Is 2T The Same As 24 Months?

Is 2T The Same As 24 Months

Though 24 months is the same age as 2 years, it completely differs for kids' clothes. People often get confused between these size measurements and labelings.

The baby’s clothes' size is measured in periods such as 6 to 12 months or 12 to 18 months. A cloth size labeled as 6 to 12 months is made to fit a 6-month older baby or up to 12 months old.

If the clothes size is labeled as 24 months, it can fit a child up to 24 months old. A 2T size fits perfectly to a 2-year-old toddler. So, 2T and 24 months sizes are not the same. Below we have explained each size in a different section.

What Size Is A 24-Month-Old?

The 24 months size is made for babies aged 18 to 24 months or 2 years. The clothes in 24m size are perfect for babies weighing 28 to 30 lbs and 32 to 34” tall. The space to accommodate babies in diapers is also considered to allow easy mobility.

So, there will be extra space to make a bulky diaper fit inside the cloth to take off and on. Most clothes include stretchy bottoms, footed pajamas, and elastic waistbands.

What Size Is 2T?

This size is designed for toddlers and ideally fits an average of 2 to 3 years old. 2T size is for toddlers weighing between 29 to 31 lbs and with a height of 35 to 36.5”.

These clothes are for children who are out of diapers or have started walking. For easy understanding, here is an example:

A 4T-sized shirt will fit a 4 to 5 years old and isn’t made for 2 to 3 years old. There is the possibility of varying sizes to fit children of different ages depending on their weight and height.

The simple difference between the two is 24 months size clothes are for babies, and 2T are for toddlers. But the difference is made by looking at varying aspects such as design, style, and your child’s growth.

Size Measurement

Diaper Fit

Considering the diaper fit is a better intention to work on the idea of these sizes.

  • The 24 months size clothes have some extra room because they are intended to fit small babies wearing diapers.
  • On the other hand, 2T clothes are for toddlers or walkers who do not wear diapers and do not need extra space. They have learned over time how to pull their pants up and down.


Both clothes sizes are designed according to the age of the children.

  • The 24-month clothes are designed to be more baby-like in style.
  • In contrast, 2T clothes are not too small but are more childlike than babyish.

Easier To Take Off & On

The 24 months size clothes are specifically designed to take off and on easily. It will make it easier to change diapers and wrangle clothes. Most are rompers with onesie-style to access diapers easily.

Wrapping Up

Note that sizes are just numbers, but the clothes fittings can vary from brand to brand. It also depends on the baby's growth, who may wear clothes with a mix of both sizes. I'd highly recommend getting clothes with size up if you are in doubt. As babies grow faster, the same clothes will be useful for longer.
