The actual embroidery field is about 1/2 inch smaller than the hoop size. Pay attention to hoop sizes as it does matter. Here is a little help to understand hoop sizes and the embroidery field.

My magnetic hoop (inside) is 17 x 10.5. The design field is only 9x14. If I move or rotate a design out of field, the machine tells me to use a larger hoop.
The machine needs room for the embroidery foot to move so you don't hit the edge of the hoop.
Be sure to set the hoop size in the machine preference page if you have that feature.
