The "New Guide" is super-handy as well! It wouldn't necessarily work for the cases where you're attempting to align guides after-the-fact to already created elements, but it would be fantastic as a first step, for laying down guides for a grid-based layout.

I love that you can give it values in any measurement that Photoshop understands, even percents of canvas size.

Still, I use marquee selections constantly for positioning within elements and for determining widths/distances and whatnot. The marquee would have to be the tool that is most often active in my Photoshop toolbar.

For example, I'll use a marquee to get my padding in a content box, by putting guides around the box, drawing out a square marquee to the size I want for padding, moving it to three corners, and placing guides for the interior content area of my container element as I go.

Thanks for the tip! The shift-key certainly would be a simpler method than what I've outlined above. However, as a commenter pointed out on another post, using the shift-key is dependent on your ruler units setting, and on your zoom level.

Honestly, I haven't tested this yet (or at least not recently enough for me to remember the results…), so I can't say for sure, but it seems that the way I outline above may still be the most foolproof method.

Thanks for the tips!

There is a better way ! Hold down the Shift-key while dragging the guide. It will be a pixel-precise guide !

Well done. I’ll be sending this to some of our folks.
