Width : give it greater importance, for it determines the largest number of participants possible : 1.20 m (4') wide = one route for a pair climber/belayer

Configuration : plan some inclines or overhangs : maximum 2 m (7') slab for beginners not necessary, rather plan a vertical surface

Average height : 5 m to 9 m (16' to 30')

Number of protruding holds : 5 to 8 / sq. m (5 to 8 / 10 sq. ft)

Support : whether the available support is a concrete wall, a breeze block wall, a steel frame, timber columns or other, there is always a possibility to adapt a corresponding climbing wall support. The option of self-standing climbing wall supports is also a solution

Crash area : indoors = fold-away crash mats / outdoors = gravel base 30 cm (1') deep

Clearance zone : 3 m (10') in front of the largest overhang

Safety : plan belay anchor systems on the floor, 2.50 m (8') in front of the wall (anchoring case with removable cap) to allow a sure belaying for beginners, draw a red line at a 3 m (10') height to indicate the limit of climbing without rope belaying (traversing).
