Tips: What is the Best Size for Enlarging A Picture

Before you enlarge a picture for printing, you need to know the best pixel resolution for the desired print size. Usually, the quality of printing pictures is decided by DPI, which means the pixel dots contained in an inch of the picture. And the DPI for the quality standard is divided into three categories:

◆ Decent: 100-150 DPI (dots per inch)

◆ Above Average: 150-300 DPI

◆ Professional Grade: Above 300 DPI

In this way, different sizes of pictures also require different pixel resolutions to keep the high DPI. For example, if you want to print a 24×36 size picture, the optimal 300DPI needs 10800 × 7200 resolution. And if you only need a 4×6 printed picture, the 1800 × 1200 resolution is enough. Please check the recommended settings for each printing size in the following list. And you can follow it to enlarge a picture without losing quality.
