just learned americans have different standard paper sizes than everyone else. what do you MEAN you don’t have A4 as the standard. what do you mean your standard paper size isn’t even the same size as an A4. apparently it’s like. ’letter’ and ’legal’ and whatever else. help!!!
this is so scary
That has to be false. That's misinformation hold on
holy fucking shit
So I work in engineering; and always wondered who used these weird “A” sizes I’d see in large printer settings that I’ve never seen any company even have paper in stock for. Now I know.
And now I have to be one of those obnoxious US Americans because WHY THE FUCK WOULD YOU USE THESE WEIRD UNEVEN DIMENSIONS!? Even in metric most of the “A” settings are an annoying ratio! 210x297mm? 594x841mm!? What’s the point of using such small units of measurement if you’re not going to make sensible sizes!?
because the largest standard paper size is A0 which is exactly one square metre of paper with an aspect ratio of the square root of two. this gives us a nice simple measurement of area for the paper as well as allows us to do the halving/doubling magic. A1 is 0.5m², A2 is 0.25m² etc.
The halving/doubling magic that psychaun refers to is the fact that you can get each paper in the series by cutting the previous one in half. I fold some A4 paper in half, I have an A5 booklet. I tape two A4 pieces together along their long side, I have an A3 piece. Each piece of paper is half the area of the previous and half the width of the previous' length with a length the same as the previous' width. The aspect ratio is exactly the same for every size. This makes it very easy to resize things, fold things inside each other, and calculate the size of paper you've never used before based on its name. "I can resize this to fit any other paper size because the aspect ratio is identical," "I can fold a standard size in half to get the next standard size down" and "the area I'm working with can be multiplied up to fit into a metre squared without any messy fractions of leftover paper" are all far more practical considerations for a paper size than "the millimetre length of this paper size isn't a round number".
fyi there are also B sizes in paper, which fit in between the A sizes - less often used but good for book covers and stuff
a Bn size is the mean between An and An-1
and then C sizes for envelopes, such that a C4 envelope fits an unfolded sheet of A4 etc
Reblogging because this is something I find interesting.
Also because it’s another example of how the United States has to do things differently—to its detriment.
This is a bad take, friend.
The US doesn't "have to do things different" for the sake of doing things differently, as your words imply, nor is the sentence above about who uses what paper fully correct, either*.
The reason that the US (and Canada, most of Central America, Chile, and the Philippines) use different standard sizes* from Europe is probably pretty easy to figure out when you think about things like "there's a big fucking ocean between two of those places, but not between all of the countries in Europe."
The standard size of paper, according to the American Forest and Paper Association, comes from the days of manual paper-making, and their assertion that 44" is about the length of the average experienced vatsman's comfortable grasp. So a sheet is 1/4" that length. The US standardized its own paper according to what legacy equipment it had, and keeps those standards because even today, paper tends to not be shipped back and forth between Europe and the US unless it has to be, because paper and books are really fucking heavy, so why should either one of us change our standards? Doing so would require massive amounts of capital investment, and frankly, we like our paper sizes just fine. It's really not to our detriment at all. We don't really import a lot of paper, and in fact, we export a lot of it.
American paper sizes are also half of each previous size, it's just that our base is a rectangle, not a square, uses imperial measurements, and reaches back to measurements based on manual paper-making. Sure, we could spend billions of dollars changing our standards to meet that of countries that don't supply us with this good, creating a massive amount of industrial and consumer waste as everything from paper manufacturing mills and industrial printing presses to plastic binders and hole punches at schools all become garbage, but... why? We also use different standard sizes of snack food bags, based on how our industries developed, but there's no actual reason for those things to be standardized, so why, exactly, should they be? Because it bothers someone who doesn't use our machines and didn't know until today that it was different? That's not a real reason. That's just "haha the US sucks and is dumb and irrational."
No, it's actually super fucking rational when you remember that most European countries are smaller than US states, and we're standardized across the places where paper actually moves back and forth in massive bulk on a regular basis. You know: our own states, and Canada, and not Europe, on account of this being a huge fucking continent and paper being incredibly heavy and expensive to transport across oceans. That's why it's governed by the American National Standards Institute, which also governs or governed stuff like thread standards for nuts and bolts & exposure standards for film. The latter had the ANSI standard become the ISO standard, which is a great example of technology which was developed more recently and more specialized and thus not so deeply rooted and hard to change being much more possible to standardize.
tl;dr: all industrial standards like paper sizes have valid and long-argued reasons why they're like that, and unless you're coughing up the solution for changing something with hundreds of years of built-up infrastructure without breaking all of the industries that depend on that standard, the cash to do it, and the reason why all the old equipment that can't be converted should become garbage... fuck off, man, and leave us alone. There are real problems in the world, go solve those.
*While many Mesoamerican countries have officially adopted ISO standards, ANSI standard paper is most commonly in use day to day.
This is really interesting!
Genuine question: if the US somehow switched to metric measures, would that prompt the need to change the paper sizes in any way? I would think ‘no’ but I’m sure there are elements I’m not thinking about.
1. We're not gonna.
2. No.
is being arrogant and thoughtless an American kink or something?
Do you really think America is so isolated that it gets to uniquely ignore the rest of the world?
Explain fucking Australia then?
Who isn't in Europe? Who is actually a continent, with no land borders unlike America. Who, much to my annoyance, has been more economically tied to the US than Europe since WWII (and its own neighbours since long before that). Who suffered a century of using American typewriters with American sized paper. Who also has their own paper industry like quite a lot of the world (though which still uses predominantly American designed and built machines) that creates massive kilometres long rolls of paper, like the America industry, that isn't limited by the length of someone's arm and is chopped down later.
Even with all those similarities we managed to switch to DIN 476 in 1974, the year before ISO 216 was created, along with a whole list of other countries that also aren't in Europe and also have massive ties to US industry (Japan 1951, Israel 1954, NZ 1963). We even have American made home and business printers that normally work with ISO paper seemlessly but get confused when we print a document made by Americans.
Also the UN switched in 1975. You know the big bureaucratic organisation that uses a lot of paper and functionally exists solely in New York. It can somehow get standardized paper while dealing with American industry.
This isn't a rant about paper. It's about American exceptionalism.
You literally answered all of your own questions, jackass.
Quite a lot of speciality industries outside of America still use their own old imperial measurements too.
Watercolour paper and most art papers are still sold in subdivisions of the big old arm width standard (called double elephant) in the UK, Japanese printmaking paper has the Hosho sheet and its subdivisions. I'm pretty sure newsprint still comes in its own formats etc. etc.
Anyone who's a big paper fan should look up their most local paper mills. There's probably cool paper being made somewhere near you. You too can experience the delight of a double elephant.
British Broadsheet paper size is 14.76 × 23.5 inches (375 × 597 mm / 37.5 × 59.7 cm). Get exact British Broadsheet dimensions for printing,
Check this shit out! Newspapers and Broadsheets are the opposite of universal, even in countries that use the Metric System.
