About this calculator
Planning estimate for the clear space from the sofa, across an assumed 18-inch sofa-to-table gap and coffee table, to the opposite wall. Furniture dimensions and a 36-inch walkway are planning assumptions; this tool does not size a TV console.
Worked example
calculated with the default values below
Room length 16 ft · Sofa depth 36 in · Coffee table depth 24 in Clearance beyond the coffee table 114 in · Leaves a 36 in traffic lane? Yes

This record describes the implementation used by this page. It is not independent validation. External references, when available, support only the stated formula or definition; estimates and custom rules retain their own assumptions.
Formula and variables
g = roomLength × 12 − sofaDepth − 18 − coffeeTableDepth; walkway = g ≥ 36
- roomLength
- room length (ft)
- sofaDepth
- sofa depth (in)
- coffeeTableDepth
- coffee-table depth (in)
- g
- table-to-TV gap (in)
Remaining clearance = room length in inches − sofa depth − assumed 18-inch gap − coffee-table depth. A 36-inch walkway is a planning threshold; no console width is calculated.
Frequently asked questions
How is the remaining walkway estimated?
The model subtracts sofa depth, an assumed 18-inch sofa-to-table gap and coffee-table depth from room length. It flags less than 36 inches of remaining clearance as tight. Measure your own layout; it does not recommend a TV-console width.
