- The ratio comparing the dimensions of a drawing or model to the actual dimensions of the real object.
- Scale factor
- The number used to multiply original dimensions to enlarge or reduce them proportionally.
- 1 : 1
- Full size (life size); the drawing matches the real object's actual size, such as a blueprint of a phone screen.
- 1 : 2
- Half size; 1 cm on the drawing equals 2 cm in reality, common in tabletop sketches or small craft patterns.
- 1 : 10
- Reduction where 1 cm represents 10 cm; often used for detailed furniture designs and RC toy cars.
- 1 : 50
- Reduction where 1 cm represents 50 cm (0.5 m); standard for detailed architectural floor plans of individual rooms.
- 1 : 100
- Reduction where 1 cm equals 100 cm (1 metre); typical for whole-house architectural blueprints.
- 1 : 500
- Reduction where 1 cm represents 5 metres; commonly used for site plans showing a house and garden boundary.
- 1 : 1,000
- Reduction where 1 cm represents 10 metres; used for school campus layouts and park planning.

- Enlargement where 10 cm represents 1 cm; common in biological diagrams of insects or flower parts.
- 100 : 1
- Major enlargement where 1 mm represents 0.01 mm; used for diagrams of microscopic cells and bacteria.
- Representative Fraction (RF)
- A scale written as a fraction or ratio without units, meaning both sides share the same measurement unit.
- Word scale
- A scale expressed with units, such as '1 cm represents 5 km', commonly found on driving maps.
- Bar scale (linear scale)
- A marked line resembling a ruler on a map that shows real-world ground distances visually.
