900 pixels equals 12.5 inches.
The conversion from pixels to inches depends on the pixels per inch (PPI) value, which is often 72 or 96 in digital displays. Assuming a standard 72 PPI, 900 pixels divided by 72 gives 12.5 inches. This means that 900 pixels will take up 12.5 inches in physical size on a screen or print at that resolution.

Conversion Formula
The formula to convert pixels to inches is:
Inches = Pixels ÷ PPI
Where PPI means pixels per inch, the density of pixels in one inch of the display. The number of pixels divided by the pixel density gives the length in inches.
For example, if you have 900 pixels and the screen has 72 pixels per inch:
- Divide 900 pixels by 72 PPI
- 900 ÷ 72 = 12.5 inches
This is why 900 pixels corresponds to 12.5 inches at 72 PPI.
Conversion Example
- Convert 480 pixels to inches at 72 PPI
- Divide 480 by 72
- 480 ÷ 72 = 6.6667 inches
- Result: 480 pixels equals about 6.67 inches
- Convert 1200 pixels to inches at 72 PPI
- Divide 1200 by 72
- 1200 ÷ 72 = 16.6667 inches
- Result: 1200 pixels equals about 16.67 inches
- Convert 360 pixels to inches at 72 PPI
- Divide 360 by 72
- 360 ÷ 72 = 5 inches
- Result: 360 pixels equals 5 inches
- Convert 720 pixels to inches at 72 PPI
- Divide 720 by 72
- 720 ÷ 72 = 10 inches
- Result: 720 pixels equals 10 inches

Conversion Definitions
Pixels: Pixels are the smallest units of a digital image or display screen, representing a single point of color or brightness. They are the basic building blocks that composes images on devices, measured in count horizontally and vertically, not physical size.
Inches: Inches is a unit of length in the imperial measurement system, equal to 1/12 of a foot or 2.54 centimeters. It measures physical distances or sizes and is used to describe dimensions of objects, prints, or screens.
Conversion FAQs
What happens if the PPI value changes when converting pixels to inches?
If the pixels per inch (PPI) changes, the physical size in inches for the same pixel count will change too. A higher PPI means more pixels packed into each inch, so the length in inches gets smaller. Lower PPI means fewer pixels per inch, making the inch length larger.
Can I use the pixel to inch conversion for printed images?
You can use the conversion for printing, but the PPI for print, often called DPI, must be known. Prints usually have higher DPI (like 300), so 900 pixels divided by 300 DPI would give 3 inches, which is smaller than on a screen with 72 PPI.
Why does 900 pixels not always equal the same inches across devices?
Different devices have different pixel densities (PPI). A 900 pixel wide image on a monitor with 72 PPI will take more physical space than on a smartphone with 300 PPI. So, the inch measurement varies unless the pixel density is considered.
Is there a way to convert pixels to inches without knowing the PPI?
No, converting pixels to inches requires knowing the pixels per inch value. Pixels measure resolution, inches measure physical size; without the density linking them, conversion can’t be accurate.
How does browser zoom affect pixel to inch conversions?
Browser zoom changes how many pixels are displayed visually, but the device pixel ratio and PPI stay the same. So, zooming changes the apparent size on screen but not the actual pixel count or physical inch size in the conversion formula.
