Final answer:
The standard, recommended width for an outdoor walkway is typically around 1.2 meters (4 feet) for a single person to comfortably walk.
Step-by-step explanation:
The standard, recommended width for an outdoor walkway can vary depending on factors such as location, foot traffic, and accessibility requirements. However, a general guideline is to have a minimum width of 1.2 meters (4 feet) for a single person to comfortably walk. This allows enough space for people to pass each other comfortably. In some cases, wider walkways of around 1.8 meters (6 feet) may be recommended to accommodate strollers, wheelchairs, or large groups of people.
