Are Youth XL and Adult Small Sizes Different?

Minute Differences Mean a Lot

Even the most minute of differences can change the way a garment fits. Therefore, please consider the distinctions below before shopping for clothing. 

  • Youth XL garments fit more snuggly than adult small sizes. Because youth are typically more active in recreation, youth XL sizes give a streamlined fit for safety. 
  • Teens are shorter in their torsos than adults. A teen’s torso will continue to grow until around the age of 20. Most adult small sizes would be too long for younger teens. 
  • Youth XL sizes typically have shorter sleeves than adult small garments. The inseams generally are shorter too. 
  • Youth XL sizes have narrower waists to accommodate smaller bodies, while adult small waist lengths are larger. 

What Ages Wear Youth XL?

Youth XL shirts are intended for teens 13 to 16 years old. It is important to remember that teens, like adults, have different body measurements. Some teens can wear an adult small, while others may need a regular youth size.

How to Measure Chest Size

When deciding between youth XL and adult small, chest size is the most important measurement because it will determine which size will fit most appropriately.

You will need to measure the fullest part of the chest, which is the part that aligns with the armpits. Follow these steps.

  • Have the person stand upright with their arms resting at their sides. 
  • Make sure the person does not hold their breath during measurements. 
  • Use a fabric measuring tape wrapped around the chest, and ensure it is level with the ground and meets appropriately in the middle. 
  • Record the chest measurement. 
  • When buying sweaters, hoodies, or jackets, you should add one to two inches to this measurement.

Can You Substitute One for the Other?

You can get away with substituting an adult small for a youth XL but not with every garment. Youth clothing is designed much differently than adults’ to accommodate different body shapes. 

Children’s torsos are much boxier than adults’. Their chests often reduce in circumference as children grow because their torsos become more elongated.

A teen who wears a youth XL will likely find an adult small fits, but it may be a little baggier in the stomach area and a little tighter in the chest.

Clearing Up the Confusion

We hope this has clarified some confusion over the differences between youth XL and adult small sizes.

Unfortunately, because there are no universal sizing standards for clothing, you may need to try different brands for fit. 

 In a pinch, both sizes will work for most teens ages 13 to 16 and some smaller adults. Just remember that there will be slight differences in how the garments fit specific torso areas.

So when in doubt, always go with a slightly bigger size.
