Geometric Line Icons

Last Updated on August 11, 2026 by Editorial Team

A free set of 108 geometric line icons for your next application/website UI project. Props to Andy Kelly for creating and sharing these icons with the design community.

Scan through the grid and what stands out first is the discipline of the stroke weight. Every glyph, whether it’s the trophy, the shopping cart, the wallet, or the tiny musical note, sits on the same consistent line thickness with rounded joins and clean terminals.

That kind of uniformity is what separates a usable icon system from a random pile of symbols, and it’s exactly what makes this set of geometric line icons worth grabbing for interface work.

The style leans minimal and technical rather than decorative. Corners are kept sharp where the subject calls for it, like the calculator or the browser window, but curves stay soft and even, so the whole set reads as one coherent family instead of icons pulled from different sources.

There’s no fill, no shadow, no gradient trickery anywhere in the set. Just outline shapes built on what looks like a tight pixel grid, which keeps every icon crisp even at small sizes.

Because the linework is so restrained, these icons take on the color and personality of whatever interface you drop them into, which is a big part of their value as a UI kit component.

Where This Icon Set Performs Best

The subject matter covers a lot of ground that any product designer will recognize: navigation arrows, settings sliders, notification bells, lock and shield icons for security states, shopping and e-commerce symbols like the cart and price tag, and communication icons such as envelopes, chat bubbles, and the share glyph.

That breadth means you can build out a dashboard, a settings panel, an onboarding flow, or a checkout screen without hunting for a second or third icon pack to fill gaps.

The consistent geometry also makes this set a strong fit for mobile app UI, admin panels, SaaS marketing sites, and icon-driven feature lists on landing pages.

Anywhere you need small, legible visual cues next to text labels, this style of line icon does the job without competing for attention.

Because the mood stays neutral and technical rather than playful, it suits productivity tools, fintech products, analytics dashboards, and B2B software more naturally than it would a children’s app or a whimsical lifestyle brand.

If your product has a friendlier, rounder visual identity, you can still make these work by nudging stroke weight or corner radius to match, since the underlying shapes are simple enough to adjust without redrawing them from scratch.

When you bring icons like these into your working file, a few habits keep them looking sharp across a real interface.

• Keep every icon inside the same bounding box size before placing it, so visual weight stays even across a toolbar or menu.
• Adjust stroke color as a group rather than icon by icon, which keeps the set unified if you ever shift your palette.
• Test the icons at your actual target size early, since line icons can lose clarity if scaled down too far without adjusting stroke thickness.
• Pair them with a simple sans-serif type family so the geometric character of the icons carries through into your headings and labels.

These icons also pair naturally with card-based layouts, minimal color palettes, and generous white space, since that kind of composition lets the thin strokes breathe instead of getting lost against busy backgrounds.

If you’re assembling a broader design system, this set works well as the functional layer sitting underneath bolder brand colors, illustrations, or photography, giving structure to the UI without pulling focus from the content itself.
