Computer Classroom Design Criteria

Workstation Size

• 30" wide computer stations fit full-width keyboards and mousing surfaces (left/right). SMARTdesks keyboard trays are 28" wide.
• Allow 42" between rows (with keyboard retracted) when using computer task chairs on casters (39" for task chair with thin PVC back).
• Position CRT/LCD with 30" from user eye to screen.
• Allow 30"d surface for 14-19" CRT, 36" for 21" CRT.
• LCD displays reduce desk depth requirement by 4-6".
• Allow 72" deep x 60" wide space (minimum) for instructor station (desk or lectern). Include adequate access (check ADA requirement).
• TIP: If students must access their stations by passing behind instructor's desk, allow minimum of 96" depth plus 36" to the side.

   Aisle Width

• Establish 36" minimum width for aisles between rows of desks. 42" is preferable for wheelchair access.
• Staggering desk rows increase perceived and actual aisle width and access.
• For wheelchair access, maintain 48" minimum width for aisles to doors and 30" turning radius.
• TIP: It is usually easier and less costly to move a door (and always simpler to change a door's swing) than to design around it.
• Allow 30" chair space between laptop table rows.
• If possible, allow 60" between conference table edge with keyboard trays retracted and wall.

   Equipment and Storage

• Printer carts, cabinets or tables should offer enough width for printer and standard paper tray side-by-side.
• Be sure to include accommodations for in-room media and supplies storage requirements.
• TIP: Locate single printer near the instructor or entrance door to facilitate distribution and access.
• Suspend projectors and screens from ceiling or walls to protect from damage and vibration, ensure correct positioning and save floor space.

  Doors, Windows, Radiators, Columns

• Hold desks 6" from radiators and air ducts for adequate circulation.
• Desks should run parallel to windows to prevent glare.
• Be sure to account for door swing.
• TIP: It is usually easier and less costly to move a door (and always simpler to change a door's swing) than to design around it.
• Columns may affect visibility as well as seating. When planning, be sure to note location and size.

   Seating

• Adjustable computer chairs with arm rests promote ergonomic seating position resulting in increased classroom productivity and cognitive retention.
• Be sure tablet arms are large enough to support laptops and swing up and out of the way to permit easy access.
• 7-10% of tablet arm chairs for classrooms should be specified as left-handed.
