Youth Size Chart
In the United States, as well as in numerous other nations, youth sizing typically aligns with a child's age, height, and weight, which simplifies the daunting task of finding well-fitting clothes for youngsters. Yet, the reality of children’s growth patterns is anything but uniform; hence, it becomes crucial to take into account your child's individual measurements instead of merely depending on age as a marker.
To give you an overview, youth sizes can be categorized by age and numeric values, though for more precise information, the charts provided below will be invaluable:
Youth Size Categories:
Baby: 0 to 24 months
Toddler: 2 to 6 years
Child/Tween: 7 to 16 years
Extended Youth Sizes: Up to 20 years (in some brands)
Letter Sizes and Corresponding Numeric Sizes:
Youth XS: Size 5-6
Youth S: Size 6-7
Youth M: Size 8-10
Youth L: Size 12-14
Youth XL: Size 16-18
How to Measure Your ChildBefore we start looking at measurements and size charts make sure you are accurately measuring your child:
Height: Have your child stand barefoot against a wall with feet together. Measure from the floor to the top of their head.
Chest: Measure around the fullest part of the chest, keeping the tape measure horizontal.
Waist: Measure around the narrowest part of the waist, typically above the belly button.
Hips: Measure around the fullest part of the hips, keeping the tape horizontal.
Inseam (for pants): Measure from the top of the inner thigh down to the ankle.

Brand-Specific Size ChartsSome brands have their own youth size charts, in most instances they are very similar to the generally accepted youth sizing guidelines, but it would not hurt to double check the youth size for a specific brand as they use their own acronyms for sizing.

Tips for Shopping Youth SizesMeasure Before You Shop: Always take current measurements of your child before purchasing.
Check Brand Size Guides: Sizes can vary between brands; refer to the specific brand's size chart.
Consider Growth Spurts: If your child is in a growth phase, consider buying a size up.
Read Product Descriptions: Some items may have specific fit information (e.g., slim fit, relaxed fit).
Look for Adjustable Features: Waistbands with adjustable tabs or clothing with stretch can provide a better fit over time.
Review Return Policies: Ensure you can exchange or return items if they don't fit.
Frequently Asked QuestionsWhat are youth sizes in clothing?Youth sizes are standardized measurements that correspond to a child's age, height, and weight. They help parents and caregivers find clothing that fits appropriately to their age, height and weight.
How do youth sizes compare to adult sizes?Youth sizes are generally smaller than adult sizes. For example, a youth XL might be similar in length to an adult XS but will have a smaller waist and chest measurement. Hence, it is critical to use a youth size chart when looking for youth sizing.
Is a youth large the same as an adult small?Not exactly. While the lengths might be similar, adult sizes are cut differently to accommodate adult body proportions.
What size is a youth small?A youth small typically corresponds to sizes 6-7, suitable for children aged 6-7 years, with chest measurements between 25-27 inches.
How do I convert youth shoe sizes to women's sizes?Youth shoe sizes and women's shoe sizes can overlap. Generally, a youth size 6 corresponds to a women's size 8.
Are boys' and girls' sizes the same in youth clothing?Up to a certain age, boys' and girls' sizes are similar. However, as children grow, body proportions change, and sizing may differ.
