Aluminum Door Measurement Checklist Before Ordering

Many door-order problems begin with an unclear dimension. “Door size” may mean masonry opening, frame outside size, leaf size or clear passage. A controlled measurement checklist helps buyers, factories and installers work from the same reference.

Record the opening, not only one width and height

Measure width and height at multiple points, then identify the controlling dimension and tolerance. Record wall thickness, reveal condition, finished floor level, sill build-up, plumb and level. For renovations, attach photographs of the opening and surrounding finishes. For new construction, include the approved section detail.

Confirm handing and configuration

State the viewing side, hinge side, swing direction, active leaf and panel movement. For sliding doors, identify which panel moves and where the lock sits. Put the same item code on drawings, packing lists and installation schedules so shipment inspection can confirm every variation.

Coordinate installation preparation

Frames need a sound opening, correct fixing zones and a drainage-compatible sill detail. Do not approve production from inspiration photographs alone. Factory testing can check operation against the approved drawing; site installation still needs level, plumb and sealant coordination.

FAQ

What is the most important measurement?

The answer depends on the specified system, but the key is to identify precisely whether every dimension refers to opening, frame, leaf or clear passage.

Should I measure after floor finishes?

Coordinate the final floor level and threshold detail before release. The installer and project professional should confirm the required reference level.

Conclusion

Clear dimensions, handing and installation details make quotations comparable and reduce rework. Treat the approved drawing as the production reference.
