How to Measure a Garage for Steel Storage Cabinets
Measure usable wall length at three heights, depth, ceiling and door clearances, then mark every obstruction and service point before choosing cabinet modules.
Record clear length, available depth and finished floor-to-ceiling height in mm. Mark doors, windows, pipes, outlets, switches, floor slope and wall construction. One tape measurement along the floor is not enough.
The six measurements to take
| Measurement | How to take it | Why it matters |
|---|---|---|
| Clear wall length | Measure at floor, worktop height and overhead height. | Bowed walls and corner obstructions can reduce the usable run. |
| Available depth | Measure from wall to the nearest obstruction or required aisle edge. | Controls base, tall, workbench and drawer depth. |
| Finished floor to ceiling | Measure in several places, including under beams and lights. | Determines whether tall units fit and how overhead cabinets are positioned. |
| Door and window clearances | Record frame width, opening swing and distance from the wall corner. | Prevents blocked access and cabinet doors hitting each other. |
| Service positions | Measure horizontal and vertical distance from two fixed corners to every outlet, switch, pipe and consumer unit. | Needed for cut-outs, cable access and maintainable clearances. |
| Floor slope and level | Use a long level or laser and record the difference over the cabinet run. | Affects plinths, adjustable feet, door alignment and levelling allowance. |
Use one coordinate system
Choose the left wall corner as zero. Mark every obstruction with X, Y and Z coordinates. This lets the cabinet drawing be reproduced without another site visit.
Take photos with a measuring reference
For each wall, include one wide photo and one close-up of every obstruction. Place a tape measure or clearly marked paper scale against the wall. Name the files by wall so they cannot be confused:
Whole run and aisle in one view
Tape measure visible
Tape measure visible
Show swing, beam and ceiling height
Measure from two fixed corners
Show slope, drain or expansion joint
Translate the wall into cabinet modules
Published reference modules are 600, 750, 900 and 1,000 mm wide. The usable run is the clear wall length minus door swing, service access and installation clearance. The final module split is confirmed when the drawing is approved.
- Reference worktop height is 900 mm, with 850 mm available on request.
- Reference overhead-cabinet underside is about 1,450 mm.
- Tall cabinets must be checked against ceiling height, beams, lights and door-opening clearance.
- Wall-mounted units require a fixing design appropriate to the actual wall substrate.
Check these points before sending the brief
- Every measurement is in the same unit.
- The tape is straight and the zero point is visible.
- Door swings and aisle widths are marked.
- No outlet, alarm, drain or pipe is hidden by the planned cabinet outline.
- The person who will install the cabinets has reviewed the fixing surface.
Buyer questions
Should I measure in millimetres or inches?
Either unit can be used, but do not mix units in one sketch. Millimetres are preferred for fabrication and module planning.
Can cabinets be made around pipes or a sloped ceiling?
Yes, but the obstacle must be measured and drawn. Depth, drawer clearances and installation sequence may need to change around it.
What wall information is needed?
Record the wall material and suspected stud or block positions. The final fixing method must be checked for the actual wall by the installer or a structural professional.
Can I send phone photos instead of a drawing?
Phone photos are useful alongside a dimensioned sketch. Photos alone do not show reliable scale, squareness or hidden obstructions.
