# Why does an architectural scale have so many scales?

Contents

Because the scale of such drawings are often smaller than life-size, an architect’s scale features multiple units of length and proportional length increments. For accuracy and longevity, the material used should be dimensionally stable and durable.

## What is an architectural scale based on?

A scale is also a ruler used in drawing and measuring architectural and engineering plans. Architectural scales units are based on foot/inch dimensions. Floor plan drawings are usually drawn to the scale of 1/4″ = 1′-0″. For a very large plan, a scale of 1/8″ = 1′-0″ may be used.

## What is the difference between an architectural scale and an engineer scale?

Architect scales have numbers that run incrementally both from left to right and from right to left. A whole number or fraction to the left or right of the number line indicates the scale those numbers represent. Engineer scales have numbers that run incrementally from left to right.

## How do you calculate scale?

To scale an object to a smaller size, you simply divide each dimension by the required scale factor. For example, if you would like to apply a scale factor of 1:6 and the length of the item is 60 cm, you simply divide 60 / 6 = 10 cm to get the new dimension.

## What are the 4 drafting scales?

Scales used in drafting include the mechanical engineer’s scale, the civil engineer’s scale, the architect’s scale, and the metric scale. 1/32″, 1/16″, 1/8″, 1/4″, 3/8″, 3/4″, 1/2″, and 1″ units.

## What does a 1/2 scale mean?

Half scale is 1:2. It is helpful to think of this as one unit on the drawing equals two units on the object. … This means the drawing of the object is twice as large as the object itself. Designers use an enlarged scale, such as double scale, on objects that are too small to draw full size with any meaningful detail.
