Quilt for one person :

The size per default for a bed one person is 140x200, but in order to have more ease and better fallen off the quilt around the bed, you will have to opt for the quilt 200x200. 

For a bed size of 120x190 of 120x200, the perfect size is 200x200.

Quilt for 2 persons :

For a standard bed 2 persons, the standard dimension is 220x240 to have a sufficient cover on your bed.

For a sofa-bed; or a flat mattress on the floor, we recommend you to buy the quilt 200x200 to decrease the risk of the quilt to rub the floor.
