The perfect fit for your little one

Choosing the right size for your baby can feel tricky, because babies grow fast and every little one is different. Our baby clothing size guide helps you compare age, height (in inches), and weight so you can pick the best fit with confidence.

Quick tip: If your baby is between two sizes, we usually suggest choosing the larger size so there is room to grow.

📏Measure First

Check your baby's latest height and weight.

🧸Comfort Matters

Choose a fit that allows comfortable movement.

💗Room to Grow

Choose the larger size if measurements fall between sizes.

Size tip: Sizes are a general guide. Please select the size that best matches your baby's height and weight, not just age.

How to Use the Size Chart

Finding the right size takes just a minute.

  • 1Measure your baby's height in inches and note their latest weight.
  • 2Find the row where the height and weight both fit.
  • 3If the two point to different sizes, or your baby is close to the top of a range, choose the larger size.
  • 4Use age only as a rough guide to double-check your choice.

How to Measure Your Baby

For the best fit, measure your baby gently and compare the numbers with the chart above.

📏

Height

Lay your baby flat on their back and measure from the top of the head to the heels.

🧸

Chest

Measure around the fullest part of the chest, just under the arms.

🎀

Waist

Measure around the natural waistline, just above the belly button.

⚖️

Weight

Use your most recent weight from a home scale or a checkup.

Tip: Measure over a thin layer of clothing or a diaper, and keep the tape snug but not tight. A second person can help keep your baby still.

Which Size Should I Choose?

Every baby grows at their own pace. Use these simple guidelines when choosing an outfit.

What size is best for a newborn?

Newborn and 0-3M sizes suit most babies in their first weeks. If your baby is expected to be larger, 0-3M may be the better starting point.

What if my baby is between two sizes?

Choose the larger size. Babies grow quickly, and a little extra room is more comfortable and lasts longer.

Should I go by age or by weight and height?

Go by height and weight first. Age is only a guide, because babies grow at different speeds.

How much room should I leave for growth?

A little extra room is helpful, but clothes should not be so loose that they affect comfort or movement.
