How to Determine the Frame Size for the Calculator

1.)  The frame size is always considered to be the size of the recess at the
      back of the frame that contains the glass, mat, art and backing you
      load into it.  This recess is known as the "rabbet" of the frame.

2.)  The frame size conforms to what you load into it.  So if you know
      the size of any of the items you will load into it, you also know the
      size of the frame, and this is the size you will enter into the calculator.

3.)  Special instructions for floater frames. Floater frames are cut to the size of
      the artwork unless otherwise specified. If you want to acheive the affect
      of the artwork floating within the walls of the frame, add 1/4" to the width
      and height of the artwork. This will give you an 1/8" space between the edges
      of the artwork and the walls of the frame. This only pertains to floater frames.

     Some examples:

     You want to frame art under glass but without a mat.
     Measure the width and height of the art.  This is what you
     enter into the calculator.

    You want to frame art that is matted.
    Measure the overall size of the mat.  This is what you
    enter into the calculator.

    You want to frame art mounted on a backing board
    without a window mat.
    Measure the overall size of the backing board.  This
    what you enter into the calculator.
