About this icon

Use the Window Header Horizontal 20 Regular icon

This outline icon from Fluent UI Icons works well across weather forecast apps, climate dashboards, location-based services, environmental widgets, and IoT sensor displays. The outline visual style is specifically suited for app navigation bars, toolbar buttons, form labels, and UI controls where clarity at 16–24px is critical.

Customize it in IconStash: pick a color preset or enter any hex code, set exact dimensions, adjust stroke weight, then copy SVG code or download a PNG — no account needed.

Export formats

Copy clean SVG vectors with one click, generate custom-size PNG files from 16px to 512px, export JSX/React components ready to paste into your project, or use the icon as a CSS background-mask for flexible theming.

All exports are based on the same editable vector — so the Window Header Horizontal 20 Regular icon stays pixel-perfect at 16px, 24px, 48px, and any large marketing size.

Design & UX integration

Aesthetic characteristics

Fluent UI Icons is Microsoft's set, and Window Header Horizontal 20 Regular follows its sizing system — the same glyph is redrawn at 12, 16, 20, 24, 28, 32 and 48px rather than simply scaled, so the stroke weight stays perceptually constant as size changes. Each icon also ships as Regular and Filled.

UX best practices

Weather icons are scanned rather than read, so the Window Header Horizontal 20 Regular icon must stay legible at small sizes and be consistent with the rest of the forecast set. The most common mistake is mixing outline and filled glyphs across one forecast row, which makes a single strip look like two different data sources.

Use in your project

React / npm — Fluent UI Icons

npm install @fluentui/react-icons

import { WindowHeaderHorizontal20RegularRegular } from '@fluentui/react-icons';

// JSX usage:
<WindowHeaderHorizontal20RegularRegular fontSize={24} />

Copy the SVG markup directly from the IconStash editor to use the Window Header Horizontal 20 Regular icon without any npm package — paste it into HTML, JSX, or a design tool.
