How to Set Default Meeting Length in Google Calendar (Speedy Meetings, Custom — 2026)
Google Calendar’s default event duration is account-wide. Change it once and every new event you create starts with that length pre-filled. Pair with Speedy meetings — Google’s built-in trick that ends meetings 5–10 minutes early — to claw back time between back-to-backs.
1. Change the Default Duration on Web
- Open Google Calendar.
- Click the gear icon → Settings.
- Left sidebar → General section → click Event settings (the first item under General).
- Click the Default duration dropdown.
- Choose 15, 20, 25, 30, 45, 50, 60, 90, or 120 minutes — or click Custom to type any value in minutes.
- Settings save automatically — there’s no Save button on this screen.
Every new event you create starts at this duration. Existing events are unaffected.
2. Enable Speedy Meetings
Speedy meetings ends meetings before the top of the hour or half-hour, giving you a buffer between back-to-backs.
- On the same Event settings screen, find Speedy meetings.
- Tick the checkbox: End 30-minute meetings 5 minutes early and longer meetings 10 minutes early.
What it does:
| Default | Effective duration with Speedy meetings |
|---|---|
| 30 min | 25 min |
| 45 min | 40 min |
| 60 min | 50 min |
| 90 min | 80 min |
| 15 min | Unchanged |
It only affects newly created events using the default. It does NOT retroactively trim existing events. It does NOT apply when you manually drag an event to a custom duration.
3. Change the Default on iOS
- Open the Google Calendar app.
- Hamburger menu (☰, top-left) → Settings.
- Tap General.
- Tap Default event duration.
- Choose 15 / 30 / 45 / 60 minutes, or Custom.
- Below that, toggle Speedy meetings.
These mobile settings sync with web — they’re the same account-level preference, despite the slightly different label (“Default event duration” mobile vs “Default duration” web).
4. Change the Default on Android
- Open the Google Calendar app.
- Hamburger menu → Settings.
- Tap General.
- Tap Default event duration.
- Pick a duration.
- Toggle Speedy meetings.
Identical behavior to iOS.
5. Per-Calendar Defaults? No.
There’s no per-calendar default duration. The setting is account-wide. If you want different defaults for different contexts:
- Use a custom duration when creating each event manually.
- Use Appointment Schedules for booked sessions — those have their own duration setting (section 8).
6. Related Settings on the Same Screen
The Event settings panel also includes:
- Default guest permissions: Modify event, Invite others, See guest list — checkboxes that pre-fill on every new event.
- Default notifications: applies to events on your primary calendar only. See how to set reminders in Google Calendar.
- Add video meetings to events I create: auto-attaches Google Meet to events with guests. See how to create a Google Meet link.
- View options: Reduce the brightness of past events, weekend toggle, declined event display.
7. Why Speedy Meetings Matters
The unspoken cost of meetings is the no-man’s-land between them. A 9–10 AM meeting that genuinely ends at 10:00 leaves zero time to walk to the next room, get water, or transition mentally. Most people end up running 5 minutes late to the 10:00.
Speedy meetings makes the buffer a default rather than something you remember to negotiate.
It works best when most attendees in your org also use it — otherwise you’re ending early but the other person scheduled a hard 10:00 follow-up.
8. Appointment Schedules: Separate World
Default duration does NOT control Appointment Schedule slot length. Each schedule has its own duration field.
To change an Appointment Schedule duration:
- Open the schedule (Calendar → click the schedule in the grid → Open booking page → Manage, or directly under Settings).
- Appointment duration field on the booking page editor.
- Defaults to 30 min, supports 15 / 20 / 30 / 45 / 60 / 90 / 120 or custom.
- Save.
Speedy meetings also does NOT shorten Appointment Schedule slots — that toggle only affects normal events.
9. Workspace Admin Defaults
Admins can set an org-wide default duration:
- Admin Console → Apps → Google Workspace → Calendar → Sharing settings → Default event duration.
User settings override the org default unless the admin locks the setting (using the lock icon in Admin Console).
Speedy meetings has no admin-side equivalent — it’s per-user only.
10. Custom Duration Use Cases
The custom duration field accepts any minute value. Common picks:
| Custom value | Use case |
|---|---|
| 5 min | Quick syncs, status checks |
| 10 min | Brief decisions, approvals |
| 25 min | Speedy 30-min equivalent without enabling Speedy meetings |
| 50 min | Speedy 60-min equivalent |
| 75 min | Long working sessions |
| 180 min | Half-day workshops |
You can type values up to 1440 (24 hours).
11. The 25-Minute Default Pattern
Some teams skip Speedy meetings entirely and just set the default to 25 minutes. The advantage: every meeting is intentional in length, and there’s no “but I’m running long” Speedy meetings reset.
Disadvantage: harder to schedule when others use 30. You spend more time picking custom durations to sync up.
12. Common Gotchas
- Existing events don’t shorten when you change the default. Speedy meetings doesn’t retroactively trim.
- Drag-creating an event ignores the default duration — the event is whatever length you dragged.
- Quick-create from the grid popover uses the default duration. The full editor uses whatever you set when you click “More options.”
- Workspace admin override: if your admin locked the default, you can’t change yours. The Default duration dropdown is greyed out.
- Speedy meetings 5/10-minute split is not configurable. You can’t make it 15 minutes or 7 minutes.
