3 inches is equal to 360 pixels.
Table of Contents
This conversion assumes a standard resolution of 120 pixels per inch (PPI). Since one inch equals 120 pixels, multiplying 3 inches by 120 gives the pixel value.

Conversion Formula
The formula to convert inches to pixels is:
pixels = inches × pixels per inch (PPI)
Pixels per inch (PPI) is the number of pixels contained in one inch of a digital display or image. Without specifying PPI, the conversion cannot be exact. Here, we’re using 120 PPI, a common value for some screens.
Step-by-step for converting 3 inches:
- Start with: 3 inches
- Multiply by 120 PPI: 3 × 120
- Result: 360 pixels
Conversion Example
- Convert 5 inches to pixels:
- Multiply 5 by 120 (PPI), we get 600 pixels.
- So, 5 inches equals 600 pixels.
- Convert 0.75 inches to pixels:
- 0.75 × 120 = 90 pixels.
- This means 0.75 inches corresponds to 90 pixels.
- Convert 10 inches to pixels:
- 10 × 120 = 1200 pixels.
- 10 inches is 1200 pixels in length.

Conversion Definitions
Inches: Inches is a unit of length in the imperial system, equal to 1/12 of a foot or 2.54 centimeters. It is commonly used in the United States and some other countries for measuring height, width, and distance in everyday applications, including screen sizes and paper dimensions.
Pixels: Pixels are the smallest individual elements in a digital image or display. A pixel represents a single point in a raster image, and collectively pixels form the images we see on screens. The number of pixels per inch affects the image clarity and detail.
Conversion FAQs
Why use 120 pixels per inch for conversion?
The 120 PPI value is chosen here as an example representing some screen resolutions. Different devices have varying pixel densities, so 120 PPI is a round figure that helps illustrate the calculation. If you know your device’s exact PPI, use that instead for accuracy.
Does the inch to pixel conversion change based on device?
Yes, because pixels are physical dots on a screen, the actual size of a pixel can vary depending on screen density (PPI). Two devices showing the same pixel count may display different physical sizes. That’s why specifying PPI is necessary for accurate conversion.
Can I convert pixels back to inches?
Yes, by dividing the pixel value by the pixels per inch. For example, if you have 360 pixels and your device is 120 PPI, the length in inches is 360 ÷ 120 = 3 inches. It’s the inverse of the inches to pixels conversion.
Is the conversion affected by screen resolution settings?
Screen resolution impacts how many pixels fit in an inch on the display. Higher resolution means more pixels per inch, which leads to smaller pixels and sharper images. Changing resolution changes the PPI value and thus conversion results.
What if I need a more precise conversion for printing?
Printing often uses dots per inch (DPI) rather than pixels per inch. While related, DPI involves printer dots, which isn’t the same as screen pixels. For printing, use the printer’s DPI setting to convert inches to dots instead of pixels.
