There is no definitive answer to this question as it depends on a number of factors, such as the width of the walkway, the type of paving material used and the desired aesthetic. However, as a general guide, you should allow for a minimum width of 1 metre (3 feet) for a single person walking comfortably, or 1.5 metres (5 feet) for two people walking side-by-side. If you are planning to use your walkway for more formal occasions or want to create an inviting entrance to your home, then you may wish to increase these dimensions accordingly. It is also worth considering that wheelchair users will require a minimum width of 1.5 metres (5 feet).
