Desk-space calculator

Estimate the desk surface your equipment needs before comparing products. Enter the maximum space in your room—not the size of a desk you have already found.

Your available space

Maximum width (cm)Maximum depth (cm)External monitors

Keep an open laptop beside the screen Leave room for notes or paperwork

How this estimate works: the calculator uses practical starting allowances for laptop-only, single-monitor and dual-monitor layouts. It is a planning aid, not a guarantee of product fit. Measure the exact equipment, monitor stand or arm, wall clearance and chair movement before ordering.

Desk-size reference

What common desk dimensions can hold

The examples below apply the same allowances as the calculator. They are layout starting points, not claims that every product with those dimensions will fit.

Desktop	Useful starting scenario	Main constraint to check
80 × 50 cm	Laptop-only work with compact input devices	Forearm support, chair access and cable space
100 × 60 cm	One external monitor without a side-by-side open laptop	Monitor-stand depth and eye distance
120 × 70 cm	Two monitors, or one monitor plus an open laptop	Combined screen width and stand footprint
140 × 70 cm	Two monitors with useful writing or docking space	Room and chair pull-out footprint

Measure the equipment

Use physical monitor width, stand depth, keyboard depth and the cable bend—not only the product category.

Calculate screen dimensions

Measure under the desk

Drawers, frames and cable trays can reduce knee, thigh and chair-arm clearance even on a wide top.

Use the measurement worksheet

Measure the room

Include the chair pulled back, open doors, radiators, skirting boards and a usable walking route.
