How do you create flat icons?

Creating flat icons: understand flat design, choose topic, sketch, use vector editor, basic shapes, limited colors.

You create flat icons by following the step-by-step guide below.

Understand the principles of flat design: Familiarize yourself with the core characteristics of flat icons. This includes:
- Minimalism: Focus on essential elements and avoid unnecessary details.
- Two-dimensionality: No gradients, shadows, or bevels to create depth.
- Geometric shapes: Often relies on basic shapes like circles, squares, and rectangles.
- Clean lines: Sharp and well-defined edges.
- Limited color palette: Typically uses a concise and often vibrant set of colors.
Choose your icon topic: Decide what your icon will represent. This could be anything from a file type to a social media platform.
Sketch your idea (optional but recommended): Before jumping into a digital tool, sketch out a few rough ideas on paper. This helps you visualize the concept and explore different compositions quickly.
Select a vector graphics editor: Flat icons are best created using vector graphics software like Adobe Illustrator, Sketch, Figma, or Inkscape (which is free). Vector graphics are scalable without losing quality, making them ideal for icons.
Set up your artboard: Create a new document in your chosen software. A common size for icons is 64×64 pixels or 128×128 pixels, but you can adjust this based on your needs. Ensure your artboard is set to a pixel grid for crisp edges.
Start with basic shapes: Begin building your icon using fundamental geometric shapes. For example, a speech bubble might start with a circle and a triangle.
Simplify and remove unnecessary details: This is crucial for flat design. Eliminate any decorative elements, textures, or complex details. Focus on the core visual representation of your topic.
Choose a limited color palette: Select a small set of colors that complement each other. You can use online color palette generators or draw inspiration from existing flat design styles.
Apply color: Fill your shapes with the chosen colors. Remember, flat design typically uses solid, uniform colors without gradients.
Consider stroke (optional): You can add a simple, consistent stroke (outline) to your icon if desired. Keep the stroke weight thin and the color consistent throughout your icon set.
Refine and adjust: Take a step back and review your icon. Make any necessary adjustments to the shapes, colors, and overall composition to ensure it’s clear, recognizable, and visually appealing.
Export your icon: Once you’re satisfied, export your icon in appropriate formats. Common formats for web use include SVG (Scalable Vector Graphics) and PNG (Portable Network Graphics). For SVG, ensure it’s optimized for web use. For PNG, export at the desired resolution (e.g., 64×64, 128×128).
