16 per row (8 each side). 60 / 16 = 3.75 → 4 rows. Row: (18" + 24") / 12 = 3.5 ft × 4 = 14 ft. Width: (8 × 18" / 12) × 2 + 6 = 12 × 2 + 6 = 30 ft.
With two-sided seating at 10 chairs per side (20 per row), 120 guests need 6 rows. With 8 per side: 8 rows. With Chiavari chairs (16" wide, 30" row spacing), 6 rows require about 23 feet of depth. Add 8–10 feet in front for the ceremony area and 3 feet in back for the last row buffer.
| Guests | 8/Side (16/Row) | 10/Side (20/Row) | 12/Side (24/Row) |
|---|---|---|---|
| 60 | 4 rows | 3 rows | 3 rows |
| 100 | 7 rows | 5 rows | 5 rows |
| 120 | 8 rows | 6 rows | 5 rows |
| 200 | 13 rows | 10 rows | 9 rows |
A standard ceremony aisle is 5 feet wide, comfortable for one person walking with a dress train. A wide aisle (6 ft) allows father and bride side-by-side without crowding. Extra wide (8 ft) is used for grand entrances, wheelchair accessibility, or when chairs angle inward. Fire codes require minimum 4 ft.
Space between rows depends on seating style. Pews have 12" between rows (tight). Folding chairs need 24" between rows for guests to stand and sit. Chiavari chairs need 30" because they are lighter and tip easily with less clearance. Benches need 18" between rows. Measure from seat back to seat back.
Two-sided seating (bride and groom sides) is traditional and fits more guests in less depth. 120 guests in two sides of 10 need only 6 rows (23 ft deep). One side of 20 needs 6 rows too, but the seating width doubles to 27+ feet. Use one-sided for small ceremonies (under 40 guests) or non-traditional layouts.
