Optimal Meeting Length by Type: Brainstorm Decision and Status

Most meetings are 30 or 60 minutes because that's what the calendar offers by default, not because the work needs it. Matching length to the type of meeting is one of the easiest ways to give people time back.

Suggested lengths by type

• Status update: 0 to 15 minutes. Most can be written instead. If it must be live, keep it short and to exceptions.
• Decision meeting: 25 to 45 minutes. Send options in advance so the time goes to deciding, not explaining.
• Brainstorm: 45 to 60 minutes. Ideas need warm-up time, but energy drops after an hour. Break longer sessions into rounds.
• One-on-one: 25 to 30 minutes weekly, or longer every other week.
• Planning or workshop: 90 minutes or more, with breaks, for work that genuinely needs a group.
• Quick decision or unblock: 10 to 15 minutes, with only the people who decide.

Rules that keep meetings short

1. Write an agenda with a goal. "Decide X" is a goal; "discuss X" isn't. The meeting agenda builder helps.
2. Default to shorter slots. Many calendars can end meetings early automatically; see the case for 25-minute meetings.
3. Send reading in advance and don't present it in the meeting.
4. End when the goal is met, even if time is left.
5. Invite only people who contribute or decide.

Check what your meetings cost

Length times attendees is the real cost. A 60-minute brainstorm with eight people is a full working day. The Meeting Cost Calculator makes that visible, which helps teams agree on shorter defaults.
