Common sizes range from 3 x 5 inches up to 5 x 8 inches; 4 x 6 inches is also frequently offered.
Many cards are ruled on one side with a blank back. Common ruling types include college and narrow rulings, with some options offering other specialty rulings.
Index cards are typically made from paper or cardstock and are generally uncoated. Some bound sets include a poly front cover for added protection.
Cards are easy to write on with markers, pens, and pencils, and are noted as compatible with laser, inkjet, and offset printing methods.
Larger cards (for example, 5 x 8 inches) provide noticeably more room for detailed notes or for early writers, while ruled fronts help keep writing clean and efficient.
