About the Boxing Timer
This is a round timer for boxing, ready to go: 3-minute rounds, 1-minute rest and 12 rounds, like a pro fight. Press Start and it runs the whole session for you. A bell rings when a round starts, three bells ring when it ends, and a wooden clapper warns you 10 seconds before the end, like in a real gym.
The countdown is big enough to read from the heavy bag, and Fullscreen fills a laptop, tablet or TV with it. One tap switches to other common setups — amateur, MMA, Muay Thai or bag work — or type your own round and rest times.
Features
- Boxing setup ready — 3-minute rounds, 1-minute rest, 12 rounds, 10 seconds to get ready

Round setups and their total time
The total time is the rounds plus the rests between them (there is no rest after the last round), plus 10 seconds to get ready. The timer shows it under the settings.
| Setup | Round | Rest | Rounds | Total time |
|---|---|---|---|---|
| Pro | 3 min | 1 min | 12 | 47 min |
| Amateur | 3 min | 1 min | 3 | 11 min |
| Women's pro | 2 min | 1 min | 10 | 29 min |
| MMA | 5 min | 1 min | 3 | 17 min |
| MMA title fight | 5 min | 1 min | 5 | 29 min |
| Muay Thai | 3 min | 2 min | 5 | 23 min |
| Bag work | 3 min | 30 s | 6 | 20 min 30 s |
These are common formats, not official rules. Your gym, coach or event may use other times — type them in, and the timer remembers them.
The sounds, step by step
- Get ready — 10 seconds, with beeps on 3, 2, 1
- Bell — the round starts
- Clapper (two quick wooden claps) — 10 seconds left in the round
- Three bells — the round is over, the rest starts
- Beeps 3, 2, 1 — the next round is about to start
- Three bells after the last round — the session is done
Everything you hear is made by your browser (Web Audio), so there is nothing to download. Turn off Bell and clapper sounds if you only want the screen.
Frequently asked questions
How long is a boxing round?
In men's professional boxing, a round is 3 minutes with 1 minute of rest. Women's professional rounds are often 2 minutes. Amateur bouts and training plans vary, so the timer lets you set any length.
What is the clapper for?
It warns you that 10 seconds are left, so you can push hard to the end of the round. Some gyms use 30 seconds — pick it in Warning before the round ends.
Does the timer keep going if I switch apps?
Yes. The timer works from the clock, not from counting ticks, so the rounds stay on time in a background tab. Keep the tab open, and allow notifications to see each change.
Can I use it for MMA, kickboxing or Muay Thai?
Yes. Tap the MMA or Muay Thai setup, or type your own round and rest times. Kickboxing often uses 3 × 2 or 3 × 3 minutes.
Can I use it on a TV in the gym?
Yes. Open the page on a laptop or a smart TV browser and press Fullscreen. The colours change with each part, so you can see from far away if it is a round or a rest.
