# DESIGN.md: Calendly-style design system

Measured from https://calendly.com/ on 2026-10-15 by PikSpec (https://www.pikspec.com). An independent measurement of the rendered page, not Calendly's official design system, and not affiliated with Calendly.

Use it to build your own product in this design language: put this file in your project root and tell your AI tool (Claude Code, Cursor, Codex, Lovable, v0) to follow DESIGN.md. Never use the original's name, logo, copy or images; licensed fonts are replaced with the closest free Google Fonts.

To capture any other page, or get a ready project for your tool: https://www.pikspec.com/build-with-ai

HOW IT SHOULD LOOK
Build it in the design language of calendly.com, measured from the live site: it should feel designed by the same team as calendly.com — the same temperament, colour, type and density — for a different product. Never use calendly.com's name, logo, words or images.

Stack: use the one your project already has. Starting fresh: React + Vite + TypeScript + Tailwind CSS v4, with no UI kit (no shadcn/ui, MUI or Chakra) — their defaults would override this system. In a chat that shows one file (an artifact or canvas), build one HTML file instead, with the tokens below in its <style> block.
Use every value exactly as written. Do not round, rename, approximate or substitute a colour, size, radius, shadow or easing (fonts: see section 1). Anything not listed here does not exist in this system.

THE WEBSITE THIS SYSTEM COMES FROM
- Reference page: https://calendly.com/ — "calendly.com" (home page).
- Page frame: a top navigation bar and a footer.
- Content is grouped in cards (19 on the page, up to 4 side by side). Keep cards for grouped content only, not for every section.
- It uses 33 images, 27 of them large. Large, real product imagery is part of the look — leave clearly labelled image slots at those sizes rather than stock photos or abstract 3D shapes.
- Interaction: 66 buttons on one page.
- The page runs about 15 screens long at 1440px wide.
- Density is low: few elements per screen, generous space around each one.

HOW IT LOOKS (WHAT MAKES IT LOOK LIKE ITSELF, BEYOND THE VALUES)
- Almost entirely neutral: 99% of the page is painted in #FCFBF8 and #F5F3EE.
- #C3DFFE is an accent: 0.4% of the page, as small fills such as buttons and badges. Keep it to small areas.
- #D4C2FF is an accent: 0.2% of the page, as small fills such as buttons and badges. Keep it to small areas.
- The largest type (72px Calendly Sans) is medium weight, not bold (500), tracked to -0.028em.
- Open: text covers 7% of the page.
- Share of the painted page: #FCFBF8 74.7% (dominant, backgrounds); #F5F3EE 12.7% (dominant, backgrounds); #071A31 4.6% (supporting, backgrounds and text); #E4E6E9 3.8% (detail, backgrounds); #FFFFFF 2.4% (detail, backgrounds); #5F6D77 0.8% (supporting, text); #C3DFFE 0.4% (accent, backgrounds); #D4C2FF 0.2% (accent, backgrounds). Keep accents at these proportions; do not promote them to fills.
- Small marks: 5 small decorative marks (dots, crosses or ticks under 16px) in #071A31 and #D8DCE0, placed at corners and edges.
- Large images: Photographs, video or raster artwork cover about 21% of the page.
- Type as set (size, weight and tracking measured together; use these pairs): 72px weight 500 tracking -0.028em; 60px weight 500 tracking -0.033em; 48px weight 500 tracking -0.042em; 36px weight 500 tracking -0.028em; 28px weight 500; 24px weight 500.

