FOLDING TECHNICAL DIN-A DRAWINGS

There are basically two ways to handle large format drawings: roll them or fold them. Folding has a number of advantages:

• a folded drawing is easier to archive and takes less space

• a set of folded drawings is conveniently organized in a ring binder or file folder, easy to slip in a briefcase to bring along to meetings

• a set of folded drawings in a binder/folder can be paged through without unfolding, because the title block is always visible in the lower right corner

• once you have flipped through the drawings and found the one you wish to view (or present), a folded drawing is easily unfolded to its full size without first needing to remove it from the binder/folder

• a folded drawing, put in an envelope, is cheaper to send (by post) than a rolled-up drawing in a cardboard tube

There is a catch: you need to fold the drawings correctly and for the big drawings is not so easy.  The folding procedure that I present here conforms to the DIN 824 standard, based on "A" paper sizes. Each page folds to A4. I present how to fold A3, A2, A1 and A0

DIN A3: 420 × 297

DIN A2: 594 × 420

DIN A1: 841 × 594

DIN A0: 1189 × 841

The world standard technical paper size is DIN 823 and ISO 216 compatible -"the A series". Except for some countries as EEUU and Canada that uses the standard US-Letter
