If you are planning a workshop, a board meeting, a training session or a ceremony in a Chicago-area meeting room, church hall or conference space, the first decision is the room style. The same room can seat almost twice as many people in theater style as in classroom style, and neither is wrong. It depends on what your attendees need to do: listen, write, eat or move.

Same room, two layouts

Theater packs chairs in rows; classroom adds a table in front of every row of chairs.

Side by side

Factor	Theater	Classroom
Square feet per person	8 to 10	14 to 18
Capacity of a 30 x 40 ft room (1,200 sq ft)	About 120 to 150	About 65 to 85
Writing surface	None	Yes
Row spacing	32 to 36 in back to back	5 to 6 ft front to back
Best for	Ceremonies, talks, performances	Training, workshops, exams
Table rentals	None	6 ft x 18 in (or 24 in) training tables
Chair count	One per person	One per person

These are rules of thumb. Fire and building codes set legal capacities, so confirm the number with the venue.

Row spacing and aisles

For theater seating, set rows 32 to 36 inches back to back, with chairs linked or aligned. Leave a center aisle of 5 to 6 feet and side aisles of 3 to 4 feet. No seat should be more than a few seats from an aisle: a block of 10 to 14 chairs between aisles is typical. For a ceremony, see wedding ceremony floor plan and aisle width.

For classroom seating, tables are usually 6 feet long and 18 or 24 inches deep, with two or three chairs per table. Leave 5 to 6 feet between the front edge of one row of tables and the back of the next row's chairs, so people can sit and stand. Leave aisles of 4 feet on each side.

Other styles worth knowing

Style	Square feet per person	Use
Theater	8 to 10	Ceremonies, lectures, performances
Chevron or herringbone	10 to 12	Training with a focus on the front
Classroom	14 to 18	Workshops, note-taking
Banquet rounds	10 to 15	Meals, galas; see square feet per guest
Conference or U-shape	20 to 30	Meetings, discussions

For events with dinner, see floor plan for 100 guests.

Screens, stages and sightlines

A projector screen should be roughly one-sixth of the distance to the back row in height, a standard rule of thumb for presentations, so a 60-foot-deep room wants a tall screen. The first row should sit at least 1.5 to 2 times the screen height away. Place the screen at the narrow end of the room to keep the audience closer. See projector and screen size for events and sound system for speeches.

Accessibility

Reserve wheelchair spaces in both styles, spread across rows with companion seats next to each, and keep a 36-inch minimum path to them. In classroom style, leave a table without a chair in the first or second row. See ADA accessible event seating and pathways. Reserved rows for VIPs are covered in reserved seating and signage layout.

Chicago-area meeting rooms

Hotels, libraries and park district rooms around Chicago often include tables and stackable chairs. Ask what is included, how many are available and how long the room takes to turn. If your event needs more chairs, rent a matching set rather than mixing; stackable styles like the garden folding chair or the shell chair work well for conferences. See shell chairs for corporate events and stackable vs non-stackable chairs.
