DPI to Pixel Converter
Convert DPI to pixels and image size to print size in inches, cm, and mm.
Loading tool…
DPI to Pixel Converter answers three questions that come up when preparing images for print: what a given DPI looks like per inch, centimetre, or millimetre; how many pixels an inch of output needs at your chosen DPI; and how large a pixel image will actually print at that resolution. This is not the Android dp unit, which follows screen density instead and has its own converter here.
How to use
- Choose what to calculate: DPI per unit, inches to pixels, or image size to print size.
- Enter the number and, where asked, the DPI.
- Read the pixels or the print measurement.
Features and limitations
- Three modes in one panel: DPI per physical unit, inches to pixels, and image size to print size.
- Millimetres and centimetres are handled alongside inches, which is what a print order in Indonesia usually uses.
- The same DPI set appears as a pencil-weight scale, so a designer can read the result in familiar terms.
- It says plainly that dpi is not dp, because the two get confused constantly.
Limitation: Uses the CSS screen standard of 96 dpi per inch unless you change the number. Print resolution is a separate measurement, and this does not read the DPI embedded in your own image files.

Frequently asked questions
Usage, result, and limitation information for this tool.
- Is dpi the same as dp on Android?
- No, and the difference matters. dp follows screen density so that a layout looks the same physical size across devices. dpi is print resolution, and 300 dpi is a statement about ink, not about screen size.
- Why is 96 the default?
- It is the CSS reference pixel density, which is what browsers assume when a specification does not say otherwise. A design file exported for screens is usually built on that assumption.
- Does it read the DPI in my image file?
- No. It calculates. The DPI tag stored inside a JPEG tells you what the file claims, which is often wrong, and reading it is a separate job from converting a number.
- A 1920 pixel wide image, how big does it print at 300 dpi?
- 6.4 inches, which is 16.26 cm. The converter shows that directly, along with the same figure at 72 dpi for comparison.
