{{Short description| The mass per unit of area of paper}}
{{Redirect|Paper weight|the heavy desktop object|paperweight}}
'''Grammage''' and '''basis weight''', in the [[pulp and paper industry|pulp and paper]] industry, are the [[area density]] of a [[paper]] product, that is, its [[mass]] per unit of [[area]]. Two ways of expressing the area density of a paper product are commonly used:
* Expressed in [[gram]]s (g) per [[square metre]] (g/m<sup>2</sup>), regardless of its thickness ([[#Caliper|caliper]])<ref name="iso536">International Standard ISO 536: Paper and board – Determination of grammage. [[International Organization for Standardization]], Geneva.</ref> (known as ''grammage''). This is the measure used in most parts of the world. It is often notated as ''gsm'' on paper product labels and spec sheets.
* Expressed in terms of the mass per number of sheets of a specific [[paper size]] (known as ''basis weight''). The convention used in the United States and a few other countries using [[Paper size#North American paper sizes|US-standard paper sizes]] is [[pound (mass)|pound]]s (lb) per [[paper ream|ream]] of 500 (or in some cases 1000) sheets of a given (raw, still uncut) basis size.  The traditional British practice is pounds per ream of 480, 500, 504, or 516 sheets of a given basis size. Japanese paper is expressed as the weight in [[kilogram]]s (kg) per 1,000 sheets.

==Grammage==
In the [[metric system]], the mass per unit area of all types of paper and paperboard is expressed in terms of '''grams per square metre''' (g/m<sup>2</sup>). This quantity is commonly called ''[[wikt:grammage|grammage]]'' in both [[English language|English]] and [[French language|French]],<ref>{{Cite web |title=ISO 536:2019 |url=https://www.iso.org/cms/render/live/en/sites/isoorg/contents/data/standard/07/75/77583.html |access-date=2022-10-05 |website=ISO |language=en}}</ref> though printers in most English-speaking countries still refer to the "[[weight]]" of paper.
                            
:<math>\text{Grammage} = \frac{\text{mass} \text{ (g)}}{\text{length} \text{ }(\text{m}) \times \text{width} \text{ } (\text{m})}</math>

Typical office paper has {{convert|80|g/m2|oz/sqft|abbr=on}}, therefore a typical [[A4 paper|A4]] sheet ({{frac|16}} of a square metre) weighs {{convert|5|g|oz|abbr=on}}. The abbreviation "gsm" instead of the standard g/m<sup>2</sup> symbol is also widely encountered in [[English-speaking countries]].

Typically grammage is measured in [[paper mill]] on-line by a [[quality control system for paper, board and tissue machines|quality control system]] and verified by laboratory measurement.

==Basis weight==
Basis weight of paper is the density of paper expressed in terms of the mass (in pound) of a [[paper ream|ream]] of paper of given dimensions and a sheet count.  The American and the traditional British systems are largely the same, with only minor differences: the paper dimensions and the sheet count are different.

=== United States ===
In the US system, the weight is specified in [[avoirdupois system|avoirdupois]] [[pounds (mass)|pounds]] and the sheet count of a [[paper ream]] is usually 500 sheets. However, the mass specified is not the mass of the ream that is sold to the customer. Instead, it is the mass of the uncut "basis ream" in which the sheets have some larger size (parent size). Often, that is a size used during the manufacturing process before the paper is cut to the dimensions in which it is sold. So, to compute the mass per area, one must know
* the mass of the basis ream,
* the number of sheets in that ream, and
* the dimensions of an "uncut" sheet in that ream.

The standard dimensions and sheet count of a ream vary according to the type of paper. These "uncut" basis sizes are not normally labelled on the product, are not formally standardized, and therefore have to be guessed or inferred somehow from trading practice. Historically, this convention is the product of pragmatic considerations such as the size of a sheet mold.

By using the same basis sheet size for the same type of paper, consumers can easily compare papers of differing brands. Twenty-pound bond paper is always lighter and thinner than 32-pound bond, no matter what its cut size, and 20-pound bond ''letter size'' and 20-pound bond ''legal size'' papers are the same weight paper with a different cut size.

However, a sheet of common copy paper that has a basis weight of {{convert|20|lb|kg}} does not have the same mass as the same size sheet of coarse paper (newsprint). In the former case, the standard ream is 500 sheets of {{convert|17|by|22|in|mm|0|adj=on}} paper, and in the latter, 500 sheets of {{convert|24|by|36|in|mm|0|adj=on}} paper. Here are some basic ream sizes for various types of paper. Units are inches except where noted.

