Quick answer
For the best fit, measure your child's chest and height, then compare to the size chart. If between sizes, size up for room to grow, especially with 100% cotton tees that may shrink slightly.
Why sizing matters for toddler tees
Toddlers grow fast, and their clothes need to keep up. A tee that's too tight can be uncomfortable, while one that's too big can look sloppy or even be a tripping hazard. The right size means your child can move, play, and nap without restriction.
All Jomboy Media toddler tees are made from 100% cotton, which is soft and breathable but can shrink a bit in the wash. Pre-shrunk fabric helps, but it's still smart to account for some shrinkage, especially if you use warm water or a dryer.
How to measure your toddler
Use a soft measuring tape. For chest, measure around the fullest part, just under the arms. For height, measure from the top of the head to the floor without shoes. Compare these numbers to the size chart on the product page.
If you don't have a tape, use a string and then measure it against a ruler. Write down the numbers so you can check them against each tee's size options.
Decision rules for toddler tee sizing
- Measure first, then choose: Always measure your child's chest and height. Compare to the size chart on the product page. Do not rely on age labels alone, as toddlers vary widely.
- Size up if between sizes: If your child's measurements fall between two sizes, choose the larger size. This gives room to grow and accounts for any cotton shrinkage after washing.
- Consider the fit style: Jomboy Media toddler tees have a relaxed fit for extra comfort. If you prefer a more fitted look, stick to the child's exact chest measurement. For a looser, longer-lasting fit, size up. Check the product description for fit notes; some tees may run larger or smaller.
