The size of printer paper in pixels depends on the paper size. The most common paper size in the US is 8.5 x 11 inches, which translates to 2550 pixels wide and 3300 pixels tall at a resolution of 300 pixels per inch (PPI) for good quality printing. For excellent print quality, the resolution of the artwork should be set at 3400 pixels wide and 4400 pixels tall. However, it is important to note that the size of printer paper in pixels may vary depending on the country and paper size. For example, the A4 paper size, which is commonly used in Europe, is 210 x 297 mm, and at a resolution of 300 PPI, it translates to 2480 x 3508 pixels. To determine the size of printer paper in pixels, it is necessary to know the paper size and the desired resolution.
