Will an item fit through the measured narrowest opening?

A four-step working method

1. Measure the narrowest usable opening with handles and door position included.
2. Record the item’s actual transport orientation and package dimensions.
3. Check turns, slopes and floor conditions independently; width alone does not prove access.
4. Confirm handling method with the supplier and appropriate professional.

Common errors to avoid

• Approving a route from door width without checking turns, handles and thresholds.
• Treating an empty worksheet field as a confirmed zero or a verified fact. Mark missing information explicitly.
• Sharing a working brief as a professional conclusion. Keep assumptions and unanswered questions attached.
