Use alignment guides in Numbers on Mac
Use alignment and spacing guides to help you place objects precisely on a sheet. When guides are turned on, they appear as you drag an object on a sheet in alignment with, or equidistant to, another object. You can turn the guides off and on as needed.
You can also add your own horizontal or vertical alignment guides and place them anywhere on a sheet. These persistent alignment guides don’t appear and disappear as you drag objects, but remain visible while you’re working.
Turn on alignment guides
Choose Numbers > Settings (from the Numbers menu at the top of your screen), then click Rulers at the top of the settings window.
Select any of the options:
Show guides at object centre: Indicate when an object’s centre aligns with another object’s centre or the centre of the sheet.
Show guides at object edge: Indicates when an object’s edges align with another object’s edge or an edge of the sheet.
Show guides for relative sizing: Indicate when an object matches another object’s size in a particular dimension (for example, height).
Show guides for relative spacing: Indicate when three or more objects are placed equally apart in a line.
You can also change the colour of the alignment guides. In Rulers settings, click the colour well next to Alignment Guides, then choose a colour.
Add persistent alignment guides
You can add alignment guides that remain visible on the sheet while you’re working, even if you leave the sheet and return to it later. You can add as many guides as you like and position them to suit your needs. Alignment guides are unique to each sheet.
If you can’t see rulers, click
in the toolbar, then choose Show Rulers.Move the pointer over the vertical or horizontal ruler, then drag to the sheet.
To change the location of an alignment guide, drag it.
Remove, hide or clear persistent alignment guides
Do any of the following:
Remove a horizontal guide: Drag it up and off the sheet.
Remove a vertical guide: Drag it to the left and off the sheet.
Hide all guides: Choose View > Guides > Hide Guides (from the View menu at the top of your screen, not the View button in the toolbar).
To show all guides again, choose View > Guides > Show Guides.
Clear all guides: Choose View > Guides > Clear All Guides on Sheet.
Change the colour of alignment guides
Choose Numbers > Settings (from the Numbers menu at the top of your screen), then click Rulers.
Click the colour well next to Alignment Guides, then choose a colour.
Tip: You can add a button to the toolbar to show and hide guides.
