Voted for A5 in preset size.

same here. another reason to get annoyed with Ai for years, can u guys fix up all these little annoying things?

Yes, thoroughly agree but also please make it easier to change the presets units to eg millimetres too! Who honestly uses points as a page dimension unit in most of the world? Is that an American thing Adobe?!

2021 and still annoyingly lacking A family preset sizes

Yes please, A1-A7, thanks! @adobe

Can we please have the ability to add our own presets in categories we select? Thanks...

It would be so nice to be able to create blanc templates (not only A5 but every custom format) an put it in the wanted section like «print» | «web» | «mobile» etc…
Like this.

While Adobe does not add new templates I use the following workaround:
Create a new document with desired dimensions (once) -> Save as template -> somwhere_you_like/(MY_TEMPLATE.ait) -> move this file to /Applications/Adobe Illustrator XX/Cool Extras/en_GB <or your_language>/Templates/Blank Templates/ (requires password).
Then Illustrator -> New File From Template (shift-command-N) and voilà.

sigghhhhhh... looks like Adobe still hasn't bothered fixing this issue then, even with the latest update I've just done. Its such a basic essential option too!

Adobe, it is 21st century. World is much bigger then US.

agreed!! please sort it out @Adobe!

I can't believe A1-A6 aren't available as presets. Also not clear how to add them myself!

Must agree with poster from March 28, 2019 Muppets.

Sorry for the less than constructive comment but...
Muppets.

Get this stuff fixed.

Just stumbled across this (additional) missing part of AI. Doesn't look like a deliberate decision by Adobe, just another oversight. Please rectify asap.

please

Completely agree! Please add in default new document sizes for all 'A' paper dimensions - A0-A6.

As mentioned elsewhere, I can't believe no one at Adobe has thought to add this in. It must be such a simple thing to do.

Yeah, I work at a printing shop and it sucks that Illustrator doesn't have these size options, making me have to enter it in everytime.

I've found a way to create profiles though which is pretty good.

Go into Illustrator, create the size that you want to save, and then save or place it into:
Mac Computers: Application > Adobe Illustrator > right click Adobe Illustrator app > Select Show Package contents > Required > New Document Profile > en_US > and then drag your new saved Ai file into here.

The new(ish) file new in illustrator has a lovely overview of theses presets, but thinks like the missing A5 AND the lack of any sensible way to save your own presets (see: any other Adobe app) makes me wonder what the point is of this entire window.

Would love to know how to save document presents in the new 'Saved' tab.

Crazy that you can not easily set up A0, A1, A2, A5, A6 etc etc document presets.

Appears that the 'Saved' tab could be for that, but still do not know how to do it!
