Frequently Asked Questions

Here at Mondi rotatrim A4 paper is our thing. Not only have we been here since 1967, but we’ve got over 250 000 hectares of plantation that we manage sustainably. So it stands to reason that we’ve picked up some great facts about A4 paper along the way.

Paper facts

  • An A4 page is sized 210 x 297mm.
  • When is A4 paper cut in half, the resulting sheets (A5) have the same proportions – ratio of height/width. That way printing can be scaled up or down for different size pages without changing the layout or appearance of the page.
  • The standard-sized paper sheet in the western world (A4) is based on a factor of √2. The reason for this is so if you fold it lengthwise every time, it maintains the same length-to-width ratio, large or small. This means that folding an A4 piece of paper in half gives you A5, folding an A5 in half gives you A6 and so on. Conversely, if you put two pieces of A4 together, you get A3.
  • If you could theoretically fold an A4 piece of paper 103 times, the thickness would be larger than the observable universe, but in terms of surface area would be smaller than an atom. The current world record for folding a sheet of paper in half is 12 times – but it wasn’t an A4 sheet, so we’ll leave you to try to get beyond 7 folds.

Packaging it all up

  • A paper ream is a pack of paper that usually contains 500 sheets per package.

  • A4 office paper boxes come in 5 reams. A box weighs an average of 12½ kg. Divide that by 5 and you get 2½ kg per ream.
  • How many boxes of paper in a ton? Most bulk paper orders have a minimum buying requirement of 1 ton. This is usually made up of 80 boxes transported in pallets. 1 pallet = 80 boxes of paper = 1 ton.
  • If you stand 313 A4 sheets in portrait mode, they’ll stack as high as the Statue of Liberty. And standing 192 sheets in portrait mode would be as high as the Tower of Pisa.
  • On average one pine tree can make 80 000 sheets of paper.
  • Paper is one of the few truly renewable resources. Paper fibres can be recycled up to 12 times before they get too short for paper-making.
