If base of support increases, what happens to the limits of stability?

• A. Increase
• B. Decrease
• C. Remain the Same
• D. Become Unpredictable

Answer: (A)

The limits of stability expand when the base of support increases because the region within which the center of mass can move without tipping is defined by the outer edges of the base of support. If you widen your stance or add more contact area with the ground, those boundaries move outward, giving more room to lean or sway in any direction while keeping the center of mass inside the support. In short, a larger base of support enlarges the stability area, increasing the limits of stability. Narrowing the base would shrink this area, and the other options don’t fit because stability is tied to the geometry of the base, not to unpredictability or staying exactly the same.
