Morse Code Speed (WPM)
Everything on this page runs in your browser — nothing you type is sent anywhere.
What words per minute really means
Morse Code speed is measured in words per minute, usually shortened to WPM. One standard word is PARIS, chosen because it takes exactly 50 timing units to send: the letters P, A, R, I and S plus the word gap after them add up to 50 dots, dashes and gaps counted in units. So a speed of 20 words per minute means 1,000 units per minute, or one unit every 60 milliseconds.
That definition matters because it stops speed from being a vague feeling. Two operators who both claim 20 WPM are, in theory, sending at the same unit length, even if one sends with a key and the other with a computer. In practice, uneven timing makes a real signal harder to copy than its nominal speed suggests, which is why rhythm matters as much as raw pace.
What speed should you aim for
A beginner who can copy comfortably at 5 to 10 words per minute is doing well, because the first goal is accuracy, not pace. Most everyday amateur radio Morse contacts happen around 12 to 25 words per minute, and contest operators often go faster, but there is no prize for jumping to 25 before 12 feels easy.
A useful rule is to raise speed only when you can copy at your current speed with about 90 percent accuracy over several minutes. If accuracy collapses when you go faster, you have not actually learned the faster speed; you have just started guessing. Drop back, rebuild accuracy, and try the higher speed again in shorter bursts.
How to get faster without guessing
Practise at two speeds, not one. Spend most of your time at a comfortable speed where you copy almost everything, and add short bursts, perhaps two minutes at a time, at a speed just above your comfort zone. The bursts teach your ear the faster rhythm, while the comfortable practice keeps accuracy honest.
Use real words and callsigns rather than random letters once the alphabet is known. Random groups are harder than words because your brain cannot use context, and they teach you to copy letter by letter instead of hearing whole words. When a word starts to arrive as one sound instead of a string of letters, your effective speed has jumped even if your unit speed has not changed.
Measuring your speed honestly
The speed test on this site measures accuracy, correct and incorrect letters, and time, and keeps your best score in this browser only. Use it as a check-in, not as your main practice: take it at the start of a session, practise, then take it again at the end of the week and compare. A single fast run on easy material tells you less than a steady score on mixed material over several weeks.
Remember that sending speed and copying speed are different. Many operators can send faster than they can copy, because sending lets you choose the next letter. Judge your progress by copying, which is the harder and more useful measure, and let sending catch up with separate key practice.
Frequently asked questions
What is a good Morse Code speed for a beginner?
Copying accurately at 5 to 10 words per minute is a solid beginner level. Everyday amateur contacts commonly run at 12 to 25 words per minute, so that range is a realistic medium-term goal.
Why is PARIS the standard word?
PARIS takes exactly 50 timing units to send, including its word gap, which makes the maths clean: words per minute times 50 gives units per minute. Any other word would give a messier standard.
How long is a dot at 20 WPM?
At 20 words per minute, 1,000 units are sent per minute, so one unit, and therefore one dot, lasts 60 milliseconds. A dash lasts three units, or 180 milliseconds, at the same speed.
Should I use Farnsworth spacing to go faster?
Farnsworth spacing, with longer gaps between characters, helps beginners recognise letters at full character speed. To raise overall speed, shorten those gaps gradually until the spacing matches normal sending.