1. DESIGN TOKENS — PASTE INTO YOUR GLOBAL CSS
Allowed colours, with how the original uses each. Use no other colour, including in hover states:
- #FCFBF8 — 74.7% · backgrounds (var(--color-background))
- #F5F3EE — 12.7% · backgrounds (var(--color-f5f3ee))
- #071A31 — 4.6% · backgrounds, text (var(--color-action))
- #E4E6E9 — 3.8% · backgrounds (var(--color-e4e6e9))
- #FFFFFF — 2.4% · backgrounds (var(--color-on-action))
- #5F6D77 — 0.8% · text (var(--color-text-muted))
- #C3DFFE — 0.4% · backgrounds (var(--color-c3dffe))
- #D4C2FF — 0.2% · backgrounds
- #6BB1FF — 0.1% · backgrounds
- #F2F8DE — 0.1% · backgrounds
- #D8DCE0 — hairlines and grid lines (var(--color-surface))
- #0C2D54 — hairlines and grid lines
- #000000 — Text (var(--color-text))
- #BAF0EC — Positive (var(--color-positive))
Fonts — put these first in your global CSS (one import per font, so one that fails cannot stop the others):
```css
@import url("https://fonts.googleapis.com/css2?family=Geist:wght@400;500;600;700&display=swap");
@import url("https://fonts.googleapis.com/css2?family=Figtree:wght@500&display=swap");
```
Font: calendly.com uses Calendly Sans (display) and Wulkan Text (interface) — its own licensed faces, not available to download. This kit uses Figtree for display and interface, the closest free match, already in the tokens. If you own the original, add it with @font-face and it is used first; to use another font, change the --font-* variables.
Geist is on Google Fonts and loaded from there.
Keep every size, weight, line height and tracking exactly as listed whichever font renders.

Tailwind CSS v4 (the default for new projects): put this after `@import "tailwindcss";`. It removes Tailwind's own palette, so only these colours exist as utilities:

Tailwind CSS v3 only: extend the theme with these instead, and use no other palette:
```js
// tailwind.config — theme.extend
{
  colors: { "background": "var(--color-background)", "surface": "var(--color-surface)", "text": "var(--color-text)", "text-muted": "var(--color-text-muted)", "border": "var(--color-border)", "action": "var(--color-action)", "on-action": "var(--color-on-action)", "link": "var(--color-link)", "positive": "var(--color-positive)" },
  fontFamily: { "body": ["var(--font-body)"], "display": ["var(--font-display)"], "interface": ["var(--font-interface)"] },
  borderRadius: { "xs": "var(--radius-xs)", "sm": "var(--radius-sm)", "md": "var(--radius-md)", "lg": "var(--radius-lg)", "xl": "var(--radius-xl)", "2xl": "var(--radius-2xl)", "3xl": "var(--radius-3xl)" },
  boxShadow: { "e1": "var(--elevation-1)", "e2": "var(--elevation-2)", "e3": "var(--elevation-3)", "e4": "var(--elevation-4)" },
}
```

2. BASE STYLES
```css
html { background: var(--color-background); }
body { margin: 0; font-family: var(--font-body); font-size: var(--type-body-large); line-height: var(--type-body-large-leading); color: var(--color-text); -webkit-font-smoothing: antialiased; -moz-osx-font-smoothing: grayscale; }
h1, h2, h3 { font-family: var(--font-display); margin: 0; }
a { color: var(--color-link); }
:focus-visible { outline: 2px solid var(--color-action); outline-offset: 2px; }

```
Where a component lists recorded states, write those states using only the colours above; the capture saw that the state exists, not its values. Never invent a state colour.

4. PAGE COMPOSITION
- Light interface on #FCFBF8. Keep that ground; do not add a dark mode or alternate section backgrounds the system does not have.
- The opening screen carries a large image or video beside the heading. Leave a [content: hero image or video] slot there, at least half the screen wide; the opening is not text alone.
- #071A31 is the action colour. Fill the primary action with it and little else — at most one #071A31-filled element per screen; other accents keep to the uses listed above.
- Type: Geist for body; Figtree (standing in for Calendly Sans) for display; Figtree (standing in for Wulkan Text) for interface. Hierarchy comes from size and weight, not colour or decoration.
- Everything sits on a 4px grid.
- Corner radii are 1px, 2px, 3px, 4px, 8px, 12px, 16px — nothing else.
- Body text uses Geist at around 16px, weights 400, 500, 600, 700.
- Headings use Calendly Sans; the largest heading is 72px.
- Primary buttons are #071A31, 16px radius, weight 400.
- Cards use 64px corners.
- Corner radii in use: 24px, 8px, 4px, 64px, 48px.