Sheets {{convert|17|by|22|in|mm|0}} can be cut into four {{convert|8+1/2|by|11|in|mm|0|adj=on}} sheets, a standard for business stationery known conventionally as ''letter sized paper''. So, the {{convert|17|by|22|in|mm|0|adj=on}} ream became commonly used. The {{convert|25|by|38|in|mm|0|adj=on}} book-paper ream developed because such a size can easily be [[Paper_size#Traditional inch-based paper sizes|cut into sixteen]] {{convert|6|by|9|in|mm|0|adj=on}} [[Book_size#Common formats and sizes|book size]]d sheets without significant waste (nominally {{convert|6+1/4|by|9+1/2|in|mm|0|adj=on}} before trimming and binding).

Early newsprint presses printed sheets {{convert|2|by|3|ft|mm|0}} in size, and so the ream dimensions for newsprint became {{convert|24|by|36|in|mm|0}}, with 500 sheets to a ream. Newsprint was made from ground wood pulp, and ground wood hanging paper ([[wallpaper]]) was made on newsprint machines. Newsprint was used as wrapping paper, and the first paper bags were made from newsprint. The newsprint ream standard also became the standard for packaging papers, even though in packaging papers [[kraft process|kraft]] pulp, rather than ground wood, was used for greater strength.

Paper weight is sometimes stated using the "[[number sign#Usage|#]]" symbol. For example, "20#" means "20 pounds per basis ream of that kind of paper". When the density of a ream of paper is given in pounds, it is often accompanied by its "M weight" (M is 1000 in [[Roman numerals]]). The M weight is the weight (in pounds) of 1000 cut sheets. Paper suppliers will often charge by M weight, since it is always consistent within a specific paper size, and because it allows a simple weight calculation for shipping charges.

For example, a 500-sheet ream of 20# {{convert|8+1/2|by|11|in|mm|0|adj=on}} copy paper may be specified "10&nbsp;M". 1000 cut sheets (or two reams) will weigh {{convert|10|lb|abbr=on}}, half of the four reams of cut paper resulting from the 20# basis ream of {{convert|17|by|22|in|mm|0|adj=on}} paper.

==== Overview of the traditional British system ====
Like the American system, the traditional British system also involves the use of basis weight to express the area density of paper (and, indirectly, paper thickness) in the course of buying and selling paper.  The British paper industry exclusively used basis weight before 1968.<ref>Page 11, [http://www.rttanner.co.uk/highlight/1968/jan%201968%20vol%2064.pdf January, 1968 edition], ''Highlight''</ref>

In the traditional British system, basis weight is also expressed in terms of the weight of an imaginary ream of paper of a certain size.  The underlying concept is that a ream of paper of the stated paper size and of the same thickness as the paper the parties are dealing with would have the stated weight.  The weight is expressed in [[Pound (mass)|pound]].  As to paper sizes (basis sizes), they can, theoretically, be any sizes, but, by custom, a number of common sizes emerged.  In the 1960s, even the metric A1<ref>Page 3, [http://www.rttanner.co.uk/highlight/1967/july%201967%20vol%2062.pdf July, 1967 edition], ''Highlight''</ref> and A2<ref>Page 3, [http://www.rttanner.co.uk/highlight/1967/oct%201967%20vol%2063.pdf October, 1967 edition], ''Highlight''</ref> had been used as basis sizes alongside the British ones.

One ream in the context of basis weight (basis ream) can be 480 sheets, 500 sheets, 504 sheets, or 516 sheets: there is no fixed rule on when a certain definition was applied; however, starting from the 1950s,<ref name="Common British basis weights"/> the trend of moving towards 500 sheets emerged.

Basis weight is commonly expressed in terms of pound per ream of paper of a certain size, in the format of ‘[number]lb [paper size]’ (e. g., ‘21lb large post’ (‘21 pounds per ream of large post paper’)).  Since there are basis reams of different sizes, unless the context leaves no room for ambiguity, the number of sheets in the basis ream is also given after the paper size to avoid misunderstanding: in such case, basis weight is expressed in the format of ‘[number]lb [paper size] [number of sheets of paper in the basis ream]’, such as ‘21lb large post 480’ (‘21 pounds per 480‑sheet ream of large post paper’).  In the United Kingdom, ‘#’ has never been used to express paper weight because it is called ‘hash’, instead of ‘pound’, in British English.

