Watch How 80 million Toilet Rolls are Manufactured In A Day
Toilet Paper Roll Dimensions and Guidelines (with Drawings)
The layers are bonded together using lamination, and the more layers there are in a sheet, the thicker and more comfortable it will be. The ply will affect how many single sheets are on a roll of toilet paper, and some people think this will affect how long a single roll lasts, but actually, this is not the case.
This means that despite containing fewer individual sheets, toilet rolls that are double or triple ply are no less economical than single-ply. With a toilet roll that is triple-ply, you can expect to have around 333 sheets on each individual roll of toilet paper, but you will only require a third of the number of sheets on each toilet visit that you would ordinarily use with single-ply, and therefore the roll will last you the same amount of time as usual.
The standard length of the cardboard tube you will find inside a toilet roll is 3.7 inches, but it can vary between manufacturers, with some brands of toilet roll having a length that is closer to 4 inches. This is the equivalent of around 10cm in length, or a little over, depending on the brand you have bought.
On average, the typical consumer will use between 10 and 20 sheets of single-ply toilet paper on each visit to the toilet, and the average person makes four to five visits to the toilet each day. This means that as many as 100 sheets will be used by one person in a single day.
From this, you might deduce that a roll of 500 sheets is only going to last half the time of a 1000 sheet roll, but actually, because the sheets are double-layered, you will end up using much fewer sheets. For example, if a person usually uses 12 sheets at a time with a single-ply toilet roll, then they will only need to use 6 sheets at a time with a double-ply toilet roll to achieve the same level of thickness.
