One column

Everything in a single column, read from top to bottom. Gives one reading order with nothing to choose between, at every width.

Good for: Articles, forms, plain services, pages read on phones.

Weak for: Ranges people compare side by side; wide screens look empty.

The same at every width: only the line length and the margins change. Keep lines under about 75 characters on wide screens.

Parts that show it

How it is found

In a wireframe: A section, outside the header and footer, with no split, no grid of two or more columns and no swipe row. A page type when most of its sections are like that.

On a real page: At 1280 px, less than a sixth of the text sits beside something else, and no split, card grid or sidebar was found.
