Set guide and grid preferences
1 Do one of the following:
• (Windows) Choose Edit > Preferences > Guides, Grid, Slices & Count.
• (Mac OS) Choose Photoshop > Preferences > Guides, Grid, Slices & Count.
2 For Color, choose a color for the guides, the grid, or both. If you choose Custom, click the color box, choose a
color, and click OK.
3 For Style, choose a display option for guides or the grid, or both.
4 For Gridline Every, enter a value for the grid spacing. For Subdivisions, enter a value by which to subdivide the
grid.
If desired, change the units for this option. The Percent option creates a grid that divides the image into even
sections. For example, choosing 25 for the Percent option creates an evenly divided 4-by-4 grid.
5 Click OK.
Use snapping
Snapping helps with precise placement of selection edges, cropping marquees, slices, shapes, and paths. However,
sometimes snapping prevents you from correctly placing elements. You can enable or disable snapping using the
Snap command. You can also specify different elements to which you want to snap when snapping is enabled.
Enable snapping
❖ Choose View > Snap. A check mark indicates that snapping is enabled.
Specify what to snap to
❖ Choose View > Snap To, and choose one or more options from the submenu:
Guides Snaps to guides.
Grid Snaps to the grid. You cannot select this option when the grid is hidden.
Layer Snaps to the content in the layer.
Slices Snaps to slice boundaries. You cannot select this option when slices are hidden.
Document Bounds Snaps to the edges of the document.
All Selects all Snap To options.
None Deselects all Snap To options.
A check mark indicates that the option is selected and snapping is enabled.
If you want to enable snapping for only one option, make sure the Snap command is disabled, and then choose
View > Snap To and choose an option. This automatically enables snapping for the selected option, and deselects all
other Snap To options.
Show or hide Extras
Guides, grid, target paths, selection edges, slices, image maps, text bounds, text baselines, text selections, and annota-
tions are nonprinting Extras that help you select, move, or edit images and objects. You can turn on or off an Extra
or any combination of Extras without affecting the image. You can also show or hide Extras by choosing the Extras
command in the View menu.
