# Readwise

> Extracted from [https://readwise.io/](https://readwise.io/) 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

Readwise uses a light canvas (#FBF9F3) with a palette led by #1D9BF0. Type is set in **Source Serif 4** (display + body), with 23px body text. Layout: 1200px container, top-sticky+transparent navigation, 12 sections. Built with google-tag-manager, 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` | `#FBF9F3` | 0.982 0.008 91.5 | bg | 72.4% | `--surface-primary` |
| `on-surface` | `#333333` | 0.321 0 0 | text | 16.0% | `--text-primary` |

| `button-neutral` | `#E8E6E1` | 0.925 0.007 88.6 | other | 0.05% | `--button-neutral` |

Sparse chromatic highlights (not accents): `#2675DE` (`--interactive-text`), `#EAB308`.

Contrast: text on background 12:1, muted text 4.07:1, accent 2.85:1.

Gradients in use: `linear-gradient(rgba(251, 249, 243, 0) 6.4%, rgba(251, 249, 243, 0.8) 82.8%), url("https://d34adp677peecb.cloudfront.net/static/images/landi`; `linear-gradient(rgb(245, 241, 232) 248.002px, rgb(251, 249, 243) 518.004px)`.

The site does not change under `prefers-color-scheme: dark`.

## Typography

| Family | Role | Weights | Share of text | Source |
|---|---|---|---|---|
| **Source Serif 4** | display, body | 400, 600 | 70.3% | webfont |
| **Albert Sans** | other | 400, 500, 600 | 19.1% | webfont |
| **Inter** | other | 400, 500, 600 | 8.9% | webfont |
| **Plus Jakarta Sans** | other | 400, 600, 700 | 1.7% | webfont |

Scale (px): 9.5, 12.5, 13, 14, 14.5, 16, 20, 22, 23, 24, 28.5, 32, 40, 54, 64. Effective ratio ≈ 1.186 (close to a minor third). Body 23px at line-height 1.417; display 64px with tracking -0.02em. Headings are sentence case. On a 390px viewport the body is 17px and display 39.69px.

## Layout

Spacing has no reliable single base unit; the most used steps are 3, 4, 5.5, 6, 7.5, 8.5, 10, 11, 12, 13, 14.5, 15.5, 16, 16.5px. Sections open with about 134px of space before their first line of text. Content sits in a 1200px container on a 2-column grid. Text density 0.415 (text area / page area).

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

1. **nav** (76px, bg #FBF9F3)
2. **hero** — “Meet , a book app unlike any other” (1634px, bg #022F2E)
3. **section** — “Remember” (312px, bg #FBF9F3)
4. **section** — “Revisit your highlights” (469px, bg #FBF9F3)
5. **section** — “Remember what you read” (469px, bg #FBF9F3)
6. **section** — “Organize your ideas” (469px, bg #FBF9F3)
7. **logos** — “Sync Readwise with your” (570px, bg #FBF9F3)
8. **testimonials** — “What our users say” (1167px, bg #FBF9F3)
9. **section** — “Do more with your highlights.” (837px, bg #FBF9F3)
10. **section** — “Everything you’ve read, away” (858px, bg #FBF9F3)
11. **testimonials** — “Start reading with superpowers” (599px, bg #FBF9F3)
12. **footer** — “Legal” (224px, bg #FBF9F3)

## Elevation & Depth

Style: subtle. Most used shadows:

- `rgba(0, 0, 0, 0.1) 0px 0.6px 0.6px 0px, rgba(255, 255, 255, 0.35) 1.5px 0px 1px 0px inset`
- `rgba(0, 0, 0, 0.1) 0px 2px 10px 0px inset`
- `rgba(42, 40, 34, 0.1) 0px 4px 4px 0px, rgba(42, 40, 34, 0.1) 0px 1.5px 1.5px 0px`

## Shapes

Dominant corner radius 11px; radii in use: 2px, 11px, 16px, 30.5px, pill. Borders: hairline (1px).

## Components

- **button-primary**: backgroundColor `#161616`, textColor `#FFFFFF`, rounded `9999px`, padding `10px 24px`, height `42px`, fontFamily `Albert Sans`, fontSize `16px`, fontWeight `600` (e.g. “Get Started For Free”)
- **card**: rounded `11.1px`, padding `11.1px`, backgroundColor `#FFFFFF`, border `1px solid #DBD7CD`

## Do's and Don'ts

- Do reserve `#1D9BF0` for primary actions and highlights; it covers only 0.09% of the painted page.
- Do set body copy in Source Serif 4 at 23px / 1.417.
- Do tighten large headlines (-0.02em at 64px).
- Don't introduce font weights beyond 400, 500, 600, 700.
- Do keep corners at 11px 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.
