To achieve a wider stair at the bottom than at the top, modifying the stair's run by converting it to a sketch allows for a custom shape. This sketching method enables users to directly manipulate the boundary and riser lines of the stair component, effectively creating a variable width that tapers as you move up. By adjusting the sketch, the designer can ensure that the lower part of the stair is broader, while the upper part remains narrower, achieving the desired geometry.

Other options do not address the requirement for changing the shape of the stair. Changing the material only affects the aesthetic and physical properties of the stair, such as its appearance and structural characteristics, but does not influence the geometry. Altering the stair type to a straight stair does not inherently provide the variable width needed. Lastly, adjusting height parameters manages vertical dimensions but does not impact the horizontal layout or width of the stair runs themselves.
