What is an Inches to Pixels converter?
An Inches to Pixels converter calculates the pixel value needed for a physical inch length at a selected PPI. It supports single values and complete width-by-height dimensions for photos, pages, and design canvases.
At 96 PPI, 1in equals 96px. At 300 PPI, the same inch requires 300px.
How to convert inches to pixels
- Enter an inch value, or choose Dimensions for width and height.
- Select 96 PPI for CSS, 300 for a common print target, or enter a custom density.
- Copy the exact result.
Dimensions mode also includes quick values for 4 × 6, 5 × 7, 8 × 10, and US Letter sizes. Selecting a size does not lock the PPI.
Inches to Pixels formula and example
Use this formula:
Pixels = Inches × PPIFor an 8.5-inch width at 300 PPI:
8.5 × 300 = 2550pxAn 8.5 × 11in page therefore becomes 2550 × 3300px at 300 PPI.
Common inches to pixels conversions
The interactive table uses the selected PPI. These common values compare web and print densities:
| Inches | 96 PPI | 150 PPI | 300 PPI |
|---|---|---|---|
| 1in | 96px | 150px | 300px |
| 2in | 192px | 300px | 600px |
| 4in | 384px | 600px | 1200px |
| 8in | 768px | 1200px | 2400px |
| 8.5in | 816px | 1275px | 2550px |
| 10in | 960px | 1500px | 3000px |
| 11in | 1056px | 1650px | 3300px |
CSS inches and image pixels
CSS defines 1in = 96px, so 96 PPI is the correct reference for converting CSS absolute units. A CSS inch does not necessarily measure as one physical inch on every screen.
For an image or print design, choose the target PPI instead. The printer, publisher, or production workflow may specify the required value.
Photo and page dimensions
Dimensions mode keeps each unit together as width and height. Common inch presets fill the inch panel, after which the pixel result updates at the current PPI.
For example, a 4 × 6in photo needs 1200 × 1800px at 300 PPI. The converter does not crop, rotate, resize, or export the image itself.
PPI vs. DPI
PPI is pixels per inch and is used in the formula. DPI is dots per inch and normally refers to printer output. Print requirements may call a target “300 DPI,” but the image-dimension calculation is based on pixels per inch.

Inches to Pixels FAQ
How many pixels are in one inch?
One inch equals the selected PPI: 96px at 96 PPI, 150px at 150 PPI, or 300px at 300 PPI.
How many pixels is an 8.5 × 11-inch page?
It is 816 × 1056px at 96 PPI and 2550 × 3300px at 300 PPI.
How many pixels is a 4 × 6-inch photo?
At 300 PPI, it is 1200 × 1800px.
What PPI should I use for printing?
300 PPI is a common target for detailed, close-viewed print work, but the production provider’s specification should take priority.
Is DPI the same as PPI?
No. PPI measures image pixels per inch, while DPI usually measures printer dots per inch.
Does this converter resize an image?
No. It only calculates the pixel dimensions required for the selected physical size and PPI.
