Choosing the correct clothes sizes for your children is one of the most exhausting tasks for most parents because there is no standard children’s clothes size guide.
Most children’s clothes brands size their clothes by age in months, but they don’t keep in mind that children come in different heights, weights, and shapes, so there will be chances your baby will not perfectly match his or her age. Now that you know children’s height and sizes may vary, our children’s clothes size guide will help you choose the correct size.

Baby clothes size guide
Baby clothes range from preemie to 24 months. This 24 months or two years you will go through many sizes of baby clothing.
How do you know what size baby clothes to buy?
Choose your baby’s clothes using height and weight, not according to age. I know most brands are labeled with a range fit, such as NB for newborns, 0-3 months, 3-6 months, 6-9 months, 9-12 months, 12-18 months, and 18-24 months. Others are labeled with a specific month, like 3 months, 6, 9, and 12. The specific month means the maximum age your child can fit into that cloth. Don’t rely on such age range fits unless they are working well with your baby.
If the brand label does not have the measurement in height and weight check their website before you buy to achieve an accurate fit.
Baby clothes size guide
|Age||Height (inches)||Europe height (cm)||Weight||US size|
|Newborn||17-21||43.2-53.3 cm||5-8 lbs/ 2.3-3.6 kg||–|
|0-3 months||21-24||53.3-61 cm||8-12 lbs/3.6-5.4 kg||Newborn, 0-3 M|
|3-6 months||24-26||61-66 cm||12-16 lbs/ 5.4-7.3 kg||3-6 M|
|6-9 months||26-28||66-71.1 cm||16-20 lbs/ 7.3/9.1 kg||6-9 M|
|9-12 months||28-30||71.1-76.2 cm||20-24 lbs/9.1-10.9 kg||9-12 M|
|12-18 Months||30-32||76.2-81.3 cm||24-28 lbs/10.9-12.7 kg||12-18 M|
|18-24 Months||32-34||81.3-86.4 cm||28-32 lbs/12.7-14.5 kg||18-24 M|
Toddler clothes size guide
Toddler clothes range from 2 years old to 4 years old. The clothes are labeled with the letter T (like 2T, 3T, 3T, and 4T), and the others with just numbers (like 2, 3, and 4).
The T stands for toddler, and the number before it is an approximate age. 2 and 2T are not the same age. T-sizes are slim, an inch shorter, and have room for a diaper. The T size is for the toddler who is still using the diaper. You will notice they have snaps between their legs for an easy diaper change.
The size without a T (2) is ideal for toddlers who are not using diapers because they mimic adult clothes in a smaller size.
In the same case with baby clothes, you choose the toddler’s height and weight.

|2 t||28-32 lbs/12.7-14.5 kg||32-34||81.3-86.4|
