# What Is a Scale?

A scale is a ratio that reduces the size of an object, such as a mountain or a building. It can also help us draw accurate models or work with drawings that fit on standard sizes of paper.

The aim of this article is to serve as a primer for those interested in scale development. Specifically, it covers six specific steps to creating a scale.

## Definition

A ratio of the dimensions of a model or drawing to those of an actual figure, often expressed as a fraction. Also called scale factor and scale.

#### Music and Dance

A succession of tones ascending or descending according to fixed intervals, esp. one involving whole steps or semitones: C-E; Do-re-mi-fa-sol-la-ti-do.

#### Mathematical

The relative size of something: a scale model; the scale of the earth: the ratio of distances to areas in a map. Also used in the sense of a graduated range: a scale of values; the scale of fees for services rendered.

#### Physics

Madame Blavatsky believed that the physical laws governing matter are not the same at all levels of existence, but change in scale. This is what she meant by the principle of the’scale dimension’. This is why the time axis of spacetime is not identical to the spatial axes. It is also why the power of gravity is different at a particular level of matter than at another.

## Functions

The function scale() takes two values, one for each dimension. When both values are equal the element is unchanged (isotropic). If one value is larger than the other, the graph is stretched, and if it is smaller, it is shrunk.

In music, a scale is a graduated sequence of notes, tones, or intervals dividing what is called an octave. Its functions vary from culture to culture, and are often a pre-existent assumption for the composer or performer.

Our Scale Functions are thread-safe by default, have cold-start times of less than 100 microseconds, and incur next to zero overhead when calling them. They also support a number of programming languages, including rust, golang, and typescript. You can even chain them together into pipelines, using our Scale Registry, to create powerful applications at scale. You can learn more about this new way to deploy business logic by visiting our docs.

## Examples

Many different types of scales are used in a variety of contexts. For example, the grading system in a school may be described as a ’10 point scale’ or a person’s performance on a project might be evaluated using a ‘Nice to Good’ scale.

Another use of scale involves the dimensions of a map. Cartographers use a scale factor to represent the ratio between map units. This allows people to easily interpret map data from unfamiliar locations.

Artists can also leverage the concept of scale to create interesting effects in their work. For example, Pakistani-born artist Shahzia Sikander is interested in exploring the relationship that humans have with size in space through her miniature paintings. These works are based on the tradition of medieval manuscript illuminations and other art forms, including Persian miniatures that often represented religious themes or mythological stories. She uses scale to re-proportion the symbolic meanings that such images already have. Reviewers have complimented the design and functionality of this scale, with one purchaser stating that “it is a beautiful product and very easy to operate.” Multiple reviewers agree that the display automatically recalibrates after each use, eliminating the need to tap on it with your foot or other object to get an accurate read.

## Applications

Scaling up enables businesses to meet the needs of their customers. It also increases revenue potential by opening new markets and exploring untapped demographics. For example, Walmart grew from a small regional retailer to the world’s largest retail business by expanding its product offerings and targeting different customer segments. Scaling up also diversifies income sources and reduces reliance on a single market or customer segment, which can be beneficial in times of economic uncertainty or industry disruption.

In software, app scaling involves adding resources to an application so that it can handle high traffic or peak usage periods. This may include adding faster processors or more memory to servers that run the application, or it may involve deploying the app in datacenters around the world to ensure low latency for users. It is important for developers to carefully evaluate their application’s current and projected growth rates, peak usage periods, and scale requirements before beginning the process.
