How much does a sheet of A4 paper weigh?
5 grams.The weight of 1 sheet of A4 paper (210 x 297 mm in size), with a density of 80 g / m 2 (office paper) is 4.9896 g (0.004896 kg).
How to find out the mass of one sheet of A4 paper?
The first thing that comes to mind is to weigh 1 A4 sheet. We need scales, preferably more accurate, for example, jewelry or laboratory scales, in which the weighing accuracy is 0.1 g or 0.01 g and 1 sheet of paper.
Not every citizen of our fertile country has a jewelry scale yet, so you can take kitchen scales, canter scales, floor scales for weighing loved ones, etc., which are found in the house. But, because you won’t be able to weigh 1 sheet of A4 paper on them, you will have to weigh a certain number of sheets.
Take 100 sheets, 500 sheets - a pack of standard A4 paper, or several packs - 2 packs = 1000 sheets. Weigh this Nth number of sheets of paper and then divide the mass by N.
Another way to find out the same weight of this sheet of paper, let's call it - mathematical.
So the assignment is:
sheet width - 210 mm or 0.21 meters
sheet length - 297 mm or 0.297 meters
paper weight - 80 g per square meter
Solution:
1. calculate the area of a sheet of A4 paper - multiply the width by the length of the sheet: 0.21 m x 0.297 m = 0.06237 sq.m.
2. Calculate the mass of a sheet of paper with an area of 0.06237 sq.m: 0.06237 sq.m x 80 g = 4.9896 g.
Answer: the mass of 1 sheet of paper with a density of 80 g / m 2 is 4.9896 g. We round it up and get - 5 g.
One of the most popular questions about paper is its weight and cost. Indeed, like any other or Xerox is quite heavy - one pallet is over 600 kg! When buying a large consignment, it is logical to provide for the issue of delivery around the city and loading and unloading. One box weighs about 12 kilograms, enough weight for women's hands, and the lack of an elevator in the organization can aggravate the ascent to the floor. Today, the document flow is necessarily carried out on paper and, most likely, one should not expect changes in this matter. We recommend that you use paper more prudently, for example, two-sided printing results in significant savings on your paper resources. It is possible to use corrupted copies as drafts. We once again present the most important figures for you, dear colleagues:
How much does Svetocopy A4 weigh?
A4 format:
- One A4 paper pallet = 240 packs or 48 boxes; weight 600 kg; volume 0.92 m3
- One box = 5 packs of 500 sheets; size 315 mm x 222 mm x 270 mm
- One box A4 = 12.5kg
- One pack of A4 = 2.5 kg
A3 format:
- One A3 pallet = 120 packs or 24 boxes; weight 603.84 kg; volume 0.86 m3
- One box = 5 packs of 500 sheets; size 420 mm x 297 mm x 270 mm
- One carton A3 = 25.1kg
- One pack A3 = 5kg
Using paper sheets in different formats for people living in the 21st century is like waking up every day and brushing your teeth. Few people know that at the beginning of the 20th century there were no standards for what a piece of paper should be for writing reports, reviews, or just keeping a home notebook.
A4 sheet history
In the twentieth century, which were used for work, each firm, factory or any other production chose for itself. Creative people at that time preferred to work with paper, which had the name "Golden Section".
The ratio of the sheets of this line was 1:1.168. However, it was not quite suitable for other industries. The first to propose a single standard for the format of sheets of paper was the German Walter Portsmann. He gave life to sheets whose aspect ratio was 1:1.414, and the total area of \u200b\u200bthe sheet was one square meter.
A4 sheet dimensions
How much a sheet of A4 paper weighs and what size it is, not everyone who uses such paper knows. Sheets of this format have exactly the same size. It is one sixteenth of a square meter. Diagonal sheet A4 is 364 mm.
This sheet was obtained by folding A0 paper in half. By the way, these days A0 is almost forgotten. Occasionally it is used for wall newspapers in schools or kindergartens.
So how much does an A4 sheet weigh?
It would seem that getting an answer to this question is very simple - put the sheet on the scales and you know the answer. However, not all scales are able to show the weight with an accuracy of 0.01 g. Many who consider themselves a savvy person put a package of paper on the scale and weigh it, then divide by the number of sheets and think they will get the right answer.
However, the weight of the package itself must also be taken into account. Therefore, in this case, you need to take sheets without a wrapper, and the answer will be more accurate.
