Square Icon Generator

What the square icon means

A checkbox, a stop control, or a neutral container. In media controls a filled square means stop.

Pure geometric shapes are containers rather than symbols: a circle, square, triangle or hexagon means whatever you put inside it or next to it. That makes them the most flexible marks available and the least self-explanatory. As app icons they are extremely robust — a filled shape is the most downscale-resistant thing you can draw — and they work best when the shape itself is doing the differentiating, for example a hexagon in a category where everyone else ships a rounded square.

Where you will actually see it

• checkbox controls
• stop buttons in players and recorders
• app icons using a square container

Drawing the square at 16 pixels

Perfectly robust when aligned to the pixel grid. Off-grid, the edges blur — snap the coordinates to integers.

Stroke weight is the control that matters most here. Lucide icons are drawn on a 24 × 24 grid with a 2px stroke, which means that when the icon is scaled down to 16px the stroke is effectively 1.33px — below one device pixel on a standard-density display. Raising the stroke to 2.5 or 3 before exporting keeps the shape solid; lowering it to 1.5 suits large app icons where a heavy stroke looks clumsy. The editor exposes this as a slider, so you can find the value that survives your smallest target size rather than guessing.

Using it in code

If you want the icon in a Vue project rather than as a downloaded asset, it is a named export of the lucide package:

import { Square } from 'lucide-vue-next'

<Square :size="24" :stroke-width="2" />

The download button above gives you something different: the icon composed onto a background with a corner radius, exported as a flat SVG path set. The exporter converts the icon out of its <foreignObject> wrapper first, because a foreign object taints an HTML canvas and would otherwise break PNG and ICO rasterisation.
