Layout checks
No overlaps, narrow passages or blocked door fronts were found by the layout check.

Routes to destinations were not checked. Add the venue’s entrances and destinations in Studio.
The plan assumes one 1.2 m (3.94 ft) door at the rear centre and keeps its front clear. Replace it with the venue’s actual doors in Studio.
Spacing used
- Aisle width
- 1 m
- Wall clearance
- 0.9 m
- Clear space at the front, after any reserved area
- 1.5 m
- Minimum passage width checked
- 0.9 m
- Table size
- Ø 1.5 m
- Chair size
- 0.45 m × 0.45 m
The 0.45 m row gap is legroom, not a walkway. Rows have at most 12 seats between aisles. Gaps within a furniture group are not checked as aisles.
This is a furniture layout count with the clearances you chose, not a legal occupant load. Local codes and the venue decide the permitted capacity. Exit capacity, accessible seating, evacuation, staff and other furniture are not included.
How the count is worked out
The calculator places real table and chair footprints in a rectangular room. It tries the selected pattern with its aisles and clearances, keeps furniture out of the reserved strip and door front, then checks the plan and removes groups that cause findings. Round tables may use staggered rows when more fit. This is one checked arrangement, not a proof of the maximum possible capacity.
