Surveying Door Clearance Before Specifying Entrance Mats
Door clearance and mat recess measurements should be taken together. The selected mat, its frame and the supporting build-up need to fit beneath the operating door arrangement, not just inside an empty recess.

Selection considerations
Survey the finished floor, recess base and door bottom at relevant positions. Record seals, threshold pieces and the full leaf sweep. Identify whether floor finishes or hardware are still due to change, because a survey of incomplete work may not describe the final clearance.
Compare the proposed mat and frame arrangement with the measured interface. Ask the mat and door suppliers to resolve uncertain levels or projections. A slim product label is not a guarantee that every door or sweeping seal will clear the complete assembly.
Review a sample or trial position without obstructing the entrance. Confirm the accepted drawing before custom manufacture and recheck changes before installation. Retain the survey with the product code so a future replacement can be assessed against the same opening conditions.
Before you specify or order
- Survey recess and door together
- Record sweeping seals and thresholds
- Confirm the complete assembly height
- Recheck unfinished or changed work

Common question
Does the mat thickness alone establish door clearance?
No. Frame, support, finished levels and the door's operating components must also be considered.
