What Is The Size Of A Baby Cot Quilt?

Handmade baby quilts are a priceless gift because they allow you to choose colours, themes, or special fabrics that hold a special meaning. Plus, nothing says that you care about a new life as much as the hours you put into making a unique blanket just for that precious little one! If you wonder how big to make your blanket, you may want to refer to this complete guide for baby quilt sizes before you begin.

The most popular sizes for baby quilts include a 30” X 40” newborn or baby quilt and a 30” X30” preemie quilt. As babies grow, a 36” X 56” crib quilt works nicely. Babies and parents together also enjoy a 50” X 65” lap quilt or throw.

In this article, you will find several handy charts to help you plan the sizing of your baby quilt. You will learn about the four most common sizes of baby quilts. Finally, you will find tips for making a baby quilt and what kind of material to use.

Baby Nursery FAQs

Approximately 38"- 40" x 45"- 46"is our guideline. However, bearing in mind that these comfort quilts are given to kids from birth to 22 years of age, slightly longer quilts with less juvenile themes can be set aside for older children.

The Most Common Baby Quilt Sizes

how do you sew a baby cot sheet

30″ X 30″

This size is perfect for newborns! Although it won’t last forever in terms of size (sounds like a good excuse to make another quilt, huh?), as your baby outgrows it, the quilt can become a play mat or carry along a “just in case” quilt. One of the best parts of making a small 30″ square quilt? You only need one yard of fabric for the backing.

30″ X 40″

For those who prefer a rectangular size, this longer quilt gives your tot plenty of room to grow. And don’t worry — you can still easily use yardage for the backing without having to piece it. 

36″ X 52″

This has become a standard size because it fits well over a crib mattress, which is usually around 28″ x 52″. But an important safety note: the American Association of Pediatrics recommends a bare crib (no quilts or blankets) for infant safety. So the crib size is less important than a size that the parents will appreciate.

Anything larger than 36″, whether square or rectangular, also makes a great floor covering for babies on the move — and larger quilts are sure to be used as the child grows and begins sleeping with covers.

The best size square for a baby quilt is usually four or five inches, but this does depend on the size of the whole quilt. You want your quilt squares to easily divide into the total area you have selected as the quilt size!

Other popular quilt square sizes include 6” squares and 12” squares. You will also find some popular baby quilt patterns that use 10” squares.

But how do you know how many squares to use in your quilt?

Here is an easy way to figure out the number of squares needed for your quilt: first, multiply the length of the vertical and horizontal sides of the quilt. This gives you the total area of the quilt in inches.

Next, figure out the area of your quilt square. For a five-inch square, multiply five times five.

Finally, divide the total area of the quilt with the area of each square. So, for a 30” X 30” quilt made with 5” squares, you would do this math:

30 X 30 = 900

5 X 5 = 25

900 ÷ 25 = 36

This means you would need 36 five-inch squares to make a 30-inch quilt!

Suppose all that math seems like way too much work. You can also find free online quilt calculators to help you out, like this one. Some advanced quilt calculators will adjust the calculation to include a seam allowance on your quilt squares.

Four Standard Baby Quilt Sizes

The four most popular standard baby quilt sizes include a preemie quilt size, a crib quilt, a toddler quilt, and a lap quilt size. Of course, you can make a handmade quilt in pretty much any size you want! But choosing a standard size is easier because you can find many resources to help you cut out and plan your quilt in those popular sizes.

One easy way to pick the best quilt size is to choose a size intended for the baby’s age. For instance, newborn quilts usually come in small squares, while toddler quilts come in larger rectangles.

Preemie And Newborn Quilt

The most popular size for a preemie or newborn baby quilt is a 30” square. However, you will see some variations on this. Some organisations recommend quilts as small as 22” square for preemies, while others like the extra room provided in a 30” X 30” blanket.

A 30” square also works great for newborns in general and is a great gift to brand-new parents who may want to use the quilt in the hospital or as a car seat cover on the way home. This size is small, compact, and easy to maneuver while handling all the “baby paraphernalia” like diaper bags and strollers.

