How Do You Convert Inches to Pixels?
To convert inches to pixels, multiply the number of inches by the DPI (dots per inch): pixels = inches × DPI. At 300 DPI, 4 inches is 1,200 pixels; at 96 DPI the same 4 inches is 384 pixels.
- Enter the length in inches.
- Set the DPI (300 is the usual choice for print).
- Multiply, or let the converter do it.
To go the other way, divide: inches = pixels ÷ DPI. For centimeters and millimeters, 1 inch is 2.54 cm, or 25.4 mm.

Does DPI Change a Picture on Screen?
No. A picture has a fixed number of pixels. DPI only describes how many of those pixels are spread over one inch when it is printed, so a higher DPI means a smaller print from the same file. On screens the pixel count is what matters; 72 and 96 are common conventions, not a quality setting.
If a picture does not have enough pixels for the print size you want, you can upscale it first or read how to increase the DPI of an image.
