Paper formats

Paper formats refer to standardized sizes of sheets used for writing, printing, and publishing. Different formats are designed for specific purposes, such as letters, documents, or printing materials. Common formats include A4, widely used internationally, which measures 210 x 297 mm, and Letter size, popular in the U.S., measuring 8.5 x 11 inches. These sizes ensure consistency across documents and ease of handling, printing, and filing. Variations exist globally, but they all aim to provide a convenient, predictable size for various tasks.
