It's a question we often get asked, so we thought we'd put pen to paper! The number of Blum Hinges that you'll require depends on the height and weight of the door.
Blum's recommendations are based on a standard door that's 600mm wide, so if your door differs from this you may want to consider a trail application.
As a rule of thumb each hinge has a weight loading of 3.5KG each.
To achieve good stability, hinges should be spaced out as far as possible.
