Workspace planning
Work out how much desk width you need for one or two monitors placed directly next to each other, with no overhang.
Required desk width
—
Still needed: monitor 1 outside width, left margin, and right margin.
Width check only: this result does not assess desk depth, monitor stand footprints, load capacity, or monitor arm compatibility.
Measure each monitor across its widest outside edges, including the bezel. The result adds those widths to your chosen gap and side margins. It assumes the monitors sit in a straight line and remain fully above the desk surface.
This is a width check only. It does not assess desk depth, load capacity, monitor stand footprints, or whether a monitor arm can safely support or position your screens. The Monitor arm compatibility checker compares a monitor arm's published weight, VESA, and mount figures with the screens and desk.

The guides that cover what this calculator leaves out: desk depth, monitor arms, and which desk to pick.
Makers lead with how high a standing desk goes. In a spare bedroom the numbers that decide it are how low it comes down, how deep the top is and how wide your monitors are. Ten desks compared on those three, with a pick for a narrow room, a shorter person, a tight budget and an app.
A light monitor can be too light for a gas spring arm, and a flat-pack top has its own limit for a clamp's concentrated load. Ergotron, HUANUO and VIVO arms against Dell panel weights and IKEA tabletop limits, with a pick for a solid desk, a light panel, an ultrawide and a flat-pack top.
