How do you calculate yardage for larger quilt?
 

The pattern is 62 x 72. I want to make a duvet cover 108 x 94 (a king comforter.)

I thought I knew a way to calculate but I think I bought too much fabric. I still have one more to purchase and don't want to buy way too much.

My son is a carpenter and tried to draw me a picture but he was working in feet. I think I want to calculate in inches.

Thanks. I know someone out there can clear it up for me.

Try googleing "figuring yardage for quilts" or something like that; you'll find many sites to help.

It's tedious but I calculate in square inches. Figure out how many square inches of each color per block. Multiple by number of blocks. There are 1584 sq. in. per yard of fabric (based on 44" wof) divide total from blocks by #/sq. yd. That's how many yards you need. I usually over buy up to the next 1/2 to full yard just for cutting/sewing booboos but otherwise it's usually pretty accurate.

If it helps, the duvet cover you want is about 2.3 times as big as the pattern. Other things being equal, I would buy 2.5 times as much of each fabric and look forward to the leftovers. (Actually *I* wouldn't do that. I would make a spreadsheet, figure out exactly how much of each fabric I needed, obsess about the accuracy of my figures and the fabric selection, then either find it in my stash or buy way too much anyway, changing my mind about the layout, the fabrics, the pattern, and everything else several times while sewing.)

If you're buying 54" wide material or 45" wide material, you need to figure out how many panels.....

108" = 3yds

54 wide fabric ~ 2 panels x3 yd=6 yds fabric + a bit extra - I'd get 6 1`/2 yds
45 wide fabric ~ 3 panels x 3 yds = 9 yds fabric + bit extra - 9 1/2 or 9 3/4 yds fabric depending on the extra needed

give or take....,but gets me close

It also depends on how you are going to enlarge the pattern. Make more blocks? Make bigger blocks? Make the original pattern and then add borders? If you are doing borders, and don't want to piece them you would need at least 3 yards for the last one to get the 108 inches, even though you would only use about a 12" strip of it for a 4" border.

I look at what size the finished block is and then the size quilt I want to make. You can usually just add another row of blocks top and side to make it bigger. Then I count how many new blocks I would need to make that size and how many blocks are in the original size. It usually is around twice the blocks, sometimes less. If less, you can just double the yardage, if same or more, add more for extra needed for borders. Sometimes, I have cut out the original size except for borders, then figure how much more is needed for the extra blocks, as most times the pattern calls for more than needed.

I have a quilters calc, works great for me!!!

Oh this sounds so familiar!! I don't think my quilts ever end up the way I originally planned.... the good thing is that buying too much fabric only adds to your stash!! :)

if your son calculates it in feet simply multiply by 12- to get inches....then you can divide by 36 to get yards.
