In bookmaking, the quarto sheet would be folded twice. This is to create four "leaves".
A book made with this method will normally be eight pages.
These days it is more commonly used with pamphlets.
Four.
Any size sheet of paper can only be folded in half 7 times.

Perhaps Quarto is a girls name in some areas (I do not know that it is so) bur it IS a size of paper or book!Quarto (abbreviated 4to or 4°) is a book or pamphlet produced from full 'blanksheets', each of which is printed with eight pages of text, four to a side, then folded two times to produce four leaves (that is, eight book pages). Each printed page now presents as one-fourth size of the full blanksheet.
The International Standard for paper sizes defines A0 as a sheet of paper that has an area of 1 metre2 and whose length is sqrt(2) times its width. So A0 is approx 841mm*1.189mm.A1 is the size of an A0 sheet folded in half lengthwise: 595mm * 841mmA2 is the size of an A1 sheet folded in half lengthwise: 420mm * 595mmA3 is the size of an A2 sheet folded in half lengthwise: 297mm * 420mmA4 is the size of an A3 sheet folded in half lengthwise: 210mm * 297mmThe size of an A4 sheet is 0.0625 metre2 or 2-4metre2.If you took 2x sheets of size Ax you would have 1 sq metre of paper.
It is hard to explain, but it basically amounts to the size to fold ratio. A large enough, thin enough, sheet of paper can be folded more than eight times, but it has to be the size of a football field in order to do it. 128 layers of paper is a lot to fold in half to get to 256!
Everything was done by hand. The printing press won't be invented until the 1446.
Any paper can be folded in half for 6 times.
the rules of matter will only allow it to be folded 7 times max
If by sides you refer to the number of paper slices you can hold then the formula is this: assuming that when the paper has not been folded, the number of times folded is equal zero then the equation is: 2x, where x is the number of times folded. for example if the paper has been folded four times the number of sides is: 24 = 16
A katana is typically folded around 10 to 16 times during the forging process.