Demy traditionally plays the role of the default basis size for expressing basis weights: in the British paper industry, there was a device, called ‘demy scale’, that was used to measure the weights of different paper samples in pound per ream of demy paper (480‑sheet, 500‑sheet, and 516‑sheet reams).<ref>[[iarchive:paperitsusestrea00daweuoft/page/96/mode/2up|Pages 96 and 97]], ''Paper and Its Uses'' (1919 edition)</ref>

==== Conversion between British basis weights, American basis weights, and grammage ====
It is possible to convert between different basis weights – both British and American – and grammage using different conversion formulae.

To convert between the basis weights of different paper with the same basis‑ream size (e. g., from {{abbr|lb large post 500|pound per 500‑sheet ream of large post paper}} to {{abbr|lb demy 500|pound per 500‑sheet ream of demy paper}}), the following formula can be employed:<ref>[https://babel.hathitrust.org/cgi/pt?id=uc1.d0001467554&seq=536 Page 368], November–December, 1894 edition, ''The British Printer''</ref>

Area of one sheet of paper in the target ream × Weight of the source ream ÷ Area of one sheet of paper in the source ream

To convert between the basis weights of different paper with different basis‑ream sizes (e. g., from {{abbr|lb large post 480|pound per 480‑sheet ream of large post paper}} to {{abbr|lb demy 500|pound per 500‑sheet ream of demy paper}}), the relevant formula is below:

(Number of sheets of paper in the target ream × Area of one sheet of paper in the target ream) × Weight of the source ream ÷ (Number of sheets of paper in the source ream × Area of one sheet of paper in the source ream){{efn|This formula and the previous formula are essentially the same, with the only difference being the inclusion of the numbers of sheets of paper in both the source ream and the target ream.  Technically, the numbers of sheets of paper should also be included in the previous formula.  However, since the numbers of sheets of paper in the two reams will be cancelled out if they are the same, they can be omitted in the previous formula.}}

To convert between the basis weights of the same paper with different basis‑ream sizes (e. g., from {{abbr|lb large post 480|pound per 480‑sheet ream of large post paper}} to {{abbr|lb large post 500|pound per 500‑sheet ream of large post paper}}), one may either use the previous formula or the one below:

Weight of the source ream × Applicable conversion factor from the table below<ref>[[iarchive:paperitsusestrea00daweuoft/page/148/mode/2up|Page 148]], ''Paper and Its Uses'' (1919 edition)</ref>

To convert from a basis weight to its equivalent grammage, the following is the applicable formula:<ref name="lb&gsm">[[iarchive:dli.ernet.18571/page/156/mode/2up|Page 157]], ''Paper and Its Uses'' (1939 edition)</ref>

Weight of the basis ream × 703,125 ÷ Area of one sheet of paper in the basis ream in square inch × Number of sheets of paper in the basis ream

To convert from grammage to the equivalent basis weight, the formula below can be used:<ref name="lb&gsm"/>

Area of one sheet of paper in the basis ream in square inch × Number of sheets of paper in the basis ream × Value of gram per square metre ÷ 703,125

Utilising the aforementioned formulae, it is possible to work out the conversion factors for converting between various British and American units of basis weight and the gram per square metre:

By the same token, 1 ‘double’ unit is always equal to {{sfrac|1|2}} ‘single’ unit and 2 ‘quad’ unit, respectively; and 1 ‘quad’ unit is always equal to {{sfrac|1|2}} ‘double’ unit and {{sfrac|1|4}} ‘single’ unit, respectively.  Due to the rounding of the conversion factors in this table, calculating with the conversion factors alone may not produce such results automatically.

