Understanding Key Elements for a Successful Passport Photos

A pixel is a single colored point on a screen or in a digital image or video. When many pixels are combined, they form an image. Pixels are the building blocks of everything that is visible on a screen, and one megapixel equals one million pixels.

The term "pixel" was coined in 1965, derived from the first syllables of the two English words "picture" and "element."

The number of pixels in a photo determines its resolution. The higher the number of pixels per unit area, the sharper and more detailed the image. The number of pixels per inch is expressed as dpi.

Pixels on a Passport Photo

In passport photos, a minimum resolution of 600 dpi is required to ensure the image is sharp. The photo paper used must be of high quality and smooth to meet the passport photo requirements.

To meet the 600 dpi resolution requirement for passport photos, we use an official photo printer that meets high-quality standards. Our printer is capable of printing passport photos at 600 dpi on grams-gram photo paper.
