Duration, buffers, and limits
Every event type has a set of timing controls that shape what slots appear on its booking page. The defaults are sensible — most people only change one or two. You find them in the event-type editor (open it from Event Types): Duration is on the General tab; the rest are on the Limits & Buffers tab — see the editor overview.
The controls
| Setting | What it does | Default | Range / options |
|---|---|---|---|
| Duration | How long the meeting is. | 42 min | 10–120 min |
| Buffer before | Padding kept free before the meeting (travel, prep). | 15 min | 0 / 5 / 10 / 15 / 30 / 45 / 60 min |
| Buffer after | Padding kept free after the meeting. | 15 min | 0 / 5 / 10 / 15 / 30 / 45 / 60 min |
| Minimum notice | How far ahead someone must book — no last-minute slots. | 4 hours | 0 min – 7 days |
| Date range | How far into the future bookings are allowed. | 15 days | 1–365 days |
| Start time increment | The spacing of offered start times (e.g. every 30 min on the hour/half-hour). | 42 min | 1–120 min |
| Meeting limits | Optional caps — max meetings per day / week / month for this event type. | none | your choice |
42min computes the booking page like this: start from the event type's schedule → remove your calendar's busy events → remove the before/after buffers around existing meetings → drop anything inside the minimum-notice window or beyond the date range → offer start times on the increment → respect any meeting limits.
When to change them
- Back-to-back meetings wearing you out → raise the buffers (or the increment).
- People booking you for 20 minutes from now → raise the minimum notice.
- You only want to be booked for the next two weeks → shorten the date range; for interviews scheduled a month out, lengthen it.
- Cap how much of your week one event type can eat → set a weekly meeting limit.
- Cleaner-looking slot grid → set the start time increment to 15 or 30 minutes.
Note
Buffers and meeting limits are per event type. If you have several event types sharing the same schedule, a big buffer on one of them doesn't pad the others — set each one's timing for the kind of meeting it is.
Common pitfalls
- Slots disappeared after raising buffers. Large before/after buffers on a busy calendar can swallow most of a day. Step them down (try 10 or 15 min) and check the booking page again.
- "No times available" near-term. That's usually the minimum-notice window doing its job — or a date range that's too short. Both live on the Limits & Buffers tab of the event type.
- Odd start times. A 42-minute increment produces start times like 9:00, 9:42, 10:24… If you want them on the hour/half-hour, set the increment to 30.
