The right acoustic guitar size is the one that lets you reach the fretboard while the body rests against you without stretching your arm. Full-size guitars suit taller players, while 3/4, 7/8 and travel sizes suit smaller frames and travel. Measure your reach and try the sizes below before you pick one.
Start with the body size names
Acoustic guitars come in full size, often called 4/4, and smaller sizes named 3/4, 7/8 and travel. A dreadnought is a large body shape, a grand auditorium is a mid-size shape, and a travel guitar has a small body made for carrying. The size name tells you how the body compares with a full-size guitar.
Measure your reach before you buy
Hold the guitar in playing position and check that your fretting hand reaches the fret nearest the nut without stretching your shoulder. Your strumming arm should rest over the body without lifting your elbow high. If the body pushes your arm up or the neck feels far away, try a smaller size.
Match the size to the job
A full-size guitar suits playing at home and on stage. A travel size suits trips and tight spaces, where a full-size body gets in the way. A mini dreadnought sits in the middle: a smaller body with the dreadnought shape. Pick the size that fits where you play and how you carry it.
Check scale length and nut width
Scale length is the distance from the nut to the bridge, and a shorter scale means the frets sit closer together. Nut width sets how much room your fingers have on the fretboard. Compare the numbers the maker lists, and pick the combination that lets your fingers fret cleanly.

Frequently asked questions
What size acoustic guitar is best for a beginner?
Start with the size that lets you reach the fret nearest the nut and rest your arm over the body without stretching. A 3/4 or travel size suits a smaller frame, while a full-size guitar suits a taller player. Try both sizes before you pick one.
Is a travel guitar the same as a 3/4 guitar?
No. A travel guitar is a small guitar made for carrying, while a 3/4 guitar is a fractional size of a full-size guitar. Both are smaller than full size, but they differ in body shape and scale length, so check the size name the maker lists.
Does a smaller guitar sound different from a full-size one?
Body size changes the sound, and a smaller body gives a different voice from a large dreadnought. The wood and the build matter too, so listen to the sizes side by side before you pick one.
