Epworth Sleepiness Scale Calculator

Rate your chance of dozing in each situation to get your Epworth score.

How it is calculated

The score is a plain sum of eight answers, each a whole number from 0 to 3: score = reading + TV + public place + passenger + lying down + talking + after lunch + traffic, giving 0 to 24. Answers mean 0 = would never doze, 1 = slight chance, 2 = moderate chance, 3 = high chance. The tool then names a band: 0 to 5 lower normal, 6 to 10 higher normal, 11 to 12 mild, 13 to 15 moderate and 16 to 24 severe excessive daytime sleepiness. Any answer outside 0 to 3 gives no result, and a question left out is counted as 0. The score is a screening aid for how sleepy you feel in daily life, not a diagnosis, and it says nothing about the cause.

Worked example

Ratings: reading 2, watching TV 3, sitting in a public place 1, car passenger 2, lying down in the afternoon 3, talking to someone 0, quiet after lunch 2, stopped in traffic 1. Total: 2 + 3 + 1 + 2 + 3 + 0 + 2 + 1 = 14 / 24. A total of 13 to 15 falls in the moderate band, so the category reads moderate excessive daytime sleepiness. It would be worth discussing a score like this with a doctor.

Common mistakes

  • Rating how tired you feel in general instead of how likely you are to doze in each specific situation; the scale asks about dozing, not tiredness.
  • Scoring a situation that does not apply to you, such as traffic when you never drive, as 0 without imagining it; the usual advice is to picture how it would affect you.
  • Answering for your best day or after an unusually good night rather than for your usual recent life.
  • Using a total above 10 as a diagnosis of a sleep disorder: the score only suggests sleepiness is high, and the cause needs a clinician.
  • Leaving questions unanswered and reading the total as complete: a skipped question counts as 0 and lowers the score.

About this calculator

The Epworth Sleepiness Scale, developed by Dr. Murray Johns in 1990, is a short self-assessment that scores how likely you are to doze off in eight everyday situations — reading, watching TV, sitting inactive in a public place, riding as a passenger for an hour, lying down to rest in the afternoon, sitting and talking with someone, sitting quietly after a lunch without alcohol, and stopped in traffic for a few minutes. Each situation is rated 0 (would never doze) to 3 (high chance of dozing), and the eight scores sum to a total between 0 and 24.

A total score above 10 is generally considered a sign of excessive daytime sleepiness and is one of the standard first screening tools clinicians use before investigating conditions like obstructive sleep apnea or narcolepsy, though the scale on its own does not diagnose any disorder — it only flags whether daytime sleepiness is high enough to warrant further evaluation. It is widely used in sleep clinics, general practice, and self-tracking because it takes only a couple of minutes and needs no equipment.

Rate your chance of dozing in each of the eight situations, and the calculator totals your Epworth score and shows where it falls.
