Sizing & Fit Hub
At DENNIS, we know that sizing and fit are critical. With the information below, we're here to help you get the right size for your child and take the guesswork out of uniform shopping.

How to Accurately Measure Your Child
- Height: stand tall (without shoes) and measure from top of head to floor.
- Chest: measure at the fullest part in inches.
- Waist: measure at the narrowest part in inches.
- Weight: in pounds.
Record these numbers using a standard measuring tape, then use our size charts (below) to find the best size! Between sizes? Order a size up to ensure the best, longest-lasting fit.
