At Kite, they are labelled simply as cardboard sheets to express their ability to be used for many varying applications. The double wall cardboard layers are available in half Europa size up to a full pallet but can, of course, be cut down to custom sizes as required. Rolls of corrugated paper The weight of an A-series sheet of a given paper weight can be calculated by knowing the ratio of its size to the A0 sheet. For example, an A4 sheet is 1⁄ 16 the size of an A0 sheet, so if it is made from 80-g/m 2 paper, it weighs 1⁄ 16 of 80g, which is 5g.

The following international paper sizes are included in Cascading Style Sheets (CSS): A3, A4, A5, B4, B5. [2] Our single wall corrugated cardboard sheets can also be utilised as edge protectors, so they are remarkably versatile. Double wall cardboard sheets A series sizes are related in that the smaller dimension of a given size is the larger dimension of the next smaller size, and folding an A series sheet in half in its larger dimension—that is, folding it in half parallel to its short edge—results in two halves that are each the size of the next smaller A series size. As such, a folded brochure of a given A-series size can be made by folding sheets of the next larger size in half, e.g. A4 sheets can be folded to make an A5 brochure. The fact that halving a sheet with an aspect ratio of 2 {\displaystyle {\sqrt {2}}} results in two sheets that themselves both have an aspect ratio of 2 {\displaystyle {\sqrt {2}}} is proven as follows: The paper sizes bigger than A0, 4A0 & 2A0, aren't formally defined by ISO 216 but are commonly used for oversized paper. m {\displaystyle {\sqrt[{4}]{2}}\,\mathrm {m} } by 1 2 4 m {\displaystyle {\frac {1}{\sqrt[{4}]{2}}}\,\mathrm {m} } .RA & SRA sizes define untrimmed paper for commercial printing. These formats are designed to allow for There are 11 sizes in the A series, designated A0–A10, all of which have an aspect ratio of a b = 2 ≈ 1.41421 … {\displaystyle {\frac {a}{b}}={\sqrt {2}}\approx 1.41421\ldots } , where a is the long side and b is the short side. The B series paper sizes are less common than the A series. They have the same aspect ratio as the A series: If you have any special applications that require non-standard double wall cardboard sheets, they can easily be cut to the required size and shape (please note we do not offer a cutting service). Since A series sizes share the same aspect ratio ( 2 ) , {\displaystyle ({\sqrt {2}}),} they can be scaled to other A series sizes without being distorted, and two sheets can be reduced to fit on exactly one sheet without any cutoff or margins.

x 19"). This gives it an aspect ratio of 1:1.468 rather than the 1:root 2 aspect ratio of the ISO series paper sizes. The international paper size standard is ISO 216. It is based on the German DIN 476 standard for paper sizes. Each ISO paper size is one half of the area of the next larger size in the same series. ISO paper sizes are all based on a single aspect ratio of the square root of 2, or approximately 1:1.41421. There are different series, as well as several extensions. If your consignments require the ultimate in protection, you should be using our double wall cardboard sheets.In actuality the A3+/Super A3 name is quite misleading as this paper size is known as B+ or Super B in the United States
