What is ARCH E size?

[AFDrafter]

I'm in the Air Force and while reviewing our training material I noticed they stated that Architectural E size paper is 30"x42". On the civil circuit I was taught ARCH E was 36"x48" and the other sheet sizes, D-A, were based on those dimensions in proportionatly smaller sizes. So my question is, Which is it? 30x42 or 36x48? Thanks in advance for your guy's help.

Basically, if you have an E size, you fold it in half, and you have a D size. Fold that in half, you get a C size. Fold that in half... well you get the idea.

After all that is said and done, I can't help you with civil though

You see, this is what I was taught as well. But our Air Force training books say Architectual E size is 30x42 and has said that for the last 10 years. Soooo, either they have been wrong all along, they use a different Architectual Standards system (which contradicts its name), or thats some other kind of "alternate" E size.

In the UK

Arch E is 36x48
Arch E1 is 30x42
Arch E2 is 26x38
Arch E3 is 27x39

Hope that helps.

I agree with smcadman.
But, I did find the following:

The USAF has different standards than the rest of us.

I thought DoD was standardizing on/with ASME?

Have you read faq731-376 to make the best use of Eng-Tips Forums?

Arch F is 30 X 42.

DoD is standardizing with ANSI D and ISO A1.
