Quilt Sizes Chart

Here are the standard quilt sizes that most patterns and fabric shops work to. Use them as starting points — your exact quilt dimensions depend on your mattress, how much drop you want on each side, and whether the quilt tucks under pillows or lies on top of them. After the reference tables there is guidance on making the actual choices.

Standard Quilt Sizes Reference Table

These figures assume a standard mattress drop of around 16 inches per side and a pillow tuck of 18 inches at the head. They are the sizes most patterns publish and most fabric shops stock precuts to match.

• Crib: 36 by 52 inches. Fits a standard crib mattress with 6-inch sides. Uses about 3 to 4 yards of fabric total including backing and binding.
• Throw or lap: 50 by 65 inches. Not bed-sized — for sofas, chairs, or small bed toppers. Uses 5 to 6 yards total.
• Twin: 70 by 90 inches. For a standard twin or single bed with a 15-inch drop. Uses 8 to 10 yards total.
• Twin XL: 70 by 95 inches. For extra-long twin mattresses (college dorm size) with the same 15-inch drop but a longer mattress.
• Full (double): 85 by 90 inches. For a double bed with the same drop. Uses 11 to 13 yards total.
• Queen: 90 by 108 inches. For a queen mattress with a 14-inch drop. Uses 14 to 16 yards total.
• King: 108 by 108 inches. For a king mattress with a 14-inch drop. Uses 17 to 19 yards total.
• California king: 104 by 112 inches. For the longer, narrower California king mattress. Uses 17 to 19 yards total.

These numbers are finished quilt dimensions — width first, length second. If a pattern gives a quilt size that falls between two standard sizes, that is normal. Patterns are designed to finished block measurements, and the block count determines the size rather than the size determining the block count.

Mattress Dimensions for Reference

The mattress is the starting point for any bed quilt size calculation. These are standard US and UK mattress dimensions; specialty mattresses (antique beds, RVs, boat bunks) vary.

• Crib: 28 by 52 inches (standard), 24 by 38 inches (mini).
• Twin / single: 38 by 75 inches (US) or 36 by 75 inches (UK).
• Twin XL: 38 by 80 inches.
• Full / double: 54 by 75 inches (US) or 54 by 75 inches (UK small double 48 by 75).
• Queen: 60 by 80 inches (US) or 60 by 78 inches (UK king).
• King: 76 by 80 inches (US) or 72 by 78 inches (UK super king).
• California king: 72 by 84 inches. Not a common UK size.

Measure your mattress if you can. Older mattresses are often a half-inch or more different from their stated size, and that difference matters when the quilt is expected to tuck in or hang evenly. Write down the width, length, and depth (the thickness, which determines your drop allowance).

Choosing Your Drop

The drop is how far the quilt hangs past the top of the mattress. Drop affects whether the quilt covers the box spring or rests on top of it, and whether the quilt reaches the floor. Drop is a design choice, not a fixed rule.

Common drop choices:

• Coverlet drop (6 to 10 inches): the quilt rests on top of the mattress and reaches partway down the side. Used with a separate bed skirt. The standard for quilts that will be used as decorative layer over blankets.
• Standard drop (12 to 16 inches): reaches the bottom of a standard mattress or just past the box spring top. The most common drop for everyday quilts.
• Full-length drop (20 to 24 inches): reaches the floor on most beds. For quilts used as the sole bedspread without a skirt underneath.
• Puddling drop (28 inches and up): drapes onto the floor slightly. Formal look, used with four-poster beds or very tall mattresses.

Once you pick a drop, the total quilt width is mattress width plus twice the drop, and the total quilt length is mattress length plus drop (for the foot of the bed) plus pillow tuck (for the head). If your quilt sits under pillows rather than tucking, skip the pillow tuck and add only the foot drop.

Batting Sizes That Match Quilt Sizes

Commercial batting is sold in packaged sizes designed to match standard quilts, with extra for trimming. These are the common batting packages:

• Craft batting: 36 by 45 inches. Fits small projects and crib quilts.
• Throw batting: 60 by 60 inches. Covers throws, small twin quilts.
• Twin batting: 72 by 90 inches. Matches twin quilts with 2-inch margin.
• Full / queen batting: 90 by 108 inches. Covers full and queen quilts.
• King batting: 120 by 120 inches. Covers king and California king.

Batting should be at least 4 inches larger than the quilt top on all sides. Match the package size to your finished quilt plus that overhang. If your quilt is close to the limit of a package size, buy the next size up rather than trying to work with minimal margin. Batting is difficult to piece cleanly and batting seams can show through the quilt top on loft batting. Our batting calculator works out the exact package size you need from your quilt dimensions.

Yardage Estimates by Quilt Size

These totals are for standard 42-inch quilting cotton. Include quilt top fabric, backing, binding, and a small margin for corrections. Exact yardage depends on block design (pieced designs use more than whole-cloth), fabric variety (scrap quilts balance out across colours), and backing choice (wide backing is less but more expensive per yard).

• Crib quilt: 3 to 4 yards total — roughly 1.5 yards for top, 1.5 for backing, 0.5 for binding.
• Throw: 5 to 6 yards — 2 for top, 3 for backing (one seam), 0.75 for binding.
• Twin: 9 to 11 yards — 4 for top, 5 for backing (one seam), 1 for binding.
• Full / queen: 13 to 16 yards — 6 for top, 8 for backing (two seams), 1.25 for binding.
• King: 17 to 20 yards — 7 for top, 10 for backing (two seams), 1.5 for binding.

