Do’s and don’ts
Rules written from the measurements, so a coding agent stays on style.
- Use #FFFFFF for the page and lift surfaces in small steps: #F8F8F8, #DEFDEE, #F5F5F5, #DEF5FF.
- Keep text in 4 levels: #191919, #091A2B, #0A1B2C, #292929.
- Reserve #0F2B46 for primary actions and key highlights.
- Set headlines in robotoLatin with tight tracking (-0.02em).
- Keep spacing on the 4px grid.
- Make buttons and chips fully rounded (9999px); most other elements use 8px corners.
- Introduce new font families beyond robotoLatin.
- Use #0F2B46 for large backgrounds or body text.
- Make interface transitions slower than 0.3s.

# DeepL Design System
## Overview
DeepL describes itself as: “Explore our AI suite and get more done: Translate speech, text, and media, or integrate the DeepL API.” The interface is light, built on **White (#FFFFFF)** with **Charcoal (#191919)** text, and **Deep Blue (#0F2B46)** as the main accent.
Type is set in **robotoLatin**. Headlines run large with tight negative tracking; body text is 16px. Depth comes from soft drop shadows. Controls are pill-shaped.
Measured from [deepl.com](https://www.deepl.com/en) on October 21, 2026 at 1440×900 and 390×844 from 434 rendered elements. Values are computed styles from the live page, not the original source files.
## Colors
The palette has 15 roles.
- **White (#FFFFFF):** Page background, seen 15 times. Token `background`.
- **Charcoal (#191919):** Primary text and headings, seen 11 times. Token `on-surface`.
- **Deep Blue (#091A2B):** Secondary text, seen 11 times. Token `on-surface-variant`.
- **Deep Blue (#0A1B2C):** Muted text and metadata, seen 3 times. Token `on-surface-muted`.
- **Graphite (#292929):** Subtle text and placeholders, seen 27 times. Token `on-surface-subtle`.
- **Snow (#F8F8F8):** Raised areas one step from the page, seen 1 time. Token `surface-container-low`.
- **Pale Teal (#DEFDEE):** Cards and panels, seen 1 time. Token `surface-container`, CSS `--dui-color-green-50-hex`.
- **Snow (#F5F5F5):** Hover and pressed fills, seen 1 time. Token `surface-container-high`, CSS `--dui-color-background-action-basic-raised-hover`.
- **Pale Cyan (#DEF5FF):** Highest raised elements, seen 11 times. Token `surface-container-highest`.
- **White 30% (#FFFFFF4D):** Translucent fill for cards and controls, seen 34 times. Token `overlay`.
- **Deep Blue (#0F2B46):** Primary buttons and calls to action, seen 29 times. Token `primary`.
- **Snow (#F5F5F5):** Text and icons on primary. Token `on-primary`.
- **Blue (#42A2FF):** Most used accent color, seen 15 times. Token `secondary`.
- **Blue (#0070C9):** Most used accent color, seen 14 times. Token `tertiary`, CSS `--dui-color-chart-status-info`.
- **Deep Teal (#004730):** Success and positive states, seen 1 time. Token `success`.
## Typography
**robotoLatin** carries the whole interface. Fallback stack: `robotoLatin, robotoLatin Fallback, sans-serif`. Other loaded fonts: robotoLatin Fallback.
- **display-hero:** robotoLatin 56px at weight 300, line height 1.05, tracking -0.021em. Oversized hero statements.
- **headline-display:** robotoLatin 48px at weight 300, line height 1.05, tracking -0.02em (28px on mobile). Page title (h1).
- **headline-lg:** robotoLatin 40px at weight 300, line height 1.05, tracking -0.018em. Section headings (h2).
- **headline-md:** robotoLatin 28px at weight 300, line height 1.15, tracking -0.017em. Sub-section headings.
- **body-md:** robotoLatin 16px at weight 400, line height 1.5. Body text.
- **body-lg:** robotoLatin 24px at weight 400, line height 1.4. Lead paragraphs.
- **label-md:** robotoLatin 16px at weight 600, line height 1.5. Buttons, navigation and labels.
- **label-sm:** robotoLatin 14px at weight 600, line height 1.43. Small labels and badges.
## Layout
Spacing follows a 4px grid: 91% of measured gaps and paddings are multiples of 4px.
- **Scale:** xs 4px, sm 8px, md 12px, lg 20px, xl 40px.
- **Gaps:** 8px is the most common gap in flex and grid layouts.
- **Breakpoints:** 512px, 767px, 869px, 1023px, 1280px, 1400px, 1615px.
## Elevation & Depth
Raised elements use soft drop shadows. The most used recipes:
- `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0.1) 0px 1px 4px 0px`
## Shapes
Interactive controls are pill-shaped. Measured radii, most used first:
- **full (9999px):** 216 elements.
- **sm (8px):** 160 elements.
- **md (12px):** 20 elements.
- **lg (16px):** 16 elements.
## Components
Measured from the rendered page. Token values reference the tokens above.
- **button-primary (“Close”):** #0F2B46 fill, #F5F5F5 text, 14px/600, 8px radius, padding 6px 12px, shadow `rgba(0, 0, 0, 0) 0px 0px 0px 1px inset`.
- **button-secondary (“Contact Sales”):** #3B435C fill, #FFFFFF text, 16px/600, 8px radius, padding 12px 20px, shadow `rgba(0, 0, 0, 0) 0px 0px 0px 1px inset`.
- **button-secondary-hover:** background #474E66, text #FFFFFF on hover.
- **button-ghost (“Products”):** transparent fill, #191919 text, 16px/500, padding 4px 0px 0px 0px.
- **card:** #091A2B fill, #191919 text, 16px/400, 16px radius, padding 0px.
- **link:** transparent fill, #3B435C text, padding 0px.
## Do's and Don'ts
- Do use #FFFFFF for the page and lift surfaces in small steps: #F8F8F8, #DEFDEE, #F5F5F5, #DEF5FF.
- Do keep text in 4 levels: #191919, #091A2B, #0A1B2C, #292929.
- Do reserve #0F2B46 for primary actions and key highlights.
- Do set headlines in robotoLatin with tight tracking (-0.02em).
- Do keep spacing on the 4px grid.
- Do make buttons and chips fully rounded (9999px); most other elements use 8px corners.
- Don't introduce new font families beyond robotoLatin.
- Don't use #0F2B46 for large backgrounds or body text.
- Don't make interface transitions slower than 0.3s.
## Motion
Interface transitions are quick: 0.15s, 0.3s, 0.25s.
- **Easing:** `cubic-bezier(0.4, 0, 0.2, 1)`, `ease-in-out`.
- **Reduced motion:** the page responds to `prefers-reduced-motion`.

