The inside dimension of this hoop is 4 3/8″ (4.375″, or 111mm)
Actual sewing area depends on brand of machine approximately 3.6″ or 91mm

This hoop has an inside dimension that is 4.375″ round. That dimension is the same size as a standard Tajima 12cm hoop, as well as many other hoop brands. Please note that your actual sewing area will be determined by the size of your presser foot. Most machines will be able to sew approximately 3 3/8 to 3 5/8″. This Mighty Hoop was designed for items like sleeves and cap backs. It was not made to hold thick and heavy items, like the original Mighty Hoops. It was designed with smaller magnets allowing it to have a smaller outer ring. This makes it easier to get into tight areas. It will not be able to hoop thick bags, workwear, leather, or other difficult fabric. The 4.25″square Mighty Hoop would be a better option for that type of embroidery. The 4.375″ Mighty Hoop will fit most commercial embroidery machines, including the Brother and Baby Lock 6 and 10 needle machines.

Additional information

See the list at the bottom of this page to see if we need a measurement for your brand.

If your machine is in the first group on the bottom of this page then we need measurements of your existing hoops so that we can get you the correct adaptor brackets for your new Mighty Hoops. Please measure at least one of your 15cm size hoops and all sizes of jacket back hoops you have. Even if the jacket back hoop is larger or smaller than the one you are ordering, send us all the different sewing field sizes. This will tell us what sewing field sizes your machine can take. You can measure in inches or millimeters, but millimeters is easier to be accurate.

Barudan Machines

If you have a Barudan Machine we will also need to know if you have the EFP or QS Brackets. Here are pictures of the ends of each of these brackets. The EFP was used on machines that are at least 5 or more years old. Only look at the ends of the brackets, the length or shape of the rest of the bracket will change on different size hoops.

The x’s designate that we can make a Mighty Hoop for the particular machine and sewing field. You can provide us with the actual mm or inch measurement or what the manufacturer calls the size. Example, if you have a SWF with hoops that measure 494mm, you can tell us 494mm, 19 7/16 or SWF 500 Sewing field.
