The smallest size (that will look good) is about 1.5″ square. If a lenticular is smaller than that, fine lines will begin to break up under the lens. The largest size we can produce via litho is 26″x 38.″ However, we can now produce panels as large as 48”x 96” and we can tile those into even larger displays. We can likely help no matter what size you are looking to produce.
