A DIY playroom to test your designs.
GDC evaluates designs against a much broader set of dimensions, curated by our Global Design Councils. This calculator gives you a glimpse into how design can be measured.
Because not all dimensions are equal. Their weights change by product and context — safety may outweigh appeal in an appliance, while experience may matter more in a lifestyle product.
Play with the dimensions. Score your design.
Grip, reach, posture, force, hand/body interaction; impacts physical comfort and safety
Task completion, cognitive load, instruction dependency; impacts adoption and satisfaction
Usability across age, ability, vision, dexterity and physical limitations
Brand coherence, category cues, proportions and visual hierarchy; impacts appeal and recall
Tactility, perceived quality, durability, heat/chemical resistance
Parting lines, fastening, component integration and service access; impacts perceived quality and manufacturing
Gaps, alignment, joints and component fit; impacts quality perception and reliability
BIS, CE, UL, RoHS and applicable safety/marking requirements
Thermal, electrical, pressure, mechanical and misuse protection
How clearly the product communicates operating state, performance and completion
Recycled content, material efficiency, mono-material potential
Access to components, spares, tools, modularity and disassembly
Packaging, reveal, protection, setup and packaging waste
Time and effort to achieve first successful use
Cleaning, consumables, descaling, filters, service prompts
Disassembly, recyclability, material separation and disposal
