Pixel Aspect Ratio Calculator
Pixel Aspect Ratio (PAR):
A Pixel Aspect Ratio (PAR) table can be useful for understanding how different pixel aspect ratios affect the display of images and videos. Pixel aspect ratio refers to the shape of individual pixels and can affect how content is displayed. Here’s a table that covers common pixel aspect ratios:
Pixel Aspect Ratio | Description | Common Use Cases |
---|---|---|
1:1 | Square pixels | Standard for most displays |
4:3 | Non-square (slightly taller) | Older SD TV formats |
16:9 | Non-square (wider) | Widescreen HD and UHD displays |
2:1 | Non-square (wider) | Anamorphic widescreen |
21:9 | Non-square (much wider) | Ultra-wide displays |
9:16 | Non-square (taller) | Portrait mode in smartphones |
Custom | Varied pixel aspect ratios | Specialized applications |
- 1:1 Pixel Aspect Ratio: Square pixels are the standard and most common. Each pixel is equally wide and tall, resulting in a uniform grid. This is the default for most digital displays.
- 4:3 Pixel Aspect Ratio: Pixels are slightly taller than they are wide. This aspect ratio was prevalent in older standard-definition (SD) television formats.
- 16:9 Pixel Aspect Ratio: Pixels are wider than they are tall. This aspect ratio is typical for widescreen high-definition (HD) and ultra-high-definition (UHD) displays.
- 2:1 Pixel Aspect Ratio: Pixels are much wider than they are tall. This aspect ratio is used in anamorphic widescreen formats, often in filmmaking.
- 21:9 Pixel Aspect Ratio: Pixels are significantly wider than they are tall, creating an ultra-wide display format. Commonly found in ultra-wide computer monitors and cinema screens.
- 9:16 Pixel Aspect Ratio: Pixels are taller than they are wide, suitable for portrait mode in smartphones and other mobile devices.
- Custom Pixel Aspect Ratio: In some specialized applications, custom pixel aspect ratios are used to achieve specific artistic or technical effects.
Understanding pixel aspect ratios is important when dealing with content creation and display, as it can affect how images and videos appear on different screens and devices.
FAQs
- How do you calculate aspect ratio with pixels?
- Aspect ratio is calculated by dividing the width of an image or screen by its height. For example, for an image with dimensions 1920×1080 pixels, the aspect ratio would be 16:9 (1920 divided by 1080).
- What is the pixel aspect ratio?
- Pixel aspect ratio refers to the shape of individual pixels in a display. It’s typically 1:1, meaning pixels are square. In some cases, it can be non-square, but this is less common.
- What aspect ratio is 1920×1080?
- The aspect ratio of 1920×1080 is approximately 16:9.

- How do I calculate aspect ratio?
- To calculate the aspect ratio, divide the width by the height of an image or screen.
- Is aspect ratio the same as pixel size?
- No, aspect ratio and pixel size are not the same. Aspect ratio describes the proportional relationship between width and height, while pixel size refers to the physical size of individual pixels on a display.
- What is 1920×1080 pixel format?