Using British basis sizes and the 500‑sheet basis‑ream (a traditional British basis‑ream size that coincides with the modern standard definition of ‘ream’), and with the help of the aforementioned conversion formulae or conversion factors, it is possible to express the paper weights of different types of paper in everyday life using British units of basis weight: the typical photocopier paper that is used as all‑purpose paper is 17{{sfrac|1|4}} or 19{{sfrac|3|4}}{{abbr|lb large post|pound per ream of large post paper}} (70 or 80gsm);<ref>[https://colourgraphics.com/blog/what-is-gsm-paper/#mcetoc_1hdlpjhi122 GSM Paper: the Complete Guide]</ref> personal and business letter paper, especially that with engraved letterheads, is typically 24{{sfrac|3|4}}–29{{sfrac|1|2}}{{abbr|lb large post|pound per ream of large post paper}} (100–120gsm);<ref>‘[https://www.solopress.com/blog/tutorials/what-is-gsm-paper-weight/ What is GSM Paper Weight?]’, Solopress Blog</ref> greetings cards are usually 85{{sfrac|1|4}}–106{{sfrac|3|4}}{{abbr|lb double crown|pound per ream of double crown paper}} (200–250gsm);<ref>‘[https://mankeymonkey.co.uk/blog/understanding-the-different-gsm-weights-for-card-and-paper-supplies Understanding the Different gsm Weights for Card and Paper Supplies]’, Mankey Monkey</ref> newspaper paper is typically 15–23{{sfrac|1|2}}{{abbr|lb double crown|pound per ream of double crown paper}} (35–55gsm);<ref name="List of grammage">‘[https://www.thepaperbox.co.uk/blog/what-paper-or-card-thickness-gsm-should-you-choose/ Paper GSM Guide]’, The Paperbox Limited</ref> business cards are usually 128–149{{sfrac|1|4}}{{abbr|lb double crown|pound per ream of double crown paper}} (300–350gsm);<ref name="List of grammage"/> two‑ply toilet rolls and paper kitchen towels are 7{{sfrac|3|4}}{{abbr|lb double crown|pound per ream of double crown paper}} (31gsm)<ref>For example, Kleenex toilet paper sold at https://www.galleonsupplies.co.uk/cheap-toilet-rolls-c10/bulk-pack-toilet-tissue-2-ply-p118.</ref> (both layers combined) and 17{{abbr|lb double crown|pound per ream of double crown paper}} (40gsm),<ref>For example, the paper kitchen towel sold at https://www.amazon.co.uk/Pack-20-Centrefeed-Absorbent-Commercial/dp/B0CC6BS768.</ref> respectively; and the typical department‑store wrapping paper is commonly 46{{sfrac|1|2}}–65{{abbr|lb double imperial|pound per ream of double imperial paper}} (50–70gsm).<ref>For example, the wrapping paper sold at https://www.transpack.co.uk/gift-display/coloured-kraft-wrapping-paper and https://www.makkipak.co.uk/product/kraft-paper-rolls-70gsm/.</ref>  In the traditional British system, large post, double crown, and double imperial are common British basis sizes for writing paper, printing paper and other paper that is not writing or wrapping paper, and wrapping paper, respectively.  ‘500’ is omitted because it is clear from the context that a ‘ream’ is 500 sheets.

==Caliper==
Paper thickness, or caliper, is a common measurement specified and required for certain printing applications. Since a paper's [[density]] is typically not directly known or specified, the thickness of any sheet of paper cannot be calculated by any method. Instead, it is measured and specified separately as its [[caliper]]. However, paper thickness for most typical business papers might be similar across comparable brands. If thickness is not specified for a paper in question, it must be either measured or guessed based on a comparable paper's specification.

Caliper is usually measured in [[micrometres]] (μm), or in the United States also in [[thousandth of an inch|mil]]s (1&nbsp;mil = {{frac|1000}}&nbsp;in = 25.4&nbsp;μm). Commonly, 20-pound [[bond paper]] ranges between roughly {{cvt|97|and|114|μm|in}} in thickness.<ref>{{cite web|url=http://www.havilandprinting.com/papercomparisons/|archive-url=https://web.archive.org/web/20121022063704/http://www.havilandprinting.com/papercomparisons/|url-status=dead|archive-date=22 October 2012|title=Paper Comparisons|date=22 October 2012}}</ref>

The [[paper density]] is calculated by [[division (mathematics)|dividing]] the grammage over the caliper, and is usually expressed in [[gram per cubic centimetre|grams per cubic centimetre]] (g/cm<sup>3</sup>)<ref>{{cite web |url=https://www.iso.org/obp/ui/#iso:std:53060:en |title=ISO 534:2011(en) Paper and board — Determination of thickness, density and specific volume}}</ref> to [[cancel out]] the mathematical need for [[unit conversion]]s between [[metre]]s and micrometres (a [[conversion factor]] of 1,000,000).{{fact|date=March 2023}}
