DPI to Pixel Size Calculator
Convert a physical print size and DPI into the required pixel dimension.
How to use DPI to Pixel Size Calculator
1. Enter Physical Size Inches, DPI. 2. Use inches. The DPI tool treats the entered density numerically; printer dots and image pixels are not interchangeable device guarantees. 3. Select Calculate or press Enter. 4. Select Copy result to copy the answer, or Reset to clear the form and result.
Why use this tool?
Use inches. The DPI tool treats the entered density numerically; printer dots and image pixels are not interchangeable device guarantees.
How the calculation works
Required pixels or dots = physical inches × entered per-inch density, rounded to a whole count. Use inches. The DPI tool treats the entered density numerically; printer dots and image pixels are not interchangeable device guarantees. Counts and dimensions use the declared rounding convention; other numbers display up to three decimal places where applicable. Nonzero subsecond durations are labelled. Durations round to the nearest second; nonzero subsecond durations are labelled. File-size output units are decimal. Changing an input label does not convert filled values.
Example
Worked example: Physical Size Inches = 10; DPI = 300. Result: 3000 px.
Practical tip
Check the input labels and assumptions against the dpi to pixel size task before reusing the number.
