Flowtrace’s 2025 analysis of 1.3 million real meetings found the median meeting duration is 35 minutes — significantly shorter than the 60-minute calendar default. HubSpot research found that shortening virtual meetings to under 30 minutes improves productivity by 20%. The evidence supports matching duration to content rather than to calendar slots: estimate the genuine time requirement of the meeting content, subtract 5–10 minutes, and set that as the scheduled duration.
