Offer several meeting lengths within a single event type and let bookers pick the one they need. In Cal ID, you don’t have to create multiple separate events just to offer different durations—Multiple Durations lets your guests decide how much time they need before choosing a time slot.

Offering multiple durations

This feature allows a single event type to have multiple time options (for example: 15, 20, and 60 minutes). The guest picks the length that suits them best before choosing a time slot.

Why use multiple durations?

  • Cleaner Profile: Keep your booking page simple by grouping different time options under one event.
  • Guest Flexibility: It gives the booker the power to choose exactly how much of your time they need.

How it looks for the booker

When a guest visits your booking link, they will see your list of available durations. Once they select a duration, the calendar will automatically update to show only the time slots that can fit that specific meeting length.

Important things to know

  • Smart Availability: If a guest picks a 60-minute meeting, Cal ID will automatically hide any smaller gaps in your schedule that aren’t long enough for a full hour.
  • Easy Management: You can quickly add or remove duration options at any time by clicking the “x” next to a time in the Available durations list.
Set your Default duration to the length most guests will want. It’s pre-selected on the booking page, so a well-chosen default means fewer clicks for the common case.
