Tailwind CSS Width

The tailwind width utility classes allow you to easily control the width of elements in your web applications.

Tailwind Width

Tailwind gives you a w-* utility that sets an element’s width directly in the class name. You can use fixed sizes, percentages, fractions, or even custom values without writing CSS.

How to set Tailwind Width

Use w-{size} to set an element’s width. That size can come from Tailwind’s spacing scale (w-64), a fraction of its parent (w-1/2, w-3/4), or a percentage using arbitrary values (w-[25%]).

html
<div class="w-12">
	<div class="w-14...">w-14</div>
	<div class="w-16 ">w-16</div>
	<div class="w-32">w-32</div>
</div>

Different Ways to Set Tailwind Widths

Fixed Widths

To apply a fixed width to an element, you can use classes like w-px, w-1, w-4, w-8, etc. Each of these classes corresponds to a specific width in pixels, calculated based on the root font size (by default, 1rem is equal to 16px).

html
<div class="flex...">
	<div class="w-20...">w-20</div>
	<div class="w-32...">w-32</div>
	<div class="w-40...">w-40</div>
	<div class="w-60...">w-60</div>
	<div class="w-80...">w-80</div>
	<div class="w-96...">w-96</div>
</div>

Fractional Tailwind Widths (Percentages)

Fractional widths like w-1/2 or w-3/4 are handy when you want elements to scale with their container, like splitting a card grid evenly.

html
<div class="bg-green-500 w-full">w-full</div>
<div class="flex...">
	<div class=" bg-green-500  w-4/5">w-4/5</div>
	<div class=" bg-green-500  w-1/6">w-1/2</div>
</div>
<div class="flex...">
	<div class=" bg-green-500  w-4/5">w-4/5</div>
	<div class=" bg-green-500  w-1/5">w-1/5</div>
</div>
<div class="flex...">
	<div class=" bg-green-500 w-3/4">w-3/4</div>
	<div class=" bg-green-500 w-1/4">w-1/4</div>
</div>
<div class="flex...">
	<div class=" bg-green-500  w-2/3">w-2/3</div>
	<div class=" bg-green-500  w-1/3">w-1/3</div>
</div>
<div class="flex...">
	<div class=" bg-green-500 w-1/2">w-1/2</div>

Tailwind ViewPoint Width

When you want a section to span the entire screen width, viewport units are your friend. Tailwind exposes this with w-screen.

html
<div class="w-full bg-green-600 p-4 rounded">
	<h1 class="text-center text-white">Showing the w-screen</h1>
</div>

Preview

Showing the w-screen

Arbitrary Values

Sometimes the spacing scale isn’t enough. Arbitrary values let you set exact widths without touching your config: w-[420px], w-[35%], w-[min(80vw,600px)].

html
<div class="p-4 rounded-t-xl bg-green-100">
	<div class="flex-col space-y-4 text-center text-white font-bold">
		<div class="w-[420px] bg-green-600 p-3 rounded">Exact width in pixels</div>
		<div class="w-[35%] bg-green-600 p-3 rounded">
			Width based on parent percentage
		</div>
		<div class="w-[min(80vw,600px)] bg-green-600 p-3 rounded">
			Clamp-like behavior
		</div>
	</div>
</div>

Hover and Focus Interactions with Width

You can animate width changes on interaction. Keep it subtle so layouts don’t jump.

html
<div class="p-4 rounded-t-xl bg-green-100 flex justify-center items-center">
	<a
		class="w-24 hover:w-36 transition-all duration-300 inline-block bg-green-600 text-white font-bold text-center p-2 rounded-md"
	>
		Hover me
	</a>
</div>

Preview

Hover me

Tip: If width changes cause layout shifts, consider transform-based animations on a child element instead.

Responsive Tailwind Width

Tailwind is mobile-first. Add breakpoint prefixes to change width at different sizes: sm:, md:, lg:, xl:, 2xl:.

html
<div class="w-full md:w-1/2 lg:w-1/4">
	Full width on mobile, half width on medium screens, and quarter width on large
	screens
</div>

Preview

Full width on mobile, half width on medium screens, and quarter width on large screens

This avoids custom media queries and scales cleanly as the viewport grows.

Customizing Tailwind Width

If certain widths show up a lot in your design system, add named tokens in tailwind.config.js. Which could be w-card, w-sidebar, etc., which reads better in code reviews.

js
// tailwind.config.js
module.exports = {
	theme: {
		extend: {
			width: {
				card: "26rem",
				profile: "18rem",
				sidebar: "20rem",
			},
		},
	},
};
html
<div class="p-4 rounded-t-xl bg-green-100">
	<div class="flex-col space-y-4 text-center text-white font-bold">
		<div class="w-card bg-green-600 p-4 rounded">Custome-A</div>
		<div class="w-sidebar bg-green-600 p-4 rounded">Custom B</div>
	</div>
</div>

Why this pattern works: the grid controls column count per breakpoint; w-80 keeps each card consistent, so heights and content don’t cause the layout to wobble.

💬Modal Dialog

Combine viewport width with a max-w-* cap so the dialog feels roomy on mobile and tidy on desktop.

Modal content

Call to Action Button

Let the text define the width naturally with w-fit. This avoids huge buttons on desktop.

Best practices

  • Start with the spacing scale before reaching for arbitrary values. It keeps your UI consistent.

  • Pair w-* with max-w-* to stop content from stretching too wide on large screens.

  • Don’t forget spacing (p-, m-). Width alone can make components feel cramped.

  • w-fit is great for chips, tags, and buttons where content drives the size.

  • If you reuse a size, add a named token in tailwind.config.js (w-card, w-sidebar) for readability.

Accessibility and layout integrity

  • For long-form content, cap line length with max-w-prose.

  • Prevent horizontal scroll with w-full + overflow-x-auto on containers that hold wide content (tables, code blocks).

  • Be careful with w-screen on mobile—safe areas and scrollbars can introduce overflow.

  • If you animate width on hover, test it with keyboard focus too.

Common pitfalls (and how to avoid them)

  • Large fixed widths (w-96, w-[400px]) can break small screens → add responsive overrides or a max-w-*.

  • w-screen without scroll containment can cause unintended horizontal scrolling.

  • Width changes on hover without transitions look jumpy → add transition-all duration-300.

  • Forgetting a base width (w-full) can cause columns to collapse on mobile.
