Konny's Size Guide

Why is it so hard
to pick the right size
for my child?

First, every brand uses different
sizing system.
Some go by age,
others by height, and sometimes
the standards aren’t very clear.

With standards all over the place,
it’s only natural you’d feel a bit lost.

  • BRAND A

    SIZE 3, 5, 7, 9...

  • BRAND B

    1-2Y, 3-4Y, 5-6Y...

  • BRAND C

    80, 90, 100, 110...

Meanwhile, kids grow at their own pace
and have different body types,
even at the same age.

While it’s more accurate to use height
and weight over age, some kids are
naturally slimmer or chubbier.

Now at Konny,
simply choose
by height

“My baby wears a size 80
in another brand. Should I buy
the 1-2Y(80) size at Konny too?”

We heard this question a lot.
So we simplified our sizing into
one clear standard.

This system is more commonly
used by global brands,
making size selection easier.

What Do Our Sizes Mean?

Optimal for children 70~80 cm tall.

The Konny Fit Test

A size 80 item on an 80 cm child
will most clearly show the product’s
intended fit (slim fit, regular fit, overfit).
On a 70~75 cm child, it will
be roomier but still fit well.

Choose the Right Size
Every Time

Check the standard size guide
on every product page and select the
best size based on your child’s height.

slimmer side, it maybe a good idea
to purchase one size down.

FAQ

  • My kid wears a size 90 in other brands. Does that mean I should buy a size 90 at Konny too?

    Every brand has different sizing standards, even if the sizes appear identical in number. At Konny, a size 90 means it is optimal for a child who is 90 cm tall. However, another brand’s size 90 may have been made for an 85 cm child. We recommend that you refer to our standard size guide, the actual measurements for each product, and the model shots to make the most informed decision.

  • My child usually wears a size 100, but I’d like to know if Konny’s clothes tend to be more relaxed fit or slim fit.

    We believe children’s clothes should be comfortable first and foremost, so we tend to make our items more relaxed fit. However, the fit can vary depending on the category or item. Our leggings are slim fit, while our t-shirts come in both regular fit and overfit. Unless your child is especially skinny or chubby, a Konny size 100 will fit a child 90-100 cm tall very well.

  • Is last year’s size 100 the same as this year’s size 100?

    All our sizes are now a bit roomier. Our new size 100 has been designed to fit a 100 cm child perfectly, so you may notice that items are a bit longer or roomier than last year’s 3-4Y (100) size.

  • My child has grown out of the Newborn 24M size, so I’d like to move onto the Baby sizes. What do you recommend as a next step?

    As we switched from an age-based system to a height-based system, we got rid of the Baby sizes category as well. According to our old sizing system, the 24M size was optimal for 80-85 cm children. Now, if your child is taller than 85 cm, we recommend size 90 or higher. Please refer to our standard size guide and the product’s actual measurements before purchase.
