Yoga Breathing Ratio Calculator
Turns a pranayama count pattern (inhale, hold, exhale, hold) and the length of one count into breaths per minute, so you can see how slow a pattern really is.

About this calculator
A pranayama ratio such as 4-7-8 or 4-4-4-4 (box breathing) says how many counts each phase lasts. Adding the phases gives the length of one breath, and that sets the breathing rate:
Cycle (seconds) = (inhale + hold + exhale + hold after exhale) × seconds per count Breaths per minute = 60 ÷ cycle
How to read it
Adults breathing on their own at rest usually take 12 to 20 breaths a minute. Slow-breathing practices aim lower. Around 6 breaths a minute (about 4.5 to 7 for most people) heart rate and breathing fall into step, a pattern called resonance breathing that increases heart rate variability. Long breath holds bring the rate lower still.
Safety
Breathing exercises should feel comfortable. Stop if you feel dizzy, short of breath or anxious, and skip long breath holds if you are pregnant or have heart, lung or blood-pressure problems unless your doctor agrees. This is general information, not medical advice.
How to use
Enter the counts for each phase and how long one count lasts. Default 4-7-8 at one second per count: a 19-second cycle, so 60 ÷ 19 = 3.16 breaths per minute. Box breathing 4-4-4-4 at one second per count is a 16-second cycle, 3.75 breaths per minute. Inhaling for 5 and exhaling for 5 with no holds is a 10-second cycle, exactly 6 breaths per minute, the usual resonance-breathing pace.
Frequently asked questions
What is a normal breathing rate?
At rest, adults usually breathe 12 to 20 times a minute. Slow-breathing exercises typically aim for about 6 breaths a minute, and patterns with long holds go lower.
What is resonance breathing?
Breathing at about 6 breaths a minute, where heart rate, breathing and blood pressure rhythms line up and heart rate variability is highest. The exact rate differs between people, usually between 4.5 and 7 breaths a minute.
How long is one count?
Most teachers mean about one second, but counts often run slower as you relax. Time a few cycles with a clock and adjust the count length to match.
Are breath holds safe?
Short holds are fine for most healthy adults. Build them up gradually, never strain, and avoid long holds if you are pregnant or have heart, lung or blood-pressure conditions unless your doctor agrees.
