<p>Flex is all about the curves. Its smooth curves brings fluidity and dynamism to your designs with a modern appeal.&nbsp;The Remix style is ideal for designs that require a distinct look without overwhelming the overall aesthetic.&nbsp;All Flex Remix icons are designed on a 14px grid with a mix of outlined and filled shapes.</p>

Flex Remix

<p>Flex is a fluid icon family inspired by nature’s curves. It favors smooth, flowing forms. More organic than Core and subtler than the chunky Plump. Read about the <a href="https://blog.streamlinehq.com/flex/" rel="noopener noreferrer" target="_blank">design process</a>.</p>

### **one sentence positioning**

Organic curvilinear icons that feel natural and motion-ready, with curves built into every path rather than added only at caps.

---

### **what it signals**

Human friendliness with control, calm modern energy, fluidity without cuteness.

---

### **best fit when**

- a friendly, modern tone with organic curves is needed without sacrificing legibility
- motion is a core part of the product's personality
- multiple variants are needed that each occupy a clear and distinct hierarchy role

---

### **avoid when**

- the least opinionated, most neutral system is required — use Core or Ultimate instead
- the brand must feel severe, industrial, or technically uncompromising
- enterprise-heavy surfaces risk being over-personalised without visual discipline

---

### **core visual rules**

- geometry: continuous curvilinear forms — strokes arc, bend, and flow rather than running straight between rounded endpoints
- terminals: rounded ends throughout
- corner language: squircle / soft curved logic — the curves are in the paths, not just the caps
- curves: continuous curvilinear — nature-inspired flowing construction throughout
- detail density: low
- silhouette: stable and inflated; the organic construction avoids fragile details
- emotional tension: low — the flow reads as natural rather than energised

---

### **variants and hierarchy**

Flex Line

- Most neutral; lets typography and layout lead; the organic curves carry the warmth quietly in the background

Flex Solid

- Impact and legibility; survives small sizes well; the primary state and hierarchy tool in the family

Flex Remix

- Outlined + filled in organic shapes; brand identity and editorial feature sections

Flex Pop

- Organic curves + multi-color palette; consumer apps with nature, food, or sustainability positioning

Flex Duo

- Blue tonal system + organic curves; fintech and professional wellness wanting approachability with structure

Flex Neon

- 1px organic strokes + magenta + navy; the most sophisticated neon treatment — thin organic lines in neon read as high-design, not gaming

Flex Flat

- Smooth organic silhouettes; illustrative onboarding, wellness storytelling, and product education

Flex Gradient

- Organic shapes + watercolour-quality naturally blended fills; premium lifestyle and beauty marketing

**line/solid pairing rule** Mix Line and Solid to express state — Line for inactive or default, Solid for selected, active, or emphasis. The continuous curve construction means both sub-styles read as the same family despite the weight difference.

---

### **small-size behavior**

- recommended minimum size: 18px
- best range: 18–36px
- notes: Below 18px the organic curves lose their distinguishing quality and read as simply "rounded" — the family's primary characteristic disappears at very small sizes.

---

### **motion behavior**

- strengths: continuous shapes reduce jitter during scaling; smooth and natural morphs between states
- ideal motion contexts: button feedback, toggle animations, success states, onboarding transitions, Line-to-Solid state changes, loading loops with flowing character

---

### **typography pairing**

Rounded and friendly

- SF Pro Rounded, Avenir Next Rounded, Museo Sans Rounded, GT Walsheim, Sofia Pro Soft

Modern and curvy but still serious

- Palanquin, Bree Sans, Signika, Plus Jakarta Sans, Nunito

Free rounded options

- Rubik, Quicksand, Varela Round, M PLUS Rounded 1c, Outfit

**type alignment rule** Typefaces with smooth curves and open counters match better than rigid neo-grotesques. The organic curve construction of the icons should be reflected in the letterforms — look for typefaces where the 'a', 'e', and 'g' have visible curve intelligence rather than geometric construction.

**typefaces to avoid** Cold geometric sans with rigid structure (IBM Plex Sans, Neue Haas Grotesk), monospace fonts, sharp display faces — the organic icon curves create irresolvable tension against any type whose letterforms are built on straight lines and hard angles.

---

### **mixing guidance**

Recommended with

- Micro — Flex handles UI personality while Micro handles the density and inline layer
- Freehand — both are organic warmth families; separate by surface (Flex for UI, Freehand for editorial)

Possible with normalization

- Plump — both warm families; keep one per UI layer and reduce chroma if mixing
- Ultimate — normalize by isolating Flex to primary navigation and Ultimate to secondary controls

Avoid mixing with

- Sharp — organic curves directly contradict geometric angular construction
- Cyber — straight-line-only Cyber is the opposite of Flex's continuous curve philosophy
- Block — Bauhaus geometric solids are incompatible with organic flowing silhouettes

**normalization rules when mixing**

- keep Flex consistent within a UI layer — no family switching inside a single navigation component
- reduce chroma (use monochrome Line or Solid) if pairing with severe typography or brand system
- isolate other families to separate surfaces — product UI in Flex, marketing or documentation in another

---

### **primary use cases**

- consumer and lifestyle applications
- education products and learning platforms
- wellbeing products that are non-clinical in register
- creator tools and motion-forward product UIs
- onboarding and tutorial flows where warmth reduces friction
- premium consumer SaaS with an organic or nature-adjacent brand

---

### **secondary use cases**

- empty states and feature callouts (especially Flat sub-style)
- brand-friendly UI accents and state systems using Line/Solid/Duo patterns
- products wanting organic visual confidence without moving into hand-drawn territory
