A session on handling disease in whiteleg shrimp is about to start. The small hall has been filled with three hundred chairs in long rows. The speaker opens slides on how to read PCR results and plans an exercise with a test kit. The farmer sits in row fifteen, with no table, no way to write and no way to see the small print on the screen.
Chair layout sounds minor, but it decides whether the session teaches anything. This article covers seminar room setup per the CEM guides, with the standard distances and how to match a layout to each kind of session at an aquaculture trade show.
Choose the layout by the goal of the session
The CEM guides lay down a principle: the room setup should match the objectives of the meeting. The factors to weigh include program and learning objectives, formal or informal presentation, expected interaction, attendee safety, audiovisual needs, room for screens, staging and seating, entry and exit flow, and where restrooms and refreshments are. The room must be measured accurately before anything is laid out.
At an aquaculture show, five kinds of session come up often. Each suits a different layout.
- A long talk for many farmers (market trends, general technique): theater.
- A training session over two hours with notes and handouts (pond water management, reading test results): classroom.
- Group practice and case exercises: crescent round.
- A closed meeting between buyers and suppliers, or a working group: boardroom or U-shape.
- An open discussion among many people: hollow circle.
Theater: rows of chairs, no tables
The guides describe theater as chairs set in rows facing the stage, with no tables. The limits are difficult note taking, blocked sight lines from the back and little room for personal items. Guidelines worth remembering:
- The first row sits at least 1.8 m from the edge of the stage, or two times the screen height, whichever is further.
- No more than 14 chairs in a row in the center section.
- Side sections are set at an angle, chevron style, for a more direct line to the speaker and screen.
- Two side aisles at least 1.2 m wide. A section over 10 rows adds 61 cm, making 1.8 m. A section over 30 rows needs 2.4 m aisles.
- Space between rows at least 61 cm from the back of one row to the front of the next. The best viewing angle to the speaker or screen is 45 degrees or more, and never less than 22 degrees.
The guides add that local fire codes can set row lengths, the number of rows in a section and aisle widths, so the organizer must learn the rules of the actual venue.
Classroom: tables and chairs facing front
Classroom gives each person a table and suits sessions longer than two hours that need notes, especially with larger groups. The guides give these measurements:
- The first table row at least 1.8 m from the stage, or two times the screen height.
- Tables at least 46 cm wide, usually 1.8 m or 2.4 m long.
- Each person needs at least 80 cm of table length. A 1.8 m table seats three and a 2.4 m table seats four.
- If learners bring laptops or binders, allow 80 to 90 cm each, which means at most two at a 1.8 m table and three at a 2.4 m table.
- Space between rows at least 61 cm from the back of one chair to the front of the next. Aisles follow the theater rules.
One drawback to know: a large room set to its maximum cuts interaction, and people at the back struggle to hear and see. For a rapid-test class or a session on reading PCR results, prefer a medium room and do not fill every seat.
Crescent round, U-shape and the small formats
Crescent round uses round tables of 152, 168 or 183 cm diameter, with people occupying about two thirds to three quarters of the table, facing the speaker. Each table seats 5, 6 or 7 people. Leave at least 1.5 m between tables. It takes more floor than classroom, but suits group practice and switches from a meal to working very quickly.
For groups of 5 to 32, the guides list boardroom (rectangular or oval table with chairs on all sides), hollow square, hollow circle, T-shape and U-shape. They create a sense of unity and a formal feel, and suit problem solving or a meeting with a facilitator. That makes them the right home for small-group matchmaking sessions.
Screens, sight and sound
The CEM guides give a few rules of thumb for screens. The top edge sits at least 30 cm below the ceiling and the bottom edge at least 1.2 m above the floor. The screen width is at least one sixth of the distance to the last row. The first row sits about two screen heights away. The audiovisual contractor is the best source for the right screen size, so invite them to survey the room.
The guides add factors for adult learners: good sight lines from everywhere, enough personal space, enough writing room, cultural considerations, special needs such as wheelchairs or interpretation, and enough exits for safety with little disturbance. If Vietnamese-English interpretation is planned, there must be room for the equipment and the interpreters, something that is rarely thought of while placing chairs. Topic selection is covered in the article on technical seminars at an aquaculture show, and adult learning theory in the article on andragogy.
Need seminar rooms designed for an aquaculture show?
If you need layout drawings for each type of session, a capacity table for each seating style or help working with the audiovisual contractor, you can send a request through the quote page or book a call with Nguyen Anh Trung. Send the room plan and the draft list of sessions so the call starts from specifics.
A session with two hundred seats where only the front row can see is more disappointing than a small room that is full.
