It is a common practice to select paper sizes for printing by subtracting one-half or two-thirds of the dimensions of the previous or following sheet. The quantity of trash, possible time savings, and maximum print size should all be taken into account when determining the appropriate printer page size.
To keep the printer page size formats consistent, the sizes are reduced or increased by a factor of half or two.
“A” series of printer page sizes
A0 is the greatest size, and one square metre is equal to one square metre. An A0 sheet can be made into an A1 by folding it in half. This will become A2 when folded in half a second time. This goes all the way down to the tiniest sizes that are now accessible. A4 sheet paper is the basic default size of printing paper used nowadays.
A0, A1, A2, A3, A4, A5, A6, A7, A8, A9, A10
B-Sized Paper — Suitable for book and poster printing.
The largest workable sheet in commercial printing press measures is defined by these sizes. In addition to books and posters, this format gives consumers a greater range of options when it comes to their printing requirements in terms of size formats.
Paper with a C-size dimension is used for envelopes.
To accommodate the most common A-sized paper goods, envelopes come in C sizes. A C4 envelope will fit an A4 sheet of paper perfectly, without any issues. For example, an A5 page will fit into a C5 envelope, and vice versa. The ISO 269 International Standard for paper sizes defines the dimensions of the C series, which is often used for envelopes. The C series envelope falls in the middle of the A and B envelope sizes, hence it is frequently used in conjunction with the A and B series sheets.
Sizes RA & SRA as supplied by the manufacturer
Raw Format ‘A,’ or RA paper, is a specific size.
A-sized papers are slightly larger than their A-sized counterparts in terms of untrimmed paper sizes.
Supplementary Raw Format ‘A’ (SRA) paper size
Commercial printing utilises a bigger untrimmed size known as SRA (Super Ripple Aperture). Additional ink bleeds are allowed before being clipped for the final A sized sheet of finished paper.
Typical A-sized paper dimensions
The dimensions of a sheet of paper (mm)
841mm by 1189mm in A0
594mm by 841mm in A1
420 x 594 mm, or 420 x 594 inches in A2
An A3 sheet of paper with dimensions of 297 x 420 mm
It’s an A4 paper that measures 210x297mm.
Paper size is 148 x 210mm, A5
For A6, 105mm x 148mm
This is the same size as an A7 (74 x 105 mm).
A8: 52 mm x 74 mm sized paper
Size for B-printing paper
279 x 432 mm, or 11 x 17 inches, is the size of the second piece of paper.
Size for C paper is about the same size as A4 paper. For architectural design purposes, “C” sized paper is 18″ by 24″. Printers like the HP DesignJet family of inkjet plotters may print on opaque bond, translucent bond, or vellum, as shown in the table below.
Those are the various printer page sizes formats available on the market.
