Use our free Pixel Aspect Ratio (PAR) calculator to accurately determine the PAR of your digital images or videos. Avoid common display issues like stretching or squeezing by understanding how pixel dimensions relate to your target screen's aspect ratio. Essential for video editors, graphic designers, and web developers looking for optimal visual quality.
Formula:
The Pixel Aspect Ratio (PAR) is determined by comparing the Display Aspect Ratio (DAR) with the Storage Aspect Ratio (SAR) of your media.
Formula: PAR = (DAR_Width / DAR_Height) / (Pixel_Width / Pixel_Height)
This can be simplified to:PAR = (DAR_Width × Pixel_Height) / (DAR_Height × Pixel_Width)
Where:
- DAR_Width: The width component of your target display's aspect ratio (e.g., 16 for 16:9).
- DAR_Height: The height component of your target display's aspect ratio (e.g., 9 for 16:9).
- Pixel_Width: The width of your image/video in pixels.
- Pixel_Height: The height of your image/video in pixels.
