Add a border around a page in Pages on iPhone
To add a border — such as a solid or dotted line — around a page, you first add a square shape to the page, then change the shape’s attributes so it behaves like a border. For example, you can change the size of the shape, give it no fill (as opposed to a colour fill) so that it doesn’t obscure other objects on the page, set it to always stay on the page, and so on. You can then set the border as a section layout object so it appears on all pages.
Tap
, then tap 
.In the Basic category, tap a square or rounded rectangle to add it.
Drag the blue dots that appear around the shape until the outer edges of the shape form the border size you want.
Tap
, then tap Style.Tap Fill, tap Preset, then swipe left and tap No Fill.
Or if you want the bordered area to have a background colour, tap a fill option. You can make the object more transparent so it doesn’t hide other objects on the page.
Tap
to go back to the Style tab.Tap to turn on Border, then use the controls to choose a border style, colour and width.
To change the transparency, drag the Opacity slider (at the bottom of the controls).
To move the border behind all the objects on the page, tap Arrange, then drag the slider all the way to the left.
If your document is a word processing document, turn off Move with Text, then change Wrap to None.
To lock the border so it doesn’t get moved accidentally, tap Arrange (at the top of the controls), then tap Lock.
When you’ve finished, tap anywhere on the page to dismiss the controls.
