Resizing multiple layers in Photoshop simultaneously is straightforward. Here's how:
Linking Layers for Simultaneous Resizing
The most efficient method involves linking the layers you wish to resize. This ensures that all selected layers resize proportionally when you use the Free Transform tool.
-
Select Layers: In the Layers panel, click the first layer you want to resize. Then, hold down the Shift key while clicking each subsequent layer you want to include. This selects multiple, non-contiguous layers. Alternatively, hold down the Ctrl (Windows) or Command (macOS) key to select multiple, non-contiguous layers.
-
Link Layers: Once all desired layers are selected, look for a chain-link icon at the top of the Layers panel. Click this icon to link the selected layers. This ensures that they move and resize as a single unit. Note that you can unlink them later using the same icon.
-
Free Transform: Press Ctrl+T (Windows) or Cmd+T (macOS) to activate the Free Transform tool. A bounding box will appear around the linked layers.
-
Resize: Hold the Shift key to maintain the aspect ratio. Then, click and drag one of the corner handles of the bounding box to resize all linked layers proportionally.
Resizing All Layers Individually (To a Specific Size)
If you need to resize all layers to a specific dimension, linking might not be the most efficient method. You could utilize Actions for this. However, here's a process utilizing the Free Transform tool and a small degree of manual intervention:
- Select All Layers: Select all layers in the Layers panel (Ctrl+A or Cmd+A).
- Free Transform: Use Ctrl+T (Windows) or Cmd+T (macOS).
- Resize: Enter the exact pixel dimensions into the width and height fields that appear in the Options Bar. This method resizes all selected layers to the same specific dimensions.
Important Considerations
- Aspect Ratio: Holding the Shift key while resizing with Free Transform maintains the original aspect ratio of all layers. Without it, layers are resized disproportionately.
- Layer Order: The topmost layer is usually displayed over the other layers. After resizing, layers can overlap unexpectedly. It is a good practice to arrange layers as desired after the resize process is complete.
This comprehensive approach addresses various scenarios involved in resizing multiple layers in Photoshop. Remember to always back up your work before applying extensive edits.
