How to Plan and Preview a Multi-Monitor Layout with Multi-Monitor Calculator

You can plan a multi-monitor layout on multimonitorcalculator.com by adding monitors to a workspace, dragging them into the arrangement you want, adjusting the available desk width and height so the layout reflects your real space, then saving the setup and generating a shareable link. This works best as a planning step before you buy monitors or mounts, or when you want to test whether a proposed arrangement physically fits your desk.

Getting started

The site describes itself as a tool for planning a multi-monitor setup, with features for calculating PPI and other screen calculations, previewing custom desktop wallpapers, dragging and rearranging monitors, and searching for monitors. The planning workflow below uses the layout controls shown on the site.

Before you start, have these ready:

• The screen sizes and resolutions of the monitors you plan to use (or are considering buying).
• The physical width and depth of your desk, so you can set realistic limits.
• A rough idea of the arrangement you want: side-by-side, stacked, angled, portrait plus landscape, and so on.

Step-by-step: build and preview a layout

1. Add monitors

Use Add Another Monitor to place each screen in the workspace. Add one monitor at a time until the count matches your planned setup. If you are starting from an existing example, you can instead open one of the prebuilt community submissions (for example, "Dev Command Center," "Video Editor's Dream," or "6 Monitor Engineering Workstation") and modify it.

2. Drag and rearrange monitors

Drag monitors within the workspace to try different layouts. The site's stated purpose is to let you "drag and rearrange monitors to try out different layouts," so use this step to test:

• Whether a center monitor plus two angled side monitors leaves enough room.
• Whether a stacked pair fits above your main screen.
• Whether a portrait monitor beside a landscape one creates awkward gaps.

3. Set your available desk width and height

Use Increase Available Desk Width / Decrease Available Desk Width and Increase Available Desk Height / Decrease Available Desk Height to match your real desk. The workspace then shows whether your arrangement fits within that space. This is the step that turns a pretty picture into a practical check: if the layout spills past your desk dimensions, you know to resize screens, change angles, or reconsider the plan.

4. Preview wallpapers across the arrangement

The site supports previewing custom desktop wallpapers across a multi-monitor arrangement. Use this to check how an image spans your screens, where the bezels will cut through it, and whether the composition still works once split across monitors of different sizes or orientations.

5. Save, share, and revisit

• Generate Link creates a link to your setup that you can send to friends or open on other devices. The site confirms with "URL Copied to Clipboard!" when the link is generated.
• Submit Setup lets you submit your layout as a community submission, with a setup name, description, and a note on what makes it unique. The site states submissions may be featured as prebuilt setups.
• Reset returns the workspace to the default setup. The site warns that all progress will be lost, so generate a link first if you want to keep your work.

Verify your plan before committing

After arranging monitors, confirm these points:

Common sticking points

• Resetting by accident. Reset wipes the workspace. Generate a link before experimenting with a fresh layout, or use the + button in the top navigation bar to create a new setup instead of resetting.
• Unrealistic desk dimensions. If the desk width and height don't match your actual furniture, the fit check is meaningless. Measure first, then adjust.
• Forgetting the physical mounts. The calculator plans screen positions, not arm or stand clearance. Check that your monitor arms can actually reach the positions you've drawn.
• Skipping the wallpaper preview. A layout can look fine as rectangles but fail once an image spans it. Preview before you finalize.

Once your layout fits your desk, shares correctly, and looks right with a wallpaper preview, you have a plan you can use to buy monitors, position mounts, and set up your actual desk with fewer surprises.
