A3 - what the heck is A3 anyway?

I read about folks printing at different sizes - "...if you print up to A3 you'll be fine..."

What are the sizes and corresponding codes?

I'm used to thinking in 4" x 6", 5" x 7", 8" x 10", 11" x 14" etc. - A3 hurts my head...

Take 2 Aspirin and read this. "A" print sizes are used about everywhere except our good ole USA.

Hopefully this will explain it for you.

Hmm, thinking in first 4" x 6" and then in 8" x 10" make my heart bleed. Don't you keep the aspect of ratio when going to a bigger paper (whatever those """" signs means, I mean)?



Yes, the planet would benefit from Esperanto and common units.

Any search engine can provide you with a nifty table, btw. Save the aspirin for occassionally pattern noise instead.

The " symbol means inches - so, 8 inches x 10 inches - it's a standard North American print size. More common, though, are the 4"x6" and 5"x7" sizes.

I'm off to check out the wiki - thanks gang!

...at least no one said, "A3? It's the smallest Audi in North America."

I think I see my confusion - these A sizes appear to correspond to actual paper sizes - so paper for printers, for example.

I send all my images to a photo shop for printing on photo paper in standard photographic sizes.

OK - I'm starting to see it - printing up to the A3 size is good, then - that's a big picture.

Hate to step on that thought. Our 8 1/2 X 11, 11 X 17, etc. paper is not the same as their A sizes. Have received some correspondence on A size sheets and I believe they are narrower than what our standard paper sizes come out for our machine printing. A3 is a big picture, just not one we use here.

What makes the A sizes easy to understand and use is the folding in half principle (As close as possible). A0 is 841 x 1189. Fold it in half and you get A1 594 x 841. Fold in half and you get A2 420 x 594 and so on.

Cheers

Thanks Eddie. At least if something is printed on an A series it has more relationship to actual vs. trying to divide a 4X6 into an 8X10 or an 11X14. Makes one wonder how we ended up with these 'interesting' sizes. Anyone got a clue as to the history?

A4 is what you are talking about: slightly narrower and a bit taller than Letter size, which is standard paper size for office use in Europe.

A3 would be double A4 (thus similar to double Letter size, as a reference).

and Canada unfortunately. Having worked in Europe for several years, it really is better to refer to A sizes. They don't have Full-scap size and their business cards are an odd shape compared to ours. When I have to produce reports for them I need to make sure to remember "their" A4 size otherwise its a complete mess.

I thought the US had the Metrication Act of long ago to finally bring you guys up to date? Following from Mingdie - A4=210mmx297mm (why they didn't make it 300mm has always had me rattled!)

Arpe.
The start is A0 which is 1 m2. How they came up with the lenght and width see below.
The largest standard size, A0, has an area of 1 m˛. The long side of the sheet is calculated by taking the 4th root of 2, approximately 1.189, and the short side is the inverse of that number, approximately 0.841, and multiplying by one metre.

Easy

Cheers
