The size of 1080 corresponds to 15 inches when converted using the standard pixel-per-inch ratio of 72 PPI. This means that an image or display sized 1080 pixels wide measures about 15 inches across.
The conversion from size (in pixels) to inches depends on the resolution or pixels per inch (PPI). Assuming a common PPI of 72, dividing 1080 pixels by 72 gives the inch measurement. This method helps to relate digital dimensions to physical size.

Conversion Formula
The formula to convert size (in pixels) to inches is:
Inches = Size (pixels) ÷ Pixels Per Inch (PPI)
This works because pixels per inch tells how many pixels fit in one inch physically. If a screen or image has 72 pixels per inch, dividing total pixels by 72 gives how many inches the size occupies.
Example calculation for 1080 size:
- Given size: 1080 pixels
- PPI: 72 pixels per inch
- Calculation: 1080 ÷ 72 = 15 inches
- Result: 1080 pixels equals 15 inches physically
Conversion Example
- Convert 900 size to inches:
- Divide 900 by 72 PPI
- 900 ÷ 72 = 12.5 inches
- So, 900 pixels equals 12.5 inches
- Convert 1440 size to inches:
- Divide 1440 by 72
- 1440 ÷ 72 = 20 inches
- Therefore, 1440 pixels equals 20 inches
- Convert 720 size to inches:
- 720 ÷ 72 = 10 inches
- Hence, 720 pixels is 10 inches
- Convert 108 size to inches:
- 108 ÷ 72 = 1.5 inches
- So, 108 pixels equals 1.5 inches

Conversion Definitions
Size: Size in digital context is a numeric measure of length, width, or height expressed in pixels. It represents the number of pixels used to display or print an image or screen content, which correlates to physical dimensions based on resolution.
Inches: Inches are a unit of length in the imperial system, equal to 1/12 of a foot. It is commonly used in measuring physical sizes of objects like screens, paper, and other materials. One inch equals 2.54 centimeters exactly.
Conversion FAQs
What happens if the PPI value changes when converting size to inches?
If the pixels per inch value changes, the calculated physical size in inches will differ. A higher PPI means more pixels fit in one inch, so the same pixel size will result smaller inches, and vice versa for lower PPI.
Can I convert size to inches without knowing the PPI?
No, converting pixels to inches requires knowing the PPI because pixels alone do not have a fixed physical size. Without PPI, the conversion can’t be accurately done as physical size depends on pixel density.
Is the conversion the same for all screens and printers?
No, different screens and printers have different PPI values. A 1080 pixel image will measure differently on a 72 PPI screen versus a 300 PPI printer. Always use the correct PPI for the device to get accurate inch measurements.
Why is 72 PPI used often in pixel to inch conversions?
72 PPI was historically the standard screen resolution for many displays and is used as a baseline for conversion simplicity. However, modern screens often have higher PPI, so 72 PPI conversions might not reflect true physical size.
How does changing resolution affect the size in inches?
Changing the resolution (PPI) changes how pixels are mapped to physical size. Increasing resolution packs more pixels per inch, making images smaller in inches, while decreasing resolution spreads pixels out, increasing physical size.
