Printable on US Letter size paper (8.5"x11" or 21.59cm x 27.94cm), you'll need a pdf reader to open. Opened with Adobe, you'll be able to edit the nameplates with your student's names, subjects, words, etc.
Once printed, you'll be able to line up a ruler between the white dots on the sheet (around the edges) and cut them apart to 11" x 2.833". They can also be cut down to the traditional 9.5"x 2.833" nameplate size as well.
