<p>Ultimate is the world’s largest icon family, designed by 8 expert designers. The Duotone style enhances visual depth by combining colored lines and filled shapes, perfect for matching brand or project colors. Key advantages: 1—Customizable colors. Apply up to four different colors to icon elements. 2— Adjustable stroke thickness. Create looks ranging from thin to bold for varied aesthetics.</p>

<p>The world's largest icon family with encyclopedic coverage. Designed over twelve years, Ultimate offers every concept from common to rare icons. It's a neutral style and fits most use cases.&nbsp;</p>

### **one sentence positioning**

The safest default, with 16,500+ icons covering virtually every product category in a neutral rounded geometry designed to scale across teams and years.

---

### **what it signals**

Reliability, professionalism, visual calm, adaptability, completeness.

---

### **best fit when**

- maximum coverage and long-term system stability are the priority
- neutrality must fit across a wide range of product categories without imposing a visual identity
- minimising icon source mixing across large teams is a business requirement

---

### **avoid when**

- strong brand personality or stylistic differentiation at the icon layer is needed
- hand-drawn warmth, highly playful consumer tone, or brutalist technical stance is required
- icons are meant to act as decorative or illustrative marketing elements

---

### **core visual rules**

- geometry: smooth controlled curves, harmonious proportions, humanist rounded construction
- terminals: rounded throughout — no sharp or flat caps
- corner language: rounded, consistent across all sub-styles
- curves: mathematical arcs with soft, controlled construction
- detail density: low to medium
- silhouette: clear, readable, calibrated for dense UI comfort — never fragile
- emotional tension: low — the neutrality is the point

---

### **variants and hierarchy**

Ultimate Light (1px)

- Refined editorial contexts, sparse UI, premium SaaS with generous spacing; the most delicate sub-style

Ultimate Regular (1.5px)

- Primary UI navigation and dashboards; the safest general-purpose choice across any product category

Ultimate Bold (solid)

- Mobile tab bars, active states, small-size legibility contexts, feature callouts

Ultimate Duotone

- Three-layer: colored stroke + tint fill + selective white; feature marketing and onboarding flows

Ultimate Colors

- Multi-color flat fills per element; consumer marketing and illustrative onboarding contexts

**line/solid pairing rule** Light and Regular handle inactive and standard states; Bold handles active, selected, and emphasis states. All three share the same shape vocabulary so hierarchy is expressed purely through weight, never through shape inconsistency.

---

### **small-size behavior**

- recommended minimum size: 14px
- best range: 16–32px
- notes: Regular and Bold hold reliably across the range; Light approaches legibility limits below 16px on dark backgrounds and requires near-white color with sufficient contrast.

---

### **motion behavior**

- strengths: stable scaling, clean opacity transitions, smooth line-to-solid weight morphs
- ideal motion contexts: tab bar transitions, loading states, hover feedback, onboarding step progressions, feature reveal animations

---

### **typography pairing**

Neo-grotesque / Swiss-style neutrality

- Inter, Helvetica Neue, Neue Haas Grotesk, Univers, Graphik, Suisse Int'l, Aktiv Grotesk

Geometric sans (more branded but compatible)

- Montserrat, Poppins, DM Sans, Urbanist, Space Grotesk, Avenir, Proxima Nova

**type alignment rule** Pair with stable, neutral, UI-optimised typography — the Helvetica mindset applied to icon systems. The icons are designed to disappear into the interface; the type should support that intent rather than fight for attention.

**typefaces to avoid** Decorative display fonts, handwritten scripts, highly humanist serif faces, overly playful rounded fonts — any type with strong personality risks overriding the deliberate neutrality of the icon system.

---

### **mixing guidance**

Recommended with

- Micro — use Micro as the density layer for tables and inline actions while Ultimate handles primary UI
- Nova — compatible neutral geometry; normalize by keeping one family per UI layer

Possible with normalization

- Core — both are neutral rounded families; separate by component or surface to avoid overlap
- Streamline 3.0 — similar rounded DNA; keep one family per product section

Avoid mixing with

- Freehand — hand-drawn organics contradict the calibrated precision of Ultimate
- Plump — inflated cartoon proportions create weight imbalance
- Kameleon — flat illustration containers have a categorically different visual register

**normalization rules when mixing**

- use Ultimate as the primary UI infrastructure layer across navigation, toolbars, and forms
- isolate secondary families to marketing surfaces, empty states, or onboarding
- never mix Ultimate and another family within the same navigation component

---

### **primary use cases**

- SaaS dashboards and admin panels at any scale
- mobile app navigation and product interfaces
- design systems requiring comprehensive multi-category coverage
- enterprise software, settings panels, and navigation systems
- onboarding flows and feature navigation
- component libraries built to serve multiple product teams
- B2B and productivity applications

---

### **secondary use cases**

- marketing websites and pitch decks
- product documentation and knowledge bases
- internal tooling and analytics interfaces
