What is a Pixels to Inches converter?
A Pixels to Inches converter calculates a physical inch length from a pixel value at a selected PPI. It can convert one value or the width and height of an image.
The same pixel dimensions produce different inch sizes at different densities. For example, 1920px equals 20in at 96 PPI but only 6.4in at 300 PPI.
How to convert pixels to inches
- Enter a pixel value, or select Dimensions for an image width and height.
- Choose 96 PPI for CSS, 300 for a common print target, or enter another density.
- Compare, copy, or export the converted result.
Both panels are editable. The swap control changes which unit is emphasized without changing the page or navigating away.
Pixels to Inches formula and example
Use this formula:
Inches = Pixels ÷ PPIFor 1920 pixels at 300 PPI:
1920 ÷ 300 = 6.4inAt 96 PPI, the same pixel value equals 20in.
Common pixels to inches conversions
The table in the converter follows the current PPI. This comparison includes common screen and image values:
| Pixels | 96 PPI | 150 PPI | 300 PPI |
|---|---|---|---|
| 96px | 1in | 0.64in | 0.32in |
| 300px | 3.125in | 2in | 1in |
| 600px | 6.25in | 4in | 2in |
| 1080px | 11.25in | 7.2in | 3.6in |
| 1920px | 20in | 12.8in | 6.4in |
CSS pixels vs. physical inches
CSS defines a fixed unit relationship of 1in = 96px. This makes 96 the correct reference when converting CSS px and in values.
It does not guarantee that 96 CSS pixels will measure exactly one physical inch on every display. Browser zoom, system scaling, and device density affect the size seen on screen. Use the target image PPI for print calculations.
Image dimensions and print size
Dimensions mode converts width and height together. At 300 PPI, a 1920 × 1080px image has a calculated print size of 6.4 × 3.6in.
The 96 vs 300 PPI comparison in the converter makes this difference visible without changing the selected PPI. No image is resized or resampled.
PPI vs. DPI
PPI means pixels per inch and connects pixel dimensions to physical inches. DPI means printer dots per inch. They are related in print discussions but describe different things; this converter performs its math with PPI.

Pixels to Inches FAQ
How many pixels are in one inch?
It depends on PPI. One inch contains 96 pixels at 96 PPI and 300 pixels at 300 PPI.
What is 1920 × 1080 pixels in inches?
At 96 PPI it is 20 × 11.25in. At 300 PPI it is 6.4 × 3.6in.
Can I convert pixels to inches without knowing PPI?
Only by assuming a density. Use 96 PPI for CSS or enter the target PPI for an image or print job.
Why do I get different inch sizes at 96 and 300 PPI?
At 300 PPI, more pixels fit into each inch, so the same image occupies less physical space.
Does 96 pixels always measure one physical inch on screen?
No. It is the CSS unit relationship, not a guarantee about the physical measurement of every display.
Does this converter change image resolution?
No. It calculates a size from numbers and does not modify an image.
