For boys, you should always ensure there’s enough room in the crotch area. Restrictive clothing in that area can not only make your boy uncomfortable but can also lead to complications over time. So when you fit pants, add an inch if you feel it’s necessary.

How to Measure a Kid’s Pant Size

Children’s apparel sizes are usually specified according to age. However, if you want to find the perfect fit, it’s much better to use your child’s height, weight, hip, waist, and inseam measurements.

Let your child wear skin-tight pants or only underwear — there should be as little padding as possible for an accurate reading. Using a cloth measuring tape, here’s what you do:

• Hips: Begin by measuring your child’s hips — ensure you place the measuring tape around the fullest part.
• Waist: Measure the waist by going around the lower belly, near the belly button.
• Inseam: Measure from the center of the crotch, on the inside of the leg, down to the foot.
• Height: Let your child stand against a wall, with the feet aligned and back straight. Then measure their height from the top of the head to the floor.

Once you’ve got the measurements, match them with the clothing brand you’re buying.

Tips for Buying Pants/Bottoms

To prevent as many frustrations as possible, we’ve gathered some additional tips for buying pants/bottoms for the above age groups. Let’s start with babies:

Tips for Babies

When buying pants or bottoms for babies, there are a few considerations to keep in mind. Avoid buying in bulk for your newborn. Babies grow fast within the first weeks and months, so they will probably change sizes pretty quickly ⁽¹⁾.

• Buy larger: Babies can easily rock pants that are a size or two bigger. Your little one will likely soon enter a growth spurt, and the bottoms will fit just right.
• Ensure it’s simple: You must consider how easy the pants are to put on and off for diaper changes. Buttons and tiny zippers aren’t ideal when changing a wiggly baby.
• Go for soft and stretchy: For babies, soft, stretchy materials are best. This ensures optimal comfort as well as easy changing.
• Opt for elastics: Look for an elastic waistband, even on jeans. Non-elastics may appear cute, but the chances are that they’re uncomfortable for your baby.

Tips for Toddlers

As a toddler, your little one suddenly becomes much more independent. Here are some tips:

• Easy to pull on and off: Opt for pants that are easy to pull on and off. This way, tots can do it themselves if they prefer.
• Consider the diaper: Not all toddlers have mastered the art of toilet training yet. If so, consider how much room the diaper takes up and ensure you can close the zipper with one on. My little one went down a pant size once the diaper was off.
• Opt for comfort: It’s best to stick with soft, stretchy materials.
• Involve your toddler: If you can, bring your toddler along with you when shopping. Pick out two or three pairs and let them choose. You might even get them into the fitting room to try them on.
• Look for sturdiness: Toddler pants need to be of durable material because of how active the wearers are.

Tips for Older Kids

Once your child is out of the toddler years, it generally becomes easier to involve them in the process. Here are some tips:

• Bring your child: If you can, bring your child with you to the shop. Perhaps let them pick out what they like and have them try it in the fitting room if possible. This way, you’re sure it’s the right fit.
• Buy one size up: Your child is likely to experience growth spurts until age 14 for girls and 16 for boys ⁽²⁾. Hence, we recommend buying one size up to avoid having to buy new pants too often. You can always buy a belt for them until the pants fit correctly.
• Bring a pair of pants: If you’re doing the shopping alone, bring a pair of pants that fit your child. Then use them as a guide for the new ones.
• Keep measurements with you: You can keep them on your phone or a small piece of paper in your wallet or purse. Make sure to update them as your child grows.
• Stick to the same brands: Sizes vary between brands. If you have a favorite brand, use them for as long as possible to make it a bit easier for yourself.
