Your kid has outgrown youth large, the next size up is youth XL, and after that comes adult small. But is youth XL vs adult small really a step up, or are they the same shirt with different labels? It’s a common question for parents, coaches and anyone ordering team shirts, and the answer is a little more interesting than “yes” or “no”.
In this guide, we’ll compare the official charts, explain when to switch to adult sizes, and cover what to do when a child needs something bigger than youth XL.
Youth XL vs Adult Small: The Short Answer
They overlap at the chest, but they aren’t the same. A youth XL is cut for a growing body, so it’s shorter and a bit wider for its length. An adult small, on the other hand, is longer in the body and sleeves and narrower through the shoulders. As a result, a teen can fit both at the chest but still find one much more comfortable.
Youth XL vs Adult Small Chart
The numbers below come from Nike’s official kids’ clothing size chart and men’s tops chart. They are body measurements in inches.
| Size | Numeric | Approx. age | Height (in) | Chest (in) |
|---|---|---|---|---|
| Youth L | 14 – 16 | 12 – 13 | 58 – 62 | 30 – 33 |
| Youth XL | 18 – 20 | 13 – 15 | 62 – 67 | 33 – 36 |
| Youth XL Plus | 18 – 20 Plus | 13 – 15 | 63 – 67 | 37 – 40 |
| Adult XS | — | — | — | 31.5 – 35 |
| Adult S | — | — | — | 35 – 37.5 |
| Adult M | — | — | — | 37.5 – 41 |
Notice that Nike’s youth XL chest range of 33 to 36 inches overlaps with both adult XS and adult small. In other words, the chest alone won’t decide it. Height and body length matter just as much.
Why Length Makes the Difference
Garment measurements tell the rest of the story. According to this youth XL measurement guide, a Gildan youth XL measures about 20 inches across the chest and 26.5 inches long when laid flat. Meanwhile, a Gildan adult small is about 18 inches across but roughly 28 inches long.
So the youth shirt is actually wider, while the adult shirt is longer. That’s why a tall, slim teenager often looks better in an adult small, whereas a shorter, stockier child is usually more comfortable in youth XL.
When Should a Child Move to Adult Sizes?
There’s no single age, but these signs usually mean it’s time:
- Height: Nike’s youth XL tops out at 67 inches (5’7″). Beyond that, adult sizes generally fit better.
- Length: if youth XL shirts end above the belt or ride up when they raise their arms, the body is too short.
- Sleeves: long sleeves stopping well above the wrist are another clear sign.
- Shoulders: if the shoulder seam sits on the upper arm instead of at the shoulder, try adult small.
Is There a Youth XXL?
Usually not. Most major brands, including Nike and Gildan, stop their youth range at XL (18–20). Instead of a youth XXL, some brands offer “Plus” versions. For example, Nike’s youth XL Plus fits a 37 to 40 inch chest, which is wider than an adult small.
Therefore, if a child has outgrown youth XL in width but not in height, look for youth Plus sizes first. If they’ve outgrown it in both, move to adult sizes. Our XS to XXL size chart shows where adult sizes go from there.
Tips for Ordering Team or School Shirts
- First, ask for chest and height rather than age, because kids of the same age vary a lot.
- Next, order samples of youth XL and adult small if you can, since brands differ.
- Then remember that adult shirts are longer, so they can look baggy on younger kids.
- Finally, round up for kids who are growing fast. A season later, the bigger size usually fits well.
Quick Answers
Is youth XL the same as adult small?
Not exactly. The chest sizes overlap, but adult small is longer and cut for adult proportions.
What age is youth XL?
Nike lists youth XL for roughly ages 13 to 15. Still, height and build matter more than age.
What is bigger than youth XL?
Usually youth XL Plus, or adult small. Very few brands make a true youth XXL.
Choosing Between Youth XL and Adult Small
To sum up the youth XL vs adult small question, think “wider and shorter” for youth XL and “narrower and longer” for adult small. Measure chest and height, compare them with the brand’s chart, and then pick the cut that matches your child’s shape. If they need more width, look for youth Plus sizes. If they need more length, it’s time for adult sizes.
