Designed for children, caregivers, and visiting stakeholders, this wayfinding and signage system at the National Children’s Museum improves intuitive navigation while preserving the museum’s discovery-based experience. Playful yet clear, the signage ensures accessibility for young visitors and provides practical guidance for adults while aligning with the museum’s visual identity. Before implementing these designs, visitor feedback highlighted that the museum’s open floor plan, while architecturally inviting, often caused confusion with routes and key exhibits to be overlooked. The redesigned wayfinding system addressed these challenges through clear, consistent signage and a cohesive iconography library developed specifically for this environment. The scope of work spans a wide range of applications, including exterior awnings and windows, restrooms, floor level identification, elevators, and exhibit areas. Multiple materials, such as vinyl decals, PVC/Sintra, aluminum, and fabric, were strategically selected to suit different surfaces and contexts throughout the space. The project successfully improved navigation, reduced visitor confusion, and enhanced the overall museum experience. This work was recognized with a 2025 Graphic Design USA In-House Design Award.
