Framing Components FAQ

How do I measure artwork for a custom mat, backing and/or plexi?

Use a standard tape measure and record your exact width and height. How you enter those measurements depends on your order type:

  • Backing and plexi without a mat: Enter your exact dimensions.
  • FrameShop (standard mats): Enter your exact dimensions, and our system automatically applies a 1/8" overlap on all sides so artwork will not fall through (you can turn this overlap off).
  • When selecting backing and/or plexi with the mat, our system takes care of the outside dimensions to match the mat dimensions.
