Acoustic Guitar Case Buying Guide: Dreadnought, Jumbo and OM Sizes

Acoustic cases must match body shape and depth. The three dominant sizes cover most of the market.

Dreadnought

The most common body. Cases are ~41 inches long with deep bodies. Fits most steel-string acoustics.

Jumbo

Wider and deeper than dreadnought. Needs a jumbo-specific case — a dreadnought case will be too tight.

OM / auditorium

Shallower body. OM cases are slightly narrower — check the waist width.

Buyer checklist

  • Measure body length, depth and waist before ordering.
  • Confirm neck support (cradle or foam).
  • Decide hardshell vs padded bag by shipping and storage needs.
