Choices in Architect Drawing Paper

Architects drawing paper, also known as drafting paper, is specially formulated to be used with pencils or pen and ink yet still be erasable. The two primary materials from which architects drawing paper are vellum and polyester. Each comes in many different forms, and each has its unique qualities.
Vellum Paper

Vellum paper, which is translucent, is made from plasticized 100% new rag cotton fiber. Changes in temperature or humidity do not affect its usefulness. To meet different needs, vellum paper comes in pads, sheets, and rolls. One brand, Clearprint, is known for being made translucent without the use of solvents. It is of archival quality yet allows for erasing and redrawing with pen or pencil. It is strong and resists yellowing, cracking or ghosting. It is available in a variety of styles.

Pads of 16lb translucent paper are available from 8.5" X 11" to 18" X 24" in size. If a larger size is needed, the same paper comes in sheets up to 36" X 48" and even in rolls up to 72" X 50 yards. Gridded paper sheets from 8.5" X 11" to 30" X 42" are also available.

Polyester Drawing Film

Polyester, or Mylar, drafting film is also archival and is superior to vellum paper. It is strong, so it resists tearing or cutting. It will not stain or become brittle or discolored. Chemical matting allows for a suitable surface upon which to draw with either pencil or pen and ink, yet it can withstand multiple revisions and changes. As with the vellum paper, Mylar is available in different types and sizes.

In three or four mil thicknesses, the film comes in either one side/single matte or two side/ double matte. The five and seven mil thicknesses are available in single matte only. The film comes in rolls from 36" X 50 yards to 54" X 50 yards. Sheets come in sizes from 8.5" X 11" to 36" X 48".

Vellum Paper or Mylar film. Sheets or rolls. The choice is yours.
