1080 p corresponds approximately to 81 dpi.
Converting 1080 p to dpi involves understanding the relationship between pixel height and dots per inch. Since p in video resolution refers to pixel height, to find dpi, you divide the pixel count by the physical height in inches. For example, if the physical height is 13.33 inches, dpi = 1080 / 13.33 ≈ 81 dpi.
Introduction
The conversion from 1080 p to dpi is about translating pixel height into a density measurement, indicating how many pixels fit into an inch on a display or print. This helps in determining image sharpness, clarity, and quality for screens or printed media based on pixel count and physical size.

Conversion Formula
The formula to convert pixel height (p) to dpi is: dpi = pixel height / physical height in inches. This works because dpi measures how many pixels are packed into an inch. For example, if 1080 pixels are displayed over 13.33 inches, dpi = 1080 / 13.33 ≈ 81 dpi. The math involves dividing pixels by inches to get density.
Conversion Example
- Suppose you have a display that is 1920 pixels wide and physical width is 24 inches.
- Calculating dpi: 1920 / 24 = 80 dpi.
- For 720 p resolution with a height of 13.33 inches, dpi = 720 / 13.33 ≈ 54 dpi.
- For 1440 p display with height of 10 inches, dpi = 1440 / 10 = 144 dpi.
- For 900 p resolution over 15 inches, dpi = 900 / 15 = 60 dpi.

Conversion Definitions
“p” refers to pixel height in digital resolutions, representing the number of vertical pixels in an image or display, indicating the vertical resolution of a video or image, and affecting clarity and detail in visual media.
“dpi” stands for dots per inch, measuring the density of pixels or dots in a one-inch span, used in printing and display quality to determine sharpness and detail based on pixel count over physical size.
Conversion FAQs
How accurate is the dpi calculation when converting 1080 p to physical size?
The dpi calculation is approximate because it assumes a specific physical height, typically 13.33 inches, but actual sizes vary depending on the device or print medium. Variations in physical size will change the dpi result.
Can I use this conversion to determine the ideal screen size for 1080 p resolution?
This conversion helps estimate dpi at a given physical height but does not directly determine the ideal screen size. Screen size depends on user preferences and optimal viewing distance, not just pixel density.
What physical height should I use if I want a specific dpi for 1080 p resolution?
To achieve a certain dpi, divide the pixel height by the desired dpi: physical height in inches = pixel height / dpi. For instance, for 81 dpi with 1080 pixels, height = 1080 / 81 ≈ 13.33 inches.
Does changing the physical size of the display affect the dpi value?
Yes, increasing physical size while keeping pixel resolution the same decreases dpi, reducing pixel density; decreasing physical size increases dpi, making images appear sharper.
Is dpi the same for digital screens and printed images?
No, dpi in digital screens relates to pixel density on displays, while in printing, dpi measures the density of ink dots on paper. They are related but used in different contexts and have different implications for image quality.
