Technical Drawing Standards: Border size


The size of the drawing border (or ‘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.
