How to Measure for a Glass Partition
Accurate measurement is critical when ordering a glass partition. Anyone who has fitted internal doors, hung kitchen units, or done similar work will find this straightforward. Follow the steps below to get the measurements we need.
1. Measure the width of the opening
Measure the width of the opening at three different heights — top, middle, and bottom — using a laser measure or a steel tape. If the three measurements differ, submit the smallest. This ensures the glass will fit into the tightest point of the opening. You will need to ensure that channels are fixed at this height/width
Measure wall to wall, not skirting to skirting. The wall channels need to sit flush against the wall surface, so where skirting boards are in the way, they need to be cut into. A skirting-to-skirting measurement will produce panels that don't fit. If there is trunking rather than skirting, you will need to infill around this with timber. In the case the width provided should be from timber to timber.
All measurements should be provided in millimetres.
2. Measure the height of the opening
Measure the height from floor to ceiling at three points — left, middle, and right. As with the width, submit the smallest of the three.
If the partition includes a door, the height at the exact point where the door pivot will sit is the most important measurement. Door heights have very little tolerance.
3. Note any skirting, trunking, or ceiling obstructions
Skirting boards need to be cut into so the channels can mount flush, or packed out with timber to the face of the skirting and measured to that.
For trunking running across the opening at any height, the same timber-packing method works: run timber down the wall flush with the trunking and take the measurement from timber to timber.
For ceiling-level obstructions (lights, air ducts, ceiling roses near where a door will swing), mention them on the order. A transom door with an overhead panel above the door leaf can often allow the door to swing beneath an obstruction.
4. Allow for floor finishes and door clearance
Glass partitions should be fitted onto the finished floor, including any carpet. If the floor finish isn't down yet, this needs noting on the order so that we can alter tolerances.
Frameless doors have 13mm clearance underneath, which allows for up to 10mm of carpet to be fitted around the door afterwards.
Framed doors have 5mm clearance. If flooring is being laid after the partition is installed please contact us before ordering to discuss. It is strongly recommended that the partition is fitted after the floor and that sizes provided are from finished floor to finished ceiling.
5. Submit the tight sizes — we handle the rest
Submit the exact opening dimensions as measured. Don't deduct anything for channels, gaskets, doors, or fitting tolerances. We allow for all of that in the manufacturing — generally 15mm next to the walls, 5mm either side of a frameless door, 4mm for dry joins between panels, plus the relevant allowances for hinges and door frames where applicable.
6. Final check
Before placing the order: dimensions in millimetres, smallest measurement at each point, nothing deducted, door pivot height noted precisely if the ceiling is uneven, floor finish situation noted if relevant.
Once the measurements are confirmed, use our glass partition calculator to price your kit and order online. Delivery in 7 working days.
If you have your own glass supplier and only need the hardware, we sell complete kits without glass with next-working-day delivery on orders placed before 12pm.
Uneven walls, floors, or sloping ceilings
For variation under about 10mm, packed out behind the channels during installation. Submit the smallest measurement.
For larger variation, send a sketch of the opening with measurements at top, middle, and bottom of the width, and left, middle, and right of the height. Email it to us and we'll come back with the right configuration within one working day.
For significantly sloping floors, a larger U-channel (50mm rather than the standard 30mm) absorbs the slope. The glass is packed inside the channel during installation to sit level. Call before ordering and we'll specify the right channel size.
For significantly sloping ceilings, either fit the ceiling channel level at the smallest measured height and accept a small gap above the channel where the ceiling rises, or we manufacture different panel heights across the width to follow the ceiling line. The door height matters most either way.
