What are the minimum dimensions required to complete a wheelchair U-turn?

• A. 54 inches wide by 72 inches long
• B. 66 inches wide by 84 inches long
• C. 72 inches wide by 90 inches long
• D. 60 inches wide by 78 inches long

Answer: (D)

To turn a wheelchair around in a confined space, you need a clear turning area about 60 inches in diameter. That means the space must be at least 60 inches wide to accommodate the turning circle. But you also need enough length to enter, pivot, and exit the turn smoothly, not just fit the circle. The smallest rectangle that fits a 60-inch turning circle and still allows a complete U-turn is 60 inches wide by 78 inches long. A shorter length would prevent finishing the turn, even if the width fits the circle. Among the options, this pairing provides the minimum width to fit the turn and the shortest length that still works, defining the minimum dimensions. Therefore, the minimum is 60 inches wide by 78 inches long.
