Sizing Guide for Youth Shirts

A youth small is not a universal age or body size. For the Gildan 5000B and 2000B models below, size S measures 17 inches across the shirt laid flat and 22 inches in body length. Compare those dimensions with a shirt that already fits well.

How to measure a well-fitting shirt

1. Choose a shirt with the fit you want, preferably one that has already been washed. Lay it on a flat surface and smooth it without stretching.
2. Measure straight across the chest just below the sleeves. This is flat garment width, not the measurement around a person's chest.
3. Measure from the high point of the shoulder beside the collar down to the bottom hem. Keep the tape straight. Check the model's specification for the exact measuring point.
4. Compare both width and length with the same garment model in the chart. Write down the model as well as the size when collecting a group order.

Youth XL vs. adult small

In Gildan's cited chart, youth XL is 20 inches wide and 26.5 inches long; adult 5000 small is 18 inches wide and 28 inches long. Youth XL is therefore 2 inches wider and 1.5 inches shorter. Adult small is not simply the next size up. Use the comparison above to see the difference in either inches or centimeters.

Are Gildan 5000B and 2000B the same size?

The 2026 manufacturer guide lists the same nominal width and length for these two youth models. They remain different products, and matching chart dimensions do not guarantee identical feel or fit. These charts do not apply to every youth style in our catalog.

Choosing sizes for a team or school

Share the exact model's chart with families. Avoid assigning sizes from ages, grades, or a generic dress-size conversion. If fit is important or two sizes are close, checking a sample garment can help resolve uncertainty. The measurements here come from published specifications, not staff wear tests.

For a mixed youth and adult order, use the adult Gildan sizing guide. Prepare a print that suits the smallest garment using our artwork scaling guide, then compare ways to keep a group shirt order affordable.
