Baby blankets measure 14 by 16 inches. They’re usually crocheted by hand as a keepsake or security blanket for toddlers and infants.


Cradle blankets are 14 by 30 inches and are for infants while they’re in their cradle.


A premie blanket is 18 by 24 inches. The blankets are for Neonatal Intensive Care Unit (NICU) babies, as the name suggests. Premie blankets are small enough to swaddle premature babies until they’re old enough to leave the NICU.


The stroller blanket measures roughly 22-30 by 30-36 inches. The blanket fits over a baby when they’re in their stroller or sitting on a car seat, similar to a throw blanket or lapghan for adults.


A lapghan is a crocheted blanket and measures 36 by 48 inches. The lapghan is also known as a lap-size Afghan, wheelchair blanket, and hospice lap blanket. Lots of hospitals, nursing homes, and assisted living homes take handmade lapghan donations for their patients to use, primarily if they are bedridden or wheelchair-bound.


Receiving blankets are mainly used for infants and measure 40 by 40 inches They’re often thin, soft blankets and typically sold in packs. They’re smaller than the typical swaddling blanket, but still big enough for swaddling and also work as a burp cloth, tummy time blanket, and a changing mat.


Crib blankets measure 45 by 60 inches and fit in most cribs and toddler beds. The blankets are also big enough to work for swaddling your infant or as a changing station if you’re ever in a pinch.


Throw blankets are decorative blankets measuring 50 by 60 inches. You can drape them over your sofa or the edge of your bed for a pop of flair, or place them over your lap when watching a movie. However, throw blankets aren’t big enough to cover your entire body during sleep.


Afghan blankets can vary in size, though they’re most commonly about 50 by 65 inches. Afghan blankets are named after their place of origin, Afghanistan, where natives crochet vibrant and decorative blankets and rugs out of karakul wool. Afghan blankets aren’t only beautiful, but they also make for cozy blankets and unique throws.

Blankets for Standard Size Mattresses

Many blankets are designed to specifically hang over one of the standard mattress sizes. The exact size of the blanket may vary, although they are usually at least a few inches wider and longer than the matching bed size.


Twin blankets measure 65 by 90 inches. The blankets are long enough to fit easily on both twin beds and twin XL mattresses.


Double blankets are 85 by 90 inches and, just as their title suggests, they work on full (double) mattresses.


Queen blankets measure 90 by 90-100 inches. They fit best on a queen mattress, but you can get away with using queen blankets on a thick full bed or a thin king bed if needed.


King size blankets are the biggest sizes, measuring 108 by 90-100 inches. They fit a standard king and California (Western) king size bed best. If dressing a California king mattress, look for a king size blanket on the longer end because California kings are four inches longer than your standard king bed.

Frequently Asked Questions

What’s the best type of blanket to sleep with?

Choose a blanket size to match your mattress so you’re fully covered at night and don’t need to worry about getting cold.

Regarding a blanket’s materials, this depends on what you want from your blanket. The most common types of blankets are cotton, wool, vellux, down, fleece, synthetic, and electric. Here’s a quick rundown of each:

  • Cotton: Cotton is soft, durable, and machine-washable. It comes in a variety of quality levels and feels, so you can choose between heavy and warm or lightweight and cool cotton.
  • Wool: Wool is a very cozy and heavy material great for winter months. Since wool comes from sheep, this material isn’t an option for vegan and plant-based shoppers.
  • Vellux: Vellux, also known as hotel blankets, contain a thin layer of foam wrapped in a soft nylon casing. The blanket is so popular in hotels because it’s hypoallergenic and can withstand countless washes.
  • Down: Down is a blanket fill used in duvets and comforters. It’s luxuriously soft and fluffy. Not only that, but the fill is durable and can last for years. However, down isn’t a good choice for people with allergies since down is bird feathers. Allergy sufferers looking for the softness of down should opt for a synthetic down alternative.
  • Synthetic: Synthetic fabrics, such as polyester and acrylic, are inexpensive and easy to care for. The fabrics are soft but tend to be staticky and wear down quickly compared to natural fabrics.
  • Fleece: Fleece is a fabric similar to wool. However, despite being named after sheep, fleece is entirely man-made. It’s warm and moisture-resistant and also inexpensive compared to wool.
  • Electric blankets: Electric blankets aren’t a blanket material, but a technology within some blankets. They contain insulated wires or some other heated elements with a synthetic cover to keep you warm. For safety reasons, keep electric blankets away from children and don’t layer them with other blankets.

Can you put big blankets in a washing machine?

Most blankets weighing up to 20 pounds fit in a standard-size washing machine. If you don’t know the exact weight of your blanket, go off your washing machine’s size—washing machines that can hold 3.7 cubic feet or more can fit up to a king-size comforter when washed alone.

If your large blankets don’t fit in a washing machine, or if they’re made from delicate materials such as wool, hand wash them in a bathtub with a mild detergent.

What is a San Marcos blanket?

San Marcos blankets are warm blankets from Mexico and considered a part of Latino culture. The blankets are heavy and cut from thick layers of acrylic. San Marcos blankets vary in size, from 60-85 by 80-95 inches. The blankets have large, printed designs, typically of animals, flowers, and rainforests.

What’s the difference between a comforter and a blanket?

All comforters are blankets, but not all blankets are comforters.

Blanket Sizes

All blankets are made with at least a single layer of fabric and don’t always have filling. Comforters and duvets are thick blankets made with two layers of fabric and then have a fill for added insulation. The fill for comforters and duvets are usually cotton, down, or down alternative.

Most people prefer a comforter or duvet as the main blanket for their bed and might use a standard, single-layer blanket as a throw on top.

How many blankets should you sleep with?

One blanket is enough for most people to sleep with. You might prefer to use a second blanket if it’s cold at night. Also, if you enjoy the feel of weighted blankets, layering two blankets is a DIY option for weight and security.

Ready to Choose the Right Blanket Size?

Blanket dimensions are useful to know when dressing your mattress or buying blankets for your baby. Also, if you want to take up knitting or crocheting, knowing the exact dimensions of your making helps you figure out exactly how much yarn to purchase for your project.

A good rule of thumb when getting blankets for your mattress is to simply get the blanket size correlating to your mattress size. However, you can always size up or down depending on your mattress’s thickness.
