How to Find Chords for B Major
The notes of a B major scale are:

Now we’ll build a “1 – 3 – 5” chord off each note of the scale, using only the notes of the scale to build the chords.
So starting on B, we’ll count “1 – 3 – 5” to build our first chord. When we do this, we get our first chord: B – D♯ – F♯
Then we’ll start on C♯ and do the same thing. We’ll build a “1 – 3 – 5” chord using only the notes of the scale. When we do, we get: C♯ – E – G♯
Next we’ll start on D♯, and using only the notes of the scale, we’ll build another “1 – 3 – 5” chord: D♯ – F♯ – A♯
We can continue following this pattern, building a chord off each note of the B major scale, and using only the notes of the scale to build the chords.
