Start with the clear inside dimensions, excluding steps, columns, utility equipment, and storage that cannot move. Measure a parking envelope that includes mirrors, the doors you need to open, and access around your actual car. This is larger than the vehicle's body dimensions.
Then subtract one side-wall bench. The worksheet gives leftover space, not a safety approval or a building-code clearance. Check door tracks, exits, utility access, manufacturer clearances, and your local requirements separately.
All measurements stay in this browser. The depth result is the combined space at both ends of the car; it is not available at each end. The worksheet assumes one bench along a side wall. It does not subtract a front-wall cabinet or the space you need to stand at the bench.
Run a tape-on-the-floor trial
- Tape the bench and cabinet footprints with drawers marked open.
- Park the car and open the doors you use. Walk the route carrying a typical box or workpiece.
- Roll out the tools, check the full workpiece path, then time the return to parking mode.
- Buy only after the layout works in both parked and project modes. Record what must move each time.
If the fixed bench fails, compare a mobile or fixed workbench and bench-depth choices before shopping.
