Setting up a home office raises two area questions: how big is the room you have, and how big does the office need to be? The site answers them with two different calculators. The Square Footage Calculator measures an existing space — rectangle, circle, or triangle — and returns its area, with unit conversion and optional cost per square foot. The Home Office Space Calculator works the other way: it builds a required room area from desk width and depth, monitor count, storage level, and layout choice, then suggests a room length and width. Use the two together to test whether a spare bedroom, alcove, or basement corner is big enough before moving furniture.
What each calculator does
The Square Footage Calculator takes a shape and dimensions in the units you choose, converts them to a common unit, and applies the shape formula: length times width for a rectangle, π times radius squared for a circle, and base times height divided by 2 for a triangle. Perimeter is shown for rectangles, and an optional entered rate multiplies the unrounded area for a cost estimate. The page is explicit that irregular boundaries, excluded areas, measurement tolerance, and installation waste are not inferred — break complex spaces into measured shapes.
The Home Office Space Calculator converts desk width and depth from centimeters to meters and computes desk area. Work area is desk area times 1.5, storage area is desk area times 0.5 times a storage factor (1 minimal, 2 moderate, 3 extensive), monitor space is monitor count times 0.3 square meters, and circulation space is 30 percent of the base. Total space is the sum, and the layout choice — linear, L-shaped, U-shaped, or corner — derives the recommended room length and width without changing the total area.
Side-by-side comparison
| Feature | Square Footage Calculator | Home Office Space Calculator |
|---|---|---|
| Direction | Measures an existing space | Builds a required room from equipment |
| Shapes | Rectangle, circle, triangle | Desk footprint plus storage and circulation |
| Inputs | Dimensions and units | Desk width/depth, monitors, storage, layout |
| Outputs | Area (and rectangle perimeter, optional cost) | Total area plus recommended length and width |
| Units | Multiple, converted before formula | Centimeters to meters, square meters output |
| Assumptions | None inferred — measure complex spaces | 1.5× work area, storage factors, 0.3 m² per monitor, 30% circulation |
When to use which
Use the Square Footage Calculator first when the room already exists: measure the spare bedroom or basement corner to get the area you have to work with. It is also the general tool for any other room-area question, and its own page points to material calculators such as tile, concrete, paint, and mulch once the area is known.
Use the Home Office Space Calculator to define the requirement: whether a 120 cm by 60 cm desk fits comfortably, what a second monitor implies, and whether an L-shaped layout needs different proportions than a linear wall desk. Then compare its square-meter result with the measured room area, and check real-world clearances — chair pull-back, door swing, drawers, monitor depth, glare, cables, and ventilation — that the estimate deliberately does not cover.
For the height of the workstation inside the room, the office page also points to the desk height and desk ergonomics calculators, and for furniture budgeting, the home office setup cost calculator.
