Low-fidelity wireframing is the practice of creating rough, minimalist sketches that define interface layout, information hierarchy, and navigation flow. Wireframes use basic shapes (boxes, lines), labels, and simple interactions without visual design (colors, typography, imagery). Goal is rapid iteration on structure before investing in high-detail design. Low-fidelity wireframes are a communication tool: they force clarity on "what goes where" and "how do users move through the interface." They're cheap to create and easy to change, encouraging exploration.
