How to find the right size
Every child is different – so one pattern size doesn't always fit perfectly. Our calculator shows you which size your child needs and whether you should adjust your pattern. Choose your pattern and we'll show you step by step how to do it – whether you work with paper or a projector.
Ba.binaa kids' size chart
Our standard body measurements. Some older patterns have their own size chart – the calculator takes it into account automatically.

Frequently asked questions
Which sewing pattern size does my child need?
Ba.binaa kids' sizes are based on height: size 110 fits children from 105 to 110 cm (41 1/4–43 1/4"). The width is chosen by chest circumference for tops and by hip circumference for pants and skirts. Enter the measurements above and the calculator shows the right size for every pattern.
How do I measure my child correctly?
Height: without shoes, back against the wall, heels together. Chest: horizontally around the fullest part of the chest, under the arms. Hip: horizontally around the fullest part of bottom and hips. Keep the tape snug but do not pull.
What if length and width are different sizes?
Trace the pattern in the width size and lengthen or shorten it to the length size: with a paper pattern by cutting and spreading at waist and hip, with a projector by moving the fabric. Our step-by-step guide shows both methods. This works well up to about three sizes difference.
How do European kids' sizes convert to US sizes?
As a rough guide: 86 ≈ 18M, 92 ≈ 2Y, 98 ≈ 3Y, 104 ≈ 4Y, 110 ≈ 5Y, 116 ≈ 6Y, 122 ≈ 7Y, 128 ≈ 8Y, 134 ≈ 9Y, 140 ≈ 10Y. Always measure your child – the body measurements are more reliable than the age.
Can I enter the measurements in inches?
Yes. Switch the unit to "inch" – the calculator converts everything and also shows the fabric requirements in yards and inches.
