Finding the right T-shirt size for your little explorer shouldn’t feel like solving a puzzle. At Jack in the Box Clothing, we design playful, themed apparel that’s made to move, stretch, and adventure—so getting the fit just right matters. Whether you’re shopping for a weather-themed hoodie or a dinosaur tee, here’s how to measure your child and choose the best size with confidence.

📏 Why Proper Sizing Matters

A well-fitting T-shirt means:

• No tugging or twisting during playtime

• Longer wear as your child grows

• Better comfort and confidence

• A look that’s as joyful as the design itself!

✂️ How to Measure Your Child at Home

All you need is a soft measuring tape and a cooperative (or giggly) child. Here’s how:

1. Chest Measurement

• Wrap the tape around the fullest part of your child’s chest, just under the armpits.

• Make sure it’s snug but not tight—leave room for movement.

2. Height Measurement

• Have your child stand straight against a wall.

• Measure from the top of their head to the floor.

• Tip: Mark the wall with a pencil and measure from there.

3. Compare with Our Size Chart

• Match your child’s measurements to our chart above.

• If they’re between sizes, we recommend sizing up for longer wear.

🎨 Fit Meets Fun
