Typography, UI & Design

Great design is built on systems, not individual decisions made one at a time. Whether you are choosing a color palette, calculating accessible contrast ratios, or building a modular type scale, having the right tools eliminates guesswork and makes your design both visually cohesive and technically correct. Our Typography, UI, and Design suite covers the mathematical foundations of professional visual design work.

Color Tools

The Color Picker and Converter lets you work with colors across HEX, RGB, HSL, and HSV formats. Designers frequently need to move between these formats when going from a design tool to CSS code, and doing it manually is error-prone and slow. Our converter makes this instant and works in both directions for any format combination.

The Color Picker from Image tool extracts exact color values from any uploaded photograph or screenshot. This is useful for matching colors from real-world references, building palettes inspired by photography, or reverse-engineering an existing brand's visual style from their website or printed materials.

Typography and Spacing

The Font Scale Generator creates a harmonious typographic scale based on a base font size and a ratio such as the Major Third (1.25) or Perfect Fourth (1.333). A modular scale gives you a complete set of size options for headings, body text, and captions that all relate proportionally to each other. This creates visual hierarchy that feels intentional rather than arbitrary.

The Fluid Typography CSS tool generates CSS clamp() declarations that smoothly scale font sizes between a minimum and maximum as the viewport changes width. This modern approach to responsive typography eliminates the abrupt size jumps that occur with older media query-based methods and is now the recommended approach for most responsive web projects.

Accessibility and Contrast

The WCAG Contrast Checker calculates the contrast ratio between any text color and background color and reports whether it passes WCAG 2.1 AA or AAA standards. Low contrast makes text unreadable for users with visual impairments or anyone viewing a screen in bright outdoor light. Accessible design is both a legal requirement in many jurisdictions and a mark of professional quality.

Web Content Accessibility Guidelines are published by the W3C Web Accessibility Initiative and represent the global standard for digital accessibility. Meeting these standards protects your users and reduces your legal exposure significantly.

Layout and Grid Tools

The CSS Grid System Generator creates the CSS code for a customizable column grid with specified gutters, margins, and column counts. The PX to REM Converter translates pixel values to relative units, which is essential for scalable accessible designs that respect users' browser font size preferences and work well across all screen densities.

The Golden Ratio Calculator computes proportional dimensions based on the 1.618 ratio found throughout nature and classic art. Use it to derive layout widths, image dimensions, and whitespace relationships that feel naturally balanced without being able to explain exactly why they look right to the viewer.
