What is a common resolution for high-quality printed photographs?

A common resolution for high-quality printed photographs is 300 ppi (pixels per inch). This resolution is widely accepted in the printing industry because it ensures that images have sufficient detail and clarity when printed. At this resolution, photographs can maintain high fidelity, allowing for sharp images with smooth gradients and fine detail, which is critical for professional quality in print work.

While lower resolutions, such as 72 ppi, are often adequate for digital displays and can lead to faster loading times on websites, they do not provide enough detail for print quality. Similarly, although 150 ppi might be acceptable for some less demanding printing tasks, it generally does not meet the standards required for high-quality photographic prints. Higher resolutions such as 600 ppi can provide even more detail but are often unnecessary for most standard printing purposes, as the differences may not be perceivable to the naked eye in normal viewing conditions and can lead to excessively large file sizes. Thus, 300 ppi is the standard for producing high-quality prints that professionals in graphic design and photography strive to achieve.
