Print or Metal Lasercut as a thin radius guide,
or export to Openscad to make a longer 3d printed neck support or sanding block.
Sizes:
Ukulele - typically flat
Guitars - 7.25 to 20inches (Classical is flat)
Violins,Cellos - typically have compound radii to accomodate natural finger reach.
Typical ruler set: 7.25, 9.5, 10, 12, 14, 15, 16, 20
- Fender strat vintage - 7.25 (184.1mm)
- Fender strat modern - 9.5 (241mm)

This is a helper tab. It does not contribute to drawing the Fret Ruler/Neck.
It shows you all the scala files matching the search filters below. Enter the filename on the first tab.
This search only works if you can see this tab.
There may be >4000 scala files. So choose wisely.

USE:
Export as PDF, print in Poster mode for full scale drawing.
Glue onto fretboard and cut - or lasercut Router template.
Methods:
12th Root of 2 - 'preferred' method for even temperment scales.
Note: 12th Root of 2 and the 17.817 give identical results.
17.835 is similar (unrounded calculation) to 17.817, and has max 0.2mm difference in a 24 inch scale.
Markers:
Fret markers are located at different positions based on instrument tuning. (Double entry draws two markers)
E.g. for Ukulele these are common variants:
[3,5,7,10,12,12] (17 frets),
[3,5,7,7,10], [5,7,10], [5,7,12]
[5,7,10,12,15] (19 frets)
Nut Compensation:
Moves the Nut forward a small amount, so that fret1 can have better intonation if Nut shape tuned per string.
Scala filenames:
Are in the scala subdirectory of inkscape extensions. More(>4000) at www.huygens-fokker.org/scala
Neck Curvature Ruler:
Necks can have one radius (e.g. 7.25) at the nut and a wider radius (e.g. 12) at the body.
This called a Conical radius (incorrectly a compound radius). It enables easier single string control at the Nut and chords nearer the body.
Fretboard lengths:
Guitar scale lengths are usually between 24" and 26".
Bass scale lengths generally stay between 30" to 36".
Common scale lengths:
Banjo - 26_3/16 (665.2mm)
Mandolin - 13_7/8 (335mm)
Ukulele concert - 15 (381mm)
Ukulele soprano - 13_3/4 (349.25mm)
Ukulele tenor - 17_3/32 (434.2mm)
Ukulele Baritone - 20_1/8 (511.2mm)
