D to G is a perfect fourth (5 semitones), G to A is a major second (2 semitones). The third is replaced by the fourth (G), which wants to fall to the third. With G in the bass the same three keys read as Gsus2.

Dsus4 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 D as its lowest note.

The barre shapes 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 suspended fourth chords on other roots.

Inversions of Dsus4

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.

Where Dsus4 fits

A sus chord has no third, so it is neither major nor minor and has no fixed place in a key. Dsus4 usually resolves to D or Dm: the fourth, G, falls a half or whole step to the third. Its most common job is Vsus4 in G major, delaying the V chord: Dsus4 → D → G.
