direction, pack sizes and the intended installation can affect the quantity required. Skirting length and the number of transitions cannot be determined from floor area alone either.
Send the measured lengths and sketch as well as the calculated area. Label an area you calculated yourself as preliminary and clarify which quantities the contractor uses in the quote.
Which dimensions the contractor needs to check
Before ordering, cutting or installation, agree who checks the critical dimensions on site and confirms the next step. For doors, the opening, wall thickness and finished floor level may matter; for furniture, assembly space and the installation position can also be relevant. Requirements depend on the product and job.
A room sketch does not establish substrate suitability, load-bearing capacity, fixing conditions or concealed service routes. Resolve these questions with an appropriate contractor. HandMen does not check measurements or technical requirements.
- Which of my figures are sufficient for an initial assessment, and which will you check yourself?
- Is a measuring visit included in your quoted scope or arranged separately?
- Must flooring, linings or other preparation be finished before the final measurements?
- Who confirms dimensions for ordering or cutting, and how are later changes recorded?
Put the worksheet and enquiry together
Before sending, check that the room, date, unit and measuring points are clear. Do photo IDs match the sketch? Are estimated and unknown figures identified? Add the intended work, location and preferred timeframe.
