• Start by selecting ‘New File’ from the Figma dashboard.
• Define the exact dimensions of the canvas according to your project requirements. To ensure pixel-perfect work, input the dimensions explicitly (e.g., 1920x1080).

• Enable grid by clicking on the ‘Layout Grid’ option in the right-hand panel.
• Customize the grid by clicking on the grid settings icon. Set the grid type as ‘Grid’ for square blocks or ‘Column/Row’ depending on the design needs.
• Adjust the grid size for precision. Common grid sizes are 8px or 10px for web design.

• Select the frame or object you are working on.
• Enable 'Pixel Grid' by clicking on the view options in the top-right corner (Shift + P).
• Make sure to align objects to the pixel grid by navigating to the 'Design' tab, and activating ‘Snap to Pixel Grid’. This ensures all elements align perfectly.

• Always manually enter dimensions and positioning values in the sidebar instead of dragging for precision.
• Check and manually adjust 'X', 'Y', 'W', and 'H' values to be whole numbers to avoid fractional pixels.
• Look out for decimal points in the size and position values; they should be avoided for pixel-perfect accuracy.

• Enable pixel preview by clicking on ‘Pixel Preview’ in the view menu or by using the shortcut (Ctrl + ' on Windows or Command + ' on Mac).
• Regularly switch to Pixel Preview when designing to check how your design looks in actual pixels. This is useful especially for icons and small UI elements.

• When designing shapes and vectors, ensure they snap to pixel grid.
• Avoid using fractions in the width and height for vectors.
• Adjust the stroke settings so they align perfectly on pixel grids. This can often mean setting the stroke to inside or outside rather than center-aligned.

• Use images that are 2x or 3x the display size to avoid blurry outcomes.
• Always input precise dimensions for images.
• Be cautious of image compression and quality settings when exporting.

• When exporting assets, select the desired formats (e.g., PNG, SVG) and ensure ‘1x’ and ‘2x’ sizes are included.
• Verify that you are exporting at the correct resolution and that all design elements remain crisp and clear at varying sizes.
• Take the time to review exported assets to confirm they are pixel-perfect and refined.

• Frequently zoom in and out to check the consistency at both macro and micro levels.
• Make adjustments as necessary to maintain quality and sharpness across various scales.
• Continuously inspect the design, especially edges and corners, to ensure all elements are aligned perfectly.

• Utilize design systems or style guides to maintain uniformity in measurements, padding, spacing, and component sizes.
• Adopting symbols/components ensures reusable assets that are inherently pixel-perfect.
• Regularly update and align your design system components to the pixel grid.

Remember, achieving pixel-perfect designs in Figma demands meticulous attention to detail at every step.
