Watch anyone with a big monitor work and you will see the same dance: drag window here, resize it, drag the next one, nudge the edge until it lines up, lose the whole arrangement when a window gets maximized by accident. Most people spend minutes a day arranging windows with mouse precision they do not actually have.
Window managers fix this by making windows snap to sensible layouts. Windows has gotten genuinely good at this natively, and third-party tools add the depth the built-ins lack. Here are four options, from the one already on your machine to the tool that treats your desktop like a custom grid.
Snap Layouts: the built-in that most people never find
Since Windows 11, hovering over the maximize button on any window pops up Snap Layouts: little diagrams for side-by-side, quadrants, thirds, and more. Click one and your windows snap into that arrangement. Drag a window to the screen edge and Windows offers to snap it too.
The strengths:
- Already installed, zero setup, works in every app
- Quick enough that it covers many people's entire needs
- Pairs with snap groups, so an arrangement survives minimizing and taskbar switches
The trade-offs: layouts are fixed presets; you cannot define your own zones or control margins. And many people have never discovered the feature, because hovering the maximize button is not something anyone does by instinct. Before installing anything, try this. If side-by-side and quadrants cover you, you are done.
PowerToys FancyZones: your own grid, your rules
FancyZones is part of Microsoft's free PowerToys collection, and it is the step up from Snap Layouts. You design your own zone layouts: a column for your editor, a wide zone for the browser, a narrow strip for chat, with custom gaps and monitors each getting their own layout. Hold a modifier key while dragging a window and it snaps into whichever zone you drop it on.
The strengths:
- Fully custom layouts per monitor, including unusual monitor setups
- Overrides Windows' snap behavior with your zones
- Free, open source, straight from Microsoft
The trade-offs: it is a tool you configure, and the layout editor has a learning curve measured in half an hour, not seconds. FancyZones also replaces rather than extends normal window dragging, and the first week involves moments of "why did it snap there?" Power users love it; casual users may find they never venture past the presets that Snap Layouts already offers.
AquaSnap: window management with manners
AquaSnap from Nurgo Software takes a different approach: instead of grids, it makes normal window dragging smarter. Drag a window to an edge and it snaps; drag a window by any edge, not just the title bar, with a modifier held; shake one window to make it transparent; snap two windows' edges together and they dock, moving as a pair.
The strengths:
- Small, fast, and works with your existing habits rather than replacing them
- Window docking, tiling of multiple windows in one drag, and window transparency
- Free for personal use, with a paid Pro tier for the advanced features
The trade-offs: it does not impose layouts, so if your problem is "I want a perfect three-column grid," AquaSnap is not that tool. Some of the best features are gated behind Pro. And its many subtle gestures, like window shaking and edge dragging, are the kind of thing you forget exist until you re-read the feature list.
DisplayFusion: for multi-monitor people
DisplayFusion is broader than a window manager: it manages monitors, wallpapers, taskbars, and profiles, and window management is one part of a larger toolkit. Its window position rules let you define where specific apps open, and its monitor profiles switch your whole setup when a display configuration changes, which matters if you dock and undock a laptop.
The strengths:
- Built for multi-monitor life: per-monitor taskbars, monitor profiles, window position memory
- Powerful window snapping and hotkeys for moving windows between monitors
- A free version covers basics; a one-time Pro license unlocks the rest
The trade-offs: it is the heaviest option here, both in features and in how much there is to learn. If you have a single monitor, most of its value evaporates. The interface feels like a settings panel from an earlier era, dense with tabs, and the free version is really a demonstration of the Pro one.
Which one should you pick?
- Not aware you need this yet: try Snap Layouts first, seriously
- Want custom grids and live in a few fixed apps: FancyZones
- Want windows to behave better without changing habits: AquaSnap
- Two or more monitors and a docked laptop: DisplayFusion
The honest progression is built-ins, then one third-party tool, and only then a second. Start with what is free and already installed; upgrade only when you can name the thing it fails to do.
