How the conversion works
A pixel has no fixed physical size. It only becomes a length once you say how many pixels fit in one inch — the DPI, or PPI. Multiply the inches by it to get pixels.
Strictly, DPI counts a printer's ink dots and PPI counts screen or image pixels, but for this arithmetic they are the same number.
pixels = inches × DPIWorked examples
- 8.5 in × 300 DPI = 2,550 px
- 20 in × 96 DPI = 1,920 px
- 3.5 in × 600 DPI = 2,100 px
Choosing a DPI
- 72 dpi
- Legacy screens & PDF points
- Older Mac displays and the PostScript / PDF point, where 72 points make one inch.
- 96 dpi
- Standard screens
- The default for web and Windows. One CSS pixel is defined as 1/96 of an inch.
- 150 dpi
- Draft prints
- Proofs and large posters that are viewed from a distance.
- 300 dpi
- Standard print
- Photos, flyers, brochures and documents. The usual target for print-ready files.
- 600 dpi
- High-quality print
- Fine line art, small text and detailed illustrations.
About this calculator
Type a size in inches, choose a DPI, and the pixel count appears as you type. There is no page reload and no account. For a two-dimensional size such as a page or a photo, use the 2-D canvas tab to convert width and height together, or pick a standard size from the Quick picks tab.
The math is one multiplication: pixels equal inches times DPI. A 1 inch square is 96 pixels at 96 DPI and 300 pixels at 300 DPI. A pixel has no fixed physical size on its own, so the DPI is what ties a digital size to a physical one. That is why the calculator asks for both numbers rather than guessing a default.
Which DPI to start with
Use 96 for anything that stays on a screen, and 300 for print. Older Mac and PDF conventions use 72, drafts often use 150, and fine line art sometimes calls for 600. A US Letter page (8.5 × 11 in) at 300 DPI is 2,550 × 3,300 pixels. The DPI vs PPI guide explains how to choose and how to check that an image is large enough to print.
Pixel sizes for common print jobs
The reference tables above cover the measurements people look up most, from 0.25 to 48 inches, at five DPI values. For sizes that come with their own questions about bleed, margins or cropping, there is a dedicated page for each:
How input is handled
The calculator accepts thousands separators and rejects negative numbers, exponents and extra decimal points, with a message that says what to fix instead of a silent wrong answer. Results are rounded to a sensible number of decimals, and the copy button grabs exactly what is shown, ready to paste into a spec, a design tool or a printer's order form. To go the other direction, for example to see how large an image will print, use the pixels to inches converter.
If your source is a PDF, you can turn its pages into images with a PDF to JPG converter and then check that the pixel dimensions match your target print size. Every calculation runs in your browser, so nothing you type is sent to a server.
Frequently asked questions
Quick answers on DPI, formulas, and how the tool handles your numbers.
How do I convert inches to pixels?
Multiply the inches by the DPI (dots or pixels per inch): pixels = inches × DPI. For example, an 8.5 × 11 inch page at 300 DPI is 2,550 × 3,300 pixels, and 20 inches at 96 DPI is 1,920 pixels.
How many pixels in an inch?
It depends on the DPI: 1 inch is 96 pixels on a typical screen (96 DPI), 72 pixels under the legacy 72 DPI convention, and 300 pixels at standard print quality (300 DPI). Multiply 1 inch by whatever DPI your device or printer uses to get the exact figure.
What DPI should I use?
Use 96 for how sizes render on most screens (one CSS pixel is 1/96 of an inch), 72 for legacy Mac and PDF point conventions, 150 for draft prints, 300 for standard print quality, and 600 for high-quality print or fine line art. If you know the DPI or PPI of your target device or printer, enter it as a custom value.
Is DPI the same as PPI?
Strictly, PPI counts pixels per inch on a screen or image, while DPI counts ink dots per inch from a printer. For converting inches to pixels the arithmetic is identical, so this tool treats them as the same number.
How many pixels is 8.5 x 11 inches?
At 300 DPI, 8.5 × 11 inches is 2,550 × 3,300 pixels. At 150 DPI it is 1,275 × 1,650, and at 96 DPI (screen) it is 816 × 1,056.
How many pixels is 4x6 inches?
At 300 DPI, 4 × 6 inches is 1,200 × 1,800 pixels. At 150 DPI it is 600 × 900, and at 96 DPI it is 384 × 576.
How do I check whether my image is big enough to print?
Divide the image's width in pixels by the print width in inches. A 3,000 px wide image printed 10 inches wide is 300 pixels per inch, a sharp print; printed 20 inches wide it is 150, which looks softer up close.
Can I convert a width and height together?
Yes. Switch to the 2-D canvas tab to convert width and height at once. One DPI value applies to both dimensions.
Is anything I type sent to a server?
No. Every calculation runs in your browser. There is no account, and nothing you enter is uploaded or stored. The only thing saved on your device is your light or dark theme choice.
