2.5 inches is equal to 240 pixels.
The conversion from inches to pixels depends on the DPI (dots per inch) setting, which commonly is 96 DPI for screens. Multiplying 2.5 inches by 96 pixels per inch gives the pixel value.

Conversion Formula
The formula to convert inches to pixels is: pixels = inches × DPI. DPI, or dots per inch, represent how many pixels fit in one inch on a screen. Most screens use 96 DPI, so to get pixels, you multiply the inch value by 96.
It works by scaling the physical length (inch) to the digital representation (pixels) according to screen resolution. For example:
- Given 2.5 inches and DPI of 96
- Multiply: 2.5 × 96 = 240 pixels
- The pixel length corresponds to 240 pixels on the screen
Conversion Example
- Convert 4 inches to pixels:
- Multiply 4 × 96
- Equals 384 pixels
- So, 4 inches is 384 pixels
- Convert 1.75 inches to pixels:
- Multiply 1.75 × 96
- Equals 168 pixels
- Hence, 1.75 inches equals 168 pixels
- Convert 0.5 inches to pixels:
- Multiply 0.5 × 96
- Equals 48 pixels
- Therefore, half an inch is 48 pixels

Conversion Definitions
Inches: An inch is a unit of length commonly used in the United States and other countries, equal to 1/12 of a foot or exactly 2.54 centimeters. Inches measure physical dimensions such as screen size, paper, or objects.
Pixels: A pixel is the smallest unit of a digital image or display, representing a single point in a raster image. Pixels compose images on screens, and their size depends on screen resolution and density.
Conversion FAQs
Why does the DPI value affect the inch to pixel conversion?
DPI stands for dots per inch, it defines how many pixels fit into one inch physically. Different devices have different DPI, so the same inch measurement can result in different pixel counts depending on the DPI used for conversion.
Can I convert inches to pixels without knowing the DPI?
Without DPI, you can’t accurately convert inches to pixels. DPI acts like the scale between physical size and digital pixels. Using a default DPI like 96 gives an estimate but might not match every device’s actual pixel density.
How do different screen resolutions affect pixel size from inches?
Higher screen resolution means more pixels per inch, so a length in inches will translate into a larger pixel number. Lower resolution means fewer pixels per inch, causing fewer pixels for the same physical length.
Does printer DPI influence inches to pixels conversion for screens?
Printer DPI is different from screen DPI, because printers use dots of ink and screens use pixels. Inches to pixels conversion for digital screens should use screen DPI, not printer DPI, to get correct pixel values.
Is the conversion formula valid for all digital devices?
The formula works where DPI or pixel density is known and consistent. Some modern devices vary pixel density across screens or use scaling factors, so simple multiplication may not give exact pixel size without considering these factors.
