 How to Enlarge a Picture without Losing Quality

Many people would like to enlarge photos. Whether in a wedding ceremony, advertising board, or other occasions that need to display photos in a large frame, it is essential to make pictures bigger. Have you tried to blow up pictures to a larger size but failed with blurry results? Well, expanding picture size is not as easy as you usually think. Because the resolution of a picture is closely connected with its pixels and dots per inch. This article will explain how picture resolution ties with PPI and DPI and how to enlarge a picture without losing quality with the easiest solution that is applicable for all levels.

How PPI and DPI are Connected with Picture Resolution?

  • Pixels per inch (PPI) refers to the measure of resolution on the computer screen, TV screen, or any other display device. It is a term that is often used in web pages, the photography industry, cameras, and digital images. The more pixels in an image, the higher the resolution and the larger the picture size.
  • Dots per inch (DPI) is typically used to refer to the number of dots that can be placed in a line within one inch. It is widely used in the printing industry to describe printed documents. In general, the higher the dots’ intensity, the higher the resolution, and the better quality of the prints. That is why although many images digital devices show are in 72 DPI, they will not make pictures blurry when we see them on computer or phone screens.
