Electric guitar sizes run from full size, written 4/4, down through 3/4, 1/2 and 1/4 sizes. Full size is the standard size, and the smaller sizes have shorter necks and bodies for players with a shorter reach. The Donner DST-152R, the Pyle EG Fire and the Donner DSC-128 are full size, and the CAHAYA set measures 39 inches.
What full size means
Full size, written 4/4, is the standard electric guitar size. The Donner DST-152R is listed as full size, the Pyle EG Fire is a full size instrument, and the Donner DSC-128 is a full size solid body. The CAHAYA set measures 39 inches, the same length as the Pyle and the Donner DSC-128.
Smaller sizes: 3/4, 1/2 and 1/4
The smaller sizes are fractions of full size: 3/4, 1/2 and 1/4. A smaller size has a shorter neck and a smaller body, so the frets sit closer together and the player reaches less far across the neck. Measure the player's arm and hand span against the size, and try the size in person where you can.
Count the frets and pickups
Fret count and pickup layout change what the guitar offers, so check both. The Donner DST-152R has 22 frets and an HSS pickup layout with a coil split function and a 5-way pickup switch that creates 7 modes. The Pyle EG Fire has a 21-fret neck with dual humbuckers and a 3-way switch. The CAHAYA set has an HSS layout with 1 humbucker and 2 single-coil pickups and a 5-way pickup switch. The Donner DSC-128 has dual humbuckers, listed as H-H pickups.
