How to measure your child properly

Height
Measure your child standing against a wall, without shoes, from the floor to the top of the head.
Weight
Weigh your child in light clothing for a more accurate result.
Between two sizes?
Always choose the larger size. Children grow fast and will be more comfortable.
Head circumference
Measure above the ears and eyebrows with a soft tape. Winter beanies stretch ±2 cm, but sun hats require a precise fit.

Find the right clothing size for your child in 30 seconds

Finding the right clothing size for a fast-growing child can be tricky, especially with second-hand items where labels may be faded. Our free calculator gives you the exact size based on your child's age, weight, and measurements. It covers baby sizes (0-24 months), toddler sizes (2T-4T), and kids' sizes (4-12), with equivalences between Canadian, American, and European sizing systems.

Sizing tips for second-hand children's clothing

Shrinkage is already done
Pre-worn and washed clothes have generally reached their maximum shrinkage. 100% cotton shrinks 3-5%, cotton/polyester blends 1-3%, and pure polyester less than 1%. The size you see is the real size.
Sizing varies by brand
Generous fit: Carter's, OshKosh, Old Navy. Standard fit: Souris Mini, Petit Bateau, Deux par Deux. Slim fit: Zara Kids, H&M, Gap. When in doubt, our team can verify measurements before your purchase.
Label ≠ real size
In second-hand, the label only tells part of the story. That's why actual measurements and our calculator are your best allies. At Picoti-Picota, we inspect every item to guide you to the right fit.

Frequently asked questions about children's sizes

What size clothing for a 6-month-old baby?

A 6-month-old baby typically wears 6-9M (EU size 74). This corresponds to a height of 67 to 72 cm and a weight of 7.7 to 9.5 kg. If your baby is tall for their age, go one size up (9-12M). Use our calculator above for a personalized result.

How to convert European sizes to Canadian sizes?

European (EU) sizes are based on the child's height in centimeters. Here are the most common equivalences:

  • EU 56 = NB (newborn)
  • EU 62 = 0-3M
  • EU 68 = 3-6M
  • EU 74 = 6-12M
  • EU 80 = 12-18M
  • EU 86 = 2T
  • EU 92 = 3T
  • EU 104 = 4T/4

See our complete conversion chart above for all sizes.

My child is between two sizes, what should I do?

Always choose the larger size. Children grow fast and will be more comfortable in slightly bigger clothing. This is especially true for second-hand clothes that cannot be returned.

What size hat or beanie for my child?

Hat size depends on your child's head circumference. Measure above the ears and eyebrows with a soft tape. Guidelines by age:

  • 0-12 months: 44-46 cm (size XS)
  • 1-2 years: 46-50 cm (size S)
  • 2-4 years: 50-52 cm (size M)
  • 4-6 years: 52-54 cm (size L)

Winter beanies are stretchy — the same size often fits. For sun hats, prefer a precise fit.

Are sizes the same in Canada and the United States?

Yes, Canada and the United States use the same North American sizing system for children's clothing: NB, 0-3M, 3-6M, 6-9M, 9-12M, 12M, 18M, 24M for babies, then 2T to 5T for toddlers, and 4 to 12 for older kids.
