Add or change a border around an object
Add a border around a sheet
To add a border, such as a solid or dotted line, around a sheet, you first add a square shape to the sheet, then change the shape’s attributes so it behaves like a border. For example, you change the size of the shape, give it no fill (as opposed to a color fill) so that it doesn’t obscure other objects on the sheet, and so on.
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, swipe left and tap No Fill.
Or, if you want the bordered area to have a background color, tap a fill option. You can make the object more transparent so it doesn’t hide other objects on the sheet.
Tap to go back to the Style tab.
Tap to turn on Border.
To choose a border style, color, and width, use the controls that appear.
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.
To lock the border so it doesn’t get moved accidentally, tap Arrange (at the top of the controls), then tap Lock.
When you’re finished, tap anywhere on the sheet to dismiss the controls.
