Engineering drawing frame border size

The size of the drawing border (or Engineering Drawing Frame) on your technical drawings is covered in BS EN ISO 5457.

The BS ISO standards  require a 20mm border to the left hand edge (for filing) and a 10mm border round the other three sides of the drawing sheet.
