96 pixels on the web
CSS defines 1 inch as 96 px, so web layouts, browser tools, and most online converters treat an inch as 96 pixels.
Inch and pixel conversion
Convert inches to pixels for print or screen. Enter a size in inches, pick a PPI, and get the exact pixel dimensions, with the 96 PPI and 300 PPI answers side by side.
Inches in
Height is optional. Switch the unit if your size is in centimeters.
Common PPI values
Common sizes in inches
Formula: pixels = inches × PPI.
Pixels out
The pixel dimensions needed to fill this size at the selected PPI.
As many as the PPI says. An inch has no built-in pixel count.
CSS defines 1 inch as 96 px, so web layouts, browser tools, and most online converters treat an inch as 96 pixels.
A print specification of 300 PPI means each printed inch needs 300 pixels. A 1 inch square at that density is 300 × 300 px.
Some design software and templates still assume 72 PPI. If a template says 72, an inch in that file is 72 pixels.
Multiply each side by the PPI, then round to whole pixels.
Take a 4 × 6 inch photo that a lab wants at 300 PPI. The width is 4 × 300 = 1200 px and the height is 6 × 300 = 1800 px, so the file should be at least 1200 × 1800 pixels.
For a screen layout the same 4 × 6 inches at 96 PPI is 384 × 576 px. The inch size is identical; the pixel requirement changes because the density changes.
If you already have an image and want to know whether it is large enough, check its pixel size with the Image Size Checker and compare it with the result above.
Common inch values converted to pixels at four densities, rounded to whole pixels.

Short answers for the most common sizes and densities.
There is no single answer: it equals the PPI. At 96 PPI, the CSS reference density, 1 inch is 96 pixels. At 72 PPI it is 72 pixels, and at 300 PPI, a common print density, it is 300 pixels.
Multiply the inches by the PPI. 4 inches at 300 PPI is 1200 pixels, and 4 inches at 96 PPI is 384 pixels.
2 inches is 192 pixels at 96 PPI, 144 pixels at 72 PPI, and 600 pixels at 300 PPI. A 2 x 2 inch photo at 300 PPI is 600 x 600 pixels.
A letter-size page of 8.5 x 11 inches is 816 x 1056 pixels at 96 PPI and 2550 x 3300 pixels at 300 PPI.
300 PPI is a common requirement for prints viewed up close. Larger prints seen from a distance can use less. If a printer or publisher gives a number, use theirs.
Open Image > Image Size and switch the width and height units to Pixels. With the units set to Inches, the Resolution field shows the PPI that links the two.
