Choosing the size of children’s clothes seems simple but is one of the problems that confuses many parents, especially when shopping online. Each brand and country has different size standards, so if you do not know how to choose the size according to height, weight or age, your child may wear clothes that are too tight or too loose. SmockedBede will guide you on how to choose the most standard and accurate size of children’s clothes to ensure your baby’s comfort in each outfit.
Why is it necessary to choose the correct size of children’s clothes?
Children develop quickly in each stage, in just a few months, they can gain weight, grow taller and change their shape significantly. If you choose the wrong size of children’s clothes, the consequences are not simply that the child does not fit, but also affect daily activities:
- Clothes that are too tight can easily cause discomfort, diaper rash, and hinder movement.
- Clothes that are too loose make your baby look sloppy and easily trip when running and jumping.
- Some materials can shrink when washed, causing the size to be further off if not chosen correctly from the beginning.
Therefore, determining the correct size of children’s clothing is a key factor to ensure that your baby is always comfortable, confident and safe in daily activities.
How to determine children’s clothing size according to age and height
1, Based on age – The simplest way for busy parents
Many brands divide sizes according to age. Below is a basic size chart:
| US SIZE | AGE | HEIGHT | WEIGHT | WAIST | HEAD | |
| 2-3 | XXS | 2 – 3 | 84-99 | 13.5 -16.5 | 52 – 53.5 | 51 – 52 |
| 4 | XS | 3 – 4 | 99 – 106.5 | 16.5 – 18 | 54.5 | 52 |
| 5 | S | 4 – 5 | 106.5 – 114.5 | 18 – 20 | 56 | 53.5 |
| 6 | S | 5 – 6 | 114.5 – 122 | 20 – 23.5 | 57 | 53.5 |
| 7 | M | 6 – 7 | 122 – 129.5 | 23.5 – 28 | 58.5 | 54.5 |
| 8 | M | 7 – 8 | 129.5 – 137 | 28 – 33.5 | 59.5 -61 | 54.5 |
| 10 | L | 8 – 9 | 137 – 147.5 | 33.5 -39 | 62 – 63.5 | 56 |
| 12 | L | 9 – 10 | 147 – 152.5 | 39 – 44.5 | 65 – 66 | 56 |
| 14 | XL | 10+ | 152.5 – 157.5 | 44.5 – 50 | 67.5 – 68.5 | 56 |
This is an average size. Each child may have a different growth rate, so you should combine height and weight factors.
2. Based on height – more accurate and reliable
Most children’s fashion brands today prioritize height sizes because of higher accuracy. For example:
Important notes when choosing clothing sizes for children
- Choose a little extra so that your baby can move comfortably
Do not choose a size that is too tight. For children, you should prioritize clothes that are slightly loose so that your baby can move and play easily. Some common tips are:
- Choose 1 size larger if your baby grows quickly.
- Prioritize stretchy or elastic-waisted clothes.
- Check the size chart of each brand
Each fashion brand will have its own size chart. When shopping online, you should find the specific size chart of the brand to avoid errors.
For example: Some Asian brands often have smaller sizes than European brands. But at SmockedBebe, we prefer to the US/ UK size chart.
- Prioritize materials that do not shrink when washed
Some fabrics such as cotton that have not been treated with anti-shrinkage may shrink after a few washes. Therefore, if you buy a material that is prone to shrinkage, add an extra size.
When should you re-measure your baby’s clothing size?
You should re-measure and update the size of children’s clothes every 3-6 months, especially for children under 3 years old because this is the stage when children grow the fastest. In addition, if you see that your child’s current clothes are starting to fit the belly, exposing the wrists or ankles, be ready to change to a new size. Choosing the right size of children’s clothes not only helps your child dress beautifully but also creates comfort, supports movement and physical development. Whether choosing by age or height, parents should combine both with attention to make the most suitable choice. Don’t forget to update the size regularly because each child is on a separate development journey.
