Photoshop Guide

Guides are transparent lines that can be placed on the editing canvas as visual markers.
They do not appear in the final print, so they can also be used to indicate trimming or layout instructions.

• Guide lines: Guides can be placed vertically or horizontally and used to align objects or text, or to divide an image into evenly spaced sections.
• Not displayed in output: Guides are for workspace use only. They will not appear in the final saved file or printed output.

To use guides, it is common to start by showing the rulers.

Displaying the Rulers

1. From the menu bar, select [View] → [Rulers].
   ※ Shortcut keys
   • Ctrl + R (Windows)
   • Command + R (macOS)
2. Drag from the ruler area and release at the position where you want to place a guide.
   
   

Creating Guides by Entering Values

From the menu bar, select [View] → [Guides] → [New Guide].

Example: A6 size (100×148)
Data size: 106×154
Horizontal: 3 mm (top)
Horizontal: 151 mm (bottom)
Vertical: 3 mm (left)
Vertical: 103 mm (right)

Managing Guides

You can lock or delete guides from the「View」menu.

• Move: Select the Move Tool and drag a guide to change its position.
• Delete: Drag the guide back onto the ruler to delete it.
  Alternatively, select [View] → [Guides] → [Clear Guides] to delete all guides.
• Lock: To prevent accidental movement, select [View] → [Guides] → [Lock Guides].
  
  

Recent versions of Photoshop include a feature called「Smart Guides」. When moving or transforming objects, temporary guide lines appear automatically as objects approach the edges or center of other elements, assisting with alignment. This makes it easier to confirm spacing and alignment without manually placing guides.
