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.
