18" Arm
Your Tin Lizzie 18 has an arm length of 18". This is the space from the needle to the back of the machine. This is important to you as it will allow you to use 12" patterns when quilting even on a king size quilt when you set your frame up with 10 foot pipes. Also if your quilt is made up of 12 inch blocks then you will be able to quilt each of your 12 inch blocks without having to turn the quilt.
