This debate timer shows how long a Public Forum debate round, a Lincoln-Douglas round or a Policy round takes, then runs every speech on a big color panel with a separate prep clock for each side.
Runs entirely in your browser — nothing is uploaded. Panel turns yellow with 30 seconds left and red at time. Keep this tab in front while timing. If you leave prep blank, the timer uses the format’s usual prep: 3 min (Public Forum), 4 (Lincoln-Douglas), 8 (Policy) or 2 (Custom).
How Long Is a Public Forum Debate Round?
A Public Forum round runs about 41 minutes on the common format: 35 minutes of speeches and crossfires plus 3 minutes of prep for each team. Lincoln-Douglas comes to 40 minutes and Policy to 80 minutes, before any breaks or the judge’s decision.
| Format | Speeches | Speech lengths (min) | Speaking time | Prep per side | Round length |
|---|---|---|---|---|---|
| Public Forum | 11 | 4, 4, 3, 4, 4, 3, 3, 3, 3, 2, 2 | 35:00 | 3:00 | 41:00 |
| Lincoln-Douglas | 7 | 6, 3, 7, 3, 4, 6, 3 | 32:00 | 4:00 | 40:00 |
| Policy (CX) | 12 | 8, 3, 8, 3, 8, 3, 8, 3, 5, 5, 5, 5 | 64:00 | 8:00 | 80:00 |
| Custom class debate | 6 | 5 each | 30:00 | 2:00 | 34:00 |
- Add the Public Forum speech lengths: 4 + 4 + 3 + 4 + 4 + 3 + 3 + 3 + 3 + 2 + 2 = 35 minutes.
- Double the prep per side: 2 × 3 = 6 minutes.
- Add them: 35 + 6 = 41 minutes.
How the Timer Works
Pick a speech and the clock counts down from its full length. With 30 seconds left the panel turns yellow, at zero it turns red, and if the speaker keeps going it counts the overtime with a plus sign. Prep clocks are separate: starting one pauses the speech clock, and each side’s prep carries over from speech to speech until it is used up.
Formula: time shown = speech length − elapsed time, rounded up to the second; overtime = elapsed − speech length. Speaking time = sum of all speech lengths. Round length = speaking time + 2 × prep time per side. Panel color: green while more than 30 seconds remain, yellow from 30 seconds to zero, red at zero and beyond.
- Format: Public Forum, Lincoln-Douglas, Policy (CX) or Custom; each loads its speeches and its usual prep time.
- Prep time per side: minutes each team may use across the round; if you leave it blank, the timer uses the format’s usual prep time.
- Number of speeches, Minutes per speech: shown only for Custom.
- Speech: the current speech; Next speech moves down the list.
- Run prep: starts or pauses that side’s prep clock.
Public Forum Debate Prep Time and Other Tips
Public Forum debate prep time is 3 minutes per team in the preset, but leagues and tournaments set their own times. The presets follow widely used US high school schedules, so check the invitation or ballot before round one.
- Use the prep clock for each side and announce the remaining prep aloud when a team stops it.
- Lincoln-Douglas debate speech times include two 3-minute cross-examinations, which belong to the opponent who asks, not the speaker.
- Policy debate speech times add up to 64 minutes, or 80 with prep, so plug in the laptop and turn off sleep.
- Grace periods for finishing a sentence vary; agree on them before the round.

Common questions about debate timing
How long is a Public Forum debate round?
With the common format, about 41 minutes: 35 minutes of speeches and crossfires plus 3 minutes of prep for each team. Breaks between speeches and judge decisions add to that, and your league may use different times.How much prep time does each side get?

College and international leagues often allow more. Type your own number and both clocks reset to it.What are the Lincoln-Douglas debate speech times?
The preset uses a 6-minute affirmative constructive, 3-minute cross-examination, 7-minute negative constructive, 3-minute cross-examination, 4-minute first affirmative rebuttal, 6-minute negative rebuttal and 3-minute second affirmative rebuttal. That is 32 minutes of speaking plus 4 minutes of prep per side.Can I use the debate timer online for a virtual tournament?
Yes. Share your screen or just the browser window in Zoom, Teams or Meet, then press Full screen on the color panel so debaters see the countdown fill their view. Read out the remaining prep time when a team stops its prep clock so both sides hear it.What happens when a speaker goes over time?
The panel turns red at zero and the clock keeps counting with a plus sign, such as +0:12, so the judge knows exactly how far over the speech ran. Most judges let a speaker finish the sentence, but the rule belongs to each tournament.Can the timer handle a class debate?
