String Equispacing Calculators


Most guitar makers will set the string slots both in nut and bridge so that it is the space between adjacent strings that is uniform, not the distance between their centers.

These calculators 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 outmost strings. 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 lowest string.

Notes:

- You must allow your navigator to run the active content of this page.

- 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.
