Changing the grid size in Kicad's Schematic Editor is straightforward and essential for precise component placement and wiring. The grid defines the points your cursor snaps to, ensuring connections align correctly.
Understanding the Schematic Grid
In the Kicad Schematic Editor, elements like symbols and wires snap to an underlying grid. This snapping behavior helps maintain neatness and ensures electrical connections are properly formed. You can customize the size of this grid to suit different tasks, such as placing components on a coarse grid and then routing fine wires on a smaller grid.
Methods to Change the Grid Size
According to the Kicad documentation, you have two primary methods to adjust the grid size in the Schematic Editor:
-
Using the Right-Click Menu:
- Right-click anywhere on the schematic sheet background.
- A context menu will appear.
- Look for a "Grid" or "Grid Properties" option.
- Select the desired grid size from the available options or access a properties dialog to enter a custom value.
-
Using the View Menu:
- Navigate to the menu bar at the top of the Kicad window.
- Click on the View menu.
- Select the Grid Properties... option from the dropdown menu.
- This will open a dialog box where you can specify the grid size, often in units like inches (mils) or millimeters.

| View Menu | View -> Grid Properties... |
Practical Considerations
- Standard Grid Sizes: Kicad typically offers standard grid sizes (e.g., 50 mil, 100 mil). Using these standard sizes is often recommended, especially 100 mil, as many standard library symbols are designed to connect properly on this grid.
- Fine Grids: You might switch to a smaller grid size (e.g., 10 mil, 5 mil, 1 mil) when you need to make fine adjustments or route wires in crowded areas.
- Visual Aid: The grid itself can be made visible or hidden via the View menu or display options to serve as a visual guide while you work.
By utilizing these methods, you can effectively manage the cursor snapping behavior in the Schematic Editor, leading to a more organized and electrically sound design. Remember that the grid setting specifically affects cursor movement and snapping for placement and routing.
