Direct answer: Single swing doors work well when one leaf can provide the required clear passage without conflicting with furniture, worktops or escape routes. The key decisions are hinge side, swing direction, latch position, threshold and the space the leaf occupies when open.
Start with a floor plan that shows the door closed, at 90 degrees and at its intended maximum travel. This reveals conflicts that a front elevation hides, including handles hitting walls and the leaf blocking a corridor.
Choose handing from the plan
Mark the hinge jamb, active face and latch side from the approach used most often. Confirm whether the door should swing into the room or toward the corridor, then check circulation and any accessibility requirement that applies to the project.
Measure the full swing
Record the leaf width, frame projection, handle arc and the distance to adjacent walls. Keep radiators, cabinets and switches outside the sweep. If a closer or hold-open device is required, include its projection in the drawing.
Coordinate the threshold
Note the finished floor on both sides and specify how the threshold meets flooring. Exterior openings also need a documented sill, seal and drainage detail. Do not assume a low threshold is suitable until the water-management and access requirements are reviewed together.
Quotation checklist
| Item | Evidence |
|---|---|
| Handing | Hinge and latch sides labelled on plan |
| Travel | 90-degree and full-open clearances |
| Hardware | Closer, lock, handle and service access |
| Handover | Adjustment, cleaning and warranty scope |
Coordinate installation and handover
Write down who prepares the substrate, sets the frame, seals the perimeter and adjusts the hardware. Keep the approved plan on site so substitutions are visible. At handover, cycle every leaf, test the lock and record the cleaning and adjustment method. The owner should know which tasks are routine and which require the installer.

Frequently asked questions
How much room does a swing door need?
Use the leaf width plus frame, handle and hardware projections, then test the complete sweep against furniture and routes.
Should it swing in or out?
Compare circulation, privacy, weather and any code or egress direction that applies to the project; approve the decision on the plan.
Can a single door be made accessible?
Potentially, but clear width, threshold and opening force must be checked against the applicable accessibility requirements.
