The size field will print on the label. It is not a required field and we suggest not using. The field itself will allow you to enter more characters than will fit on the label. This field does not cut-off but will spill into the next field. The line then becomes unreadable. It was intended to clothing, i.e., S for Small or M for Medium. If you use this field be sure to verify what is printing on your labels before you print.
