<p>Plump is highly inspired by cartoons. With its warm appearance, this set of chunky icons is a natural choice for friendly brands.&nbsp;The Duo style is perfect for projects that require differentiation between actions, using color to convey meaning effectively. It also allows you to customize the line thickness.&nbsp;All Plump Duo icons are designed on a 48px grid with a 3px default stroke and two customizable colors.</p>

<p>100% cute and playful. Features subtle curves and chunky shapes inspired by animated cartoons. Recommended for friendly brands.</p>

### **one sentence positioning**

Warm, inflated, cartoon-inspired icons on a 48px grid — friendly enough to ship as consumer UI without losing legibility.

---

### **what it signals**

Friendliness, approachability, optimism, guided clarity, delight, safety.

---

### **best fit when**

- a warmer product tone is needed without abandoning system discipline
- icons must remain clearly readable on mobile in dense navigation contexts
- soft, confident curves and generous visual weight signal approachability to non-technical users

---

### **avoid when**

- strict enterprise neutrality or heavy technical authority is required
- the product communicates cybersecurity seriousness or industrial precision
- an invisible, neutral icon layer is the design goal

---

### **core visual rules**

- geometry: rounded, generous, inflated — shapes approach pill forms throughout
- terminals: soft / fully rounded — pill-like caps on all line variants
- corner language: fully-rounded, approaching pill shapes; no sharp angles anywhere
- curves: smooth continuous curves; the 48px grid creates proportionally wider internal paths
- detail density: low
- silhouette: strong, stable, inflated — never fragile; reads as animation-adjacent
- emotional tension: very low — the inflated proportions communicate play and safety simultaneously

---

### **variants and hierarchy**

Plump Line (3px)

- Consumer navigation; the most warm and self-announcing line weight in this review; active at any density

Plump Solid

- Feature highlights, mobile tab bars, promotional app store graphics; illustration-level presence

Plump Remix

- Outlined + filled mix, fully rounded; graphic identity for friendly consumer brands without colour

Plump Pop

- High-saturation multi-color; children's apps, gamification badges, promotional campaigns

Plump Duo (3px line + blue tonal)

- Consumer SaaS wanting warmth with colour discipline; onboarding with colour-based attention guidance

Plump Neon (3px + magenta + navy)

- Gaming, youthful entertainment, high-energy dark-mode promotional materials

Plump Flat

- Chunky two-tone blue silhouettes; illustrative onboarding and feature explainers at display sizes

Plump Gradient

- Full-spectrum fills in inflated shapes; the most celebratory sub-style in any family in this review

**line/solid pairing rule** Plump Line for navigation and content contexts; Plump Solid for feature callouts and active tab states. The 3px stroke ensures Line is never invisible, so the hierarchy shift to Solid is about emphasis, not legibility.

---

### **small-size behavior**

- recommended minimum size: 20px
- best range: 20–64px
- notes: The 48px proportions and 3px stroke weight are self-announcing above 20px. Below this, the inflated construction loses its distinctive quality and reads simply as rounded rather than cartoon-inspired.

---

### **motion behavior**

- strengths: fluid scaling, smooth transitions, low jitter; the inflated shapes scale without visual noise
- ideal motion contexts: tab transitions, onboarding step animations, empty-state reveal, hover feedback on feature callouts, celebration states and achievement unlocks

---

### **typography pairing**

Soft humanist / rounded sans

- Nunito, Sofia Pro, Avenir Next Rounded, Rubik, Fredoka

Structured but compatible

- Manrope, Plus Jakarta Sans, General Sans, Outfit, Poppins

**type alignment rule** Match the roundness — fonts with rounded terminals or explicitly circular letterforms pair most naturally with Plump's pill-shaped constructions. The type must carry the same visual weight as the 3px stroke; hairline fonts are overwhelmed.

**typefaces to avoid** Cold geometric sans (IBM Plex Sans, Neue Haas Grotesk, Space Grotesk), serif at any weight, monospace — all create a register mismatch against the warm cartoon construction. The contrast reads as unresolved, not as intentional tension.

---

### **mixing guidance**

Recommended with

- Stickies — both operate in the consumer-delight register; separate by deployment size

Possible with normalization

- Flex — both are warm families; normalize by keeping Plump in navigation and Flex in marketing
- Freehand — both communicate warmth; keep one per product layer to avoid tonal redundancy

Avoid mixing with

- Sharp — polar geometry; inflated vs angular is an unresolvable visual contradiction
- Cyber — the extreme technical coldness of Cyber is incompatible with Plump's warmth
- Micro — scale and proportion gap is too extreme for the same product layer

**normalization rules when mixing**

- keep Plump consistent within primary consumer navigation if used for UI chrome
- avoid mixing with sharp angular families in any shared component
- isolate contrasting families to separate surfaces — Plump for product, another for marketing or documentation

---

### **primary use cases**

- consumer apps and mobile-first onboarding flows
- children's education and learning platforms
- health, wellness, and lifestyle products
- consumer fintech where approachability reduces drop-off
- community and social platforms where warmth signals belonging
- any product where icon legibility for non-technical users is critical

---

### **secondary use cases**

- marketing websites and consumer landing pages
- empty states and feature illustration surfaces
- sticker systems, badge designs, and gamification rewards
