E to G# is a major third (4 semitones), G# to B is a minor third (3 semitones), B to D is a minor third (3 semitones), D to F# is a major third (4 semitones), F# to A is a minor third (3 semitones), A to C# is a major third (4 semitones). A dominant seventh with the thirteenth, C#, on top. The full chord has seven notes and a guitar has six strings, so players keep the root, the third G#, the seventh D and the thirteenth C#, and leave out the fifth, the ninth and above all the eleventh A, which clashes with the third. The thirteenth is the sixth an octave up; it is a 13 and not a 6 chord because the seventh is there.

E13 on the guitar

Standard tuning (E A D G B E). Strings run low E on the left to high e on the right, frets downwards; × is a muted string, ○ an open string, and each dot shows the note it sounds, with the root in blue-green. Every shape below has E as its lowest note.

The E-shape and A-shape grips are movable: an E-shape chord's root is the note under your first finger on the low E string, an A-shape chord's root is the note on the A string. Slide the same grip up or down to play dominant thirteenth chords on other roots.

Inversions of E13

An inversion puts a note other than the root in the bass. The name is what semicord's chord finder calls those notes played bottom to top; a slash name like C/E means a C chord with E in the bass.
