Talk:ISO 216

Merge Silver rectangle into ISO 216?

I propose the merger for two reasons:

There is little that can be said about silver rectangles. Unlike golden rectangles, which are alleged to crop up everywhere and have a distinguished history, silver rectangles are of limited interest. The folding property should be described at ISO 216 anyway.
The name "silver rectangle" is both ambiguous and unfortunate. It is unfortunate because it is not a rectangle with the proportions of the silver ratio, as is suggested by the golden ratio/golden rectangle analogy. It is ambiguous because it is sometimes defined by root2 and sometimes by 1+root2 (the silver ratio), and there are not enough references to determine which is more common. I think the solution is to endorse neither, but to acknowledge in both ISO 216 and Silver ratio that they both have some claim to the name "silver rectangle".

I think this is a good idea rafael.cosman

Okay, I'll get on it. Melchoir 04:18, 24 March 2006 (UTC)[reply]

Done. Rather than redirect Silver rectangle to either usage, I've made a somewhat unorthodox disambiguation page out of it. Melchoir 04:33, 24 March 2006 (UTC)[reply]

Inches

I propose that someone add inch equivalents to these measurements because Americans can't just see a measurement like 200mm and know how long that is. 71.227.254.181 23:57, 2 November 2006 (UTC)[reply]

Why single out Americans for special treatment? This is an international English encyclopedia.

Although I'm all for making Wikipedia as accessible as possible, I must admit that I can't seem to muster any compassion for someone who doesn't know what a mm is. Shinobu 09:46, 16 November 2006 (UTC)[reply]

Let them have their inches. I can relate to the frustration, as everytime I come across an imperial measurement, I need to use google to convert it into something I can cope with. Hence, I usually add change it to SI units with imperial units in parenthesis when I come across it; no reason why we shouldn't add imperial units even when they're not present. The absence of a dual standard can make people campy about it, leading to articles that are either useless to Americans and akward for older Brits, or articles that are useless to the rest of the world.

Question: should the inch equivalents be based on the A4 rounded measurements or the formula? Using the formula there is a difference (due to a rounding error) for a few of the inch values. Jw6aa 03:47, 12 February 2007 (UTC)[reply]

Answer: From a practical point of view, the inch equivalent should be based on the final measurements, not the formula. The ISO 216 is not for theoretical use but for printing and the like, where the final page size is all that matters in the end. - Tommi Kovala (unregistered user) 10:38, 21 March 2007 (GMT)

Why two duplicate tables

The table on the left should be deleted. The lower table is really very nice, but the drawings should be scaled consistently. jcp 05:38, 5 April 2007 (UTC)[reply]

Mistakes??

I'm pretty sure that the side parallel to the shorter side is another one of the shorter sides. I think probably perpendicular is what is meant.
