# Cal.com

> Extracted from [https://cal.com/](https://cal.com/) on 2026-11-12 by Emblematic. Every value below was read from the rendered DOM (computed styles, `document.fonts`, and the fonts Chrome actually used to paint text), not estimated from pixels. When the YAML front matter and this prose disagree, the YAML wins. Copy values from this file exactly; don't transcribe them from memory. Don't copy logos, imagery, illustrations or marketing copy.

## Overview

Cal.com uses a light canvas (#FFFFFF) with a palette. Type is set in **Cal Sans** (display + body), **Menlo** (mono), with 17px body text. Layout: 1320px container, top-sticky+blur navigation, 18 sections. Built with next.js, tailwind, shadcn/ui, storyblok, posthog, vercel, cloudflare.

## Colors

Area-weighted from painted backgrounds, text and borders on the 1440px light capture. Roles are inferred from usage (largest background, most text, interactive fills). Every hex is an exact computed value; a role marked *unverified* is a best guess that has not passed review, so its canonical token (e.g. `primary`) is left out of the front matter.

| Token | Hex | OKLCH | Role | Share of paint | CSS variable |
|---|---|---|---|---|---|
| `background` | `#FFFFFF` | 1 0 0 | bg | 62.1% | `--background` |
| `surface` | `#F3F4F6` | 0.967 0.003 264.5 | surface | 9.0% | `--chart-background` |

| `color-16` | `#FFFFFF0F` (on bg `#FFFFFF`) | 1 0 39 | other | 0.10% | — |

Sparse chromatic highlights (not accents): `#F5A524`.

Declared brand/accent tokens: `--color-hp-accent` = `#CC4510`, `--color-hp-accent-ink` = `#A83A0C` (declared, not painted on this page).

Contrast: text on background 15.52:1, muted text 3.5:1, accent 15.52:1.

Gradients in use: `linear-gradient(rgba(0, 0, 0, 0), rgba(17, 17, 17, 0.55))`; `linear-gradient(90deg, rgb(106, 110, 120) 35%, rgb(36, 36, 36) 50%, rgb(106, 110, 120) 65%)`.

The site responds to `prefers-color-scheme: dark`; the `-dark` tokens hold the dark-mode roles.

## Typography

| Family | Role | Weights | Share of text | Source |
|---|---|---|---|---|
| **Cal Sans** (CSS: `calSans`) | display, body | 400, 500, 700 | 94.1% | webfont |
| **SF Pro (system-ui)** (CSS: `-apple-system`) | other | 400, 500, 600 | 5.4% | system (stack `-apple-system, "system-ui", "SF Pro Text", "SF Pro", system-`, resolved on macos) |
| **Menlo** (CSS: `ui-monospace`) | mono | 400, 500 | 0.40% | system (stack `ui-monospace, "SF Mono", Menlo, Consolas, monospace`, resolved on macos) |

Scale (px): 12, 12.5, 13, 14, 15, 17, 18, 19, 20, 24, 56, 80. Effective ratio ≈ 1.295 (close to a perfect fourth). Body 17px at line-height 1.45; display 80px with tracking -0.01em. Headings are sentence case. On a 390px viewport the body is 17px and display 42px.

## Layout

Spacing has no reliable single base unit; the most used steps are 2, 4, 6, 8, 10, 11, 12, 14, 16, 20, 24, 40, 60, 128px. Sections open with about 128px of space before their first line of text. Content sits in a 1320px container on a 2-column grid. Text density 0.106 (text area / page area).

Section order (desktop). Kinds below the review threshold are shown as *section*:

1. **nav** (64px, bg #F7F7F7)
2. **hero** — “Where people find the time to meet” (677px, bg #FFFFFF)
3. **section** (982px, bg #FFFFFF)
4. **section** — “Now it's one link. Finding a time took a week of emails.” (1024px, bg #FFFFFF)
5. **section** — “wherever you ask. One assistant,” (311px, bg #FFFFFF)
6. **section** — “Bookings since September” (766px, bg #FFFFFF)
7. **section** — “every way people meet. One calendar for” (1590px, bg #FFFFFF)
8. **section** — “in sync with your meetings. All your key tools” (1559px, bg #FFFFFF)

10. **section** — “that meet at scale. Trusted by teams” (306px, bg #FFFFFF)
11. **testimonials** — “Kiaora runs mission-critical healthcare scheduling across states. Kiaora” (1337px, bg #FFFFFF)
12. **section** — “love Cal.com. See why our users” (462px, bg #FFFFFF)
13. **testimonials** (1017px, bg #FFFFFF)
14. **section** — “Events takes the whole room. Hosting more than a meeting?” (1327px, bg #FFFFFF)
15. **section** — “actually adopts. Scheduling the whole company” (1035px, bg #FFFFFF)
16. **faq** — “questions. Frequently asked” (822px, bg #FFFFFF)
17. **logos** — “Scheduling for absolutely everyone.” (855px, bg #FFFFFF)
18. **footer** (1536px, bg #111111)

- **input**: rounded `0px`, height `38px`, padding `4px 0px`

## Do's and Don'ts

- Do set body copy in Cal Sans at 17px / 1.45.
- Do tighten large headlines (-0.01em at 80px).
- Don't introduce font weights beyond 400, 500, 600, 700.
- Do keep corners at 8px for most controls, and use the larger radii only for cards and media.
- Don't copy this site's logos, illustrations, photography or copy; use the system, not the brand assets.
