Let’s walk through a step-by-step practical tutorial on designing an icon. I’ll show you how to design a simple “search” (magnifying glass) icon in Adobe Illustrator. You can also follow the same logic in Figma or Sketch.
Step-by-Step Tutorial: Designing a Search Icon
Step 1: Set Up Your Artboard
Open Adobe Illustrator.
Create a new document (File → New).
Size: 500px x 500px (large enough to work with).
Color Mode: RGB (for digital).
Units: Pixels.
Step 2: Create a Grid System
Go to View → Show Grid.
Enable Snap to Grid (View → Snap to Grid).
This ensures shapes align perfectly.
Set grid spacing:
Preferences → Guides & Grid → Gridline every 10px, Subdivisions: 2.
This gives you a clean pixel grid.
Step 3: Draw the Lens (Circle)
Select the Ellipse Tool (L).
Hold Shift while dragging to create a perfect circle.
Size: 160px x 160px.
Stroke: 8px (black).
Fill: None.
Center it on your artboard.
Step 4: Draw the Handle
Use the Rectangle Tool (M) to draw a thin rectangle.
Size: 60px long x 12px wide.
Stroke: 8px (same as circle).
Fill: None.
Rotate it 45° (Object → Transform → Rotate).
Place one end so it touches the bottom-right edge of the circle.
Step 5: Adjust for Balance
Check alignment: the handle should connect naturally to the circle.
If needed, expand strokes (Object → Expand → Stroke) and use the Pathfinder → Unite to merge them into one shape.
Step 6: Test at Small Sizes
Copy your icon and scale it down to 24px x 24px and 16px x 16px.
Zoom in to see if it’s still recognizable.
If the handle looks too thin, increase stroke weight slightly.
Step 7: Export the Icon
Go to File → Export → Export As.
Choose formats:
SVG (best for web, scalable).
PNG (for app interfaces, 1x, 2x, 3x sizes).
ICO (if needed for software).
Save multiple sizes: 16px, 24px, 48px, 64px, 128px.
Step 8: Create a Consistent Style (Optional)
If you’re building a set of icons:
Always use the same stroke weight (e.g., 2px at 24px size).
Keep corners rounded or sharp consistently.
Use the same grid system.
