Find the right fit

DENNIS provides size charts specific to certain categories of products, available on product selection pages in your school’s web store. The charts are designed to provide you with a general idea of how DENNIS products will fit your child.

 

How do I measure?

  • ➊ Start with your child’s height — shoes off, from floor to top of head.
  • ➋ Measure your child’s chest — the fullest part.
  • ➌ Measure your child’s waist at the natural waistline — the narrowest part (not where the garment’s waistband sits).
