720 pixels is equal to 10 inches.
The conversion from pixels to inches depends on the pixel density or resolution, commonly measured in pixels per inch (PPI). Assuming a standard screen resolution of 72 PPI, dividing the number of pixels by 72 gives the equivalent length in inches.

Conversion Formula
The formula to convert pixels to inches is inches = pixels ÷ PPI. PPI stands for pixels per inch, which is the count of pixels in one inch on a display or image. By dividing the total pixels by the PPI, it gives how many inches those pixels cover in real size.
For example, with a standard 72 PPI screen:
- Pixels = 720
- PPI = 72
- Inches = 720 ÷ 72 = 10 inches
This means 720 pixels span 10 inches on a device displaying at 72 pixels per inch resolution.
Conversion Example
- Convert 360 pixels to inches:
- Divide 360 by 72 (the PPI): 360 ÷ 72 = 5 inches.
- This means 360 pixels equal 5 inches on a 72 PPI display.
- Convert 1440 pixels to inches:
- 1440 ÷ 72 = 20 inches.
- So 1440 pixels measure 20 inches wide.
- Convert 100 pixels to inches:
- 100 ÷ 72 ≈ 1.3889 inches.
- Therefore, 100 pixels is roughly 1.39 inches long.
- Convert 50 pixels to inches:
- 50 ÷ 72 ≈ 0.6944 inches.
- Hence, 50 pixels equals about 0.69 inches.

Conversion Definitions
Pixels: A pixel is the smallest unit of a digital image or display, representing a single point of color. Pixels compose the images seen on screens, and their density per inch (PPI) determines the resolution and clarity of the display or image.
Inches: An inch is a unit of length in the imperial system, equal to 2.54 centimeters. Inches are used broadly for measuring physical objects and dimensions, including print sizes and display measurements for screens and images.
Conversion FAQs
Does pixel density affect how many inches 720 pixels measure?
Yes, pixel density (PPI) changes the physical size that 720 pixels represents. A higher PPI means more pixels packed into each inch, making 720 pixels cover a smaller physical length. Conversely, lower PPI stretches those pixels over more inches.
Can 720 pixels equal different inch values on different devices?
It can, because devices may use different PPI settings. For example, a phone screen with 300 PPI will show 720 pixels in a much smaller physical size than a monitor at 72 PPI. The conversion depends on the device’s pixel density.
Is the conversion formula the same for print and digital screens?
The formula is similar but the PPI values differ. Digital screens have a PPI based on their resolution and size, while printed images use DPI (dots per inch) which affects print size. So 720 pixels in digital may not equal the same inch length in print.
Why using 72 PPI is common for pixel to inch conversion?
Historically, 72 PPI was standard on many displays and design software, making it a default reference. However, many modern screens have higher PPI, so the real inch size can vary. 72 PPI remains a simple standard for estimation.
How accurate is converting pixels to inches using a fixed PPI?
Using a fixed PPI provides an estimate but may not be precise for all devices. Actual pixel density changes with screen type, zoom level, and settings. For exact physical size, the device’s real PPI must be known and used in the conversion.
