Quick answer

For the best fit, measure your child’s chest and height, then compare to the brand’s size chart. Jomboy Media youth tees run true to size, but if your child is between sizes, size up for room to grow. Avoid guessing by age alone—kids grow at different rates.

How to measure your child for a youth tee

Start with two key measurements: chest circumference and height. For chest, wrap a soft tape measure under the arms and across the fullest part of the chest, keeping it snug but not tight. For height, have your child stand straight against a wall and mark the top of their head. Use these numbers, not their age, to find the right size on the brand’s size chart.

Comparing youth tee sizes across brands

Youth tee sizes vary between brands, so always check the specific size chart for the shirt you’re buying. Jomboy Media youth tees are designed for a standard fit that matches most US youth size charts. If your child wears a size 8 in one brand, they may need a size 10 in another—measurements are more reliable than labels.

When to size up or down

If your child’s measurements fall between two sizes, consider how they like their fit. For a relaxed, longer-lasting fit, choose the larger size. For a trim, more fitted look, go with the smaller size. Keep in mind that cotton tees may shrink slightly after the first wash, so sizing up can help maintain the fit over time.

Decision rules for youth tee sizing

  • Measure chest and height: Use a soft tape measure for chest and a wall for height. Write down both numbers before looking at size charts. Avoid relying on age alone—measurements are more accurate.
  • Consult the brand’s size chart: Each brand has its own sizing. Compare your child’s measurements to the specific chart for the youth tee you want. Check the chart every time you buy a new brand.
  • Account for growth and shrinkage: If between sizes, size up for room to grow. Pre-shrunk fabrics shrink less, but cotton can still tighten after washing. Size up if you want the tee to last more than one season.
