Creating Accurate Ruler Guides in Illustrator
Contributed by Neeraj Nandkeolyar, Illustrator Workflow Team
Haven’t we all tried to create ruler guides as accurately as possible, but after zooming in we found the guides were off? This is one of the reasons why most of us drag ruler guides out at maximum zoom. Here are some quick ways to get accurate ruler guides, without having to work zoomed in.
Choose the desired ruler units, either from Preferences, or control-click (on Mac) or right-click (on Win) on the rulers.
First, the basics: to create simple vertical or horizontal ruler guides, drag from one of the rulers into your image. A guide appears where your release your mouse.Now, while dragging the new guide, press the Shift key. This makes the guide snap to visible, accurate sub-divisions on the ruler.This snapping works only for new guides and not for existing ones. So how can you accurately re-position a guide later? First, select the guide, and from the Transform panel or Control panel, change its location on the x-axis (for vertical guides) or y-axis (for horizontal guides).And finally, how can you create vertical guides from horizontal rulers? No problem, just just press Opt/Alt while dragging the guide from the ruler. And accurate snapping with Shift works here as well.
