The modern standard for a bundle of writing paper is 1,000 sheets. These 1,000 sheets can be made up of either 40 quires or two reams. As with quires and reams, these measurements do occasionally vary depending on the type of paper. (For example, poster-size paper may sell in bundles of 1,032 sheets.)

A ream of paper is a quantity of sheets of the same size and quality. International standards organizations define the ream as 500 identical sheets. [1] [2] [Note 2] This ream of 500 sheets (20 quires of 25 sheets) is also known as a 'long' ream, and is gradually replacing the old value of 480 sheets, now known as a 'short' ream. Reams of 472 and 516 sheets are still current, [13] but in retail outlets paper is typically sold in reams of 500. As an old UK and US unit, a perfect ream was equal to 516 sheets. [9]

Copy and print paper in a ream of 500 sheets comes in a case of 10 reams. How many dozens are in a ream? Internationally, a standard ream is defined as 500 sheets of paper that are of the same size and quality. Chamberlayne, John, John (1710).

While the majority of paper is made from pine trees, often other trees are used to create the pulp that will then become a sheet of paper. As well as the different types of trees used, another consideration is the fact that trees will always vary in the size and shape. Some trees will be tall with thin trunks while others may be shorter and wider. Of course, trees will always vary depending on their age, environment and type of tree. How much paper comes from one tree, on average? Paper has been around for thousands of years, but it wasn’t until the 19th century that paper manufacturing became more efficient and affordable. The term “ream” has its roots in the early days of paper production when paper was made by hand. A ream of paper originally referred to a bundle of 480 sheets of paper, which was the amount of paper that could be made by one person in a day. Wolff, Christoph (2000). Johann Sebastian Bach: The Learned Musician. New York: W. W. Norton & Company. p.167. In fact, on average, an office will use the equivalent of one tree every year, even in offices that limit their paper usage and strive for a paperless office. Another consideration is that coated paper that is used for high-quality printing and magazines will require more pulp. In fact, one tone of coated magazine paper uses over 15 trees. For paper used for newspapers, it takes around 12 trees to create one tonne of newspaper. When you consider how many magazines and newspapers are printed and distributed across the world, it is difficult to visualise the number of trees being used. Considerations for calculationsA paper bundle is a quantity of sheets of paper, currently standardized as 1,000 sheets. A bundle consists of two reams or 40 quires. As an old UK and US measure, it was previously equal to 960 sheets. [9] a b c d e Cardarelli, F. (2003). Encyclopaedia of Scientific Units, Weights and Measures. Their SI Equivalences and Origins.

sheets: (20 short quires of 24 sheets) – now called 'short' ream (as an old UK and US measure, in some sources, a ream was previously equal to 480 sheets) [9] The word 'ream' derives from Old French reyme, from Spanish resma, from Arabic rizmah 'bundle' (of paper), from rasama, 'collect into a bundle'. (The Moors brought manufacture of cotton paper to Spain.) The early variant rym (late 15c.) suggests a Dutch influence. [14] (cf. Dutch riem), probably during the time of Spanish Habsburg control of the Netherlands.

Typical office paper has 80 g/m2 (0.26 oz/sq ft), therefore a typical A4 sheet (1⁄16 of a square metre) weighs 5 g (0.18 oz). Place the entire ream of paper on the scale and ensure it is properly balanced. Write down the weight displayed on the scale. Cardarelli, François (2003). Encyclopaedia of Scientific Units, Weights and Measures. London: Springer. pp. 51. ISBN 978-1-4471-1122-1. A quire of paper is a measure of paper quantity. The usual meaning is 25 sheets of the same size and quality: 1⁄ 20 of a ream of 500 sheets. Quires of 25 sheets are often used for machine-made paper, while quires of 24 sheets are often used for handmade or specialised paper of 480-sheet reams. (As an old UK and US measure, in some sources, a quire was originally 24 sheets. [9]) Quires of 15, 18 or 20 sheets have also been used, depending on the type of paper.a quantity of paper being 20 quires or variously 480, 500, or 516 sheets. 2 : a great amount —usually used in plural reams of information. ream. verb. reamed; reaming; reams. Is ream a counting unit? Certain types of specialist papers such as tissue paper, greaseproof paper, handmade paper, and blotting paper are still sold (especially in the UK) in 'short' reams of 480 sheets (20 quires of 24 sheets). However, the commercial use of the word 'ream' for quantities of paper other than 500 is now deprecated by such standards as ISO 4046. [1] In Europe, the DIN 6730 standard for Paper and Board includes a definition of 1 ream of A4 80 gsm (80g/m 2) paper equals 500 sheets.
