Fretboard Diagram Sheet

Create a blank fretboard diagram with a chosen number of strings or courses and fret intervals. Use it to map scale positions, chord shapes or lesson notes without mistaking a schematic for an instrument building template.

Sheet settings

A mandolin is usually diagrammed as four courses.

Equal diagram spacing is for notation, not instrument construction.

Understanding the layout

The diagram uses equal spacing for fret intervals so positions are easy to mark and label. A real fretboard does not use equal physical fret spacing. The heavy starting line is a visual reference, and the numbered intervals identify positions in the diagram. The selected string or course count should match the instrument notation convention you intend to use.

Using the sheet

Write the tuning and the position being studied before adding dots or note names. Use a consistent symbol for a root note and another for related tones, then add a small key. For a mandolin, four course lines can be more appropriate than eight separate string lines. Keep a separate copy for another tuning rather than placing incompatible note maps on the same blank diagram.

Choosing the settings

Instrument strings / courses sets the number of horizontal lines. Frets per diagram sets the number of vertical intervals. The page is laid out for a long schematic, with landscape orientation as a useful starting point. More frets make the intervals narrower, so choose a readable count and inspect any handwritten labels before using a dense diagram.

A practical example

Choose six strings and twelve frets. Download the SVG and count six horizontal string lines and twelve fret intervals. Mark a simple position pattern using independently checked notes, then label the tuning and the meaning of your symbols.

Before you print

The generator does not calculate note names, solve scales or validate fingerings. Its equal spacing is not suitable for placing frets on a real instrument. It is a blank educational diagram.

Common question

Can I use this as a full size fret cutting guide?

No. The fret spacing is deliberately schematic and equal. Instrument construction requires scale length calculations and precise measurements.
