DL envelope
220 × 110 mm
220 × 110 mm — fits A4 folded into three.
The commonest business envelope outside North America. It takes an A4 sheet folded twice into three, which is why the fold is standard on letterheads. DL is not part of the A or B series despite being used with them — it comes from the older German DIN Lang format.
