What is the maximum carpet pile height permitted in accessible spaces?

• A. 1/4 inch
• B. 3/4 inch
• C. 1/2 inch or less
• D. 1 inch

Answer: (C)

Accessible spaces require a low-pile carpet to keep surfaces firm, smooth, and predictable for all users, including those in wheelchairs or using mobility aids. A maximum pile height of 1/2 inch or less ensures the carpet does not create abrupt changes in level, snag hazards, or excessive rolling resistance. When pile height exceeds that limit, the surface becomes uneven, increasing the risk of trips and making it harder for wheels to roll cleanly, which can impede maneuverability and safety. Shorter carpet heights are acceptable and common in accessible routes, which is why the maximum is stated as 1/2 inch or less. Heights taller than this, such as 3/4 inch or 1 inch, would not comply with accessibility requirements.