Wide-back cotton at 108 inches changes the backing portion dramatically. A queen quilt backing drops from 8 yards of 42-inch cotton to about 3.25 yards of 108-inch cotton. For the exact figure on your specific quilt, see our quilt backing fabric guide or run the numbers through the backing calculator.

When the Standard Size Is Not Right

Standard sizes are starting points, not rules. A few situations where you should depart from them:

• Deep-pillow-top or mattress-topper beds are taller than standard and need 4 to 6 inches of extra drop to look right. Measure from the top of the pillow top to the bottom of the box spring before committing to a size.
• Beds with footboards cannot take a full-length drop at the foot. Choose a coverlet drop or a standard drop that stops above the footboard rail.
• Children’s beds often benefit from a larger quilt than the standard twin. Growing bodies wrap themselves in quilts, and a twin that is 10 inches larger than standard will be used for longer before the child outgrows it.
• Guest rooms and short-use beds can get away with smaller quilts because appearance matters more than warmth coverage.
• Memory foam beds retain more heat than spring mattresses; consider the batting weight accordingly.

There is no penalty for making a quilt outside standard sizes. Patterns are easily scaled up or down by adjusting the block count, sashing width, or border width. A quilt block calculator shows how many blocks of a given finished size fit into a given quilt dimension, which is where most size customisation starts.

Matching Quilt Size to Pattern Design

Pattern books typically give sample sizes that are close to standard quilt sizes but rarely match them exactly. A pattern that produces a 72 by 84 inch quilt is in the throw-to-twin range, and the designer has made a block-count choice that balances visual design against bed fit. You can usually adjust in either direction.

To scale up a pattern, add blocks around the perimeter, widen the sashing, or expand the border. Adding one block in each direction on a block-based pattern increases the quilt dimensions by the finished block size plus sashing. Adding a 4-inch border to all four sides adds 8 inches to both width and length. Widening the sashing from 2 to 3 inches adds an inch to each sashing row — noticeable but not transformative.

To scale down, remove blocks or narrow borders. Removing a full row is preferable to shrinking block size, because shrunk blocks lose design proportions. If the pattern has sashing, narrowing it by half an inch makes a modest reduction without reworking the blocks themselves. Our dedicated quilt calculators handle these adjustments — the block layout calculation and the backing calculation both take custom dimensions, not just standard sizes.

Making a Quilt for a Blanket-Scale Project

Not every quilt goes on a bed. Throw quilts for sofas, play mats for babies, wall hangings, and gift quilts all use the construction techniques of bed quilts without the sizing constraints. For projects without a bed size to match, work backwards from the intended use.

A sofa throw should hang off one end of the sofa by about 12 inches and drape over the back or front by the same amount. Measure your sofa seat length, add 12 inches at each end, and that is your throw length. Width can match the sofa depth plus 12 inches.

A baby play mat needs to accommodate the baby plus caregiver and a toy or two. A 40 by 40 inch square is generous for tummy time; a 50 by 60 inch rectangle works for toddlers. These sizes share calculation approach with blanket-scale knitting projects — our blanket yarn calculator uses similar sizing principles for knitted or crocheted blankets.

Oversized and Undersized Quilts

Some quilters deliberately go oversize — a queen quilt made at 100 by 118 inches rather than 90 by 108 to ensure the quilt tucks deeply on both sides of a king mattress in case the bed is upgraded, or to allow for generous pillow coverage. Some go undersize — a coverlet-style twin at 60 by 80 inches that sits entirely on top of the mattress without any drop.

A few situations that regularly call for non-standard sizing:

• Upgrading from twin to full: a twin quilt that has become too small when the sleeper grew can get a border added to bring it up to full size. Add 10 inches of width and 8 inches of length to hit full dimensions from a standard twin.
• Day beds and trundle beds use twin mattresses but often have only two sides exposed. Calculate drop for the exposed sides and skip the wall side.
• Bunk beds need shorter drops on the top bunk to stay clear of the ladder, and minimal drop on the bottom bunk to avoid tripping.
• Dog beds and pet quilts follow the pet’s preferred sleeping size rather than any human standard. Most pets sleep in an area 24 to 36 inches in their longest dimension.

The calculator-driven approach to sizing remains the same for these. Measure what needs to be covered, add drop to the sides that hang free, and the target dimension falls out.

Historical Note on Quilt Sizing

Historical quilts often do not match modern standard sizes because beds themselves have grown over time. A Victorian bed was typically 4 feet 6 inches wide at most, and many antique quilts measure 70 by 80 inches or smaller. If you are replicating an antique pattern, the size charts in pattern books from that era are more useful than modern charts.

Modern quilting arrived at standard sizes because pattern publishers, precut manufacturers, and batting makers all benefit from agreeing on common dimensions. Follow them when it helps you plan; depart from them when your bed or your project demands it.

For yarn-related blanket planning, the yarn weight guide covers how yarn weight affects blanket thickness and the yardage required. Blankets in knitting and crochet use similar sizing principles but different material calculations. And for fabric-level decisions that feed into every quilt project, the fabric widths guide covers how bolt width affects piecing.
