A Calculadora de proporção de dimensão helps users determine the proportional relationship between two or more dimensions of an object. It is widely used in engineering, design, construction, and media industries where maintaining accurate proportions is essential.
This tool simplifies ratio calculations, making it easy to compare lengths, widths, and heights of objects while ensuring proper scaling for displays, architectural projects, and manufacturing processes. It is particularly useful for screen aspect ratios, proporção áurea calculations, and resizing objects while maintaining proportions.
Formula of Dimension Ratio Calculator
A fórmula para calcular o dimension ratio for two-dimensional objects is:
Dimension Ratio = (Longer Dimension) / (Shorter Dimension)
em que:
- Comprimento is the longest side of the object.
- Largura is the shorter side of the object.
Para a objetos tridimensionais, the formula extends to:
Dimension Ratio = Length : Width : Height
Aplicações comuns:
- Proporção da tela: The ratio of width to height in displays.
- Exemplo: 16:9 (common for TVs and monitors).
- Proporção Áurea em Design: Aesthetic ratio of 1.618, often found in art, architecture, and nature.
- Paper Size Ratio: Standard paper sizes, such as A4, siga um √2 ratio to maintain proportions when resized.
General Dimension Ratio Table
The table below provides common dimension ratios used in different applications:
| Solicitações | Dimension Ratio Example | Caso de uso comum |
|---|---|---|
| Proporção da tela | 16:9, 4:3, 21:9 | TV, Computer Monitors, Phones |
| Proporção áurea | 1:1.618 | Art, Architecture, Web Design |
| Paper Size Ratio | 1:√2 | A4, A3, A5 Paper Standards |
| Redimensionamento de Imagem | 3:2, 4:5, 1:1 | Photography, Printing |
| Box Proportions | 2:1:1, 1:1:1 | Packaging, Storage Boxes |
This table helps users quickly reference commonly used ratios in different industries.
Example of Dimension Ratio Calculator
Suponha que um tela tem uma largura de Pixels 1920 e uma altura de Pixels 1080. The aspect ratio is calculated as:
Dimension Ratio = Width / Height
= 1920 / 1080
= 16:9
This confirms that the screen follows the 16:9 standard aspect ratio.
Para uma caixa com dimensões 30 cm (length), 15 cm (width), and 10 cm (height), the dimension ratio is:
Dimension Ratio = Length : Width : Height
= 30:15:10
= 3:2:1
This means the box maintains a 3:2:1 proporção.
Perguntas frequentes mais comuns
The dimension ratio helps maintain proportional accuracy in designs, ensuring objects are scaled correctly without distortion.
To keep the aspect ratio the same, use the original width-to-height ratio and scale both dimensions proportionally.
A 16: 9 proporção is the most common for TVs, monitors, and smartphones, providing a widescreen viewing experience.
