String Equispacing Calculators

Contrary to popular belief, the strings in a guitar should not be spaced uniformly. It is the space between adjacent strings that must be uniform, not the distance between their centers.

These calculators (there are two, for six and seven string guitars) work also for those players using alternate tunings that may alter the usual thin-to-heavy string gauge ordering.

  First you must enter the distance between the centers of the 1st and 6th strings (or 1st and 7th). This is usually expressed in millimeters (default), but you may enter it in inches. An usual value for the nut is displayed by default. Decimals must be expressed with ".".

Second, enter the string gauges. These are usually given in inches (default), but you may enter them in millimeters. Usual values are displayed by default. You can find these values, many times both in inches and millimeters, in the string packaging of your choice. Decimals must be expressed with ".".

Finally, press the "Calculate" button. Again, you can obtain the results in inches or millimeters. To gain precision, the measurements are all referred to the center of the 6th string.

Notes:

- If you play with odd values you will obtain odd results. Pay attention to the Inches/Millimeters buttons.

- The precision in the results is limited to 4 significant digits. This is much more than enough for your physical measuring precision.

- Sorry, this calculator doesn't handle fractional inches.
