What is what size is youth large?

Youth large clothing sizes vary significantly depending on the brand, the type of garment (shirt, pants, jacket, etc.), and even the country of origin. There's no single, universal standard.

However, generally speaking, a youth large will typically fit a child or young teenager around 14-16 years old. But this is just an approximation. You should always check the specific size chart provided by the brand and retailer. These charts usually list measurements like chest circumference, waist circumference, inseam, and sleeve length. Comparing these measurements to the child's own body measurements is the most reliable way to determine if a youth large will fit.
