Griddify is similar to the extension GuideGuide, but slightly different acting. The principle, of course, plays the same – install the guide on your request, but system editing and pasting these guides are made differently. Let’s consider it in more detail.

First you have to download this extension via the link provided at the end of this article. Then upload the files (after unpacking the archive, of course) in the plugins folder of Adobe Photoshop.
To launch the menu Window-Extensions, choose Griddify and open it.
Will be a special panel through which you organize the guide of any complexity. Here are a few examples for clarity:
Here are the guides relative to the pixels 10, 20 and 30 form a grid throughout the space of the open document. You can use them for selection, not just entire document.
The second option:
We divided the sheet into 3 parts horizontally, just entering a value and choosing the direction of division. Direction you can choose in all points of this panel is very convenient.
And finally, the third option:
Here we made a small indentation with a size of 50 pixels.
Overall a great solution for designers and web designers, as it can offer huge opportunities for the rapid introduction and guidelines of the organization of meshes for subsequent processing.
