What is the typical angle of inclination for a commercial escalator as per general safety standards?
Answer & step-by-step solution
A common commercial escalator inclination is about 30° to the horizontal. This provides a practical compromise between vertical rise, passenger comfort, safety and floor-space requirements.
Concept & Reasoning
Escalator geometry is standardized around safe tread orientation and passenger stability. Steeper arrangements can reduce plan length but are less comfortable and may fall outside common public-use design practice. The 30° value is the standard exam answer among the choices.
How to Solve It in the Exam

Important Exam Point
Do not confuse escalator slope with stair or moving-walkway limits.
Quick Trick
Escalator → remember 30°.
Common Mistake
Choosing 45° because ordinary stairs can visually appear that steep.
