String Hight Faults

The fretboard is calculated for an ideal instrument with no string height (action). When the strings are elevated by the bridge to be playable, we introduce a fault. We have to press the strings down to the frets. The tension increases and the note will be sharp. What few thought of is that there also is, for several reasons, a string height at the nut.

At the bridge we compensate this by lengthen the strings.
At the nut we compensate for the string height by shortening the distance between the nut and the first fret.
