There is no right or wrong answer when it comes to size. Your shadow box can be as big or small as you need to hold your photographs or items. For custom designs, simply tell us the dimensions of the items you plan on placing inside and we can create a frame that is the perfect size to offer a beautiful display of your pieces. It is a good idea to figure out the layout of how you plan on displaying your items before ordering your frame, so that we can ensure the frame is big enough to display your memories exactly as you intended.
