Most dice are 16mm on a side. With 1" x 0.5" labels for your printer, you can create your own dice labels using 3 labels per die.
The file is an editable Word document with labels for 8 sets of operations dice, powers of 10 dice, numbers 5-10 dice, fractions dice, percent dice and decimal dice. Use as is, or edit the labels to be what you need. The file can be printed onto label sheets with these specs:
Top margin: 0.5"
Bottom margin: 0.5"
Side margin: 0.25"
Label height: 0.5"
Label width: 1" (the file has 2 @ 1/2" faces per label)
Number across: 8 (the file has 2 @ 1/2" faces per label)
Number down: 20
Not sure if they'll line up? Try printing to blank paper first, and then put a label sheet on top, and see if they line up.
To find 1" by 0.5" inch printer labels, just try searching for that in an internet browser.
