Both are available in the US, while in Canada, mainly the Staples ARC system is available. These two systems sell products based on letter and junior (5.5 x 8.5 inch, which is half of letter size) sizes. They sell "narrow-ruled" (whose line height is approx. 6 mm or 1/4 inch) loose leaf paper, which is rare for 3-hole letter size papers.
Although metric, based on the A4 paper size, and named to suggest that it is part of the official ISO 216 paper sizes, it is only a de facto standard. It is often referred to as (metric) "foolscap" or "folio" because of its similarity to the traditional foolscap folio size of 8 + 1 ⁄ 2 in × 13 + 1 ⁄ 2 in (216 mm × 343 mm).
It has the height of Canadian P4 paper (215 mm × 280 mm, about 8 + 1 ⁄ 2 in × 11 in) and the width of international A4 paper (210 mm × 297 mm or 8.27 in × 11.69 in), i.e. it uses the smaller value among the two for each side. The table shows how this format can be generalized into an entire format series.

The density of paper ranges from 250 kg/m 3 (16 lb/cu ft) for tissue paper to 1 500 kg/m 3 (94 lb/cu ft) for some specialty paper. Printing paper is about 800 kg/m 3 (50 lb/cu ft). [22] Paper may be classified into seven categories: [23] Printing papers of wide variety. Wrapping papers for the protection of goods and merchandise. This includes ...
The precise origins of the dimensions of US letter-size paper (8.5 × 11 in) are not known. The American Forest & Paper Association says that the standard US dimensions have their origin in the days of manual papermaking, the 11-inch length of the standard paper being about a quarter of "the average maximum stretch of an experienced vatman's arms".

A paper tape, constructed from punched cards, in use in a Jacquard loom. The large holes on each edge are sprocket holes, used to pull the paper tape through the loom. Perforated paper tapes were first used by Basile Bouchon in 1725 to control looms. However, the paper tapes were expensive to create, fragile, and difficult to repair.
For the US letter paper size (8 + 1 ⁄ 2 by 11 inches, 220 by 280 mm), a three-hole standard is widely used. The holes are positioned symmetrically, with the centers 4 + 1 ⁄ 4 inches (108 mm) apart. It requires paper formats that are at least 9 + 1 ⁄ 2 inches (241 mm) high.
