Planning Your Icon System

Before editing, plan your system. Define scope: core UI icons? Branding elements? Number needed: start with 20–50 essentials.

Choose style: outline (minimal), filled (bold), duotone (trendy). Consider brand: modern sans-serif? Traditional serif?

Establish guidelines: stroke width (1.5–2px), corner radius, grid size (24x24px), visual weight balance.

List categories: navigation, actions, status, social, etc. Prioritize based on project needs.

Plan for variants: light/dark mode, hover states, disabled versions.

Document in style guide for team consistency.
