Presentation timer
A free presentation timer that opens on ten minutes and keeps the countdown in your tab title while your slides are up. On a laptop beside the lectern it works as a confidence monitor without any extra hardware. Also searched as talk timer, speaker timer, presentation countdown.
Common talk formats
| Format | Length | Notes |
|---|---|---|
| Lightning talk | 5 min | One idea, no agenda slide |
| Ignite | 5 min | 20 slides, 15 s each, auto-advance |
| Pecha Kucha | 6 min 40 s | 20 slides, 20 s each |
| TED-style | up to 18 min | Most run 12 to 18 |
| Conference talk | 20–30 min | Leave 5 for questions |
| Keynote | 45–60 min | Plan a change of pace every 10 min |
For Ignite and Pecha Kucha, set 15 or 20 seconds and tick Repeat. Each alarm is your cue that the slide has moved, which keeps rehearsal honest.
A rehearsal method that works
- Run the talk out loud three times, never in your head. Press Space before the first word.
- Aim to finish at about 90 percent of the slot. A ten-minute slot means a nine-minute talk, because live delivery always runs long.
- Record the time at each section with the stopwatch and laps. A section that drifts between runs is the one to cut.
- On the last run, rehearse the ending twice. Audiences remember the close.
On the day
- Open this page on a device you can glance at, press F, and choose Silent so no alarm plays through the room speakers.
- Turn on dark mode with the moon button if the room is dim.
- Check the ring, not the digits. A quarter ring left means a quarter of the talk left.
Shorter slots fit the 10 minute timer and the speech timer, which covers Toastmasters and debate limits. Longer sessions start from the 20 minute timer.
Frequently asked questions
How long should a 10-minute presentation actually run?
Rehearse to about nine minutes. Live talks run longer because of pauses, questions and slide changes.
Can I see the timer while presenting fullscreen slides?
Open aTimer on a second device or a second display. The remaining time also shows in the browser tab title whenever the tab is visible.
How do I rehearse an Ignite talk?
Set 15 seconds, tick Repeat and press Space. Every alarm is a slide change, exactly like the auto-advance on the day.
