Morse Code Timing — WPM, PARIS Standard, Dot & Spacing Rules
Dots and dashes are only half of any message — the silences between them decide where letters end and words begin. Here you will find the standard Morse code timing ratios, the PARIS 50-unit yardstick behind every words-per-minute figure, and the Farnsworth timing method that lets learners train at honest character speeds.
How Morse Code Timing Works
A Morse message runs on two channels at once: the bursts of signal you can hear, and the measured quiet between them. That quiet is not decoration — it announces where an element stops, where a character closes, and where one word hands over to the next. Hold the proportions steady and a listener separates all three layers without effort; let them drift and even a short word smears into guesswork.
The proportions come from the International Telecommunication Union, whose ITU-R M.1677 recommendation describes the code in units of a single dot. Every other duration in the system is that one unit multiplied, which is why a single slider on the calculator below can rebuild the entire table for any speed.
New to the patterns themselves? Learn the shapes first on the morse code alphabet page. Then come back, generate practice text with the morse code translator, and open morse code sounds to hear these ratios performed at several speeds.
The 1–3–1–3–7 Morse Code Timing Rule
Five durations govern everything, and each is a small whole number of dot-units. Memorize this handful of ratios and any speed anyone quotes becomes a quick mental calculation.
Dot
1 Unit
The unit every other duration is measured against.
Dash
3 Units
Held for exactly three dot-lengths.
Inside Character
1 Unit
The breath between elements of one letter.
Between Letters
3 Units
The pause that closes a character.
Between Words
7 Units
The longest silence in standard sending.
Why the Ratios Matter
Worked at the common 20 WPM setting, a single unit lasts 60 milliseconds, so a dash and a letter gap each take 180 milliseconds and words rest 420 milliseconds apart. Raise or lower the speed and every figure scales together — the pattern of proportions itself never changes.
Theory turns into skill only through the ear, so carry these numbers to the morse code sounds page for listening drills, or feed your own sentences into the morse code translator and study the gaps it leaves.

Farnsworth Spacing
Characters can stay brisk while the message slows down: hold them at 20 WPM, stretch only the silences, and the effective pace drops. Choose that effective pace here to see the letter and word gaps it produces.

Dot Stays at 20 WPM
The arithmetic: of the fifty units in PARIS, thirty-one belong to the characters and nineteen to spacing. Characters keep the 20 WPM unit of 60 ms untouched, while each spacing unit inflates to 165 ms so the whole word occupies the time it would at 12 WPM. The letters never slow down — the quiet between them does the work.
How to Calculate Morse Code Timing
Every WPM figure traces back to one reference word: PARIS, chosen because its pattern fills exactly fifty units under the standard convention.
Dot duration formula
1200 ÷ WPM = milliseconds
Worked example: 1200 ÷ 20 gives a 60-millisecond dot at 20 WPM, and each remaining duration is a plain multiple of that single result.

Precomputed rows for the speeds learners actually use, from slow practice to brisk operating. Every entry comes from the same division — 1200 by the WPM figure — so this table and the calculator above always agree.
| Speed | Dot | Dash | Inside Character | Letter Gap | Word Gap | Practice Use |
|---|---|---|---|---|---|---|
| 5 WPM | 240 ms | 720 ms | 240 ms | 720 ms | 1680 ms | Slow practice |
| 10 WPM | 120 ms | 360 ms | 120 ms | 360 ms | 840 ms | Beginner practice |
| 15 WPM | 80 ms | 240 ms | 80 ms | 240 ms | 560 ms | Moderate practice |
| 20 WPM | 60 ms | 180 ms | 60 ms | 180 ms | 420 ms | Common practice speed |
| 25 WPM | 48 ms | 144 ms | 48 ms | 144 ms | 336 ms | Fast practice |
| 30 WPM | 40 ms | 120 ms | 40 ms | 120 ms | 280 ms | Advanced practice |
Farnsworth Timing Method Explained
Farnsworth timing exists to solve a learning problem: characters heard too slowly get memorized as separate dots and dashes, and that habit shatters at real speeds. The fix keeps each character's internal rhythm intact — sent at a confident pace — while padding the space around it, so the overall message still arrives gently.
Standard Timing
Under standard timing the whole message breathes together: pick a lower WPM and dots, dashes, and gaps all lengthen in proportion.
Farnsworth Timing
Farnsworth sending freezes the characters at their chosen speed and pours the extra time exclusively into the gaps between letters and words.

Morse Code Speed Levels: Beginner to Proficient
A WPM number means little until you have felt it through headphones. These three bands are the ones instructors reach for when placing a student: recognition first, then plain-language copy, then real-time conversation.
| Level | Speed | What It Looks Like |
|---|---|---|
| Beginner | 5–13 WPM | Characters are still being translated piece by piece. Keep them at 15–20 WPM with Farnsworth spacing so the sound stays truthful while the pace remains kind. |
| Novice | 13–15 WPM | Most letters now arrive without counting, familiar short words register as single sounds, and slow, clean practice transmissions can be followed end to end. |
| Proficient | 20+ WPM | Copy keeps up with live conversation, words register whole instead of letter by letter, and a relaxed contact at standard spacing feels unhurried. |
