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.
