I realise that standard letters have increased in size. C6 and B6 envelopes used to be common when I was growing up. I can remember folding a letter into 1/8 size to fit it into one of those tiny envelopes. But since Australia adopted the A4 paper size in 1974, we’ve moved more towards DL sized envelopes as standard for business correspondence. (DL envelopes are the ones that can take an A4 sheet folded into thirds). And quite often mailed items like magazines are unfolded (that is, full-sized C4 envelopes).
But for some reason, people haven’t updated their letter boxes. It’s common to see whole blocks with ridiculously small letterboxes -ones that would have struggled with two antique envelopes, let alone a DL. What do these people think as they retrieve their crumpled, wet rain on rainy days? “Hmm... I wish everyone would go back to sending tiny letters?” Do they mind that their expensive subscription magazines get trashed by being crushed? Or perhaps they enjoy going to the post office to collect any item bigger than a bus ticket?!
I’d like to remind all building developers that there is an official standard for letterboxes in Australia (AS-NZ 4253-1994 - I looked it up!). A letterbox should be 16cm x 33cm x 23cm, with an aperture (that’s a slot to you and me) of 23cm x 3cm or 33cm x 3cm. So get with the program, all you renovators and builders - put in practical and useable letterboxes and I’ll be able to sleep much more soundly!
