Quilt Sizes on Patterns are NOT Consistent
Don't assume a "queen size" pattern will fit YOUR queen size bed.

The quilt sizes listed on patterns are not consistent from one pattern
Designers follow no hard and fast rule (when determining the
finished sizes) that a large quilt should fit a bed nicely—i.e. that there is an even overhang off the sides, and it is both wide enough and long enough to cover the mattress.
What's a Quilter To Do...???
It all depends on who and what the quilt is intended for and...
...are you willing to adjust the block or sashing sizes and/or numbers to get the look you desire?
If it matters to you how your patchwork creation covers the bed because it is the focal point of the room, then you'll want to learn how to...
Calculate the Correct Sizes for Your Needs
If your patchwork is intended for a specific bed, you'll need some or all of the following information.
We've got you covered!
There's a worksheet to print a bit further down this page to help you organize this information!
Specific Bed Measurements...
- Mattress Dimensions: Width and length. (For
an online chart of standard US mattress dimensions, commercially made
comforter and coverlet sizes, and pre-cut packaged batting sizes for King, Queen, Full, Twin and Crib sizes go to Standard Quilt Sizes and Mattresses Chart page.)
Depth: Standard and older mattresses can be 8"-12" deep, while newer
pillow top mattresses are generally 14"-18" thick or even more.
- Box Spring Depth: There may be no box spring if the mattress is on a platform.
- Height: From the top of the mattress to the floor
Determine the "drop" you'll need...
"Drop" is the portion of your quilt that hangs off the sides of your bed. Several things affect how much drop you'll need.
- Is there a dust ruffle or bed skirt? A coverlet drops about 3" below mattress bottom to cover the top of the dust ruffle.
- Will it drop to the floor? You'll need to know the bed height. A full length quilt drops to within 1/2" of the floor.
the it cover the mattress and box spring? You'll need the mattress
depth plus box spring depth plus a few inches for insurance.
- Is it a daybed? You may need drop only on one side.
- Is there a foot board? You may only need drop on the front edge.
- Will the pillows be tucked in or will you use pillow shams? Add an extra 10"-18" for a pillow tuck.
quilts are designed with borders on all four sides. Is this appropriate for your situation? Can you leave off the top border and add a
row or two to make the quilt fit properly?
Many patterns don't include sizes that are designed with an even drop on the sides and
bottom edge. If this bothers you, adjust the pattern before you cut and
Other things affect your finished quilt sizes...
dense will your quilting be? The more dense the quilting, the more the
finished quilt will "draw up" or shrink. For dense quilting add an
additional 5% to your drop calculations.
- Will you
use a cotton batting to get the "puckered" look of an antique quilt?
Check your batting to see how much it shrinks when washed and add that
back into your drop calculations.
- Is there a
medallion or central design that you want centered on the top of the
bed? If this central design doesn't fit properly on your bed, can you
alter the quilt pattern to fix this problem?
