Photoshop: New guide to snap pixels whilst being dragged

Question

When mouse is dragged through a ruler to create a new guide, I want this guide to move pixel by pixel so that when I leave it, it will have snapped to a side of a pixel instead of staying in the middle.

How can I achieve this?

Thank you.

Answer 1

You need to be at 500% zoom or higher and then hold Shift+Mouse Button to have your guides snap to the pixel grid.

Otherwise, by default it'll snap to:

• every 2 pixels at greater than 100% zoom
• every 5 pixels at 100% zoom
• every 10 pixels at less than 100% zoom

However, if you set your grid to every pixel, then it should snap to the pixel at 100% zoom or greater, even if Snap to>Grid isn't enabled. At zooms less than 100%, you'll need Snap to>Grid as well as have the grid enabled.

But I usually just use the rectangular marquee to mark out the positions where I want my guides to snap to. This avoids having to zoom in or having to change my grid settings.

You can hold Shift while dragging., at least in Windows.

Answer 3

Have you...

1. turned on snap to guides?
2. select a blank layer, so guides won't snap to anything else in the comp.
3. set your ruler measurement by right clicking on the ruler.
4. hold down shift + move your guide which snaps percisely to the ruler setting.

Also when you select View > New Guide and specify a vertical position does this snap correctly?

Sorry if this is duplicating previous suggestions.
