Quilt size chart: common finished sizes

| Crib | 36 x 52 | 91 x 132 | Crib mattress 28 x 52 in | |

The sizes printed on patterns are only a starting point, because the same word can mean different things to different designers. One pattern’s queen can be several inches narrower than another’s, and neither is wrong. What matters is how the finished quilt sits on your bed: how far it hangs down the sides, whether it reaches the foot, and whether it folds over the pillows.
That is why this page pairs a quilt size chart with a planner. Choose a bed, or type your own mattress size, and set the drop you want. The planner gives you a finished size and shows it to scale, so you can see the result before you buy any fabric. Once you have a size, carry it into the backing, batting and binding calculators to finish your shopping list.
The chart and the planner both work in centimeters as well, so you can check a metric pattern against your bed.
A quick test with a bedsheet is also worth trying, since you can fold it to your planned size, lay it over the bed and see how it looks before you commit.

How to read a quilt size chart
A quilt size chart lists finished measurements, which means the size after the quilt is pieced, quilted and bound. Each row is a convention rather than a rule. Our chart follows the sizes published by Missouri Star Quilt Co., one of the most widely referenced charts in quilting, and you will find small differences elsewhere. A queen might be listed at 90 x 95 in on one chart and 90 x 108 in on another, because the second one assumes a longer drop and room for pillows.
The width usually matters most. A quilt that is too narrow leaves the mattress edges showing, while a quilt that is a little short is often hidden by pillows. If you are comparing two sizes and cannot decide, choose the wider one, since it is easier to make a quilt look generous than to add a border after the top is finished.
The formula behind a custom quilt size
You only need two sums. Quilt width equals the mattress width plus two times the side drop. Quilt length equals the mattress length plus the foot drop, plus the pillow tuck if you want one. For a queen mattress of 60 x 80 in, with a 12 in drop and a 10 in pillow tuck, the width is 60 + 24 = 84 in and the length is 80 + 12 + 10 = 102 in.
That result is noticeably different from a standard queen chart size of 90 x 95 in, and this is the most useful thing the planner shows you. Charts are compromises. The 90 in width gives a deeper drop on the sides, and the 95 in length leaves less for the pillows. Neither is a mistake, so decide which of those you care about and enter it.
How to measure your bed for a quilt
Measure the bed you actually own, with its usual bedding on it. Run a tape across the top of the mattress from edge to edge, then from the head to the foot. For the drop, measure from the top edge of the mattress down to where you want the quilt to stop. A drop that just covers the mattress is often 10 to 12 in, and a drop that also covers a box spring or frame can reach 18 in or more.
Pillow-top and extra-deep mattresses can add several inches of height, and that eats into your drop. A bed against a wall needs less width on that side, and a footboard may mean you want no foot drop at all. Enter 0 for any drop you do not need. The planner accepts fractions, so you can type 60 1/2 exactly as you read it from the tape.
Sizes for quilts that do not go on a bed
Baby and lap quilts are decided by use rather than by a mattress. Handmade baby quilts commonly range from about 30 x 30 in to 40 x 50 in, and a quilt for a crib is usually around 36 x 52 in. Note that safe sleep guidance in the United States advises keeping loose bedding out of an infant’s sleep space, so many baby quilts are made for floor play, a stroller or a keepsake.
A throw or lap quilt is usually around 50 x 65 in, big enough to cover one adult on a sofa. For a taller person, or to share, 60 x 80 in is a common choice. To plan these, set the bed to Custom and type the size you would like, with the drops set to 0, and the rest of your calculations will follow from that number.
Turning a quilt size into a shopping list
Once you know your finished size, the rest of the plan follows quickly. Backing and batting both need to be larger than the quilt top, because quilting draws the layers in and the longarm or your machine needs room to hold them. Binding depends on the distance around the edge. Use the quilt backing calculator and the batting size calculator next, then the quilt binding calculator.
Remember that heavy quilting can shrink a quilt slightly, and so can washing it once it is finished, especially with cotton batting. If an exact fit matters, add an inch or two to your plan. If you are choosing a size for your first quilt, a throw is a sensible place to start, because it is easy to handle on a home machine and uses far less fabric than a bed quilt.
Common mistakes when choosing a quilt size
The most common mistake is planning from the mattress label instead of the real bed. Measure with your usual bedding on it, because a thick topper or a duvet underneath can use up several inches of drop. The second mistake is forgetting who will use the quilt. A person who likes to tuck the quilt in at the foot wants more length than the chart suggests, and two people sharing a bed tend to want more width, so that nobody loses the covers during the night.
Another trap is ignoring how the size affects your machine. A king quilt is heavy and bulky to push through a home sewing machine, so if you plan to quilt it yourself, consider a straight-line design or a longarm service. It is also easy to forget the block size. Patterns grow in steps of one whole block, so the nearest pattern size may be several inches away from your plan. Instead of forcing a fit, you can usually add or remove a border to reach the size you want. Decide this before you cut your borders, while the change is still easy to make.
Frequently asked questions
What is the standard size of a queen quilt?
A common queen size is 90 x 95 in, though some charts list 90 x 108 in. There is no official standard, so measure your bed and use the planner above if the fit matters.
What size is a king size quilt?
A common king quilt is 108 x 95 in, for a 76 x 80 in mattress. A California king mattress is narrower and longer at 72 x 84 in, so its quilt is usually about 102 x 100 in.
What size is a twin quilt?
A common twin quilt is 68 x 86 in, for a 38 x 75 in mattress. A twin XL mattress is 5 in longer, which is worth checking if the quilt is going to a college dorm.
What size is a lap quilt?
A lap or throw quilt is commonly about 50 x 65 in. Many quilters make them up to 60 x 80 in for taller people or for sharing on a sofa.
What size is a baby quilt?
Handmade baby quilts usually range from about 30 x 30 in to 40 x 50 in, and a crib quilt is commonly 36 x 52 in. They are often used for floor play or as a keepsake rather than for sleep.
How much drop should a quilt have?
A drop of 10 to 12 in usually covers the sides of a mattress. Allow more if you want to hide a box spring or bed frame, and measure your own bed, because mattress depth varies a lot.
Sources and method
Finished sizes and mattress sizes follow Missouri Star Quilt Co.’s quilt size chart, except twin XL, which uses the common US size of 38 x 80 in. The width and length formula is standard quilt planning arithmetic. Published charts differ, and no body sets an official size.
