Rulers provide positioning references, Guides implement element alignment, and Grids builds a systematic layout. 1. Rulers display position coordinates, and can drag out reference lines to check element deviations and judge distance specifications; 2. Guides are virtual lines dragged out from rulers, accurately align elements and divide areas, and support locking and color settings; 3. Grids consist of rows and columns to control the overall layout rhythm, and adapt to responsive design, which are common, such as 12-column web page grids and 8px mobile grids. The combination of the three improves layout efficiency and professionalism.
In design or layout related work, guides, grids, and rulers are the three basic tools for achieving accurate layout. Their core role is to help you align elements, control spacing, and maintain consistency, thereby improving overall visual effects and user experience.
1. Rulers: The basis of positioning
Rulers usually appear on the upper and lower and left edges of the design software interface to display the position of pixels or units. It is the starting point for all precise positioning operations.
- effect :
- Provide coordinate references to let you know the location of each element.
- You can drag and drop out guides and use them as auxiliary lines.
- Practical Tips :
- If you find that the text is not aligned when typing, you can open the ruler to see if the element position is biased.
- In web page or APP design, rulers can help you determine whether the distance between a button from the edge of the screen complies with the specification.
2. Guides: Flexible auxiliary lines
A reference line is a virtual line you drag from the ruler and can be placed anywhere on the canvas to align or divide areas.
- Why use it?
- Helps you accurately align elements such as text, pictures, buttons, etc.
- You can set different blocks such as margins, title areas, and content areas.
- Common usage :
- Drag out four reference lines to set the page's safe margins.
- When aligning multiple objects, the reference lines are much more accurate than the naked eye to judge.
- When multiple people collaborate, unified reference lines help to unify styles.
Tips: Most design software supports "locking the reference line" to prevent mismoving; it can also set the color of the reference line for easy identification.
3. Grids: A powerful tool for systematic layout
The grid is a set of horizontal and vertical lines, forming small grids, like a "skeleton" of design. It is more suitable for design tasks with complex structures, such as web pages, APP interfaces or magazine typesetting.
- Key role :
- Implement modular layout to make the elements arranged neatly and orderly.
- Control column width, row height, margin, etc. to ensure the consistent visual rhythm.
- Supports responsive design and adapts to different screen sizes.
- How to use it to be effective?
- When designing web pages, you can use 12-column grids to flexibly deal with different content combinations.
- The mobile interface often uses 8px or 4px grid systems to facilitate correspondence with margin/padding in the code.
- Beginners can start their practice with a simple 2-column or 3-column grid.
For example: If you are doing a card-style layout, using a grid can ensure that each card is consistent in size, uniform in spacing, and looks more professional.
Let's summarize
- The ruler tells you "what is this"
- The reference line helps you "align this"
- Grids allow you to "coordinate overall"
Use these three together can greatly reduce the time for manual adjustment and avoid problems such as loose layout and misalignment. Many details in the design look inconspicuous, but it is these tools that make the work appear professional and tidy.
Basically all that is, not difficult but very practical.
