I use Libre office free, because screw MS, but anyway your spreadsheet would differ from anyone else's because of your printer and chosen sticker size. Suckers/labels come with templates or downloads, although they're usually for the word processor.

I generally use print preview to box off a page size, then drag to resize rows and columns to fit. Test print blank pages on normal paper. You can turn on or put lines around the cells to see them better and then turn them off when ready to print the sticker sheet.
