Keep a talk to time on a big, easy-to-read display. Auto-advancing slide formats like Pecha Kucha and Ignite, plus capped countdowns for a lightning talk, an elevator pitch, or an 18-minute TED-style talk — a single beep marks every slide change and the finish.
Twenty slides, twenty seconds each — 6:40 of talking to whatever is on screen, with a beep at every change. Set your deck to auto-advance at 20 seconds and let the timer keep you honest.
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.
A talk that runs long loses the room, and one rehearsed against a stopwatch you have to keep glancing at never flows. A presentation timer takes the clock-watching off you: set the format once, press start, and a single beep tells you when to move on or wrap up, so your attention stays on the audience and not the time remaining.
Every format here runs entirely in your browser, with nothing to install and no account, on a display you can read from the back of a room or from a lectern. The cue is one short beep — no spoken count, nothing that talks over you — so it marks the moment cleanly and gets out of the way.
Some presentation formats are a fixed run of equal slides that advance on their own: Pecha Kucha is twenty slides of twenty seconds, Ignite is twenty of fifteen. For these the timer beeps and the slide number ticks over — Slide 1, Slide 2, on to 20 — so you can pace each slide and never fall behind the deck. The discipline is the point: you talk to the slide in front of you and let the clock advance it.
Other formats are a single capped countdown — five minutes for a lightning talk, sixty seconds for an elevator pitch, eighteen minutes for a TED-style talk — where you control the slides yourself and only need to know you are inside the limit. Those count down to one finishing beep. Either way the format is in the page address, so a timer you rehearse with often is a bookmark away.
Most people meet these timers in rehearsal, running a talk again and again until it lands inside its limit. The countdown formats repeat for exactly that: open one in the editor, raise the rounds, and it runs back to back so you can take another pass without resetting. The slide formats hold their structure every time, so a Pecha Kucha you have drilled at twenty seconds a slide behaves identically on the night.
None of the five formats fits your slot? Open any of them in the editor and change the slide length, the number of slides, or the countdown to match the brief you have been given. The same timers are in the free Seconds Interval Timer app on iOS and Android, so a talk you build on the web is on your phone at the lectern.
