Photoshop Auxiliary tools. the program itself has always had built-in options that make it easier for users to work in the program. You can find all these options and other aids in the View drop-down menu, while additional options related to them are set in the Preferences window.


Photoshop Auxiliary tools.When creating a new document, you specify the sizes in certain units of measurement, and thus you also specify the units of measurement on the rulers as the basic ones in the document. There are two rulers within each document that measure the width and height of the document, ie the x and y coordinates.

If you want to show rulers, you can do so in the View drop-down menu, by ticking the Rulers command you will show / hide rulers, and you can also achieve the same with the keyboard shortcut Ctrl + R.

Photoshop Auxiliary tools.. When you created a new document in one of the previous lessons, you saw that you can assign a standard unit of measure to each new document, but you can easily change that on the ruler. Right-click on the ruler and a pop-up menu will open in which the active measuring unit will be displayed (ticked), as well as other offered ones that you can choose from.


Guides are guides that will not be visible in the end result (on the web or in print). They are very useful because they help in design, alignment of elements, etc. You can create guides in two ways. If you click on the ruler with the left mouse button and start dragging (holding the left mouse button), you will draw one guide, horizontal or vertical, depending on which ruler you created it from. Another, much better and more accurate way to create guides is with the New Guide command…

The New Guide window will open, in which you can select a horizontal or vertical guide, while specifying its position in the field below. If you are doing something precise, always use this method to create guides.

If you want to move the existing guide, activate the Move tool (V) located at the top of the ToolBox (black arrow). When you move the cursor over the guide, you will notice that it will change according to its orientation, then by clicking and dragging you can move it to a new position. If you want to delete one guide, select it and return it to the ruler. If you want to delete all existing guides that are in the active document, run the Clear Guides command from the View drop-down menu.

Photoshop Auxiliary tools.Since the Move tool is also used to move layers, it often happens that the guides bother you in their selection, which is why it is advisable to lock them with the Lock Guides command.


One of the most important characteristics of guides is the Snap option, ie capturing elements that approach it at a certain vicinity. For guides to have this feature, the Snap option must be checked in the View drop-down menu. Each time you bring a new object closer to the edge of one of the guides, Photoshop will stick it to them as if they were magnets. Even if you create a guide and want to stick it to the edge of an existing layer, this will happen when you get close to it.

In addition to guides, the snap option can be assigned to other things in Photoshop. To determine what some objects or guides will be glued to, open the Snap To submenu and check the desired items.

  1. Guides
  2. Document Auxiliary Network
  3. The edges of the layers
  4. Clips
  5. Document edges

Smart Guides

Smart Guides are not classic guides that you can draw from a ruler, they are very useful aids that warn you when something is aligned (Aligned). You cannot see the Smart Guide on the desktop until you select a specific item in the work and start dragging it. Then smart guides appear when the edges of that element align with the edges of another or the center.

Also, when Smart Guides notices a certain alignment with another element, then the Snap To option happens. The more useful and good it is in layout design, the more it can sometimes bother you, then you can turn it on / off by running the View> Show> Smart Guides command.


When designing a variety of content, both for print and for the web, positioning the elements, and proportions are crucial. To help you manage these items, Photoshop offers you grids. The grid is divided into segments and each of them is sensitive, in the sense that the newly created object or element that you drag will be glued to them.

Gridlines & Subdivisions
  1. Gridlines – lines that form a network
  2. Subdivision – a segment of the network, the lines that mark them are brighter

The dimension of the network and network segments can be adjusted in the Preferences window in the Guides, Grids & Slices section. The keyboard shortcut to hide / show the network is Ctrl +;


If you want to hide / show all the aids to see your work better, you can do so with the View> Extras command or the keyboard shortcut Ctrl + H. So you can have nets and a large number of guides, and with just one stroke you can hide all these accessories to see the work, and show them again to continue with the design..

It is important to note that none of the mentioned aids will be seen in the end result. an exported document intended for printing or the web.


In previous tutorials, you learned that you can adjust the behavior and appearance of the program in the Preferences window. There are two sections in this window that are related to all the aids we mentioned in this lesson.

Units & Rulers

In this section, you can generally specify the standard unit of measure for an active document, but there is another extremely useful item here. In the New Document Preset Resolutions section, there are the Print and Screen Resolution fields. You do not need to change the Print value because it is always the standard 300 ppi, but be sure to change the value in the Screen resolution field (for the active document) when preparing the document for printing, entering the correct resolution of your monitor. Why?

In the View drop-down menu, there is an option to view the document called Print Size. When the value in Screen resolution is equal to the value of your monitor, then the Print Size command will display the active document in a 1: 1 ratio – that is, in the exact size intended for printing. This means that 1cm on the screen in the active document preview will actually be displayed as 1cm.

Look at grids in design as a construction in architecture, it is so important that everything you do in design is in proportions, with certain positions, spacing, etc.

Guides, Grids & Slices

In this section, you can set standard colors for guides, smart guides, and grids. In addition, it is in this section that you are able to determine how far between network lines there will be and how many segments there will be between them.

Note: When you open the Preferences window, all changes will apply to the currently active document, and if you open it when no document is open, all changes will become standard for each newly created or open document.

Recommended keyboard shortcuts:

Ctrl + R – Show / Hide Rulers Ctrl +; – Show / Hide Grids Ctrl + H – Show / Hide Extras
