Use alignment guides

When moving and sizing layers, smart spacing and sizing guides automatically appear to help you precisely place and resize layers. They are invisible most of the time and only appear if you move or resize a layer in your image and it becomes a similar size or equidistant to another layer. You can also add persistent alignment guides that are always visible in your image. Certain guides are turned on by default and other, additional guides can be turned on or off in Pixelmator Pro settings.

Turn on Smart Guides

Smart Guides appear when a layer or a layer group matches the size or position or another layer or layer group. Smart Guides can also help equally space three or more objects in a line.

  1. Do one of the following:
    • Choose Pixelmator Pro > Settings (from the Pixelmator Pro menu at the top of your screen), then click the Rulers tab.
    • Choose View > Smart Guides (from the View menu at the top of your screen.
  2. Select any of the options:
    • Show guides at object center: Guides appear when the center of an object aligns with the center of another object or the center of the image.
    • Show guides at object edges: Guides appear when the edges of an object align with the edge of another object or the edge of the image.
    • Show guides for relative sizing: Guides appear when an object matches the size of another object.
    • Show guides for relative spacing: Guides appear when three or more objects are placed equally apart in a line.

Tip: If you want, you can change the color of the Smart Guides in Pixelmator Pro settings.

Add persistent alignment guides

You can add alignment guides that remain visible on your image while you’re working, even if you close the image and return to it later. You can add as many guides as you like and position them to suit your needs. Alignment guides are unique to each image you edit.

  • Control ⌃ – click the vertical or horizontal ruler, and choose Add Guide.
  • Double-click a ruler, choose the orientation and position of the ruler and click OK to add the guide.
