Sassy Modular Scale

Put down the calculator and let Sass do the work.

Sassy Modular Scale is a Sass based mixin that calculates the incremental values of the modular scale in proportion to a set size and ratio. It was inspired by and adapted from Tim Brown's modularscale.com.

Sassy Modular Scale can be used as a Compass extension and can be installed as a Ruby gem.

Installation

Usage requires Sass. Visit sass-lang.com to learn more and install.

gem install modular-scale

Then add require 'modular-scale' to your Compass config file.

Alternative installation (without Compass)

Compass provides a way for Sass mixins to be easily required into a project, but we also support the following:

• Copy either stylesheets/_modular-scale.sass or stylesheets/_modular-scale.scss into your project's Sass directory
• Import the file into your Sass stylesheet to access the mixins and functions. For example, @import vendor/modular-scale

Usage

Sassy Modular Scale can be used as a function, mixin or a mixin that generates a range of classes to @extend.

Examples using the Sass syntax:

// Use as a function. Fill in the multiple, base-size, and ratio
height: modular-scale(7, 14px, $golden)

// Use as a mixin. Fill in the property, multiple, base-size, and ratio
+modular-scale(line-height, 1, 14px, $golden)

// This method will generate a range of classes to `@extend`
+modular-scale-classes(6)

[role="main"]
  h1
    @extend .ms-2
  h2
    @extend .ms-1
  h3
    @extend .ms-0

Examples using the SCSS syntax:

// Use as a function. Fill in the multiple, base-size, and ratio
height: modular-scale(7, 14px, $golden);

// Use as a mixin. Fill in the property, multiple, base-size, and ratio
@include modular-scale(line-height, 1, 14px, $golden);

// This method will generate a range of classes to `@extend`
@ionclude modular-scale-classes(6);

[role="main"] {
  h1 { @extend .ms-2; }
  h2 { @extend .ms-1; }
  h3 { @extend .ms-0; }
}

Ratios

Below is a list of Ratios to choose from. By default, the variable $ratio is set to $golden.

• $golden: 1.618
• $octave: 2 / 1
• $major-seventh: 15 / 8
• $minor-seventh: 16 / 9
• $major-sixth: 5 / 3
• $minor-sixth: 8 / 5
• $fifth: 3 / 2
• $fourth: 4 / 3
• $major-third: 5 / 4
• $minor-third: 6 / 5
• $major-second: 9 / 8
• $minor-second: 16 / 15

Inspiration

Sassy Modular Scale was adapted from modularscale.com by Tim Brown (@nicewebtype). Tim also wrote a supporting article at A List Apart titled "More Meaningful Typography". Additional inspiration goes to Robert Bringhurst, author of "The Elements of Typographic Style" - specifically Chapter 8 titled "Shaping the Page"
