Prototyping your layout designs can be done in different stages, depending on your design goals, budget, and timeline. The level of fidelity, or how realistic and detailed your prototypes are, can vary to test the designs in different stages. Sketching is the lowest level of fidelity where you draw quick and rough sketches of the layout designs with paper and pencil. This is a great way to brainstorm ideas and generate multiple design concepts. Wireframing is a low to medium level of fidelity where digital tools are used to create basic and schematic representations of the layout designs. This is useful for defining, organizing, and structuring elements like content, navigation, and functionality. Mockup is a medium to high level of fidelity where digital tools are used to create realistic and detailed representations of the layout designs. This is the stage for refining, polishing, and styling elements such as colors, fonts, images, and icons. Prototype is the highest level of fidelity where digital tools are used to create interactive and functional simulations of the layout designs. This stage is ideal for testing, evaluating, and demonstrating interactions, animations, transitions, and feedback.
