How Do You Customize Chrome's Vertical Tab Sidebar? (2026)

Chrome’s vertical tab sidebar has four things you can actually adjust: width, by dragging its edge; an icon-only collapsed state, toggled separately from width; native tab pinning, which behaves the same as it always has; and a set of keyboard shortcuts that mostly ignore the switch to vertical entirely. As of August 2026, on Chrome 151, none of it needs a flag.

Key takeaways

• Width and icon-only collapse are two different controls, not one setting: dragging and the collapse arrow do different things.
• Pinned tabs work the same way vertically as they always have horizontally. There’s no separate vertical-pin setting.
• Whether your Side layout choice follows you to a new device is unclear. Google hasn’t documented it, so don’t assume it does.

Resize the Sidebar to Any Width You Want

Grab the right edge of the sidebar and drag. Chrome resizes it live, with no confirmation and no relaunch. Pull it narrow enough and the titles clip down to just the favicon, which lands you at roughly the same icon-only state the collapse arrow produces, just reached by hand instead of by click. Widen it and full titles come back, wrapping to fit whatever text the page title has.

There’s a practical ceiling. Past a certain width, dragging further stops doing anything useful: the titles are already fully visible, so extra space just becomes empty margin. Chrome doesn’t publish an exact pixel range for this, and it’s not worth measuring precisely. The useful zone runs from “narrow enough to save space” to “wide enough to read every title,” and dragging by feel gets you there faster than hunting for a number.

Collapse the Sidebar to Icons Only

Separate from dragging, there’s a dedicated collapse arrow near the top of the sidebar. One click snaps the whole strip to a narrow icon rail, with no in-between state and no drag required. Click it again to restore whatever width you had before collapsing.

This is the setting to reach for if you want to toggle between “full sidebar” and “just icons” repeatedly throughout a session, since it remembers your expanded width and returns to it. Dragging is better for permanently settling on one width; the arrow is better for switching back and forth.

One related behavior to flag: auto-expand-on-hover, where a collapsed sidebar widens automatically when your cursor passes over it, is not the default in current Chrome. It exists behind chrome://flags/#vertical-tabs-expand-on-hover, confirmed present as recently as Chrome 150 in July 2026. Flagged features get pulled or changed without notice, so don’t build a workflow around it staying there.

How Pinned Tabs Behave in Vertical Mode

Pinning is not a vertical-tabs feature. Right-click any tab and choose Pin, the same option that has existed in Chrome’s horizontal strip for years, and it works identically in the sidebar — the tab shrinks to an icon-only entry and moves to the top of the list, ahead of your regular tabs.

Google hasn’t published vertical-mode-specific documentation for pinning, because there’s nothing specific to document: it’s the same underlying feature applied to a sidebar instead of a horizontal bar. If you already rely on pinned tabs for email, calendar, or a dashboard you keep open all day, switching to vertical tabs changes nothing about how they behave. They just render taller instead of wider.

Keyboard Shortcuts That Still Work (and What’s Missing)

Chrome’s standard tab shortcuts operate on the browser’s internal tab list, not on how that list is drawn, so switching to vertical mode doesn’t break them: Ctrl+Tab and Ctrl+Shift+Tab still cycle forward and back, Ctrl+1 through Ctrl+8 still jump to a specific tab position, Ctrl+9 still jumps to the last tab, and Ctrl+W still closes the active one.

What vertical mode does not add is a keyboard layer built for the sidebar itself. There’s no arrow-key navigation to move focus up and down the list, and no shortcut for the collapse arrow: you click it, or it doesn’t collapse. If you’re picturing something like typing a fragment of a title and jumping straight to that tab from the keyboard, that’s not part of the native feature. That gap gets covered below.

What Follows You to a New Profile or Device

This is the one area where the answer is “we don’t fully know.” Chrome Sync groups settings into categories (bookmarks, history, extensions, and a general “Settings” bucket), and Google does not publish which specific Appearance toggles live inside that bucket. Whether your Side layout choice reappears the first time you sign into a new machine, or whether you have to flip it again by hand, isn’t something this article can confirm without driving a second real Chrome install through a fresh sign-in.

The safer assumption: treat the vertical layout choice as local to each install until you’ve checked otherwise on your own second device. Tab groups and their colors do travel with account sync, separately from the layout setting, and that part is documented Chrome behavior rather than a guess. Pinned tabs are different again: they’re saved locally via session restore on the machine where you pinned them, and “Tabs from other devices” shows a link to that page rather than recreating the pin on the new one.

When Native Customization Hits Its Ceiling

Everything above changes how the sidebar looks. None of it changes what’s in it. Chrome’s vertical strip is still one flat list (or one grouped-by-color list) — there’s no way to save a named set of tabs, switch between two separate project contexts, or recover a set of tabs you closed two hours ago without losing everything you’ve opened since.

SuperchargeNavigation (v1.3.4) runs through the side panel API, a separate surface from the native tab strip, so the two run side by side without conflict. It adds the workspace layer Chrome’s sidebar doesn’t have, keyboard search across open tabs, bookmarks, and history via Alt+K, and automatic snapshots taken every five minutes so an accidentally closed set of tabs isn’t gone for good. Everything runs locally, no account, no telemetry.

Which Setting to Reach For

If the sidebar feels too narrow or too wide, drag the edge: that’s the only control that changes width itself. If you want to flip between full and icon-only repeatedly during the day, use the collapse arrow instead of dragging each time. If you’re moving to a new computer and want the same layout, check Settings > Appearance yourself rather than assuming Sync carried it over. And if what you actually want is named contexts for different projects or a way to search tabs by typing instead of scrolling, that’s outside what the native settings do at all — it’s what the side panel layer is for.
