A Standard Letter is any closed item of rectangular shape made of opaque paper weighing not more than 20g and satisfying size restrictions as well as address location specifications outlined below.
Transparent paper may only be used for the transparent panel and the addressee's address is the only thing visible through the panel. Standard letters may not contain any rigid objects or objects causing protrusion. In addition, a letter may qualify as standard letter only if it meets special addressing criteria laid down for the machinable mail. This is the reason why the postage for standard letters is cheaper than the postage for ordinary letters of the same size.
