String Calculator

powered by Lauri Niskanen's // contributor Cuerdas Pulsadas

  • Certain instruments might require adjustments on the bridge, nut or both to fit certain gauges.
  • Check out the equivalences in case you are looking for other brands or string types.
  • Check out the diameters to know more about the actual diameters for certain string types.
1. Select Instrument & Base Setup

Choose your instrument from the main dropdown in the "Setup" section. Then, set the desired a' pitch (Hz) and adjust the default string lengths (cm) for each string group (e.g., Fingerboard, Extension).

2. Global Adjustments

Use the controls in the "Settings" section to make broad changes:

  • Transpose Tuning: Shift all notes up or down using the +/- buttons or semitone input.
  • Adjust Tension: Apply a global offset (Kg) to all strings relative to their base tension using the +/- buttons or input.
3. Fine-Tune Individual Strings

In the results table, modify each string as needed:

  • Change the Note using the text input or the / buttons.
  • Adjust the specific Tension (Kg) using its number input field.
4. View Results & Materials

The table automatically calculates string diameters. Toggle checkboxes in the "Settings" section to show/hide columns for different materials (Nylon, Carbon, etc.). Check the Total Tension displayed above the table.

Advanced: Manage Courses

Modify the instrument's string layout:

  • Click below the table to add a new string course.
  • Click on a row to remove a string (or pair).
  • Use / to reorder courses.
5. Export Data
