What size should my finished quilt be?

When starting out on your patchwork and quilting adventures, determining what size to make your quilt can be a cause for some frustration.   If you are following a commercial pattern, the finished size of your quilt will often be pre-determined for you.  Many commercially available quilt patterns use US sizes and often they will include the instructions for quilts in a number of different sizes.  This can be confusing if you are not familiar with US mattress sizes and their UK equivalents.  We’ve put together a simple comparison for you at the bottom of this article to help you understand how the common US quilt sizes relate to UK beds.

The size of your quilt will also depend on who you are making it for, where you intend to use it and how you intend to use it. 

Ask yourself these questions to help you determine what size your quilt should be:

  • Who is the quilt for?
  • What is the quilt for?
  • How do you intend to use it?
    • Do you want to use your quilt as an additional bedcovering?
    • Do you want your quilt to drape down the sides of the mattress or do you want to just display it on the bed?

Ultimately, the size of your finished quilt in entirely up to you but we hope that this article will help you to determine what is best for you and your latest quilting project.

Happy Stitching!
