1/2 size guitars are very popular for young students since the age between 5 and 8 years is the perfect age to start learning guitar. The smaller size of this guitar is perfect for smaller hands. These small guitars are also very famous among travelers and backpackers thanks to the small size. However, a 1/2 guitar doesn't measure just the half of a full size guitar. Instead, it measures the half of the scale of a standard size guitar.
