How to Read an Architect Scale

Master the fundamentals of scale drawing with this easy-to-follow guide designed for middle and high school students. Learn how to use ratios, proportions, rulers, and graph paper to create accurate scale representations of objects, rooms, and real-world designs. Perfect for STEM, art, and technical drawing lessons.
Orthographic Basics
Orthographic Projection
​Objective: To equip students with the ability to create and interpret scale drawings by applying mathematical principles of ratio and proportion, enhancing their skills in spatial reasoning, measurement, and real-world technical applications in engineering, architecture, and design.
Full Scale means 1 inch drawn on paper represents 1 inch in real life. Full scale is the same size in real life as on paper.

Half Scale means 1 inch drawn on paper equals 2 inches in real life. Half scale is everything drawn half the size of the object in real life.
