Alright, let's get those rulers up in Figma. Head to the top menu, click on View, then select Rulers. Or, if you're into shortcuts, just hit Shift + R. You'll see rulers pop up at the top and left side of your canvas.

Now, let's add some guides. Click and drag from either the top or left ruler to place guides on your canvas. These are super handy for aligning layers and keeping your spacing consistent.

Time to add a grid. Select the frame or canvas where you want it. Look over to the right sidebar, find the Layout Grid section, and click the + icon. Boom, you've got a grid.

In the Layout Grid settings, you can pick from different grid types like Columns, Rows, or Grid. Tweak the Count, Margin, Gutter, and Type fields to fit your layout needs.

For precise placement, turn on snapping. Go to View, then Snap to Pixel Grid, or use Ctrl + Shift + 4. This makes items snap to the grid and guides as you move them around.

Use those guides and grid to get everything aligned and organized. Move layers and elements so they line up perfectly with your grid lines and guides. Your layout will look neat and cohesive.

Once your guides are set, lock them to avoid accidental changes. Right-click on a guide and select Lock Guides. To unlock, right-click again and choose Unlock Guides.

To clear up your workspace, you can hide the guides and grid temporarily. For guides, go to View and select Hide Guides. For the grid, just uncheck the grid option in the Layout Grid section of the right sidebar.

For even more precise adjustments, select elements and use the arrow keys to nudge them by 1px. Or, use Shift + Arrow keys to nudge by 10px. This lets you fine-tune positioning.

To keep things consistent across projects, save your grid settings. Create a sample frame with the grid you like, then duplicate this frame whenever you start a new project. This way, your designs will always be uniform.

Utilize Figma’s ruler and grid tools to make sure your layouts are precise, aligned, and professional.
