How it works
Add the margin to each side of the design, then find the diagonal of that padded rectangle. A round hoop of that width holds the whole rectangle.
Hoops are sold by their inside size, so choose the next size up if the number falls between two sizes.
Worked example
A design 4 in wide and 6 in tall, with 1.5 in of fabric on each side, needs a hoop about 11.4 in across.
Questions
Why not use the design width?
A round hoop has to hold the corners of a rectangle, and the corners sit farther out, so the diagonal sets the size.
How much fabric margin should I leave?
Leave enough to hold in the hoop without the design touching the edge. Many stitchers leave about an inch or more.
Can I use an oval hoop?
Yes, for an oval design. Choose a hoop wide enough for the longest side, and check the fit before you stitch.
