King Quilt Size: Dimensions in Inches, Backing, Batting and Blocks
A king quilt finishes at about 106 x 95 inches (8.8 x 7.9 feet), which covers a 76 x 80 inch king mattress with a 15 inch drop. Published charts run 104 x 95 to 120 x 110 inches. Plan 8 5/8 yards of 42 inch backing, 12 binding strips and a king batting.
A king quilt for a 76 by 80 inch king mattress with a 15 inch drop finishes at 106 by 95 inches. That is the coverlet convention most modern quilt charts use: the mattress plus the drop down both sides and the foot, with no pillow tuck. Mattress depth runs 8 to 14 inches, so a deep mattress needs a longer drop to cover the sides.
Every planning number for a king quilt sits in the table below: 106 x 95 inches finished, batting cut to 114 x 103 inches and 12 binding strips at 2 1/2 inches, over 8 5/8 yards of 42 inch backing.
| Typical finished size | 106 x 95 in (8.8 x 7.9 ft) |
|---|---|
| Published size range | 104 x 95 to 120 x 110 in |
| Mattress | 76 x 80 in, 8 to 14 in deep |
| Quilt top area | 69.9 sq ft |
| Backing, 42 in cotton | 8 5/8 yd (3 panels) |
| Backing, 108 in wide | 3 1/4 yd |
| Binding (2 1/2 in strips) | 12 strips, 7/8 yd |
| Batting to cut | 114 x 103 in (King package) |
| Comfortable throat space | 15 in or more, or a frame |
How big should a king quilt be for your bed?
The drop is the part of the quilt that hangs over the edge of the mattress. A coverlet just clears the mattress sides, a comforter-style quilt sits a little shorter, and a bedspread runs to the floor and tucks over the pillows. The table below gives the king size for each style, measured from the 76 x 80 inch mattress top: a bedspread version runs 124 x 117 inches against 106 x 95 for the coverlet on this page.
| Style | Drop | Pillow tuck | Quilt size (in) |
|---|---|---|---|
| Coverlet | 12 in | none | 100 x 92 |
| Coverlet | 15 in | none | 106 x 95 |
| Comforter / Duvet style | 10 in | none | 96 x 90 |
| Comforter / Duvet style | 15 in | none | 106 x 95 |
| Bedspread | 20 in | 13 in | 116 x 113 |
| Bedspread | 24 in | 13 in | 124 x 117 |
For a bedspread, measure from the top of your mattress to the floor and use that as the drop, since bed frames vary. Cotton quilts also shrink about 3 to 5 percent in the first wash, so add 2 to 3 inches if an exact finished size matters. The quilt size calculator handles any mattress depth and drop.
How many blocks do you need for a king quilt?
Divide the quilt width and length by the finished block size and round to the nearest whole block. At 12 inches that is 9 blocks across and 8 down, 72 blocks in total. The table assumes no sashing or border, so the finished top is close to, but not exactly, 106 x 95 inches.
| Finished block | Across x down | Total blocks | Top size (in) |
|---|---|---|---|
| 6 in | 18 x 16 | 288 | 108 x 96 |
| 8 in | 13 x 12 | 156 | 104 x 96 |
| 10 in | 11 x 10 | 110 | 110 x 100 |
| 12 in | 9 x 8 | 72 | 108 x 96 |
| 14 in | 8 x 7 | 56 | 112 x 98 |
| 16 in | 7 x 6 | 42 | 112 x 96 |
Want fewer blocks? Add a border. A 6 inch border on all four sides removes 12 inches from each dimension of the block area. Try it in the blocks needed calculator, or see quilt block sizes for cutting sizes.
Precuts save you the cutting: a charm pack is 42 squares of 5 inches that finish at 4 1/2, and a layer cake is 42 squares of 10 inches that finish at 9 1/2, both ready to sew straight into these grids.
How much fabric does a king quilt need for backing, binding and batting?
