Modular grid layout

As explained in Design for Developers

A modular grid layout is a grid-based arrangement with repeated modules organized by fixed row and column dimensions.

A modular grid layout organizes content into repeated modules using fixed row and column dimensions. It gives a page a consistent visual structure while allowing different sections to use distinct arrangements. section 6.3.2

Use a modular grid to make practical layout decisions:

  • Choose the page’s overall layout as part of its skeleton structure, considering how users read through the content. section 6.3.2
  • Vary column arrangements between sections when useful, but keep related content choices consistent—especially through the main body of text. section 6.3.2
  • Keep shared elements such as the header and footer consistent across pages, even when their body layouts differ. section 6.3.2

A modular homepage

A homepage might use four columns for one row, an asymmetrical two-column row for the next, and three columns below. Unlike a masonry layout, each module follows fixed row and height dimensions. section 6.3.2

How Design for Developers covers it

How deep it goes
Defines fixed rows and columns, contrasts masonry behavior, and gives layout-selection guidance without implementation details.
Examples
Uses multi-row layouts with four, asymmetrical two, and three columns, alongside image and card grids as related patterns.
What you can do after
Apply it to choose page skeletons, vary section columns deliberately, and preserve consistency across shared page elements.
How it connects
Connects modular grids with web layout, masonry grids, page structure, content width, and user reading patterns.
