European standard sheet sizes are defined by the ISO 216 standard, which includes the A, B, and C series of sizes. The most common is the A series, where A0 is the largest and subsequent sizes, like A4 (210mm x 297mm), are derived by halving the previous size parallel to its shorter sides. This system ensures a consistent aspect ratio of 1:√2, making it easy to scale documents without altering design elements. A4 is widely used for letters and documents across Europe and beyond.
