Introduced in 1898, the 0 (or concert size) is the smallest body size Martin offers. It produces a balanced sound that excels for fingerstyle playing, recording, and accompaniment.

• Width: 13 1/2"
• Depth: 4 1/4"

Martin's 00 is close in size to a nylon/classic guitar's body. It produces a warm, present bass response, perfect for both fingerstyle play and chordal strumming.

• Width: 14 1/8"
• Depth: 4 1/8"

Dating back to 1929, the Orchestra Model (OM) is Martin's second most influential design (along with their dreadnought). Around 1934, the model was seperated into two versions - the long scale OM (25.4") and the short scale 000 (24.9").

Both versions produce rich lows and sparkling highs which make them suitable for just about every style of music.

• Width: 15"
• Depth: 4 1/8"

Martin's Grand Performance body size could be thought of as a modern take on the classic Dreadnought. Its slightly smaller dimensions make it feel a touch less boxy in hand, though it retains the volume, projection, and bass response of a dreadnought, making it perfect for strummers and flatpickers alike.

• Width: 15"
• Depth: 4 1/8"

The 0000 lives in-between an Orchestra Model and a Dreadnought. This body size is known for a complex, balanced sound for strumming and fingerstyle playing, and makes a big sound without the bulk of a dreadnought.

• Width: 16"
• Depth: 4 1/8"

Martin's most iconic body shape was launched in 1931, though it didn't fully take off until 1934 when Martin shortened the body and added a 14 fret neck. This body size is prized for its power, volume, and bass response, making it ideal for strummers (although many have used it for fingerstyle playing too).

• Width: 15-5/8"
• Depth: 4 7/8"
