Fender Stratocaster Factory Setup Specs: Action, Relief & Pickups
Fender's published Stratocaster setup specs: string height at the 17th fret, neck relief and pickup height, by fretboard radius and pickup type — plus how to measure each one.
Quick answer: Fender's setup spec for a Stratocaster with a 9.5"–12" radius neck is 4/64" (1.6 mm) string height on both outer strings, measured at the 17th fret, with .010" (0.25 mm) neck relief at the 8th fret. A vintage 7.25" radius gets 5/64" (2 mm) bass / 4/64" (1.6 mm) treble and .012" (0.3 mm) relief. Pickup height depends on the pickup type — 5/64" bass / 4/64" treble for standard single-coils. Fender calls these minimum specs for factory strings, not hard rules.
Every number on this page is rendered from Fender's own Stratocaster setup instructions at build time, so the tables can't drift from the source. Each table names how to measure, because the same guitar reads differently at the 12th and 17th frets.

Start with your fretboard radius
Fender's action and relief specs change with the curve of the fretboard, so find your radius before reading any other table. Vintage-style necks are usually 7.25"; most modern Stratocasters are 9.5"; some models use a flatter 12" or compound radius. Your model's spec sheet lists it.
| Model | Fretboard radius | Neck relief | String height, bass / treble (17th fret) |
|---|---|---|---|
| Fender American Professional II Stratocaster | 9.5" (241mm) | 0.010" (0.25mm) | 4/64" (1.6mm) / 4/64" (1.6mm) |
| Fender Player Stratocaster | 9.5" (241mm) | 0.010" (0.25mm) | 4/64" (1.6mm) / 4/64" (1.6mm) |
| Fender Vintera '50s/'60s Stratocaster | 7.25" (184mm) | 0.012" (0.30mm) | 5/64" (2.0mm) / 4/64" (1.6mm) |

String height (action)
Tune to pitch. With a 6" ruler, measure from the bottom of the string to the top of the 17th fret on the low and high E strings. Adjust the saddle height screws to the chart, retune, and play before going lower.
| Fretboard radius | Bass side (17th fret) | Treble side (17th fret) |
|---|---|---|
| 7.25" | 5/64" (2 mm) | 4/64" (1.6 mm) |
| 9.5" to 12" | 4/64" (1.6 mm) | 4/64" (1.6 mm) |
| 15" to 17" | 4/64" (1.6 mm) | 3/64" (1.2 mm) |
On a locking tremolo, individual string heights are preset; Fender says to set overall height with the two pivot screws instead. For the saddle-by-saddle procedure and common measuring mistakes, see the action height guide.
Neck relief
Tune to pitch, put a capo at the 1st fret and press the 6th string at the last fret. Slide a feeler gauge between the string and the top of the 8th fret.
| Fretboard radius | Neck relief |
|---|---|
| 7.25" | .012" (0.3 mm) |
| 9.5" to 12" | .010" (0.25 mm) |
| 15" to 17" | .008" (0.2 mm) |
Turning the truss rod clockwise removes relief; counter-clockwise adds it. If the rod meets heavy resistance or does nothing, stop and have it checked. The Stratocaster truss rod guide covers headstock and heel adjusters and wrench sizes.
Pickup height
Press all strings at the last fret and measure from the bottom of the 1st and 6th strings to the top of the pole piece. Fender publishes pickup height by pickup type, not by position. As a rule of thumb, the gap should be largest on the bass side of the neck pickup and smallest on the treble side of the bridge pickup.
| Pickup type | Bass side | Treble side |
|---|---|---|
| Texas Specials | 8/64" (3.2 mm) | 6/64" (2.4 mm) |
| Vintage style | 6/64" (2.4 mm) | 5/64" (2 mm) |
| Noiseless™ Series | 8/64" (3.2 mm) | 6/64" (2.4 mm) |
| Standard single-coil | 5/64" (2 mm) | 4/64" (1.6 mm) |
| Humbuckers | 4/64" (1.6 mm) | 4/64" (1.6 mm) |
| Lace Sensors | As close as desired | As close as desired |
Treat these as starting points: stronger magnets need more clearance. The Stratocaster pickup height guide covers balancing the three pickups by ear.
Tremolo
For a floating vintage-style or two-point tremolo, Fender's spec is a 1/8" (3.2 mm) gap at the rear of the bridge, set with the spring claw screws inside the back cavity. Retune as you go, because strings and springs pull against each other. If you prefer a decked bridge, balance spring tension so the bridge rests on the body. The Stratocaster tremolo setup guide walks through both.
The order Fender adjusts in
Fresh strings, tuning keys, tremolo, a rough intonation preset, truss rod (relief), string height, pickup height, then fine intonation at the 12th fret. Changing string gauge means going round again: heavier strings pull more relief into the neck.
When to go above these numbers
Fender describes these as minimum specifications for the strings fitted at the factory. Hard pickers, heavier gauges and players who bend a lot often need a little more height or relief to stop buzz. Change one setting at a time and note what you changed.

Frequently asked questions
What is the factory string height on a Fender Stratocaster?
For a 9.5"–12" radius, Fender's spec is 4/64" (1.6 mm) on both the bass and treble side, measured at the 17th fret. A 7.25" radius is 5/64" (2 mm) bass and 4/64" (1.6 mm) treble; a 15"–17" radius is 4/64" bass and 3/64" (1.2 mm) treble.
Where do you measure Stratocaster action, the 12th or 17th fret?
Fender's chart is measured at the 17th fret. Readings at the 12th fret are lower for the same setup, so don't compare 12th-fret numbers against Fender's chart.
What neck relief does Fender recommend for a Stratocaster?
.012" (0.3 mm) for a 7.25" radius, .010" (0.25 mm) for 9.5"–12" and .008" (0.2 mm) for 15"–17", measured at the 8th fret with a capo at the 1st fret and the string pressed at the last fret.
What pickup height does Fender recommend for a Stratocaster?
It depends on the pickup type: standard single-coils 5/64" bass / 4/64" treble, vintage-style 6/64" / 5/64", Noiseless and Texas Specials 8/64" / 6/64", humbuckers 4/64" / 4/64". Measure with the strings pressed at the last fret.
