Allied Wooden Hoop Sizes / Dimensions

All of our wood embroidery hoop dimensions are given on the product listings as the distance in the Y direction (top to bottom) by the X direction (left to right), i.e. Y by X. These values are the measurements of one inside wall of the inner hoop to the other inside wall in millimeters.  For example, in the below hoop, the Y measurement is 320 mm (12.6") and the X measurement is 100 mm (3.9").  Therefore, the hoop item number would be AWH-320100-SH-abc-000. (SH designates Single Height, abc designates hoop brand, 000 designates arm spacing distance/ Sew Field). To convert millimeters to inches, divide the value in millimeters by 25.4.
