About paper tissue napkins
Paper tissue napkins normally come in three sizes:
40cm dinner napkins, 33cm lunch napkins and 24cm cocktail napkins.
These are normally supplied folded into four and these are called “4-fold” napkins or serviettes.
If they are supplied folded once more into a rectangle this is called “8-fold”. These are used by hotels and restaurants because cutlery can be tucked inside.
