How to use it
A clear, quick workflow
- Choose a preset or apply a custom duration.
- Start, pause, resume, and reset with the controls or documented keyboard shortcuts.
- Open fullscreen for a projector; enable sound only if you want an end alert.
Fullscreen Classroom & Presentation Timer
Show a large, projector-friendly timer for lessons and talks.
00:05:00
Presentation timer ready.
Shortcuts: Space/Enter starts or pauses, R resets, and F opens fullscreen.
Example
Use the 10-minute preset for a talk and watch for written one-minute and ten-second warnings.
Limits and behavior
Timing uses the browser monotonic clock and recalculates after delayed updates. Fullscreen and audio depend on browser permission and user gestures; written warnings always remain available.
FAQ
Does this replace the regular Timer & Stopwatch?
No. This separate tool prioritizes a large projector display, fullscreen controls, keyboard shortcuts, and visible end warnings.
Practical guidance
Choose and use this tool with confidence
When a presentation timer helps
Use the large display when the remaining time needs to be readable across a room, such as for student talks, workshop exercises, debate rounds, meeting breaks, or speaker practice.
- Choose one duration before the session and reset it between speakers for consistent turns.
- Use fullscreen on the projected display and keep written warnings visible when sound would interrupt the room.
Presentation timer or regular timer?
Choose this tool for a projector-friendly countdown, visible warning states, fullscreen controls, and keyboard operation. Choose the regular Timer & Stopwatch when you also need elapsed-time measurement or a compact personal timer.
