Fender Precision Bass Specs: Scale Length and Neck by Model

Quick answer: The Fender Precision Bass has a 34" (864 mm) scale on every model below, from the Squier Classic Vibe to the American Vintage II. The nut is 1.625" (41.3 mm) on most current models; the Squier Classic Vibe '60s is wider at 1.685" (42.8 mm) and the American Vintage II 1960 at 1.70" (43.2 mm). Every model has 20 frets except the American Ultra II, which has 21. The fingerboard radius is 9.5" (241 mm) on most, 7.25" (184.1 mm) on the vintage-style Vintera III and American Vintage II, and a 10" to 14" compound radius on the American Ultra II.

Every number here comes from Fender's spec sheet for that model on fender.com, checked on 21 October 2026. The table is built from those sheets, and each model links to the page its numbers came from.

Fender Precision Bass specs by model

The American Professional rows are the models Fender announced on 13 October 2026, not the 2017 series with the same name.

Scale length: 34 inches on every P-Bass

Scale length is the distance from the nut to the saddles, and it sets how tight each string has to be to reach pitch. Every Precision Bass in the table has a 34" scale, and so does the Jazz Bass, so standard bass sets fit both and feel the same tension. The two differ in the pickups and the neck instead: see Precision Bass vs Jazz Bass, and best strings for Precision Bass before you change sets.

Nut width and neck shape

Most current P-Basses have a 1.625" (41.3 mm) nut: the Standard, Player II, Vintera III, American Professional Classic, American Professional and American Ultra II. Two are wider: the Squier Classic Vibe '60s at 1.685" (42.8 mm) and the American Vintage II 1960 at 1.70" (43.2 mm). If a P-Bass neck feels too broad, the Jazz Bass's narrower neck is the usual alternative. Fender lists Slim "C", Modern "C", Late '60s "C", Modified 1963 "C", 1960 "C" and Modern "D" profiles across the range; the Fender neck profiles guide explains how the letters compare.

Fingerboard radius and frets

The radius describes how curved the fingerboard is from side to side; a smaller number is rounder. Most current P-Basses use 9.5". The Vintera III Late '60s and American Vintage II 1960 keep the vintage 7.25", and the American Ultra II has a compound board that runs from 10" near the nut to 14" higher up. Radius matters at setup time, because Fender's string height and relief starting points change with it: the P-Bass string height guide gives them by radius.

Every model has 20 frets except the American Ultra II, which has 21. The fret wire differs: narrow tall on the Squier and American Professional, medium jumbo on the Standard, Player II, American Professional Classic and American Ultra II, vintage tall on the Vintera III and American Vintage II. Fender's description of fret sizes explains each.

What Fender's spec sheets don't list

Fender's model pages give neck, fingerboard and hardware specs, not body measurements, pickup dimensions or weight. If you need those for a case, a pickguard or a pickup swap, measure your own bass rather than relying on a figure for a different model or year. For how high the split-coil pickup should sit, see P-Bass pickup height.

Not sure which Precision Bass you have?

The serial number gives the year and where the bass was made, which narrows down the model. Try the Fender serial number lookup, or read the Precision Bass serial numbers guide for what each prefix means.
