+ MEASURE TWICE. UPGRADE ONCE.
Desk layout planner.
Find your fit.
Before you buy the new monitor, give it a place to land. Compare three layouts on the desk you actually own.
Make room for the upgrade.
A footprint check, not a fitting guarantee. Use the largest top-down footprint that matters, including the stand or screen overhang. This model does not assess ergonomics, arm compatibility, structural strength or load capacity.

Unoccupied space is one part of the decision.
A layout still needs to work for you.
Surface area uses the union of footprints inside the desk: overlapping areas count once, and anything hanging outside is excluded. “Fits” means no overlaps and no footprints outside the desktop. It does not mean comfortable, safe or structurally supported.

Illustrative measurements, not product specifications. Loading an example replaces the current plan on this device.
The tape measure
still gets the last word.
Screen diagonals do not tell you how much desk a setup uses. Start with the physical footprint, leave the spaces you actually need, and compare before committing.
What should I enter for the monitor?
Enter the width and depth of a rectangle covering the monitor and its stand as viewed from above. A screen can extend past its stand. If that overhang matters to your space, include it. This simplified model treats the entire rectangle as occupied.
How should I measure mouse space?
Use your mouse mat dimensions, or measure the clear area you want for movement. That rectangle is reserved, even though the mouse itself is smaller. It should not overlap your keyboard or monitor footprint.
What does “unoccupied” actually mean?
It is the desk area not covered by any of the three modeled rectangles. Two overlapping objects count once in this calculation, but their overlap still produces a conflict. Unoccupied patches are not necessarily contiguous or useful. This number is not a comfort score.
Can I save or share my layouts?
Changes are saved in this browser when local storage is available. A share link contains all three layouts and their names. Anyone with the link can read and modify their own copy. Download gives you a dimensioned SVG image of the comparison.
What is outside the scope of this tool?
Monitor arm mounting, desk construction, weight limits, viewing distance, cable reach, wall clearance and ergonomics require separate checks. A green result only means the rectangles fit on the modeled surface without overlapping.
