Custom Paper Sizes In Mac Pages

You can create a custom page size with any width or height you like. The trick is knowing where to do to create these sizes, and then how to adjust other things like margins and headers after changing.

Video Summary

In This Tutorial

How to create a custom paper size of any width or height in the Mac Pages app, where to set it up, and how to adjust margins, headers, and units afterward.

Intro

  • A new Pages document uses the default 8½-by-11-inch U.S. paper size, and while the Document sidebar offers other sizes drawn from the printer driver, none of those options allow creating a custom size.

Creating a Custom Size

  • Custom sizes are created under File, Page Setup by setting Format For to Any Printer, then choosing Manage Custom Sizes, clicking the Plus button, naming the size, and entering a width and height such as 5 by 6 inches, keeping the smaller number as the width since orientation can be changed later.
  • Margins can be set here but are easily changed after the document is created, and choosing Any Printer rather than a specific printer is important so the size can be reused, since a printer only offers sizes it supports.

Adjusting the Document

  • After selecting the custom size, the orientation can be switched between Portrait and Landscape, and using View, Show Layout and Show Ruler reveals that the default 1-inch margins leave little space on a small page, so reducing margins and header and footer to about a quarter inch gives a more reasonable body text area.

Printing and Exporting to PDF

  • Printing via File, Print shows a preview, and choosing PDF, Open in Preview confirms the document is the custom 5-by-6-inch size, which is useful because documents are often exported to PDF rather than printed, making unusual sizes practical even when no such physical paper exists.

Reusing the Size

  • The custom size can be reused in new documents (again selecting Any Printer) and saved as a template in the Template Chooser, and because custom sizes are system-wide they appear in other apps like TextEdit via File, Page Setup, allowing consistent sizing when merging PDFs from multiple apps.
  • Sizes can be edited later under Manage Custom Sizes, where they can be removed with the minus button, duplicated and modified, or renamed by clicking the name.

Changing Measurement Units

  • Setting ruler units to centimeters in Pages Preferences only changes the ruler, not the custom size dialog, which stays in inches; switching that dialog to metric requires changing the measurement units under System Preferences, Language & Region, Advanced, a system-wide change, so for a single document it is often simpler to convert the math and stay in one unit.

Summary

Custom paper sizes in Pages are created through File, Page Setup and Manage Custom Sizes using the Any Printer format so they can be reused and applied system-wide, with margins, headers, and orientation adjusted afterward, making them especially handy for producing consistently sized PDFs across multiple apps.

So in Pages when you create a new document it's going to use the default page size. So here if I go to the Document Sidebar and I look at Page Orientation it tells me it's 
8½ by 11 inches. Which is standard paper size in the United States. Now I can change the page size by clicking here and it gives me a variety of different paper sizes. These actually come from my printer driver. So if I switch to say Any Printer Here the list is going to be a little bit different. But regardless of which printer you've chosen you can't create a custom size here. So how do you do it? 
Well, you go to File and then Page Setup. In Page Setup you have a similar set of choices. Let's switch to Format For: Any Printer here. Paper Size we have at the bottom of the list, Manage Custom Sizes. Let's choose that. I'm going to click the Plus button at the bottom here and I'm going to Name it. So let's name this Special and let's do a 
5 x 6 size. Now I'm going to change the width and height here to 5 x 6. I could say 6 by 5 if that's what I want but I'm going to stick with the smaller number being the width knowing I can easily change the orientation later on. Now I've got the Margins here as well. I'm not going to worry too much about those because I can easily change the margins once I've created the document. But let's set these all to a ¼ inch. Then I'm going to click OK. 
So now when I look at paper size I'll see this as a selection here. Note it's a little bit different if I were to choose a specific printer. I'd see this size there but I can't choose it because the printer doesn't have that size in its settings. So choosing Format for any printer is very important if you want to reuse the size from the list. At this point I can use Portrait or Landscape and actually switch the orientation. I'm just going to use Portrait right here and now I can see in the Document Sidebar I've got 5 by 6. Page orientation is Portrait. I can switch it to Landscape. So you can see how easily I got 
6 by 5 there. Then I've got other information here like Margins. Margins aren't great now because I've got 1 inch margins all around but it is a small paper size. Let's go to View and then Show Layout and then on top of that View, Show Ruler so we can see what's going on here. You can see with the 1 inch margins there is not much space here. I probably want to go and set it to something else like let's do ¼ inch margins all around and let's change the Header to only be a ¼ inch and the same for the Footer, like that. So that's a more reasonable size for the body text when I'm using such a small page size. 
So now let's fill this with some sample text. Now let's try printing. I'm going to go to File Print and when I do I could see the Preview here. I could also go to PDF and Save it as a PDF or more conveniently for us in this tutorial Open in Preview. So it just creates a PDF and goes right to Preview. So I can see what's going on here. Click the Information button at the top and I could see that it is, indeed, a 5 by 6 inch PDF here. Often today we're creating word processing documents and exporting them to PDF's not really printing on physical paper. So doing unusual sizes like this can make sense a lot of times even if that paper size doesn't really exist. 
Now if I want to reuse this size I can go create a new document and then under Document here I can select it. But remember I need to select Any Printer there. If I leave it at my printer it is just going to have the sizes supported by that printer. So now I can select that 5 by 6 and easily reuse that page size all the time. As a matter of fact I can take this document right now and I could save it as a template. So I'll add it to the Template Chooser. It's right here. I can give it a name. But if I create a new one you could see how this document is created using that special page size. Better still the page sizes are system-wide. So here I am in a completely different app. TextEdit. If I go to File, Page Setup I can choose that page size right there. TextEdit doesn't show those page sizes here. It allows you to do what you want. But when I go to Print you could see it's using that page size. 
So if you have to produce a document where some of it comes Pages and others come from other apps you can use that same page size when exporting to PDF for all of them and that way you can merge them later on and everything is a consistent size. You can always go back in File and then Page Setup and then edit these sizes under the same Manage Custom Sizes dialogue here. You can select one. There's a minus button to remove it. You can even Duplicate one and then change, slightly, some of the parameters. You can always click on the name here and then rename it as well. 
Note that in Pages Preferences, under Rulers, you can set the ruler units to centimeters and then you're going to have to start a new document in order for those changes to take effect. So let's create a new document right here. Notice under Document I've got now centimeters for Page Orientation. Then I go to Manage Custom Sizes it is still going to be in inches. To actually get it to do centimeters there I need to go into System Preferences and then go to Language & Region and then go to Advanced and under there there is measurement units. If I change that to Metric now when I go in Pages to File, Page Setup then I'm going to see centimeters, or millimeters in this case, for the units. The change would be system-wide. So if you just want to do it in Pages but keep everything else in inches, it's best probably to do the conversion math and stick to inches here, or vice versa if you want to use inches here but stick with metric elsewhere. 
So I hope you found this useful. Thanks for watching.

    In the past I have set up a page-size that was A4 in width (210 mm) but ridiculously long (several metres) in order to produce a scrollable PDF file with no page breaks.
