12 inch blocks. Help needed to figure out how many for King
 

Hello friends,
Doing the math is such a problem for me.
I'm making a Log Cabin for our King bed. The blocks are 12 inches and they are coming out nicely. I've made 27 so far but have no clue how many I need for my bed.
I keep putting them on the bed to see how much progress I'm making and the kittens pounce the minute they see me doing it :D
Any ideas? Good thing I wasn't a Math major, haha

Although there are some guideline sizes for bed quilts, they can vary widely:
How long a drop do you want? Just cover the bed? down to a dust ruffle (add at least 14" to 3 sides) to the floor (add at least 20" to three sides), pillow tuck? (add at least 24" to top). If you can give us an idea of what you are aiming for, we can give you a good idea. BTW, I was a math major. It always doesn't help!

Princess, thanks for your response. I believe a King is 98x98 and I want it bigger, more like 110 x110. I like some overage.

10 blocks across and 10 down would give you 120" 9 blocks down and 9 across would give you 108.. (I
m assuming you mean 12" finished). So either 100 blocks or 91 blocks. Maybe do the 9 x 9 and a border?

In the US, a king bed is either 76x80 (standard king) or 72x84 (California king). The mattress can be anywhere from 5 to 20 inches deep, and a box spring can add to that, so a 10-inch drop can be too little, depending on the bed and how much of the mattress and box spring you want to cover. It would be best to get the precise measurements of the mattress and box spring, also whether there is a footboard, etc.

12”x 9=108” so to get a 108 x108” finished quilt you would need 81 blocks (9 x9) of the 12” finished blocks.

Oh that's great, thanks! It looks like I have a lot to go!!!!!!! :D

Thanks to all. Tartan, that's a great idea, thanks!

Graph paper is your friend, you can decide how many blocks you want and if you want to add borders how many what size

I don't know where I got the idea that a King is 98x98. I think Dunster is correct on this. I will get out the graph paper.
Thanks everyone.

When I made a custom quilt bedspread for my new bed, I measured my actual bed. My bed is a queen, with a Temperpedic mattress (which tend to be thicker than some) on a canopy frame (again, taller than average), so my quilt bedspread is 110” x 112”. If you are making it for your bed, or whomever’s bed, measure the bed and make it that size.

If you use sashing, that throws it all off. I want to cover the mattress with the main square and then some borders and some drop. But that is just me. That's why I stick to Queen size.

Did everyone forget the borders? On a quilt that size the borders (unless you are skipping them altogether) need to be about 5 - 6" wide to be in scale. That would knock off a block in each direction. Will there be any sashing? Most log cabin quilts skip sashing, but I have seen it very nicely done.
