What should I measure before choosing a door?

Can I start without a complete drawing?

Yes. Begin with the clear opening width and height, available space around the opening and photographs of both sides. Label all dimensions and units; uncertain measurements should be identified for checking.

Capture the opening and obstructions

Record width, height, headroom, side room on both sides and available backroom. Show the finished floor level, wall construction, columns, beams and nearby services. A photograph without dimensions is useful context but is not an installation drawing.

Describe the operating conditions

Add indoor or outdoor location, traffic, exposure, temperature on each side and power supply. For replacement work, include the existing door and operator labels, track arrangement and the problem you want to solve.

Confirm before fabrication

Use the project drawing review to agree final dimensions, fixing interfaces and the scope of site work. Preliminary measurements support selection; they do not replace confirmation of the final opening and installation interfaces.

Selection guidance based on the JBL Entrance door systems catalogue and project enquiry checklist. Final suitability, dimensions and configuration require project-specific confirmation.
