Standard Guide for Selection of Scales for Metric Building Drawings

SCOPE
1.1 This guide specifies recommended scales for architectural, building product, and building drawings using metric (SI) units of measurement, and measured with scale instruments graduated in millimetres. Preferred scales are listed for various types of drawings.

Standard Guide for
Selection of Scales for Metric Building Drawings
This standard is issued under the fixed designation E 713; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the Department of Defense.

INTRODUCTION
When metric (SI) units are used in building design and construction, the need arises to show metric
drawings in decimally compatible scale ratios to facilitate their production and interpretation with
decimally graduated scale instruments.
This guide responds to that need by recommending a range of preferred scales for different types
of building drawings.
