A scale drawing is used to reduce the amount of paper it
would take, to draw a large object. The picture below provides you with
an excellent example of a stairway that was designed as a scale drawing.
Scale drawings provide additional information for stair builders and
construction workers.

Usually a scale drawing is represented by a scale
measurement. For example, a quarter of an inch can represent 1 foot. If
this was the case and you measured a 2 inch stairway on a scaled
drawing, the 2 inches would represent 8 feet.
Each inch would represent 4 feet on a 1/4 inch = 1 foot scale.
Each inch would represent 2 feet on a 1/2 inch = 1 foot scale.
Each inch would represent 1 foot on a 1 inch = 1 foot scale
These drawings are often provided by architects, engineers and building
designers and can use different scales, to accomplish different tasks.
If you were designing a 100 foot stairway, you might need to use 1/16 of
an inch or 1/8 of an inch scale drawing, just to fit on one piece of
paper.