When weighed on a more accurate scale in order to find out how much an A4 sheet weighs, it was found that its weight is 4.9 g. Accordingly, a package of such sheets in the amount of 1000 sheets will weigh 4.9 kg. Some sources claim that the weight of an A4 sheet is 5 g. It is important to take into account the fact that A4 sheets can have different densities. The weight of 4.9 g has a standard A4 with a density of 80 g per square meter.
The history of this invention of mankind has not been thoroughly studied. Because in today's world, few people delve into such details and moments. Most of us take everything for granted, and sometimes even neglect certain human achievements, while other people living in poor countries are not even aware of some of the benefits of civilization.
The weight of one sheet of A4 paper with a normal weight of 80 g/m2 is about 5 grams. The dimensions of an A4 sheet are 210 x 297 mm, and diagonally 364 mm.
Paper is one of the most popular office materials used in huge volumes every day. Contracts, invoices, estimates and invoices - to print these and other important documents, a lot of standard A4 sheets are spent, completed in bundles. And how many photocopies are made during one "office" day! And it's hard to count. So how much does an A4 sheet weigh? Of course, they think little about it - rather, the question will arise about the mass of one ream of paper. So, today we will consider this topic in more detail, and also learn a lot of interesting things about paper.
The weight of one sheet of A4 paper with a normal weight of 80 g/m2 is about 5 grams.
A bit of "paper" history
Paper was first used for writing in ancient Egypt. True, it was not quite paper in the usual sense, but its "prototype" - papyrus. This was the name of the reed that grows in abundance along the Nile River. Light, thin and extremely easy to carry, papyrus served as an excellent raw material for making writing sheets.
But the ancient Chinese paper production is more like a modern way. According to legend, the idea to make paper from the pulp of the mulberry tree belonged to the official of the Chinese court of the Han Dynasty - Cai Lun, in 105 AD.
In Europe, paper production began in Spain in 1120. Linen and hemp rags served as the material for the manufacture, from which excellent thick white paper was obtained. Over time, the need for paper increased greatly, which led to the need to increase production volumes. Therefore, crushed wood was added to paper, which was later treated with caustic soda to produce cellulose. This method of paper production is still used today.
How much does one sheet of A4 paper weigh?
The weight of a standard A4 sheet depends on the weight of the paper. Let's look at the relationship between these indicators with the help of the following table.
As you can see, the mass of a paper sheet is directly proportional to its density. For letters, forms and other documentation, A4 sheets with a density of 80 g / m2 are most often used. So the approximate weight of one pack of office paper of this format (a set of 1000 sheets) will be approximately 5 kg.
How much does one A4 sheet weigh - methods for determining
With the help of special scales. To do this, it is better to use jewelry or laboratory scales with a weighing accuracy of 0.1 or 0.01 g. However, due to the lack of such a device, you can resort to ordinary kitchen scales. In this case, you should weigh a stack of A4 paper, complete with 500 or 1000 sheets. The resulting mass is divided by the number of sheets in the pack.
With the help of mathematical calculations. Here you need width, length and density. First, we find the sheet area - 0.21 m x 0.297 m = 0.06237 m2. now we calculate the mass by multiplying the area by the density - 0.06237 m2 x 80 g / m2 \u003d 4.9896 g. Thus, the weight of one A4 sheet is 4.9896 g, which can be rounded up to 5 g.

- As part of paper, 85% is cellulose, which contains complex carbohydrates. So the paper is quite edible.
- How many times can a sheet of paper be folded? No more than seven. However, the American schoolgirl managed to do it as many as 12 times - with the help of certain mathematical calculations.
- Until the 18th century, the produced paper had a brownish-yellow color, which negatively affected the reader's vision. With the discovery of chlorine, paper acquired a white color, which means it became “safe” for the human eye.
- One financier or lawyer can “fill up” about 20 tree trunks a year.
- According to psychologists, it is best to read in the toilet. In this regard, many manufacturers produce paper for "toilet" reading - with jokes and other literary works printed on its surface.
Now we know how much a sheet of A4 paper weighs, how to calculate it, as well as many interesting facts about this amazing material.
This is a boring and informative post. It is dedicated to the ISO 216 standard - the one that describes paper sizes (A series, B series, C series). Recommended for reading: designer, layout designer and all inquisitive people in general.
