Says it has a throat of 8.5". Awfully small for quilting large quilts - you will only be able to do small designs and will have to make more quilting rows. And with a queen or larger, you may only be able to quilt half of the quilt before you run out of space in the throat area - then your only option would be to take off the rails with the quilt on it, turn them around, and finish quilting the other half.
