How to convert inches to pixels

To convert inches to pixels, you have to multiply inches by resolution. For example, a 4 inches wide object scanned at 300 DPI will have 1200 pixels on a computer screen. Most scanners allow you to change the DPI resolution from the software. If the scanned object is printed, then you have to scan it at the same resolution as the printer’s resolution.

    Interesting but it doesn’t really help for designing something online to put on a wooden sign that has dimensions of about 9″W x 48″L

    It would be better if it was obvious where the measure to find your PDI is, other than that it was helpful.

    Why is it assumed that there is a scanner involved? I wanted to convert inches to pixels for a legacy web page that need some work and I just wanted to be consistent with the units used throughout the site. I worked around the issue by selecting a custom dpi of 72 which is the usual standard for screens. I suggest you allow the user to choose between Scanner and Screen conversions.

    • You’re right Julio. It does not have to be a scanner involved. The converter can work for any purpose that involves inches to pixels conversions.
