Double Bass Upright Bass Fingerboard radius

[savoy]

Good Day,

I am interested in finding 'design specifications' for Upright basses.

Also, specifics about fingerboards. Typical lengths, nut & bridge widths, and commonly used radius.

Such information available?

Thank you, Thomas

I'll take a stab at this: Typical length is about 34" or 864mm. Nut is 39-44mm, bridge spacing 25-28mm. Spacing at the nut 10-11mm. The radius is compound, and varies widely. Most good luthiers have a set of "optimum" templates they use for the fingerboard ends. In general, a jazz player can use a flatter fingerboard than a classical player (I'm talking about the lateral arch, not the camber).
