If you are making a fretboard, you need to get your frets in the right position. This online 2-D fret placement calculator will help you do just that. It can accommodate more exotic fretboard designs and supports equal and just temperaments, single and multiple scale lengths, and partial and non-parallel frets (similar to the patented Novax style fretboards). It models frets, fretlets and strings as a system of lines in a two-dimensional plane and then it calculates fret placement on each string in turn.
Once you have generated your fretboard you can export it to an SVG, DXF, PDF or PNG file.
