How to Use This Calculator

Enter Door Width (inches) — the nominal width of the door leaf.
Set Approach: 1=Front approach, 2=Hinge-side approach, or 3=Latch-side approach based on how a wheelchair user will approach.
Set Automatic Door to 1 if the door has a power operator, which eliminates the hardware deduction.
Check Clear Opening (inches) — must be 32 inches minimum; 36 inches is strongly recommended.
Verify ADA Compliant output (1=Yes) and review Maneuvering Clearance (sq ft) to confirm floor space availability.
