The Goldilocks of our frames… not too big, not too small. Also, the most common hoop size in modern embroidery kits.

But which one? Hoops sold as "6in" vary quite a bit in their actual size. Measure the diameter of the hoop you'd like to frame to select the best fitting frame. How to Measure

For 6.0" hoop, order 6SM.
For 6.25 or 6 3/8" hoops, order the 6MD. This is the most common size for "6in hoops".
For a 6.5" hoop, order 6LG.
For 6.8" hoops or Nurge No.3, order the 6XL.
