Printer Paper Dimensions In The United States

Creating Custom Paper Sizes for Printing in Windows | HP Printers | @HPSupport

If you’re in the United States or Canada, the most common paper size you’ll encounter is letter-sized paper, which is 8.5 inches by 11 inches. Generally, if someone asks you to print a document for business, government or academic purposes, the paper size of 8.5 inches by 11 inches is the size they’ll expect to see, unless they say otherwise. It’s the most common paper size available for your printer at most office supply stores or stationery stores.

Documents are almost universally printed in portrait format, meaning that the longer dimension of the paper is treated as the vertical dimension. The alternative format, known as landscape format, generally is used only for printing specialized-use documents, such as charts, photos or other graphics.

Other common sizes you may encounter include legal size, which is 8.5 inches by 14 inches. This format is the same width as letter paper, but the paper is three inches longer on the long side. As the name suggests, it’s sometimes used as the standard paper size for certain types of legal documents.

Another paper size called ledger or tabloid, is 11 inches by 17 inches. When the paper is used in portrait orientation, it’s called tablet paper when it’s used in landscape orientation, it’s called ledger. As the names imply, it’s sometimes used for newsletters and for financial documents, as well as for other charts that won’t fit nicely on letter-sized paper or on legal-sized paper.

Overview Of Iso Paper Sizes

=\,} r=}}}

The variables are the distinct first terms in the three geometric progressions of the same common-ratio equal to the square root of two. Each of the three geometric progressions is formed by all possible paper dimensions of the series arranged in decreasing order. This interesting arrangement of dimensions is also very useful – not only it forms a geometric progression with easy to remember formulae, it also has that each consecutive pair of values will automatically correspond to the dimensions of a standard paper format in the series.

The tolerances specified in the standard are

  • ±1.5 mm for dimensions up to 150 mm ,
  • ±2 mm for lengths in the range 150 to 600 mm and
  • ±3 mm for any dimension above 600 mm .

How Is Copy Paper Made

Copy paper is made from a fibrous substance known as cellulose that comes from trees. The cellulose is diluted in water.

  • Fun fact: It takes nearly 100 pounds of water to make one pound of paper.

Chalk is then used to fill in spaces between the fibers and give a brighter, whiter hue to each sheet. Fibers are then ground into even finer microfibers.

Once the right consistency is achieved, the pulpy paper substance is then spread on a screen. Depending on the desired level of copy paper brightness, tints of blue and/or purple dye are used to transform the naturally yellow-tinted pulp to a whiter shade.

To extract the water and leave behind paper, pulp is put through a machine that squeezes out the water. Then, its put into an oven to further extract water. From there, the paper is saturated with starch to strengthen it and smooth away any stray fibers. Finally, the copy paper is dried and pressed to ensure consistency of weight or thickness.

Printer Paper Sizes Explained In Plain Language

Have you ever looked at the cover of a box of printer paper and wondered what all the numbers mean? Have you wondered what is the difference between A5, A4 or Tabloid, and why there are so many confusing numbers on the box? Dont worry, were here to demystify and simplify the confusing world of paper sizes.

Though other paper size standards exist, there are two main systems in use today, the international and North American systems. The international standard, also known as the ISO 216 standard, is used throughout the world. Today, we will focus on the North American system, used primarily in the USA and Canada. The standard includes the familiar Letter and Legal , but also some additional sizes you may not use as often.

Printer Paper Sizes Explained


Have you ever wondered why a standard sheet of paper is 8.5″ x 11″? Those numbers may look like they were chosen at random, but actually, there’s a good reason for these precise measurements. The two-sheet mold for papermaking was invented by the Dutch in the mid-1600s. The average maximum reach of a workman’s arms was 44, and the paper molds were 17″ deep. Therefore, 44″ x 17″ sheets were produced, which were then divided into eight pieces atyou guessed it8.5″ x 11″.

American legal paper was standardized to 8.5 x 14 during the Great Depression. Herbert Hoover didnt want to put traditional paper-makers out of business during a time of such economic hardship, so the traditional 8.5 width remained in place, even though paper was more commonly being made by machine. The additional length for legal documents also makes perfect sense: it allows room for a signature.

B Series Paper Sizes Definition

The B series paper sizes are defined in ISO 216in the following way.

