A standard 4×6 photo measures 4 inches in width and 6 inches in height, creating a rectangular shape that works well for both landscape and portrait images. In metric units, the size converts to approximately 10.16 × 15.24 cm or 101.6 × 152.4 mm. Because of its practical size, it fits easily into albums, frames, and envelopes. https://clippingexpertasia.com/blog/how-big-is-a-4x6-photo/
