How to Design a Conference Room
A step-by-step guide to designing a professional conference room — from room assessment to equipment selection, compliance, and deployment.

Start With the Room, Not the Equipment
The most common mistake in conference room design is starting with equipment selection. Professional AV design starts with the room itself — its dimensions, its purpose, its seating layout, and the furthest viewer. Every equipment decision flows from these fundamentals.
Step 1: Assess the Room
Measure the room's length, width, and ceiling height. These three dimensions determine everything that follows — display size, camera coverage, microphone placement, and acoustic treatment. The furthest viewer distance (from the farthest seat to the display wall) is the single most important measurement.
Room Assessment Workflow
Measure L×W×H
Identify furthest viewer
Determine seating capacity
Select platform (Teams/Zoom)
Step 2: Size the Display (AVIXA DISCAS)
Display sizing is governed by AVIXA's DISCAS standard. For general meeting content (slides, video), use the Basic Decision Making (BDM) formula: display diagonal ≥ furthest viewer distance ÷ 4. For detailed content (spreadsheets, CAD), use Critical Confident Monitoring (CCM): diagonal ≥ distance ÷ 3.
| Room Length | Furthest Viewer | BDM Minimum | CCM Minimum |
|---|---|---|---|
| 12 ft | 10 ft | 30" | 40" |
| 16 ft | 14 ft | 42" | 56" |
| 20 ft | 18 ft | 55" | 72" |
| 24 ft | 22 ft | 66" | 88" |
| 30 ft | 28 ft | 84" | 112" |
TotalSyncAV's room configurator calculates this automatically — enter your dimensions and the engine returns the minimum compliant display size, recommended commercial models, and the compliance score.
Step 3: Select the Camera
Camera selection depends on room size and platform. For huddle rooms (2–4 people), a wide-angle USB camera suffices. For small and medium rooms, you need intelligent auto-framing. For large rooms, multi-camera with PTZ tracking is required.
Camera Selection Checklist
- ✓Wide-angle (90°+) for huddle rooms
- ✓Auto-framing with person detection for small/medium rooms
- ✓Multi-camera PTZ with tracking for large rooms
- ✓Platform-certified (Teams or Zoom certification)
- ✓Minimum 1080p at 30fps
Step 4: Plan Audio Coverage
Audio is where most rooms fail. The microphone must cover the entire seating area with full-duplex echo cancellation. Tabletop speakerphones work for huddle rooms, but medium and large rooms require ceiling-mounted beamforming microphone arrays.
| Room Size | Mic Type | Coverage Radius | Example |
|---|---|---|---|
| Huddle (2–4) | Integrated speakerphone | 6 ft | Shure Stem One |
| Small (4–6) | Ceiling array or soundbar | 10 ft | Shure MXA710 |
| Medium (7–12) | Ceiling beamforming | 20 ft | Shure MXA920 |
| Large (13+) | Distributed ceiling mics | 30 ft+ | Shure MXA910 ×2 |
Step 5: Check Compliance
Before finalizing the design, run a compliance check. Every room must meet AVIXA DISCAS for display sizing, ADA for mounting heights and accessibility, and platform-specific certification requirements. TotalSyncAV automates this entire check — the compliance engine returns a score (0–100) with specific gaps and remediation steps.
Pre-Deployment Compliance Checklist
- ✓Display sized to AVIXA DISCAS for furthest viewer
- ✓Display bottom edge ≥ 42" AFF (ADA)
- ✓Camera provides full-room framing
- ✓Microphone covers entire seating area
- ✓Network: dedicated VLAN with QoS
- ✓Acoustic treatment for RT60 ≤ 0.6s
Automate the Entire Process
Every step above — room assessment, DISCAS calculation, equipment selection, compliance checking — is automated by TotalSyncAV. The room configurator takes dimensions and platform, returns a complete compliant design with BOM, and the AI Design Audit validates existing rooms from a single photo.
