The timeline for a UI/UX design project depends on the size, complexity, and requirements of the project. A simple website or application may take a few weeks, while larger platforms with multiple features, user research, wireframes, prototypes, and usability testing can take several months. Factors such as client feedback, design revisions, and the number of screens also influence the overall duration. A structured design process ensures the final product delivers an intuitive, engaging, and user-friendly experience.
