Pad paper, also called legal pad, notepad, writing pad, notebook, or memo pad, is a type of stationery that is used for taking notes, writing down reminders, or jotting down ideas. These pads come in various sizes and formats, including flip-top pads, spiral-bound pads, and glue-bound pads. Legal pads are often yellow with blue lines, while notepads can be plain white paper or colored sheets. Writing pads are similar in size to a legal pad but may include decorative designs or covers, while notebooks are usually smaller, portable and have a binding. Memo pads are typically smaller and used for quick notes or messages. Regardless of the synonym used, pad paper is a useful item to have on hand in any work or study environment.
