Onesie Sizing Guide
It is difficult to know the size of your baby or how quickly they will grow after they are born. The following is a general guide to baby sizes, but it is important to keep in mind that sizes can vary between manufacturers and products.
- Newborn: Typically fits babies weighing up to 7 pounds. If your ultrasound indicates that your baby is large, you may want to skip this size.
- 0-3 months: Fits babies weighing 7-12 pounds and measuring up to 23 inches. Some babies may skip this size.
- 3-6 months: Fits babies weighing 12-17 pounds and measuring up to 27 inches.
- 6-12 months: Fits babies weighing 17-22 pounds and measuring up to 29 inches.
- 12-18 months: Fits babies weighing 22-27 pounds and measuring up to 31 inches.
If you want to purchase newborn sizes before your baby arrives, it is recommended to buy only three or four pieces. Size 3-6 months is the best size to have on hand before the birth. Once your baby is born, you can assess their size and determine when to purchase larger sizes.

How To Choose The Right Onesies?
When you are preparing to buy a onesie for your baby, keep the following things in mind.
Cotton oneies are a good option because they don’t cause allergies. Less reactive materials are preferable to cotton and polyester blends for dressing a newborn. Another excellent choice is organic cotton, which is manufactured without using any harsh chemicals and is environmentally friendly.
Choose a onesie that won’t limit your baby’s movement or make them uncomfortable. To find out this, think about looking at the features and reviews.
To ensure that it fits your infant properly, choose a size higher. The sizing charts should be read because they may vary from brand to brand. Understanding the size of your baby can be made easier for you if you read the reviews and the question and answer section.
To make it simple to pull over your baby’s head and shoulders, think about items with expanding or lap shoulders. Additionally, take into account snaps along the bottom for simple diaper changing. Depending on the weather, you might prefer wearing long sleeves or short sleeves. Choosing the perfect onesie for your child also involves considering the vibrant patterns and creative designs.
Make sure the onesies don’t need any extra washing by reading the features. It is best to purchase things that are quick and simple to wash and use mild detergents.
What’s the Best Material for Baby Onesies?
When it comes to selecting onesies for your baby, it’s important to choose a material that is suitable for the climate and gentle on your baby’s sensitive skin. Our top recommendation is cotton, as it effectively wicks away moisture and is less likely to irritate your baby’s skin.
In case you are unable to find pure cotton, a blend that contains polyester, spandex, or bamboo is a good alternative. These materials are also breathable and easier to maintain.
How Many Onesies Do I Need?
Babies are known to spit up, have sudden diaper leaks, and make a mess while eating, so it’s a good idea to have a sufficient number of onesies on hand. We suggest starting with a minimum of four to seven pieces. However, if you want to limit your laundry loads or if your baby is particularly messy, you may want to increase that number to accommodate the extra clean-ups.
How to Wash Baby Onesies?
Before making a purchase, it is important to carefully read the label. This will help you to determine if the onesies have any special washing instructions.
When your baby needs a change, you want to have clean clothes readily available. To save time, it is recommended to wash the onesies with a mild, fragrance-free detergent in the same way you would sort your laundry by color. This will make it easier to care for your newborn and keep up with the laundry.
