Choose the one statement that fits you best to see its grade.

A grade is a description, not a diagnosis. The next step is a conversation with a licensed clinician, who reads it alongside your history, not on its own.

A screen, not a diagnosis.

The mMRC dyspnea scale describes how much breathlessness limits everyday activity. It cannot diagnose a lung condition or anything else, and it cannot say why you are short of breath. Only a licensed clinician can make a diagnosis, and they read a grade alongside your history and an examination, not instead of them. This tool is for adults.

If you are struggling to breathe right now, or breathlessness came on suddenly or with chest pain, call 911 or go to the nearest emergency room.

Methodology

How this is calculated
The scale has five statements, graded 0 to 4, and you choose the one that fits you best. The grade of that statement is the result. Nothing is added up, and this page puts no category, stage, or threshold on the grade.
Where the data comes from
The scale's developer references, as ePROVIDE lists them: American Thoracic Society. Am Rev Respir Dis 1982;126(5):952-6. Mahler DA, Wells CK. Chest 1988;93(3):580-6. GOLD footnotes the scale to: Fletcher CM. BMJ 1960; 2: 1662. The instruction line and the five statements are reproduced word for word from Table 2.5 of the GOLD 2018 pocket guide. Other printings of the scale differ in small ways, such as “100 yards” for “100 meters”; this page follows GOLD 2018 throughout. The ePROVIDE listing for the scale states: “This questionnaire is in the public domain.”

What this does not account for
Everything a clinician asks beyond this one question: how long you have been short of breath, cough, wheeze, chest pain, smoking, your medical history, your medications, and an examination and breathing tests. The grade describes breathlessness during activity only.

What the grade is

The grade is the number of the statement you chose, from 0 to 4. A higher grade means breathlessness stops you sooner in everyday activity. Clinicians use the grade to describe breathlessness the same way from one visit to the next, and to see whether it changes over time.

Why the wording is not edited

The mMRC scale is a published questionnaire, and its grades mean what they mean because people choose among these statements in this wording. So the instruction line and the five statements are reproduced exactly as GOLD 2018 prints them, including the capitals, rather than rewritten in Temi's voice the way the rest of this page is.

Nothing here is stored

Your answers stay in your browser. They are not sent to Temi, not saved, not attached to you, and not recorded in any session replay, and closing the tab clears them. Temi knows only that someone opened this tool, the same thing it knows about every page.

Copying the result link is the one way your answer leaves your browser, and you decide when. The link carries the grade you chose in the part of the address after the “#”, which browsers never send to a web server, so Temi still never sees it. Anyone holding the link can open it and read the answer, so send it only to someone you mean to show.

If you want to act on what you see, the useful next step is a conversation with a clinician who knows you, or one you can get to. Temi does not prescribe controlled substances.
