Interior design drawings contain huge amounts of information that is needed for other people involved in the project such as consultants, contractors, and builders. But all the information needed is hard to be illustrated effectively on the actual drawings. Some information is best communicated in the form of specifications, and other information in schedules.
A schedule refers to a tabular form with rows and columns of data to effectively organize information. Schedules deliver deeper information than can be shown on the actual drawings, but not as deep information as in specifications. Schedules must be clear and easy to read. Although the format of schedules may vary among design firms, typical schedules are drawn in grid lines spaced either 3/16 or 1/4 inch apart, but no less than 3/16 inch for readability. The height of lettering is either 3/32 or 1/8 inch.
