- 尺寸比计算器 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, 黄金比例 calculations, and resizing objects while maintaining proportions.
Formula of Dimension Ratio Calculator
计算公式 dimension ratio for two-dimensional objects is:
Dimension Ratio = (Longer Dimension) / (Shorter Dimension)
其中：
- 长度 is the longest side of the object.
- 宽度 is the shorter side of the object.
对于 三维物体，公式扩展为：
Dimension Ratio = Length : Width : Height
常见应用：
- 屏幕宽高比: The ratio of width to height in displays.
- 计费示例： 16:9 (common for TVs and monitors).
- 设计中的黄金比例: Aesthetic ratio of 1.618, often found in art, architecture, and nature.
- Paper Size Ratio: Standard paper sizes, such as A4，遵循 √2 ratio to maintain proportions when resized.
General Dimension Ratio Table
The table below provides common dimension ratios used in different applications:
| 应用领域 | Dimension Ratio Example | 常见用例 |
|---|---|---|
| 屏幕宽高比 | 16:9, 4:3, 21:9 | TV, Computer Monitors, Phones |
| 黄金比例 | 1:1.618 | Art, Architecture, Web Design |
| Paper Size Ratio | 1：√2 | A4, A3, A5 Paper Standards |
| 图像大小调整 | 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
假设一个 屏幕 宽度为 1920像素 高度为 1080像素. 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.
对于 框 有尺寸 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 部分。
最常见的常见问题解答
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.
- 16：9宽高比 is the most common for TVs, monitors, and smartphones, providing a widescreen viewing experience.
