Kommentarer

Om du mäter marginaler i millimeter multiplicerar du marginalbredden du vill ha i millimeter med 3,937 för att fastställa rätt mätning i hundradelar av en tum. Om du till exempel vill ha en marginal på 25 mm multiplicerar du med 3,937 och resultatet är 98 när det avrundas nedåt. Sedan anger du lämplig Margins medlem till 98.
