An Aspect Ratio Calculator
Aspect Ratio Calculator Instructions
- Enter the values for the original width (W1) and original height (H1) on the left.
- Enter either a new width (W2) or new height (H2) on the right to calculate the remaining value.
- Change any of the values at any time, or reset them to the starting values.
W1 H1 | = | W2 H2 |
The calculated aspect ratio is: ? : ?
Aspect Ratio Calculation Mathematics Overview
The aspect ratio formula is width divided by height
ratio = width / height
To use this formula, the width and height should have the same units, resulting in an aspect ratio that has no units.
The word ratio goes back to Ancient Greece. The Latin translation of ratio means to be rationale or to reason. The reasoning pertains to understanding the relationship between two values.
The following is a real-life example of ratios:
A ratio is the comparison of two quantities of the same kind, or the relationship of one similar quantity to another. Ratios can be written in three different ways using ratio symbols or words, while keeping the same meaning. That is, ratios can be written by placing a fraction bar, the word "to", or the ratio symbol '' : '' between the two values being compared.
Different ratio symbols can be used to compare to values.
Ratio Symbols
Using the previous example of comparing the two groups of students in Ms. Jones' class, the ratio of ninth grade students to tenth grade students can take on any of the three following forms:
10 to 20
10 : 20
All three ways, written using different ratio symbols, compare the 10 ninth graders to the 20 tenth graders in the geometry class, and they all have the same meaning.

In mathematics, a superparticular ratio, also called a superparticular number or epimoric ratio, is the ratio of two consecutive integer numbers.
Superparticular ratios were written about by Nicomachus in his treatise Introduction to Arithmetic. Although these numbers have applications in modern pure mathematics, the areas of study that most frequently refer to the superparticular ratios by this name are music theory and the history of mathematics.
