Setting page size in Numbers on Ipad?

I don't see a setting for page size. Everything else related to that (sans setting the page size) appears to be found here:

1. Click the wrench
2. Share & Print
3. Print
4. Select portrait/landscape, content size, page numbering, headers
5. Done (don't actually print it)

I wonder if you set the page size when you actually go to print it. I don't have a printer to try it on. Otherwise it looks like 8.5x11 is all you get.

On my iPad it looks like 8.5x11. But I, too, don't see a way to change it.

One thing you might try is creating a document in Numbers on your computer then transferring it to your iPad. It is supposed to retain the page size settings. You can use this document as a "template" for new documents. I've not tested this, though.
