47 free Paper trivia questions with answers — technology quiz, new questions added Sep 2026.
Paper trivia is a tour of two thousand years of technology hiding in plain sight. A Han court eunuch named Cai Lun gets the credit in 105 CE, though Chinese fragments are centuries older; from there paper travelled through Samarkand and Baghdad to Spain and Italy, picked up watermarks in Fabriano, met the printing press, and finally switched from rags to wood pulp in the 1840s when two men on two continents had the same idea in the same year. This quiz covers the whole story: papyrus and why it lost, the first paper money and the first toilet paper, the Fourdrinier machine and why the brothers who paid for it went broke, kraft and sulfite pulping, why cheap paper yellows, how A4 is defined by the square root of two, the origins of US Letter, and the lighter side, from origami cranes and the Miura fold to the paper-plane records and the teenager who folded toilet paper twelve times. Easy questions suit anyone who has ever jammed a printer; the expert tier is for papermakers and stationery obsessives. Every answer was checked against Wikipedia's articles on paper, its history and its many offshoots, and the supporting sentence is attached to each question.

Q 01Which Han dynasty court official is traditionally credited with inventing paper in 105 CE?
Cai Lun
Cai Lun, a palace eunuch, reported his recipe of bark, hemp and old fishnets to the emperor, but paper fragments more than two centuries older show he refined the craft rather than invented it.
Q 02The word 'paper' comes from the name of which ancient writing material?
Papyrus
Papyrus lent paper its name, yet the two are unrelated technologies: papyrus is strips of plant pith pressed together in layers, while paper is pulped fibre matted on a screen.
Q 03The Egyptian writing material that gave paper its name was made from the pith of what kind of plant?
A wetland sedge
A wetland sedge taller than a person, the plant was sliced into strips of pith that were laid crosswise, pressed and hammered into a single sheet.
Q 04Before wood pulp took over in the 1800s, Europe's paper mills ran mainly on what raw material?
Discarded rags
Discarded rags, mostly worn-out linen, ran so short by the 1700s that mills advertised publicly for them, a squeeze that sent inventors hunting for a way to pulp wood.
Q 05Before paper, Chinese scribes wrote on heavy bamboo strips or on which cloth?
Silk
Silk was light but far too expensive for everyday records, while bamboo was heavy and awkward to store, and that gap is what pushed Han craftsmen towards cheap paper.
Q 06Legend says Chinese prisoners taken at which 751 battle in Central Asia taught the Islamic world to make paper?
Talas
Talas is where the tale starts, but it was first written down nearly three centuries later by the historian al-Tha'alibi, and paper had already been used across Central Asia for centuries.
Q 07Under Caliph Harun al-Rashid in the 790s, which city got paper mills so its officials could give up parchment?
Baghdad
Baghdad turned to paper, the historian Ibn Khaldun wrote, because parchment was running short and the vizier al-Fadl ibn Yahya needed far more writing material for state records.
Q 08Papermaking entered Europe from the Islamic world, taking root first in which country?
Spain
Spain got there first because much of it was under Muslim rule: mills were running at Xàtiva near Valencia in the 11th century, about two centuries before the craft reached Italy.
Q 09Which Italian town, still a famous name in artists' paper, first put watermarks in its sheets in the late 1200s?
Fabriano
Fabriano's papermakers wired designs onto their moulds so that each maker's sheets could be told apart when held to the light, and they also pioneered sizing paper with animal gelatin.
Q 10Whose printing press, built in Mainz in the 1450s, sent Europe's demand for paper soaring?
Johannes Gutenberg
Johannes Gutenberg's press produced books many times faster than hand copyists, which was only workable because paper mills had recently spread north of the Alps.
Q 11Around 1023, the government of which Chinese dynasty began issuing the world's first state-backed paper money?
Song
Song-era Sichuan ran on iron coins so heavy that merchants traded paper receipts for them instead, and around 1023 the government took the idea over and issued the notes itself.
Q 12In 589 CE a scholar-official wrote he dared not use paper quoting the Classics for what?
Toilet purposes
Toilet purposes were so ordinary a use for paper in 6th-century China that the scholar Yan Zhitui drew the line only at sheets carrying the names of sages or lines from the Five Classics.
Q 13What did the Chinese fold and sew paper into during the Tang dynasty to preserve the flavour of tea?
Square bags
Q 21Most modern paper machines are still named after which brothers, the London stationers who bankrolled the original?
Henry and Sealy Fourdrinier
Henry and Sealy Fourdrinier spent some £60,000 perfecting the machine and were declared bankrupt in 1810, so their name spread round the world with every machine sold while the fortune never came.
