How big should your home office be? Size the desk from your monitors, check the chair zone, lay out the full room, plan meeting space, storage, lighting and acoustic treatment — 7 modes in one free tool.
Pick your monitors and extras. The tool computes the minimum desk width (floored at 48 in) and depth (floored at 24 in) and recommends the nearest stock desk size.
The chair needs a 36-inch zone behind the desk to pull out and stand up. This computes the minimum room depth for your desk.
Add up everything the room must hold — desk, chair zone, storage and visitors — plus a 15% circulation buffer, to get the minimum room size.
Planning allowance: 15 sq ft per visitor (chair plus personal movement). Check whether your free floor area fits the meeting.
Enter how many of each storage unit you need. The tool totals the floor footprint and the continuous wall length required.
Office guidance: 300 lux for screen-based work, 500 lux for document work, 750 lux for detailed work. Total lumens = lux x area.
Treat 15-20% of the wall-plus-ceiling surface for a home office, and verify the setup against the 20-30 in viewing-distance rule.
Exact physical width, height and diagonal of any monitor — for desk spacing math.
Convert lumens, lux, watts and efficacy between bulb types for your office.
Check the actual illuminance your office lighting delivers on the desk.
