Stroke width

All icons are designed with SVG elements using strokes. These have a default stroke width of 2px.

The strokeWidth can be adjusted to create a different look of the icons.

Adjusting stroke width with the strokeWidth input

import { Component, ViewEncapsulation } from "@angular/core";
import { LucideFolderLock } from "@lucide/angular";

@Component({
  selector: 'app',
  imports: [LucideFolderLock],
  template: `<svg lucideFolderLock [strokeWidth]="1" />`,
  styleUrls: ['./app.component.css'],
  encapsulation: ViewEncapsulation.None,
})
export class App {
}

Absolute stroke width

When binding the size input, the icon's stroke width will be relative to its size, this is the default SVG behavior. The absoluteStrokeWidth input is introduced to adjust this behavior to make the stroke width constant no matter the size of the icon.

This means that when absoluteStrokeWidth is enabled and the size of the icons is set to 48px the strokeWidth will still be 2px on the screen.

Note 2px is the default stroke width for a Lucide icon, this can be adjusted to all sizes.

Absolute stroke width comparison

Adjusting stroke width with absoluteStrokeWidth input

Setting absoluteStrokeWidth to true will make the stroke width absolute.

import { Component, ViewEncapsulation } from "@angular/core";
import { LucideRollerCoaster } from "@lucide/angular";

@Component({
  selector: 'app',
  imports: [LucideRollerCoaster],
  template: `
  <svg
      lucideRollerCoaster
      [size]="96"
      [absoluteStrokeWidth]="true"
    ></svg>
`,
  styleUrls: ['./app.component.css'],
  encapsulation: ViewEncapsulation.None,
})
export class App {
}
