The Difference Between Sizes 24 month, 2T & 2

How to Choose Between Sizes 24m 2T & 2 magical mama blog

Is my math right?

Your little bitty baby is growing up quick and is starting to outgrow their 18 month clothes….now what?

You now have the choice of 24 month, 2T and 2?

By my math, those all the same thing, right? A two year old is 2 and also 24  months?

What the heck does that T stand for?

What could the difference possibly be?

Choosing between 24 month and 2T

No two babies are alike.

I know some 12 month old babies who wear 18-24 month clothing.

There are also some one year olds who are wearing 9-12 month clothes.

Just like adults, no two babies are built the same.

24 month is cut round and usually is an expansion of the patterns for baby clothes labeled by month.  (nb, 3m, 6m, 9m, 12m, 18m 24m)

This size can be used by chunky little 12 month olds who have those baby rolls and are still crawling around.

It can also be used by skinny little 2 year old babies.

2T is cut from the patterns used in the toddler section. Hence the “T” (2T, 3T, 4T, 5T)

This size is made for walking toddlers. The T leaves room for diapers.

There may be an incredibly tall two and a half year old toddler who is working on that potty training and is wearing a size 5T to accommodate their long torso and legs, that diaper, or those chunky little cheeks.

Choosing between 2T & 2

2T, again, is cut from the Toddler section (2T, 3T, 4T, 5T).  Walking toddlers, so it’s not cut as round as the monthly sized clothes but still includes room for diapers.

2 is cut from the Children’s section patterns. (2, 3, 4, 5, 6)

Think of the children’s section as the potty trained kiddos.

Some parents have those miracle babies that are potty trained at 18 months., so they can go from 18 month clothing straight to 2.

Some of these little 2 year olds are skinny minis and the 2T’s fall off of them even if they are wearing diapers, so they need a 2.

But WAIT there’s more!

The store or brand you are shopping with doesn’t have a “2” and your kid is potty trained?

All brands and companies differ.  YAY more complications! Now you only have to choose between 24 month and 2T.

Most brands don’t start their “children’s section” until size 4.  So your options go from 24m to 2T, 3T, and 4t/4 5T/5, 6, 7 and so on.

I’m sure you noticed as your little one was going through their first year that no two brands are alike…even if the sizing guides were identical…rude.

The Carter’s 6 month was tight, the Garanimals 6 month was nice and comfy and the 6 month un-pronouncable brand you got through Wish or Amazon was huge.

All companies have their own patterns that they use to cut their fabric and no two are completely alike.

So really, you’ve already been in this situation before, you knew how old your baby was, how much they weighed and the baby section still made it confusing because of the clashing brand patterns.

Now, on top of choosing what brand to go with, you get to figure out what section to try out.

In conclusion

Think of these sizes (which seem to all be for the same baby) in 3 different sections.

Baby Section – 24 month

Toddler Section – 2T

Children Section – 2

I made a handy little general sizing guide that covers what most American brands have in their sizing charts.

    1. Fabulous! I’m glad I could be of help! Silly brands and tags make life so difficult without any explanation!
      Thank you for stopping by and checking it out!

  1. Aha, I’ve always wondered about that T! I’ve never seen this in the UK before but my mother and father-in-law go to the US every year and bring back clothes for my little ones with T in the size label. Now I know! Thanks! #triumphanttales

    1. The US loves to make things complicated! Hope this helps you and your in-laws figure out what sizes to take back to the UK for your little ones!

  2. It’s literally a minefield out there! Ben is tiny and even though he’s nearly two and a half, he’s still in 12-18 month clothes!!
    Thank you for sharing this with us at #TriumphantTales. I hope to see you back next week

    1. Why they decided to label clothes by month is silly. No two babies are alike! Babies are born all sizes and continue to differ as they grow. Maybe one day they’ll just label things by their actual measurements and we’ll be able to figure it out!
      Thanks for popping by, Lianne!

  3. When my boys were little there was 24 month and 2T and I do remember that they were different in how they fit my kids. Now they have a 3rd size though? Interesting. But you’re right, kids are all made differently. Now that my boys are older its even hard to find clothes that fit them. My tween is the hardest to shop for, especially in pants. He’s not in adult sizes yet because they’re too big but the kid sizes don’t always fit him either. Now its about which brand to buy that will actually fit him. It’s crazy! #CoolMumClub

    1. They make it so complicated! While I wish all companies would use the same patterns so we could tell what sizes would fit, the shapes that work for so many people would disappear. I guess we’re just out of luck no matter what!

    1. I wish it were simple! But, alas, all the cute clothes have to be made by difference companies who have their own version of sizing. Thank you for stopping by, Kelly!