Q 22In the American sitcom The Office, which fictional company sells paper from a branch in Scranton, Pennsylvania?
Dunder Mifflin
Dunder Mifflin turned real in 2011, when a Staples-owned retailer licensed the name from NBC and began selling actual reams of copy paper under the made-up brand.
Q 23On a paper machine, what is the mesh-covered cylinder that can impress a watermark called?
Square bags of sewn paper trapped the scent: Lu Yu's 8th-century Classic of Tea lists a pouch of thick white paper among a tea drinker's tools, for holding freshly roasted tea so its fragrance cannot escape.
Q 14Which tissue brand was launched in 1924 to wipe off cold cream, years before anyone sold it for blowing noses?
Kleenex
Kleenex spent its first years in the make-up aisle as a cold cream remover; only in the 1930s, once buyers were reaching for it during colds, did adverts recast it as the handkerchief you can throw away.
Q 15Which company popularised toilet paper on rolls when it began marketing it in 1890?
Scott
Scott put toilet paper on rolls in 1890, yet the paper itself stayed rough for decades: in the 1930s a rival, Northern Tissue, could still make 'splinter free' its selling point.
Q 16In 1908 Melitta Bentz lined a punctured brass pot with blotting paper from her son's schoolbook, inventing what?
The coffee filter
The coffee filter grew out of her irritation with bitter grounds in the cup; she registered it with the patent office that summer and set up a company with her husband that still trades under her first name.
Q 17Watching which insects build their nests led French scientist Réaumur to suggest, in 1719, that paper could be made from wood?
Wasps
Wasps chew wood fibre into a papery pulp for their nests, and Réaumur asked why people could not do the same, yet he never tried it and mills took over a century to follow the insects' lead.
Q 18Which chemical pulping process, the world's most widely used, makes the tough brown paper of grocery bags?
Kraft
Kraft means 'strength': the pulp comes out stronger than its rivals', which is why it is left unbleached for brown bags and parcel paper, and the process can even digest resinous pine.
Q 19Which substance, left in the pulp by mechanical pulping, makes newsprint turn yellow and brittle with age?
Lignin
Lignin is the natural stiffener in wood, and cheap mechanical pulping leaves it in; chemical pulping strips most of it out, which is why a book page stays pale while a newspaper browns in the sun.
Q 20In 1917 Hallmark's founders ran out of Christmas tissue paper and sold fancy French envelope linings instead, launching which product?
Gift wrap
Gift wrap began as a stopgap: the linings, priced at 10 cents a sheet, sold out as fast as the tissue had, and within a few years the Hall brothers were printing decorative paper of their own.
A dandy roll
A dandy roll carries a raised wire design that presses into the wet sheet and thins the fibres, so the pattern glows when the page is held to the light, just as wires sewn onto a hand mould once did.
Q 24Which handmade Japanese paper, usually made from mulberry bark, do museums worldwide use to mend torn books and artworks?
Washi
Washi gets its strength from bark fibres that are pounded and left long rather than chopped, so even a tissue-thin strip pasted along a tear will hold a fragile page together.
Q 25The rough, feathery border on a sheet of handmade paper is known as what?
A deckle edge
A deckle edge forms where pulp seeps under the deckle, the wooden frame that fences in the wet sheet; once an unavoidable flaw, it is now faked on machine-made paper to make books look handmade.
Q 26A4 paper was born in 1922 as part of a national 'DIN' standard for sheet sizes in which country?
Germany
Germany adopted engineer Walter Porstmann's system to end a jumble of competing sheet sizes and cut the cost of stocking paper, and other countries copied it until it became the world standard.
Q 27What is the aspect ratio of every sheet in the A series of paper sizes?
√2
It means a sheet folded in half keeps the same proportions, a property noted by Georg Christoph Lichtenberg in 1786.
Q 28What is the area of a sheet of A0 paper?
1 square metre
1 square metre is the starting point of the whole system: each size is half the one before, so an A4 sheet is a sixteenth of a square metre and a sheet of standard 80-gram office paper weighs 5 grams.
Q 29Which newspaper format takes its name from a brand of compressed medicine pills trademarked in the 1880s?
Tabloid
Tabloid was the drug firm Burroughs Wellcome's trademark for its small pressed pills, and by about 1900 the word had jumped to newspapers that served the news in similarly condensed doses.
Q 30What are the dimensions of US Letter paper?
8.5 × 11 inches
8.5 × 11 inches became the US government's own size only around 1980: for nearly sixty years federal offices used a smaller 8 × 10.5 inch sheet that Herbert Hoover had prescribed as commerce secretary.
