You want two windows side by side, and you have been dragging them about by hand trying to get the edges to line up.
Windows does that for you and has for years. It is one key held down and one arrow tapped, and there are three other ways in that nobody is ever shown.
I read what this machine has set for window snapping before writing, and every one of the newer options turned out to be sitting at its shipped default.
The shortcut, which is the whole article for most people
Learn this one and you will never drag a window edge again.
⭐ Microsoft documents it on its snap your windows page: "Press and hold the Windows Logo Key + Arrow to Snap the app you are on."
⚡ Left and right give you halves: Microsoft says to "Use the Left Arrow to position the app on the left side of your screen", and the right arrow for the other half.
⚠️ Up and down give you quarters. That works once a window is already at one side.
⛔ Hold the Windows key down and keep tapping. That is how you land on a quarter rather than a half.
Three other ways in
Worth knowing, because one of them suits a mouse better.
⚡ Microsoft's flyout shortcut: "press Windows key + Z" and pick a layout by number.
⭐ Or with the mouse: "Hover over the restore or maximize button of a window" and the same layouts appear.
⚠️ And the newest one: "Drag a window towards the top of the screen" to bring up the snap bar.
⛔ All four do the same job. Use whichever your hands reach for.
Snap groups, which nobody notices they have
This is the part that makes it worth doing twice, on your own machine.
⭐ Microsoft describes them: "Snap groups are collections of windows that you have snapped together", made for you automatically.
⚡ Hover any app in that group on the taskbar. The whole arrangement comes back together.
⚠️ You will see them in Task View and in Alt and Tab too, as one entry rather than several.
⛔ So snapping twice is not twice the work. Windows remembers the pair.
How do I turn snapping off?
One toggle, and it is not where you would look for it.
⚡ Microsoft's route is Settings, System, Multitasking. There, "Use the Snap windows toggle to turn Snap On or Off".
⭐ Under it sit several tick boxes for the individual behaviors, including the flyout and the snap bar.
⚠️ Turn off the ones that annoy you rather than the whole feature. Most complaints are about one of them.
⛔ This machine has snapping switched on, with every one of the newer options left unset, which is the shipped default.
What this machine reports, and what it means with three screens
Read rather than assumed, and your display count changes the answer.
⭐ Window arrangement reads as active here, and the drag-to-dock behavior is on.
⚡ There are three displays attached, one at 2560 by 1440 and two at 1920 by 1080.
⚠️ Snapping happens on the screen the window is already on. The Windows key and an arrow will not throw it to the next monitor.
⛔ Shift changes that. Which screen is which is worth settling once.
The limit Microsoft does not give you
A printed nil, because the number people ask for is not published.
⚡ We could not find a maximum number of snapped windows anywhere on that page. It describes halves, quarters and layouts and gives no ceiling.
⭐ In practice the layouts on offer depend on how wide the screen is. A very wide monitor gets three-column layouts that a laptop does not.
⚠️ Microsoft's page has a multiple monitors heading with nothing under it, so that is not documented either.
⛔ So test yours rather than trusting a number. Press Windows and Z and count what it offers.
When snapping does nothing at all
Four causes, cheapest first.
⭐ The toggle is off in Multitasking. Check that before anything else.
⚡ The window is already maximized. One arrow tap only restores it. Tap again.
⚠️ Some apps refuse to be resized, usually games and older installers.
⛔ And a remote session swallows the Windows key, so the shortcut reaches the other machine instead. Which is its own thing to configure.
Status: snapping settings and the display layout came off this machine on 29 August 2026. Every shortcut and route quoted is from Microsoft's snap your windows page. ⛔ No setting was changed, no window was moved for the sake of this page, and no app name or identifier is published.
How do I split the screen in Windows 11?
Hold the Windows key and tap the left or right arrow to send the current window to that half. Tap up or down while still holding to make it a quarter instead. Microsoft documents the same layouts behind Windows key and Z, and behind hovering the maximize button.
How do I turn snap off in Windows?
Settings, System, Multitasking, then the Snap windows toggle. Underneath it are separate tick boxes for the individual behaviors, so you can switch off just the snap bar or just the flyout rather than the whole feature.
How many windows can I snap at once?
Microsoft does not publish a number. What you are offered depends on how wide the display is, so a very wide monitor gets layouts a laptop screen never shows. Press Windows and Z on your own machine and count what appears.
Does snapping work across two monitors?
Snapping happens on the screen the window is already on, so the arrow keys will not move it to the next display. Microsoft's page has a multiple monitors heading with no detail under it. Use Shift with the arrow keys to move a window between screens first.
The Short Version
- Hold the Windows key and tap an arrow. That is the whole feature.
- Left and right give halves, then up or down turns that into a quarter.
- Windows key and Z opens the layout flyout, and hovering maximize does the same.
- Dragging a window to the top of the screen brings up the snap bar.
- Snap groups are made automatically and come back from the taskbar.
- The toggle lives in Settings, System, Multitasking, with separate ticks under it.
- Snapping happens on the screen the window is already on, not across monitors.
- Microsoft publishes no maximum number of snapped windows.
Where to Next
Try Windows and the left arrow right now, on whatever is in front of you.
Then hold the Windows key down and tap up, to see the quarter you did not know about.
Press Windows and Z once, so you know the layout picker exists.
If the snap bar at the top of the screen annoys you, switch that one tick off rather than the feature.
And if a layout appeared on your monitor that this page does not describe, tell me your screen width in the comments. The wide ones behave differently.
