Quick answer

Use the visual calculator

Calculate expanded character and word gaps for Farnsworth practice while preserving faster character formation, and verify whether the requested effective speed is mathematically possible.

Worked example: Character speed 20 WPM and effective speed 10 WPM keeps 60 ms dots but lengthens the spacing between characters and words.

How this visual Morse calculator works

The page separates input, transformation and verification so the result remains understandable.

1. Enter

Character WPM is supplied using the calculator-specific controls.

2. Normalize

The browser validates symbols, timing values, separators, files or device permissions required by this method.

3. Calculate

Characters retain the dot unit 1200/character-WPM. Extra time needed to reach the effective PARIS word duration is assigned to the four inter-character gaps and one inter-word gap according to the selected distribution.

4. Visualize

The farnsworth bars display reveals the signal structure instead of presenting only a text answer.

5. Verify

Compare the mapping, timing units, decoded characters, measured pulses or design dimensions shown in the result.

Method, timing and worked example

The calculation follows the rule appropriate to this individual tool.

Method used
Characters retain the dot unit 1200/character-WPM. Extra time needed to reach the effective PARIS word duration is assigned to the four inter-character gaps and one inter-word gap according to the selected distribution.

Worked example

Character speed 20 WPM and effective speed 10 WPM keeps 60 ms dots but lengthens the spacing between characters and words.

Change the inputs to reproduce or extend the example
Standard timing reference: At ordinary International Morse timing, a dot lasts one unit, a dash three units, the gap inside a character one unit, the gap between characters three units and the gap between words seven units. The WPM tools use the PARIS timing convention, while Farnsworth mode lengthens spacing without slowing individual dots and dashes.

Important limitations

Effective WPM cannot exceed character WPM in Farnsworth practice.

For camera, microphone, audio and image analysis, signal quality and browser support affect the result. Treat uncertain output as a candidate interpretation and verify it against the source.

Farnsworth Morse Timing Calculator questions

Answers to common questions about the calculation and visual result.

What does the Farnsworth Morse Timing Calculator calculate?
Calculate expanded character and word gaps for Farnsworth practice while preserving faster character formation, and verify whether the requested effective speed is mathematically possible.
Which Morse standard does this tool use?
The calculator uses International Morse code for supported letters, digits, punctuation and common procedural signals. Timing follows the standard one-unit dot, three-unit dash, one-unit element gap, three-unit letter gap and seven-unit word gap unless a dedicated timing control changes spacing.
How should I read the visual result?
Dots appear as short circular or short-duration marks, while dashes appear as longer bars or pulses. The live visual is synchronized with the text result so each transformation can be inspected instead of accepted as an unexplained answer.
Does this calculator upload my message or recording?
Calculations run in the browser. Camera, microphone, audio and image tools process the selected stream or file locally in the page; the plugin does not send those inputs to a calculation server.
What can affect accuracy?
Effective WPM cannot exceed character WPM in Farnsworth practice.
Can I use the result for practice or design?
Yes. Copy and print controls are included, and tools that create reusable audio, vector, image or stencil output provide a download control. Verify any safety-critical or permanent design before relying on it.