HOW THE ORIGINAL PACES ITS PAGE (BORROW THE RHYTHM — THE OPENING, THE COLOURED BANDS, THE CARD GRIDS — NOT THE LIST; BUILD THE SECTIONS YOUR PRODUCT NEEDS)
1. Hero — 348px tall, centred 72px heading (weight 500).
2. Split — about 900px tall (the original scroll-animates this band over 3011px; build it as one screen), split 5 / 7, 64px gap, left-aligned 36px heading (weight 500), image behind the content.
3. Cards — 1209px tall, split 2 / 4 / 3 / 3, 24px gap, centred 60px heading (weight 500), image behind the content, on #FCFBF8.
4. Text — 1927px tall, left-aligned 48px heading (weight 500), image on the right.
5. Split (×3) — 3 bands of 820px, 2 equal columns, 80px gap, left-aligned 48px heading (weight 500), image on the left, on #FCFBF8.
6. Cards — 1089px tall, split 1 / 1 / 8 / 1 / 1, 20px gap, centred 60px heading (weight 500), image behind the content.
7. Split — 1068px tall, 2 equal columns, 24px gap, centred 60px heading (weight 500), on #FCFBF8.
8. Cards — 1070px tall, 3 equal columns, centred 60px heading (weight 500), image centred, on #FCFBF8.
9. Footer — 1038px tall, split 5 / 7, 136px gap, left-aligned 60px heading (weight 500), on #FCFBF8.
- Content sits in a 1280px container, 120px from the edge at 1440px wide.
- A 108px header scrolls away.
- The hero is 348px (0.4 screens): centred 72px heading (weight 500).
- Column splits on a 12-column grid: 5/7 (2×), halves (2×), 2/4/3/3, 1/1/8/1/1; gaps of 24px.
- Headings mix left (4) and centred (5) alignment.
- Sections share one background; they are separated by space and lines, not colour bands.
- A typical section is about 1089px tall.

COPY SHAPE (MATCH THE LENGTH AND CASE; WRITE YOUR OWN WORDS)
- The main heading is 6 words long.
- Section headings are medium length: typically 6 words.
- Headings are in sentence case (only the first word capitalised).
- The page describes itself in about 22 words; keep your intro paragraph to about that length.

5. MOTION
Interactive elements change colour, background, border and opacity with the measured timing. Animate nothing else.
```css
a, button, [role="button"], input { transition: color var(--duration-1) var(--ease-1), background-color var(--duration-1) var(--ease-1), border-color var(--duration-1) var(--ease-1), opacity var(--duration-1) var(--ease-1); }
@media (prefers-reduced-motion: reduce) {
  *, *::before, *::after { animation-duration: 0.01ms !important; animation-iteration-count: 1 !important; transition-duration: 0.01ms !important; scroll-behavior: auto !important; }
}
```
No scroll-triggered fade-ins, parallax, typewriter text or bouncing elements.

6. RESPONSIVE
- The design was measured at 1440px wide. Lay it out for that width first, then let it reflow down to 360px.
- Content sits in a column at most 1280px wide, centred, with var(--space-4) (16px) side padding on small screens.
- The largest heading scales fluidly: font-size: clamp(36px, 5vw, 72px). Every other size stays fixed.
- Break on composition, not device names: a row of columns drops a column when any column would be narrower than 240px; side-by-side splits stack when either side would be narrower than 320px.
- Spacing steps never change between sizes; use smaller steps from the same list where space is tight.
- On touch screens, every link and button has a hit area of at least 44 × 44px without changing its drawn size.

