Building sus2 and sus4 chords is going to take an extra bit of
information. You are going to need to understand how 2 and 4 relate
to our 3 and  3.
Remember that all natural notes are a whole step apart, except
between E-F and B-C. So if we look at a C major scale, the half
steps fall between the 3rd and 4th degrees of the scale, and the
7th and 8th degrees (or 1 an octave higher).

So therefore you can learn to spell any sus2 or sus4 chord by
altering the major and minor chords that you can already spell.
2 = a whole step lower than 3
2 = a half step lower than 3
4 = a half step higher than 3
4 = a whole step higher than 3
So a C chord is C(1), E(3,) G(5).
major =
1 3 5 (C E G)
Knowing that the formula for sus2 is 1 2 5, you
will lower the E(3) to a D(2) in a Csus2 chord.
sus2
= 1 2 5 (C D G)
Knowing that the formula for sus4 is 1 4 5, you
will raise the E(3) to an F(4) in a Csus4 chord.
sus4
= 1 4 5 (C F G)
