3daysofdesign is a Copenhagen design festival held every June since it launched in 2013 in the city’s Nordhavn harbor district. It has since grown into a city-wide event spread across showrooms, galleries and public spaces in neighborhoods throughout Copenhagen, combining brand showroom openings with exhibitions and installations rather than a single trade-fair hall.

The festival centers on furniture, lighting and interior design, with participating brands presenting new collections and collaborations inside their own showrooms. Recent editions have drawn several hundred exhibiting brands and around 100,000 visitors, including designers, retailers, press and the public, alongside talks, conferences and networking events. Known for its relatively low-key, design-led format compared with larger trade fairs, it has become one of Scandinavia’s key stops on the international design calendar.
