What is the standard blueprint paper size?
Blueprints and house plans will come in several standard sizes. Two of the most common architectural drawing sizes are 18” x 24” and 24” x 36”, but the Business Box also prints construction plans of 36” x “48” sizes. Large sizes are necessary on bigger and more detailed projects. Regardless of the blueprint paper size being used, its purpose is to show a trained person how to build that particular projects.
North American architects typically use the ARCH sizes for their large format drawings. There are two main paper size standards in use around the world: the international (ISO) A series and the North American ANSI sizes. For reference purposes, all common sheet sizes for technical drawings are listed below.
