About Children's Clothing Sizes

Children come in all shapes and sizes, which makes purchasing clothing sometimes challenging. Figuring out the correct size for children involves knowing their length and weight, not just their age. For those wanting to buy that perfect clothing present for a growing baby, picking the perfect fit is essential for a successful gift.

Baby Clothing

Infants follow clothing sizes that follow their age in months, which also correlates with weight and length. Labels on baby clothing are marked in numbers for their age in months such as 0-3 months or 12 months. Infant clothing is labeled this way up to 24 months. Clothing for infants 0-3 months might also be labeled as newborn 2. According to Consumer Reports, there are no standard sizes in the industry, so clothing sizes vary by manufacturer.

Toddler Clothing Sizes

Toddler clothing is labeled as 2T, 3T and 4T and are based on a child’s weight and height. Most clothing manufacturers include a height and weight chart explaining their sizing 2. In general, 2T fits toddlers between 26 to 29 pounds and that average between 33 to 35 inches in height; 3T fits toddlers 30 to 34 pounds and 35 to 37 inches in height; and 4T toddlers 34 to 38 pounds and 37 to 40 inches in height.

Older Boy and Girl Clothing

Older boys' and girls' clothing has sizing labeled in numbers such as 4, 5, 6 and up. Size 4 fits children 38 to 40 pounds, 5 is fitting for children 40 to 42 pounds and size 6 for 42 to 46 pounds and so on. It is suggested to buy the clothing size one size larger when buying clothing for children that fall at the end of a size suggestion 2.

European Clothing

European clothing sizes are based on a child's height rather than age and is also in centimeters, which offers a good fit. Measurements are taken from the top of the child's head to the heel of the foot to determine the size of clothing 2. To purchase European clothing, convert the child's height from inches to centimeters to find the correct fit.


Because manufacturers can determine their own sizing for their clothing styles, weight and height suggestions can vary. Always consult the company’s sizing chart before purchasing children’s clothing to help determine the best-suggested size 2. Children grow quickly, so purchasing clothing a size larger ensures they will have a chance to wear the item for a longer period of time 2
