Free BJJ Timer — Rounds, Rest & Competition Match Lengths
A free jiu-jitsu round timer built for the gym wall: pick a preset or set your own rounds and rest, then cast it full screen so the whole mat can read it. It works offline once loaded, so a flaky gym Wi-Fi connection never stops the clock.
How long are BJJ matches?
Competition match length depends on the ruleset and, in the gi, on belt rank. IBJJF adult match times run:
| Belt (adult) | Match length |
|---|---|
| White | 5:00 |
| Blue | 6:00 |
| Purple | 7:00 |
| Brown | 8:00 |
| Black | 10:00 |
In no-gi, ADCC matches are 10 minutes, with 20-minute championship finals. Points are only scored in the second half, and a draw goes to overtime.
Open-mat rounds vs. competition prep
For open mat, longer rounds (5–6 minutes) with short rests build the pace and problem-solving you actually use while rolling — the Open Mat presets cover this. For competition prep, match the exact format you'll face: set one round to your belt's IBJJF time, or use the ADCC preset, and drill going hard from the first whistle with no rest to fall back on. Alternating both through a training week keeps your gas tank honest and your timing sharp.
