A 4x4 picture equals 4 x 4 inches or 10.16 x 10.16 cm, and its pixel size depends on resolution. For example, at 300 DPI, it becomes 1200 x 1200 pixels for high-quality printing. Lower resolutions like 72 DPI result in smaller pixel sizes such as 288 x 288 pixels. This flexibility makes it suitable for both print and digital use. https://clippingexpertasia.com/blog/how-big-are-4x4-pictures/