One of the great things about this small, square baby quilt is that you can easily use a solid piece of fabric for the quilt’s backing rather than piece together fabric as you would for a larger quilt.

Plus, making a square quilt also simplifies the quilt blocking process!

That said, a 30” X 40” rectangle comes in as a close second for a popular baby quilt size for newborns, too. If you prefer a rectangular quilt, this slightly larger measurement does give you a bigger canvas to work on as you create your unique quilted pattern!

Crib Or Cot Quilt

Baby cribs or cots almost always have a standard-sized mattress, which means that a standard size quilt should fit that mattress with 36” X 52” measurements. This sort of quilt, coming in at a much larger size than the average newborn blanket, will likely stay with the baby through much of their early childhood!

However, please note that experts do not advise allowing infants to sleep with heavy quilts or blankets. This kind of crib quilt mostly serves a decorative purpose in the crib until the baby is six months old or older.

On the other hand, a baby will quickly outgrow the newborn-sized 30” square quilt, while this nice big crib-sized quilt will remain cozy for years to come! Parents can use this quilt size as a floor mat or as a lap throw.

Toddler Quilt

The most popular size for a toddler quilt is 46” X 70”, which will fit the standard-sized toddler mattress. However, you also see many toddler quilts made in either the standard crib quilt size of 36” X 52” or a rectangle as big as 70” X 90”, depending on the size of the toddler’s bed.

Toddlers range in age from two years old to four or five years old. If you want to create a gift that the new little one can enjoy for a very long time, you may want to consider making a toddler quilt.

Of course, you will want to consider that you will need more fabric for this larger blanket. The average toddler blanket will require about one ⅔ yard of fabric for the front of the quilt and batting and material for the quilt backing.

Lap Quilt

The most popular size for a lap quilt is 46” X 60”, though you will see a lot of variation in sizing for this quilt style. This is because this quilt does not need to fit over a standard-sized mattress. Instead, parents can use it to snuggle up together with the new baby!

The only real rule with a lap quilt is that you want it to allow enough room to cover the adult and child together generously. The benefit of using one of the more popular sizes, like 46” X 60”, is that you can often find free patterns or quilt blocking designs online when using a more standard measurement.

Other popular sizes for a lap quilt include 36” X 48” and a 36” X 36” square. A 36-inch square baby quilt also makes a popular floor mat or playspace!

You can make lap quilts quite simply if you want to stitch up your design quickly, but you also do some very intricate, artistic designs used in lap quilts in particular. These blankets sometimes do not see quite such hard use as a crib quilt or a newborn quilt, so you can more easily invest a lot of time in making them beautiful!

  • Baby — Baby quilts are typically square in shape and range from 36 inches / 91cm by 36 inches / 91cm, up to 52 inches / 132cm by 52 inches / 132cm. Either one or any measurement in between will be big enough to keep the baby snugly warm on even the coldest winter day.
  • Crib — Crib quilts typically measure between 30 inches / 76 cm by 46 inches / 117cm and 36 inches /91cm by 50 inches / 127cm. They're rectangular and will fit most crib mattresses when made to fall within these measurements.
  • Toddler Bed — Quilts for toddler beds are rectangular and should measure about 46 inches / 117cm by 70 / 178cm inches to fit a standard-size toddler mattress.
  • Lap — Lap quilts can be square or rectangular, depending on how you decide to make them. There are a lot of leeways where lap quilts are concerned, and you can make yours in nearly any size you choose. A good place to start is around 52 inches / 132 cm by 52 inches / 132cm, up to 52 inches / 132cm by 78 inches / 198cm. It all depends on whether you want a light coverlet to go over your lap or if you plan to snuggle up with a favourite someone on the couch.
  • Twin — A twin-size quilt usually begins around 64 inches / 163cm by 86 inches / 218cm, but measurements can go as high as 72 inches / 183cm by 96 inches / 244cm if you want a nice drape over the sides of the bed.
  • Full — A good place to start for a full-size quilt is 70 inches / 178cm by 88 inches / 224cm or 88 inches / 224cm by 100 inches / 254cm. Again, it just depends on the drape.
  • Queen — Queen-size quilts usually measure around 99 inches / 252cm by 108 inches / 274cm.
  • King — For your king-size bed, you'll want a coverlet that measures at least 108 inches / 274cm by 108 inches / 274cm for excellent coverage all around.