The B series paper sizes were created in order to provide paper sizes that weren’t coveredby the A series, but also use an aspect ratio of 1:root2. B sizes are defined as size B being thegeometric mean of size A and size A. The Geometric Means of 2 numbers being the square rootof the product of the two numbers.

This system gives a useful property for enlarging and reducing documents in that the enlargementfrom A to B is the same as that from B to A.

As with the A series paper sizes, the standard lengths and widths are rounded to the nearest millimetre.

Printer Paper Dimensions Abroad

Outside of the United States and Canada, another system of paper sizes is commonly used. This size system is based on metric measurements, and a size known as A0, is designed to be 1 square meter in area. It is 1189 millimeters by 841 millimeters.

Other sizes include A1, A2, A3, A4 and so on. Each size can be generated from the previous size by halving the length of the longest size and preserving the length of the shorter size. For example, A1 is 841 millimeters by 594 millimeters, since its longest side is the same as the shortest side of A0 paper and the shorter side is half the length of A0 paper’s longest side.

This means that two A1 sheets can be printed on one A0 sheet four A2 sheets can be printed on one A0 sheet, and so on. The most commonly used format in this series is A4, which is essentially the equivalent of U.S. letter-sized paper. The A4 sheet It is 297 millimeters by 210 millimeters, which is 8.3 inches by 11.7 inches, which is slightly taller and slightly less wide than the letter-sized paper format of 8 and 1/2 inches by 11 inches.

Carbonless copy paper is similar to carbon paper in that it has the same white-pink-yellow triple sheet construction that transfers the original copy to the bottom two sheets. The only difference is, instead of carbon-based ink, these sheets have a specially formulated, micro-encapsulated dye on the back of the white sheet and a coating of clay at the front of the bottom sheet. Pressure from a pen or typewriter key transfers this ink to all three copies at the same timeminus the carbon.

Are There Other Standard Paper Series

While A-size paper is the most commonly used around the world, there are other paper sizes as well. ISO 219 also includes a B-Series and C-Series. The B-Series has slightly wider dimensions, which makes them a great size for posters. The C-Series are also a bit wider than the A-Papers, which is why they are often used for envelopes: A-Series papers can easily slide inside of envelopes with C-Series dimensions.

Sizes In United States And Canada

In the United States and Canada the normal size of paper is called letter size, or sometimes US letter. It is 8 12inches wide and 11 inches long .

The other common size of paper in the US is called legal, or sometimes US legal. It is also 8 12 inches wide, but it is 14 inches long. It is similar to the size called foolscap in Britain.

Another size is called executive. It is 7 14 inches wide by 10 12 inches long. It is not very common. It is sometimes used for writing personal letters to people.

There is also a size called tabloid. It is 11 inches wide, and 17 inches long. That is the same size as two pieces of letter size put next to each other.

There are also many other paper sizes used for writing notes, for big posters, for books, and for other things.

What Are Sra Paper Sizes

ISO 219 includes a series of RA and SRA paper sizes. SRA stands for Supplementary Raw Format A, and these standard sizes are meant to be used for documents that are to be trimmed.

SRA paper sizes include an additional bleed area and have dimensions that are exactly 105% the size of the corresponding A-Series paper sizes. That means SRA4 has dimensions 5% greater than A4, SRA3 has dimensions 5% greater than A3, SRA2 has dimensions 5% greater than A2, and SRA1 has dimensions 5% greater than A1, etc. etc.

Paper Weight And Thickness

Printer Paper

Taken together, the paper weight and thickness reveal how sturdy a stock is, with thicker, heavier paper providing greater durability than a thin, light one.

Paper thickness is usually considered when looking at cardstock and, in most cases, measures the thickness of paper in points, where one point equals one-thousandth or .001 inches. So, 10 pt. paper is .01 inches thick, 20 point is .02 inches, and so on.

In the United States, the weight of paper stocks is usually done in pounds, which is the actual weight of 500 sheets of the basis size of the paper in question. Since the basis size may vary, comparing paper weights can be hard to do. For example, a 28-pound multipurpose paper is probably not the same weight or thickness as a 28-pound premium or cardstock paper.

Lower numbers, including 20 pounds and 24 pounds, are the most common weights for standard copy and multipurpose paper, while higher numbers indicate a heavier, thicker sheet.

