A ladder with nesting braces device is disclosed which significantly improves the bilateral stability of the ladder minimizing risk of injury to an individual while simultaneously retaining a standard ladder design profile. The nesting braces internally receive the pair of side support rails during storage of the ladder. Each of the nesting braces includes a hinge engagement section having at least one locking mechanism. Each of the side support rails includes a hinge and a pair of gusset plates having a locking mechanism adapted for engagement to the hinge plates. The hinge and a corresponding hinge engagement section provides for the structural support and pivotal rotation of a nesting brace with respect to a side support rail. Each of the nesting braces may additionally include an expansible-leg having a releasable carriage/housing for vertical adjustment to securingly engage a surface during use of the ladder upon a non-level surface.
