Which navigation pattern is typically best for mobile interfaces with limited space?

• A. Top navigation with global actions.
• B. Side navigation for primary content.
• C. Bottom navigation that targets core actions.
• D. A combination of top, side, and bottom on every page.

Answer: (C)

When space is tight on mobile, keep the most-used destinations always within easy reach and visible. Bottom navigation places a small set of core actions along the bottom edge, where the thumb naturally rests, making it quick to switch between main sections without taking you away from the content. This layout stays in view as you scroll and doesn’t obstruct the screen with menus or drawers, which is why it’s the best fit for limited-screen interfaces. Top navigation can crowd the header, and side navigation hides options behind a panel that requires extra taps to access, slowing you down. Mixing multiple navigation patterns on every page adds clutter and cognitive load.