7. ACCESSIBILITY
- Text pairs that pass for body copy: Text on Background (20.3:1), Text muted on Background (5.2:1), Action on Background (16.9:1), Link on Background (16.9:1), Text on Surface (15.2:1), Action on Surface (12.7:1), Link on Surface (12.7:1) and On action on Action (17.5:1).
- Only for text 24px and up, or 18.66px bold: Text muted on Surface (3.9:1).
- Use no other text-on-background pairing.
- One h1 per page, headings in order, landmarks (header, nav, main, footer), real buttons and links, a label on every field, alt text on every image, an aria-label on icon-only buttons.
- Every interactive element shows the :focus-visible outline above.

8. DO NOT (THESE ARE WHAT MAKE AI-BUILT SITES LOOK GENERIC)
- No gradients: not in backgrounds, text, buttons or borders. (No gradient was measured.)
- Only these colours: #FCFBF8, #F5F3EE, #071A31, #E4E6E9, #FFFFFF, #5F6D77, #C3DFFE, #D4C2FF, #6BB1FF, #F2F8DE, #D8DCE0, #0C2D54, #000000, #BAF0EC. No new tints, no Tailwind defaults (slate, indigo, violet). (They are every colour that covers a measurable part of the page, and the colours its lines and drawings use.)
- #C3DFFE only as small fills (buttons, badges) — never a section background or a large panel. (It covers 0.4% of the page.)
- #D4C2FF only as small fills (buttons, badges) — never a section background or a large panel. (It covers 0.2% of the page.)
- Only the fonts in the tokens: Geist for body; Figtree for display; Figtree for interface. No other typeface, and no Inter, Roboto or system UI font unless it is one of these. (The page is set in Calendly Sans and Geist and Wulkan Text; the tokens carry what stands in for them.)
- Headings and large text never heavier than weight 500. Do not make headlines bold to add emphasis. (Every size from 24px up is set at weight 500 or lighter.)
- Large headlines tracked tight (letter-spacing -0.028em), not at the browser default. (The 72px headline is set at -0.028em.)
- No icon above every feature, no emoji, no decorative blobs, sparkles or glows. (None of these is part of the captured design; they are a coding model's defaults.)
- Build the sections your product needs, not the original's list. Give each one this system's look: its kinds of section (hero, split, cards, text, footer), its colours, type, shapes and spacing. (The style carries to any kind of site; the original's page was for a different product.)
- No glassmorphism, backdrop blur, glowing orbs, noise blobs or neon outlines.
- No row of three identical feature cards as the default section. Vary the layout from section to section: a split, a list, a single large statement, a table.
- No centred-everything hero with a pill badge, a gradient headline and two buttons. Lead with the most specific thing about the product.
- No filler copy: no "Unlock your potential", "Revolutionize", "Seamless", "Elevate", "Supercharge", "Next-gen" or lorem ipsum. Write plain, specific sentences a real company would publish.
- No made-up statistics, testimonials or customer logos. Leave a clearly marked [content: …] slot instead.
- No radius larger than the largest one listed.
- No shadows other than the levels listed.
- Do not use calendly.com's name, logo, copy or images. This is its design system, not its content.

BEFORE YOU FINISH
- Search your code for every colour, font size, spacing value, radius, shadow and easing, and replace anything that is not a variable above.
- Check that no [content: …] slot has been filled with invented facts.
- Search your CSS for gradient(. There should be none.
- Every colour value in your CSS is one of the allowed colours. Nothing else, including in hover states.
- #C3DFFE covers about 0.4% of the page or less, as on the original.
- #D4C2FF covers about 0.2% of the page or less, as on the original.
- No text 24px or larger has a font-weight above 500.
- The largest headline uses letter-spacing -0.028em.
- Every section, including ones the original does not have, uses only this system's colours, type, shapes and spacing.
- Content sits in a 1280px container with 120px side margins at 1440px.
- There is no placeholder copy (lorem ipsum, "Feature one", "Your headline here"). Every word is real.
- Take a screenshot at 1440px and put it beside the original. List every difference in colour, weight, spacing, alignment and imagery, and fix each before finishing. Then check 390px wide: nothing scrolls sideways and no heading runs off the screen.
