An accessible toekick must have a minimum height of ____ and a maximum depth of ____.

The correct specifications for an accessible toekick, which is a component in design requiring compliance with accessibility standards, establish that it must have a minimum height of 9 inches and a maximum depth of 6 inches. This standard is significant because it ensures enough space under counters for individuals using wheelchairs or other mobility aids, allowing them to approach and use surfaces comfortably.

The height allows individuals to position their legs underneath while the maximum depth is crucial to ensure proximity to the surface (like counters or cabinets), optimizing accessibility without compromising functionality or aesthetic design. Following these measurements helps designers create inclusive spaces that accommodate a wider range of users, aligning with universal design principles.

The other options do not meet the established accessibility standards for toekick dimensions and would not adequately serve the intended purpose of accommodating users with mobility limitations.
