Pecha Kucha is twenty slides shown for exactly twenty seconds each, advancing automatically for a talk of six minutes and forty seconds. This timer keeps that beat: a beep every twenty seconds and the slide number ticking from 1 to 20, so you talk to the slide in front of you and let the clock carry you forward.
The format’s whole discipline is that you cannot linger — the slide changes whether you are ready or not, which forces a tight, well-rehearsed talk. Set your deck to auto-advance at twenty seconds to match, and use this as the master clock and your rehearsal tool. To run a non-standard length, open it in the editor and change the slide count or seconds.
A flat five minutes — twenty slides, fifteen seconds apiece, five seconds tighter than Pecha Kucha and far less forgiving. The beep is your cue to click on; set your slides to advance to match it.
Five minutes to land one clear idea, counted down to a single beep so a packed bill of speakers stays on schedule. Running a three-minute slot instead? Change the length in the editor.
Sixty seconds to say who you are and why it matters before the doors open. Drill it until the ending lands without a rush; trim it to 30 seconds in the editor for the sharper cut.
Eighteen minutes — the TED ceiling, the point past which a talk loses the room. It is a limit, not a target, so rehearse until yours finishes comfortably under. Reset the length in the editor for any other cap.
