The 3/4 size is smaller, so check the size name before you buy. This guide explains what 4/4 means, how to check the fit, and what comes in the bundles.
What full size means on a guitar
Full size is the name for a 4/4 guitar. The sizes run 4/4, 3/4, 1/2 and 1/4, and the number names the size of the guitar, not a model or a brand. A 3/4 guitar is smaller than a 4/4 guitar, with a shorter body and a shorter scale. Read the size in the product name and specs before you buy, since dreadnoughts can be different sizes.
Check the fit before you buy
Sit down with the guitar and rest its body on your leg. Your fretting arm should reach around the neck to the far frets without stretching, and your strumming arm should rest over the body without lifting your shoulder. If the body feels too wide to reach around, or the neck feels too long to reach the far frets, look at a 3/4 size instead. The fit matters more than the size name on the label.
What comes in the bundles
Some guitars come on their own, and some come in a bundle with the parts a beginner needs to start. The Donner bundle includes a padded gig bag, strap, digital clip-on tuner, capo, extra steel strings, 4 celluloid picks and a cloth. The Fender bundle includes a gig bag, strap, extra strings, picks and an instructional video. A clip-on tuner reads the pitch of each string so you can tune to standard tuning E A D G B E. Check what each bundle includes before you buy, since the parts differ from bundle to bundle.
Keep the guitar clean and in tune
Wipe the guitar with a soft dry cloth after you play, and keep it out of damp rooms and direct sun. Use warm water and mild soap where the instrument allows it, or the maker's own cleaner, and dry the surface after. If the strings look discolored or rough, show rust, or no longer hold tune, change them. For anything inside the guitar, such as truss rod work or fret leveling, ask a repair shop.
