If you want to make composite images, add text to a picture, or just tweak some individual elements of a photo in Photoshop, you need to know how to change the size of a layer in Photoshop. Layers are at the heart of so many of Photoshop's best features, so it's something any photo editor should know how to do.

Fortunately, learning the process is pretty quick and there are even a few different ways you can do it.

The following guide focuses on Adobe Photoshop CC version 20.0.4. Most methods will also work with older versions of Photoshop, but the methodology may not be as exact.

How to Change the Size of a Layer in Photoshop

There are a couple of different ways you can change the layer size in Photoshop, and both involve the Transform tool. There are options for freely adjusting the size up or down, and inputting specific measurements to get it exactly to the size you want. Here's how to do it.

If you don't see the Tools menu, select Window > Tools.

Free Transform

  1. Select the layer that you want to adjust the size of in the Layers window.

    If you don't see it, select Window > Layers, or press F7.

  2. Press Ctrl (or CMD)+T to open the Free Transform options.

  3. Select any of the sides of the layer, or the bounding boxes, and drag them in the direction you wish to adjust the layer's size. Drag away from the center to increase its size, or drag towards it to reduce it.

    Press and hold Shift to maintain aspect ratio. You can also rotate the layer by selecting and holding anywhere outside of the layer's bounding box and dragging it clockwise or counter-clockwise.

  4. When you're happy with the new size, press Enter or double-click/tap to finalize it.

Other Transform Tools

There are a number of other transform tools you can use, although they reshape the layer as much as they resize it. If you don't want a linear increase in size for your layer, want to alter its perspective, or change its proportions, select Edit > Transform, then select one of the tools listed there (other than Free Transform). They all do quite different things, so play around with them to see what kind of effects you can conjure.

If at any time you don't like the results of your resizing, press Ctrl (or CMD)+Z to undo your action. Alternatively press Ctrl (or CMD)+Alt+Z to take several undo steps.

Transform to a Specific Dimension

If you don't want to freehand transform your layers, but have some specific dimensions in mind, you can set its size to exactly that.

  1. Select the Move tool (top of the Tools menu list), then select Show Transform Controls.

  2. Select the bounds around your chosen layer and look back up to the top menu bar. There you'll find X, Y, and H dimensions. You can alter them based on percentage or pixel number. Adjust them as you see fit, to the size you want your layer to be.

  3. When you're happy with the results, press Enter or select the checkmark on the right-hand side of the menu bar.

If you don't want to maintain the same aspect ratio, select the chain-link icon to remove the restriction.
