Standard Tuning for Guitar
Strings run E2 A2 D3 G3 B3 E4, in playing order. Tune by microphone below, or read the exact frequencies and what changes from standard guitar tuning.
Select a note to lock the tuner to that string, or use automatic matching.
Synthesized reference tones at A4 = 440 Hz. Playback pauses the microphone to avoid measuring the speaker. Start the mic again when you are ready.

Try the reference tones from string 6 to string 1: E2, A2, D3, G3, B3, E4. Select one string before retuning it, pluck once, let it settle, then check the meter. Compare the two E strings: they should sound two octaves apart. Recheck all six after your last adjustment.
Getting to Standard from standard
This is the reference tuning for Guitar, so nothing changes. Every other tuning on this site is described relative to these notes.
Why players use Standard
The reference every other guitar tuning is described against. Its intervals are all perfect fourths except between the third and second strings, which is a major third — an inconsistency that makes chord shapes awkward to transpose but keeps scale fingerings compact enough to play across all six strings without shifting.
The interval structure of Standard
Reading upward, the gaps are a fourth, a fourth, a fourth, a major third, then a fourth. That single major third between the G and B strings is the compromise that defines the instrument: pure fourths throughout would make every scale shape identical across the neck, but would push the outer strings a fret further apart than they sit now. The consequence is that a shape moved across the third-to-second string boundary needs one finger shifted a fret, which is why guitarists memorise chord grips as pictures rather than deriving them. The upside is the familiar CAGED system and the fact that the outer strings share a name two octaves apart, giving an unambiguous octave reference on either side of the neck.

What frequency is the E2 string?
E2 is 82.41 Hz at concert pitch (A4 = 440 Hz). That's the fundamental — the string also produces harmonics above it, which is why a tuner reading the wrong octave usually means it locked onto a harmonic rather than the fundamental. This is the lowest string in this guitar tuning.
