Baby blanket size: What you need to know for your newborn

When choosing the perfect baby blanket, size matters as much as softness and warmth.

Choosing the right blanket size can provide your baby with comfort and security, warmth and insulation, a reduced startle reflex, and better sleep. However, the wrong baby blanket size can lead to discomfort, limited usefulness, and suffocation, especially for newborns.

So, what is a good baby blanket size? And what else should you look out for when buying one? Keep reading to find out more!

Types and Sizes of Baby Blankets

How big are baby blankets? The size you choose depends on the blanket’s purpose and your baby’s needs. Here are the common types and their sizes.

Swaddle blankets

A swaddling blanket is designed to snugly wrap your baby and mimic the feeling of being in the womb. It prevents startle reflexes and promotes better sleep. The average baby blanket size for a swaddle measures 40x40 to 48x48 inches and is made from soft, breathable fabrics like cotton or muslin. 

Receiving blankets

These blankets are lightweight and typically measure 18x18 inches. They are perfect for laying on the table during diaper changes, creating a soft, warm barrier between your baby and the surface. In addition, their absorbent fabric (mostly cotton) makes them great for tummy time, as a shield for burping your baby and cleaning up messes.

Some receiving blankets measure 36x36 inches, offering more versatility as your baby grows. Before buying, check the label to see how big it will be when unfolded.

Crib blankets

As the name implies, this type of blanket is perfect for keeping your baby warm and cozy in their crib at night. But what is the size of a crib blanket? They typically measure around 40x60 inches and are usually thicker and warmer than other baby blankets. With materials like fleece or cotton, they are great for cooler months or for nap time.

Multi-use blankets

Multi-use blankets are made for versatility without being too bulky. They typically measure 30x40 inches and can be used as a soft surface during playtime, or as a stroller, picnic, or car seat blanket during outings.

Stroller blanket

Stroller blankets usually measure between 40x60 inches and 50x60 inches and provide enough coverage to keep your baby warm and cozy during stroller rides, no matter the season. They are large enough to wrap around your baby even when they get bigger, protecting them from the elements.

What Size Should a Baby Blanket Be?

The size of a baby blanket is determined by your baby’s age and size, intended use, season, and personal preference.

Baby’s age and size

The American Academy of Pediatrics (AAP) recommends that babies under 1 year old should not sleep with blankets due to the risk of suffocation, strangulation, or Sudden Infant Death Syndrome (SIDS). 

Hence, only small blankets (like the receiving and swaddling blankets) are best for newborns for swaddling and cleaning up messes. 

As your baby grows (1 year and older), you will need larger blankets, such as the crib, stroller, and multi-use ones, to provide more coverage for sleep, strolls, and playtime.

Intended use

The size and type of a baby blanket go hand-in-hand with its function. For instance, swaddle blankets are large and designed specifically to wrap your baby for a snug, calming effect. 

On the other hand, receiving blankets are smaller and ideal as burp cloths, for diaper changes and tummy time. However, they do not provide the same snugness or security as a swaddle blanket.

Likewise, crib blankets are meant for use in a crib or bassinet to keep your baby warm at night. They are large and thick enough to provide warmth and comfort for your baby during nap or nighttime sleep but are too bulky for effective swaddling. 

Safety

A blanket that is too large can cover the baby's face during sleep, potentially obstructing the airway. The AAP advises alternatives like sleep sacks, swaddle blankets, or wearable blankets for babies under one-year-old. For babies over 1 year old, you can introduce other blankets, but make sure it’s lightweight, breathable, and appropriately sized for your baby to avoid it getting tangled or covering their face.

Baby Blanket Materials

When choosing the right material for a baby blanket, it's important to consider comfort, breathability, and weather suitability. Here are some popular options to explore.

• Cotton (including organic cotton): Suitable for all ages and great for warmer months or layering in cooler months. Due to its softness and breathability, it is mostly used in receiving, swaddling, and crib blankets.
• Muslin: Ideal for newborns and young infants. It’s also best for warmer weather because it is lightweight and breathable. Commonly used in swaddling and multi-use blankets because it prevents overheating.
• Fleece: Best for older infants and toddlers who need extra warmth. Perfect for colder months. It is commonly used for crib and stroller blankets, as it provides warmth without being too heavy.
• Flannel: Suitable for infants and toddlers. Best for cooler weather and ideal for crib blankets and sleep sacks because it's soft, cozy, and provides warmth.
• Bamboo: Great for all ages, especially babies with sensitive skin. Works well in moderate to warm weather due to its breathability and moisture-wicking properties. Used for swaddling, receiving, and multi-use blankets because it's hypoallergenic and soft.
• Wool: Suitable for toddlers (after 1 year) due to its weight and warmth. Best for cold weather and is used in stroller or crib blankets because of its excellent insulation.

Baby Blanket Safety

According to the American Academy of Pediatrics (AAP), it is advised that all forms of blankets (weighted blankets, loose blankets), pillows, stuffed animals, and non-fitted sheets be kept away from your baby’s sleep area until they reach 1 year of age. This is to reduce the risk of sudden infant death syndrome (SIDS), suffocation, entrapment or wedging, and strangulation.

Instead, the AAP recommends dressing your baby in light layers of clothing or using a wearable blanket or sleep sack to keep them warm.

Finding the Right Baby Blanket Size

Choosing a baby blanket is also about what will make your baby most comfortable while fitting other preferences. 

For instance, you might prefer muslin swaddling blankets for their lightweight and breathable nature. Another parent might lean towards 100% cotton or organic cotton blankets because of their softness and gentleness on the baby’s skin. 

You could also choose neutral tones or soft pastels to complement the nursery décor or go for vibrant patterns and prints that express personality and joy. If you’re looking for versatility, multi-use blankets offer convenience, practicality, and comfort without sacrificing style.
