A 1/2 size guitar case is a case built to fit a 1/2 size guitar, which is smaller than a full-size guitar. The case matches the smaller body and shorter length, so check the guitar's measurements against the interior dimensions the case lists before you buy.
What 1/2 size means
Guitar sizes use names such as 4/4, 3/4, 1/2 and 1/4, and 1/2 is the name for a smaller guitar than a full-size one. A 1/2 size case is built around that smaller guitar, with a shorter length and narrower bouts than a case for a full-size guitar. A full-size guitar will not fit in a 1/2 size case, so match the case size name to the guitar size name.
Measure the guitar before you buy
Measure the guitar from the end of the body to the tip of the headstock for the overall length, then measure the body length and the upper and lower bout widths. Compare each figure with the interior dimensions the case lists. The Gator gig bag lists an overall length of 40.3 inches, a body length of 20 inches, a lower bout width of 14.9 inches and an upper bout width of 12.7 inches, so a guitar larger than those figures will not fit.
Check the padding and the neck strap
Look for padding through the whole bag, since the padding guards the guitar against nicks and scratches in daily carrying. The CAHAYA bag has 6mm padding throughout, and the Gator gig bag has 10mm internal padding. Check for a neck strap as well, since the strap holds the guitar in place inside the bag.
Check the straps, handles and pocket
A case with adjustable backpack straps and grip handles gives more than one way to carry the guitar. The CAHAYA bags have a large front pocket that holds music sheets, a tablet, a tuner, strings and cables, so the small items travel with the guitar. Check the zipper and the rubber base before you buy.
Try the guitar in the case
Put the guitar in the case and fasten the neck strap so the guitar sits still. Close the zipper and check that the headstock has room and the body sits flat against the padding. Lift the case by the straps and the handles to check the carry before you leave.

Frequently asked questions
Will a full-size guitar fit in a 1/2 size case?
No. A 1/2 size case is built for a 1/2 size guitar, which is smaller than a full-size guitar. A full-size guitar is longer and wider than the case, so it will not fit inside.
How do I know a case fits my guitar?
Measure the guitar's overall length, body length and bout widths, then compare each figure with the interior dimensions the case lists. The case fits when every figure is smaller than the matching interior dimension.
What padding should a guitar case have?
Look for padding through the whole bag, such as the 6mm padding in the CAHAYA bag or the 10mm internal padding in the Gator gig bag. The padding guards the guitar against nicks and scratches in daily carrying.
Do these gig bags fit a bass guitar?
No. The CAHAYA bags state that they are too short for an electric bass guitar, and they fit 40-inch electric guitars. Choose a bass guitar bag when the guitar is a bass.
