Breathing Exercise Pacer
Pick a breathing pattern like box breathing or 4-7-8, set a session length, and see cycle length, cycles per session, and breaths per minute.
Breathwork should feel easy. If you feel dizzy or lightheaded, stop and breathe normally. If you're pregnant or have a cardiovascular or respiratory condition, skip the breath holds and check with a clinician before trying a new pattern.
How it works
Pick a pattern and a session length, and the calculator adds up the seconds in one full breath cycle, then works out how many cycles fit in your session and how many breaths that averages per minute. Box breathing inhales, holds, exhales, and holds again for 4 seconds each, so one cycle takes 16 seconds. In a 5 minute session (300 seconds) that works out to 18 full cycles, with a little time left over since 18 cycles only use 288 of the 300 seconds.
4-7-8 breathing runs longer per cycle (4 seconds in, 7 held, 8 out, 19 seconds total), so the same 5 minute session fits 15 cycles instead of 18. Coherent breathing splits evenly into a 5 second inhale and a 5 second exhale, a 10 second cycle, which comes out to 6 breaths per minute, a pace often used as a baseline for calm, steady breathing.
What each pattern is for
Box breathing (4-4-4-4) is a steady, even pattern good for focus before a task or a quick reset during a stressful moment. 4-7-8 stretches the exhale out much longer than the inhale, which tends to wind the body down, so it works well before bed or when you want to settle rather than sharpen. Coherent breathing (5-5) is a simple everyday baseline you can return to any time you notice your breath has gotten short or shallow. Extended exhale (4-6) is a gentler version of the same idea, a small nudge toward calm without a long hold.
Breathe through your nose if you can, both in and out. Nasal breathing slows the pace naturally, warms and filters the air, and tends to keep the breath calmer than mouth breathing does.
FAQ
Do I need to count seconds out loud?
No. Most people find a slow, silent count in their head works fine once they've practiced a pattern a few times. Some people prefer a phone timer with gentle chimes between phases, especially for the longer 4-7-8 hold.
What if I can't hold my breath that long yet?
Shorten the hold, not the inhale or exhale. A 4-5-6 version of 4-7-8 still gives you the long, calming exhale without straining. Holds get easier with practice; there's no need to force the full count on day one.
Should I feel out of breath afterward?
No. Breathwork should feel easy the whole way through. If you feel dizzy, lightheaded, or short of breath, stop and go back to normal breathing. If you're pregnant or have a cardiovascular or respiratory condition, skip the breath holds and check with a clinician before trying a new pattern.
How long should a session be?
A few minutes is plenty to notice an effect. Many people use 3 to 5 minutes before a practice or at bedtime, though there's nothing wrong with going longer once a pattern feels comfortable.
