Key takeaways
- C Standard is C–F–A-sharp–D-sharp–G–C from low to high; it is not the same layout as Drop C.
- Every string moves four semitones below E Standard, leaving about 63% of its former tension unchanged.
- Standard-scale guitars generally need heavier sets; 26.5- to 28-inch scales can use smaller gauges.
- Choose a plain or wound third deliberately, then complete the setup at the final tuning.
How to use this: Use these recommendations to compare options, then check the final set against the string maker's specifications and confirm that it suits your instrument.
Quick answer
Compare 11–54 through 12–60 for C Standard
C Standard lowers every string four semitones from E Standard, so the whole set needs attention rather than only the low string. On a 25.5-inch guitar, an 11- or 12-based set with a low string around .054–.060 is a useful range to calculate.
All six strings are four semitones below standard.
Choose by desired bends, attack, and low-end control.
Only the lowest note is shared between the two tunings.
How to calculate C Standard string gauge
Calculate an E-standard set you know, then lower all six notes by four semitones. Use those original values as targets and allow different rounding choices for plain and wound strings.
- Enter the familiar E-standard scale, gauges, and construction choices.
- Save every per-string result before changing the tuning.
- Load C2–F2–A♯2–D♯3–G3–C4.
- Solve toward the original profile, then round to sold gauges.
- Recalculate the complete rounded set before planning the setup.
Worked example: scaling a 10–46 reference set
A four-semitone drop leaves the same string at about 63.0% of its original tension. For equivalent construction, preserving tension requires about 1.26 times the diameter, putting a .010 near .0126 and a .046 near .058.
That relationship explains the common move toward a 12-based set, but the real wound strings still need individual calculation.
| Standard reference | Theoretical C-standard match | Practical comparison |
|---|---|---|
| .010 plain E4 | About .0126 at C4 | .012 or .013 |
| .017 plain G3 | About .0214 at D♯3 | .020, .021, or wound option |
| .046 wound E2 | About .058 at C2 | .056, .058, or .060 |
Do not copy a Drop C set without checking the upper five
Drop C keeps the upper five a whole step higher than C Standard. A set designed for Drop C can therefore leave the C-standard upper strings much softer than intended.
- Confirm every open note rather than choosing by the shared low C.
- Use a wound third when stability matters more than wide bends.
- Let a longer baritone scale reduce the amount of gauge required.
- Complete nut, relief, action, and intonation work at C Standard.
C Standard starting sets
These ranges preserve a conventional high-to-low progression while accounting for scale length.
| Scale | Light | Balanced | Firm |
|---|---|---|---|
| 24.75 in | 12–16–22w–34–46–60 | 13–17–26w–36–48–62 | 14–18–28w–40–52–66 |
| 25.5 in | 11–15–20–32–44–58 | 12–16–24w–34–46–60 | 13–17–26w–36–48–62 |
| 26.5 in | 11–14–19–30–42–56 | 12–16–22w–32–44–58 | 13–17–24w–34–46–60 |
| 27–28 in | 10–13–18–28–40–52 | 11–15–20–30–42–56 | 12–16–22w–32–44–58 |
The upper five strings match Drop B’s recommended gauges. C Standard sits a semitone lower on those five strings, so the same wire carries roughly 12% less tension there than it does in Drop B.
C Standard versus Drop C and Drop B
C Standard is C–F–A-sharp–D-sharp–G–C from low to high. Drop C is C–G–C–F–A–D.
They share the same low note, but Drop C keeps its upper five strings one whole step higher. A set optimized for C Standard can therefore feel overly firm on those five strings in Drop C.
Drop B is the closer relative: same shape, every string one semitone higher. A C Standard set works on a Drop B guitar and vice versa; the only difference is that extra semitone of tension across the board.
Choosing standard or baritone scale
Standard 24.75- and 25.5-inch guitars can support C Standard with heavier sets. A 26.5- to 28-inch scale allows smaller gauges and may improve low-string articulation, but raises treble-string tension at the same gauge. Build the set around both ends rather than choosing one uniform label.
Setup and intonation
Moving from E Standard to C Standard usually changes total pull, nut fit, and saddle positions enough to warrant a dedicated setup. A wound third can improve stability in medium and firm sets.
- Every string moves here, not just the low one, so budget for a full relief and intonation pass rather than a quick single-string touch-up.
- A wound third changes that string’s intonation-compensation needs specifically; set its saddle after the rest of the set settles.
- C Standard and Drop B share the same low-string weight, so a guitar set up for one does not need a second full setup for the other.

Technical references
Use these manufacturer references when you need product-specific tension or setup information. They were last reviewed on ; the gauge suggestions on this page remain starting points because strings and instruments vary.
Before you change strings
Save your current setup, change one variable at a time, and recheck tuning, neck relief, action, and intonation after the new strings settle. If a result looks inconsistent with your instrument or a manufacturer's data, send the setup details through the contact page.