In most cases, the thicker the sheet, the heavier it is, although there are cases where a dense paper can be heavy without being thick.

The weight and thickness of the paper used in a printing job can make a big difference in its quality and cost. For example, mailed pieces are usually charged by weight, so lighter, thinner stocks may work well. Professional presentations, resumes, and correspondence often call for heavier, thicker stocks, as do jobs that aim for archival quality.

Office Paper Sizes As Letter Legal Tabloid And More

The ISO standard paper sizes are not commonly used in the United States and Canada. Instead paper formats like “Letter” , “Legal” , “Executive” , and “Ledger/Tabloid” are widely used. The “Letter”, “Legal”, “Tabloid”, and other formats are defined in the American National Standard ANSI X3.151.

US, Imperial paper
Index Card 5 x 8 127 x 203
Letter, US A, ANSI A 215.9 x 279.4
5 1/2 x 8 1/2
Super royal
Tabloid, US B, ANSI B 279.4 x 431.8
U.S. government writing 203 x 267 8 x 10 1/2

There is also the American National Standard ANSI/ASME Y14.1 Decimal inch drawing sheet size and format for technical drawing paper sizes and some other unsystematic formats for various applications in use.

  • Miscellaneous – Engineering related topics like Beaufort Wind Scale, CE-marking, drawing standards and more
  • Drawing Tools – 2D and 3D drawing tools

The Systems In Existence

Though other paper size standards exist, there are two predominant systems in use today. They are the international and North American systems.

As the term implies, the international standard, also known as the ISO 216 standard, is used throughout the world. It is based on an aspect ratio of the square root of two, like the side of a square and its diagonal. This idea was originally proposed by the German scientist Georg Christoph Lichtenberg in 1786. In 1922, Dr. Walter Porstmann brought Lichtenbergs ideas into being in Germany. This new standard was known as the DIN 476 standard. The system became widely used during World War II. The most commonly used ISO paper size is A4.

The North American system is used primarily in the USA and Canada. The current sizes are based on traditional sizes such as Letter and Legal . The names of North American sizes have started with ANSI ever since the adoption of ANSI/ASME Y14.1 by the American National Standards Institute in 1995. Though the sizes now begin with ANSI, they are nevertheless based on the traditional sizes.

    Choosing The Right Paper

    Now that you know all the different types of paper and the specifications that separate them, it’s time to choose the right material for you. First, think of the kind of document you wish to print and how you will need the final work to look. Then, determine the types of paper supported by your printer and find the best option that fits within both parameters. Remember that if you find a paper with a coating or specific feature you like, there may be other variations of that paper that work better with your particular printing device.

    A3 Printing Vs A4 Printing

    A4 doesnt just indicate a specific paper size. It can also refer to a type of printer.

    Like A4 is considered the standard paper size, A4 printers are standard printers. That doesnt mean A4 printers cant have extra features like scanners and email connectivity. It just means that theyre only equipped to handle print jobs that require A4/Letter-sized paper or smaller.

    If you need to print anything larger than that, youll need a different kind of printer. The other standard option for most companies, organizations, and home offices is the A3 printer. As the name suggests, A3 printers can print anything up to the A3 page size .

    What Are The Differences Between Iso Standards And North American Standards

    There are several key differences between the paper sizes laid out in ISO 216 and those used in North America.

    Most importantly, North American standards are designed for the imperial measurement system rather than the metric system. Letter size paper in the USA measures an easy-to-remember 8.5 by 11 inches. To compare, the closest ISO equivalent, A4 paper, measures 210 × 297 mm. That equals 8.27 x 11.7 when expressed in inches, which is a decidedly less user-friendly number.

    Another important difference between North American and international paper sizes is the aspect ratio. ISO A-Series paper always has an aspect ratio of 1 to 2. This means that the height and width relate to each other in the same way that the side and diagonal of a square do.

    Standard paper sizes in the United States, however, do not have a consistent aspect ratio.

    The differences are hardly noticeable to the naked eye. Most people wouldnt perceive the difference in dimensions between standard US letter size paper and ISO A4 paper unless they were placed side by side.

    The Letter Size paper is the common format of paper which was made specifically for use with typewriters in the past for easy insertion into letters. This is measured at 8-1/2x11inches. The size stuck with common printing needs so that those who still write letters, print papers and much more can easily create their documents.