So let's go:
What does this standard govern? It describes the dimensions of everyday paper - from your new European passport to the wall newspaper in the school corridor (everything in this world is for a reason :). Knowing the principles of building a paper sheet of the ISO 216 standard, you can calculate in 15 seconds how much A4 paper will be needed for pasting Red Square, how much this paper will weigh and how many cars will be needed to transport these sheets :)
Each sheet of ISO 216 paper has a width equal to the result of dividing its length by the square root of two (1:1.4142). As a result, if we cut such a sheet in half along the larger side, then we will get a sheet of paper with the same proportions - two A4s side by side, this is A3, and an A2 format sheet in half, this is A3. Unclear? Look at the picture-
The general field is the size of A0. Its area is one square meter- it is important! Therefore, if we take an A4 typewritten sheet, then its area is 1/16 of a square meter. Do you feel what kind of sabotage can be carried out in this way? Example:
Suppose the area of the central square of Uryupinsk is 200,000 square meters. It is necessary to put it before the elections with leaflets "Zhirinovsky - for president!". We count! 200,000 square meters, this is 6400 packs of A4 paper (1/16 sq / m) of 500 sheets (200,000 meters multiplied by 16 and divided by 500). We all know that the weight of such paper is 80 grams one square meter. 80 divided by 16, we get the weight of one sheet of A4. Multiply by 500 is the standard pack size. Total-2.5 kilograms. Great! We multiply 2.5 kilograms by 6400 packs, we get 16 tons. Truck with a trailer :)
Or another example - Natasha mozgovaya decided to secretly cut out and hide the page with her new article - not yet on the shelves, but already printed in the newspaper, whose circulation is hidden in a secure warehouse. The newspaper has a circulation of 20,000 copies. Newspaper format - A2. We take a calculator and start helping Natasha - A2, this is 1/4 of one square meter. The weight of ordinary newsprint is 60 g/m2. Multiply by 20,000 and divide by 4. Phi. All pages with Natasha's article weigh 300 kilos. With an average density of 0.7-0.8 grams per cubic centimeter, everything will fit in a hatchback (body type, like the fourth Zhiguli model) and there will still be room for Natasha herself and an accomplice (just kidding :).
In addition to the usual A-x series for us, there are formats of series B and C. Formats B are most often used for book products, series C, for envelopes in which sheets of series A are inserted. After all, C4 is just a little larger than A4 (10 millimeters on each side). Let's look at the table-
| Formats A-Series |
Formats B-Series |
Formats C-Series |
|||
|---|---|---|---|---|---|
| 4A0 | 1682 x 2378 | ||||
| 2A0 | 1189x1682 | ||||
| A0 | 841 x 1189 | B0 | 1000x1414 | C0 | 917 x 1297 |
| A1 | 594x841 | B1 | 707x1000 | C1 | 648x917 |
| A2 | 420x594 | B2 | 500x707 | C2 | 458x648 |
| A3 | 297x420 | B3 | 353x500 | C3 | 324x458 |
| A4 | 210x297 | B4 | 250x353 | C4 | 229x324 |
| A5 | 148x210 | B5 | 176x250 | C5 | 162x229 |
| A6 | 105x148 | B6 | 125x176 | C6 | 114x162 |
| A7 | 74x105 | B7 | 88x125 | C7 | 81x114 |
| A8 | 52x74 | B8 | 62x88 | C8 | 57x81 |
| A9 | 37x52 | B9 | 44x62 | C9 | 40x57 |
| A10 | 26x37 | B10 | 31x44 | C10 | 28x40 |
Here is a trifle, the size of the paper. But how convenient! The sheet is always placed in an envelope, bookshelves are sharpened to A4 - A3 - A2 heights, libraries buy one stapler for all magazines that use ISO formats, there is almost no paper waste in production - all book sheets are stacked without gaps on a proportional B-series large format sheet Since all sheets are proportional, increasing A4 to A3 on a photocopier still fills the entire sheet. Formats have entered our lives so imperceptibly that you didn’t even notice - even your mouse pad succumbed to the trend and took on the size of B5 (at least mine :).
By the way, in some cases, they allow the use of unusual aspect ratios. Example - there are envelopes that are 229mm wide (like C4) but 108mm high (1/3 of 324mm). In such an envelope, an A4 sheet is placed folded in three.
By the way, printers see paper a little differently:
| RA Series Formats | SRA Series Formats | ||
|---|---|---|---|
| RA0 | 860x1220 | SRA0 | 900x1280 |
| RA1 | 610x860 | SRA1 | 640x900 |
| RA2 | 430x610 | SRA2 | 450x640 |
| RA3 | 305x430 | SRA3 | 320x450 |
| RA4 | 215x305 | SRA4 | 225x320 |
See? Almost similar to series A. Margins in 5 mm SRA format, cut off after printing. And we get our usual A compatible format. On the margins, usually, all the necessary technological marks and other nasty things are printed.
To be continued....