These are the finishing materials for a 106 x 95 inch top, using 4 inches of extra backing and batting per side and 2 1/2 inch double-fold binding cut across 42 inch cotton.
- Backing: 8 5/8 yards of 42 inch cotton (3 panels, vertical seams), or 3 1/4 yards of 108 inch wide backing. Full detail on the king backing page.
- Binding: 12 strips at 2 1/2 inches, 414 inches in total, 7/8 yards. See the king binding page.
- Batting: 114 x 103 inches, so a King package (120 x 120 in) covers it. Compare types in the batting size chart, or size batting for a top that is not a standard size with the batting size calculator.
What machine do you need to quilt a king quilt?
King quilts are where sit-down longarms, midarms and frame systems earn their keep. Throat space, the distance from the needle to the machine body, decides how much quilt you can bunch to the right of the needle. For a quilt 106 inches wide, look for 15 in or more, or a frame.
Longarms and frames for king-size quilts
King quilts are heavy. A midarm, sit-down longarm or frame system lets the machine do the work instead of your shoulders.

Measure before you cut
Quilt size charts disagree by several inches. Measure your actual mattress and the drop you like on an existing blanket, then adjust. It is easier to add a border than to unpick one.

Frequently asked questions
How big is a king quilt in feet?
A king quilt of 106 x 95 inches is about 8.8 x 7.9 feet. Quilt sizes are not standardized, so patterns and shops list anything from 104 x 95 to 120 x 110 inches. Measure your own mattress width, length and depth, then add the drop you like on each side, because a thick pillow-top king mattress can eat several inches of drop.
How much fabric do I need for the back of a king quilt?
With 4 inches of extra backing on every side, a 106 x 95 inch king quilt needs a 114 x 103 inch backing. That is 8 5/8 yards of 42 inch quilting cotton sewn as 3 panels with vertical seams, or 3 1/4 yards of 108 inch wide backing. Longarm quilters may ask for 6 inches per side, so check first.
What size batting do I need for a king quilt?
Cut batting about 4 inches larger than the top on every side, so a king quilt needs roughly 114 x 103 inches. The smallest standard package that covers it is King batting at 120 x 120 inches. Package sizes vary slightly by brand, so compare the label before you buy.
How many 12 inch blocks do I need for a king quilt?
Without sashing or borders, a king quilt near 106 x 95 inches takes 9 blocks across and 8 down, 72 blocks in total, for a finished top of 108 x 96 inches. Adding a border lets you use fewer blocks and still reach the size you want. The blocks-needed calculator works out sashing and borders for you.
How much binding does a king quilt need?
A 106 x 95 inch quilt has a perimeter of 402 inches. Adding 12 inches for mitered corners and the final join, you need about 414 inches of binding, which is 12 strips cut 2 1/2 inches wide across 42 inch fabric, or 7/8 yards of fabric.
How do you calculate quilt size from a mattress?
Quilt width is the mattress width plus twice the drop, and quilt length is the mattress length plus one drop plus any pillow tuck. For this size that is 76 + (2 x 15) = 106 inches wide and 80 + 15 = 95 inches long. The drop is the distance from the top edge of the mattress to wherever you want the quilt to stop, so measure your own bed rather than trusting a chart.
How do I measure a quilt I already own?
Lay the quilt flat on a bed or floor, smooth out the wrinkles, then measure across the middle in both directions rather than along the edges, which stretch. Record width first, then length, the way quilt sizes are written: a king quilt reads 106 x 95 inches. A washed cotton quilt measures about 3 to 5 percent smaller than it did before its first wash.
Can I quilt a king quilt on a regular sewing machine?
King quilts are where sit-down longarms, midarms and frame systems earn their keep. For a quilt 106 inches wide, a throat space of 15 in or more, or a frame makes the job comfortable. A standard machine with a 6 to 7 inch harp can still quilt it with careful rolling and straight lines, but free-motion work on a big quilt is far easier with more space. Many quilters also send large tops to a longarm service.