What you can build with it
Landing pages, pricing tables, dashboards: your AI coding agent builds them in this style, with these colors, fonts, spacing and buttons instead of its defaults.
Download DESIGN.md, put it in your project’s root folder, then ask your agent for a page.
Build a landing page for my product. Follow for every color, font, spacing value, corner and button.
Need more than one page?
Design MD in the Sitepeel tools for Chrome measures pages behind a login, combines several pages into one file and works on any site you open.

Questions
What can I build with the DeepL DESIGN.md?
Any page or component in this style: a landing page, pricing table, dashboard or sign-up form. Your AI coding agent uses the measured colors, robotoLatin type, spacing, corners and buttons instead of its own defaults.
How do I use it with Claude Code or Cursor?
Download the file and put it in your project’s root folder, then ask your agent to follow DESIGN.md. Step-by-step guides: Claude Code, Cursor, Codex, GitHub Copilot.
Is this DeepL’s official design system?
No. Sitepeel measured it from deepl.com’s public page on October 21, 2026. It is an independent analysis, not made or approved by DeepL.
Can I use DeepL’s style in my own product?
Use it to learn, prototype and compare. For a real product, make the style your own, and never copy DeepL’s logo, name, pictures or text.
How accurate are the values?
Each value was measured on the rendered page after it fully loaded, on desktop and mobile: colors where they appear, type with tracking, spacing, corners, shadows and hover states. Sites change, so check the date at the top.
