Nomenclature

This page is to help explain the differences in the names of Martin guitars. Most current models have what we’ll call a Prefix & a Suffix. Such as …

D-18, D-28, 000-18, etc …..

The prefix indicates the body shape. The suffix indicates the style as far as appointments & woods. If there is an “H” in the prefix or suffix it indicates herringbone trim & scalloped braces.

Prefixes ….. (see Dimensions page for specific sizes)

  • “D” or Dreadnought – All “D” guitars are the same size & shape, except for 12 fret guitars which have bodies that are approximately 1” longer.
  • “J” or Jumbo – The largest body size & shape we make. The same depth as the dreadnought.
  • “M” or “0000” – Same dimension as the “J”, but shallower depth.
  • “OM” or Orchestra Model – Smaller upper & lower bout than the “M”.
  • "GP" or Grand Performer - In between the Jumbo & the "OM".
  • “000” or Triple O – Same size as the “OM” with a narrower neck at the nut.
  • “00” or Double O - Smaller upper & lower bout than the “000”
  • “0” or Single O - Smaller upper & lower bout than the “00”

If there is a “C” in the prefix, it indicates a cutaway. If there is an "H" in the prefix, it indicates Herringbone trim & scalloped braces.
