How Do I Change the Resize in Photoshop?

Resizing images in Photoshop is straightforward and can be accomplished in several ways, depending on whether you want to resize the entire image or just individual layers.

Resizing the Entire Image

To resize your entire Photoshop document:

1. Open the image: Start by opening your image in Photoshop.
2. Access Image Size: Go to Image > Image Size. This opens a dialog box with options to change the dimensions (width and height) and resolution (pixels per inch or ppi).
3. Adjust Dimensions: Enter your desired width and height. Check the "Constrain Proportions" box to maintain the aspect ratio; otherwise, your image might become distorted. You can also change the resolution here, but be mindful that increasing resolution doesn't add detail; it only increases file size.
4. Resampling: Choose a resampling method (like Bicubic Smoother or Bicubic Sharper) if you're changing the resolution. The method you select will affect image quality after resizing.
5. Apply Changes: Click "OK" to apply the changes.

• Tip: For enlarging images, it's often best to work with a high-resolution original to minimize quality loss. Consider increasing the resolution before enlarging if you're scaling up considerably. Also, increasing resolution does not add detail if the original was low resolution.

Resizing Individual Layers

If you need to resize a specific layer within your Photoshop document:

1. Select the Layer: Select the layer you want to resize in the Layers panel.
2. Free Transform: Go to Edit > Free Transform (or press Ctrl + T on Windows or Cmd + T on Mac). A bounding box appears around the layer.
3. Resize: Drag the corner handles of the bounding box to resize. Hold down the Shift key while dragging to maintain the aspect ratio.
4. Apply Transformation: Press Enter (Windows) or Return (Mac) to apply the changes.

• Tip: You can also use the transform controls to rotate, skew, or distort the layer.

Using the Transform Tool for Quick Resizing

For a quicker method, you can use the Transform tool directly:

1. Select the layer you want to resize.
2. Press Ctrl + T (Windows) or Cmd + T (Mac) to activate the Free Transform tool.
3. Drag any corner of the bounding box while holding down the Shift key to resize proportionally. Releasing the mouse button applies the changes.

The choice of method depends on your needs. Use Image > Image Size for resizing the entire document, and Edit > Free Transform or Ctrl+T/Cmd+T for resizing individual layers within the document. Always consider the aspect ratio and resampling method for optimal results.