Depending upon where you look on the internet for standard quilt sizes, you're going to find quite a bit of variation. The measurements listed here tend to be generous to allow the quilt to drape nicely over all sides of the bed. But smaller quilts are fine too.

For the best fit, break out the tape measure and take the exact measurements of the bed you're trying to dress and then allow extra inches for overhang on all sides. Crazy Mom Quilts has a great tutorial for learning exactly how to measure your bed. If you want your quilt to cover and tuck beneath your pillows, you'll want to allow for that as well.

Kind Of Fabric Should You Use In A Baby Quilt

how to establish a bedtime routine for your baby3

The most popular fabric types in baby quilts include organic quilting cotton, quilting cotton, and cotton flannel. Many quilters prefer using organic cotton that has all the benefits of quilting cotton but is guaranteed to be safe against a baby’s sensitive skin because the organic fabric will not contain any chemicals or pesticides.

Why does cotton make the best baby quilts? First, you can throw cotton in your washing machine without ruining it. Babies tend to make a lot of mess, so you need to use a washable fabric!

Plus, cotton absorbs moisture easily and has excellent breathability. This means it can keep a baby warm without becoming stifling or clingy.

And, of course, cotton has a lovely soft feel to it. If you want an extra-soft cotton fabric for your quilt, you may even want to use a cotton flannel. Many fabric stores sell this kind of material in all sorts of adorable child-friendly prints and colours.

You may feel tempted by the cheaper synthetic quilting fabrics you see for sale. However, synthetic fabric like polyester may cause an allergic reaction in some infants. For this reason, it’s a good idea to choose an all-natural fabric like cotton for your handmade baby blanket.

Washing And Taking Care Of Baby’s Quilt

The biggest difference between a baby's quilt and any other quilt is maintenance. For the large quilts (for your king-size bed, for example) made from natural materials, it is not recommended to wash them too often. But we know what babies are like. 

They are messy. There will be stains everywhere! At the same time, little ones are extremely sensitive to dust and dirt, and we need to make sure that our quilt is not just warm and comfortable but also safe and healthy for the little ones.

As long as you think about that before choosing your fabrics, you will be fine. Make sure you get fabrics labelled with pre-washed and pre-shrunk, so there will not be any unpleasant surprises.

There are a few additional tips you can follow to ensure a longer-lasting softness of your quilts while making your baby’s health a priority:

  • Please put it in the washer but use a gentle cycle.
  • Use an appropriate detergent that will protect your baby’s sensitive skin.
  • ​Do not add fabric softener. This includes dryer sheets.
  • Tumble, Fluff, or Air dry.

Some Final Tips For Baby Quilts

Use this guide and information you got just as a reference and:

  • Always check mattress size before you buy fabric.
  • Always add a few inches on your measurements – you can never have too much fabric.
  • ​You can be incredibly creative, and that’s the beauty of quilt making (you can add smooth edges that babies adore).
  • ​Add personal mementoes.
  • Make a bigger quilt from the one your baby has outgrown.


Baby quilts usually come in four standard sizes for newborns or preemies, baby cribs, toddlers, and lap throws. While you can find some variation in the measurements commonly used for each of these standard types of baby quilts, using the most common measurements will help you easily plan your handmade quilt. 

Newborn quilts often measure 30” X 30”, crib quilts usually measure 36” X 52”, toddler quilts can measure as large as 70” X 90”, and lap throw quilts often measure 46” X 60”.

You will also need to find a piece of batting that measures about 60 to 8 inches larger than the surface of your quilt. This will provide a warm insulating layer inside the blanket.
