I originally bought this to do roundel masks with my circle cutter, and possibly US markings as well. Works well for this purpose of course but it hit me that I could send this through my inkjet printer, and copy the decal sheet for guidance, albeit a little inefficient on space. It worked! Had to use the rear feed and tape it to a regular sized piece of paper. The sheet is roughly 24mm x 18mm, or 9.5 inches x 7 inches. Takes a while for the ink to dry and even then not fully colorfast, might consider cleaning with alcohol after cutting the mask. This has given me another idea, ie, sending through my Cricut!!! I wish Tamiya offered standard paper sizes though.
