# dayNarrowWidth

When a day column becomes narrower than this pixel width, FullCalendar switches to "narrow" date text/layout variants.

<div class='spec'>

number of pixels

</div>

This affects responsive day text in views with day columns (such as DayGrid, TimeGrid, and MultiMonth), and is reflected by `isNarrow` in related render-hook arguments.

The default value is theme-dependent, but usually about `100` pixels.
