Several Avery business cards are 10 per sheet, 2x3-1/2 inches. The different numbers represent different colors, textures, pack sizes or printer compatibility (inkjet or laser or both), but most of the 10/sheet business cards share the same template. The exception is our glossy business cards, which have a gap down the middle so have their own template.
You can design these using the 8371 template in Avery Design & Print Online
You can also use a template built into Microsoft Word or download an Avery 8371 template for Word, Photoshop, Illustrator, InDesign or Pages.
Here's some information on recommended printer settings.
