If the screen size is wrong, the meeting experience will be directly discounted. A small conference room with 4-6 people is equipped with an 86-inch screen, which is too close to the screen and has obvious pressure on the wall. The 12-person conference room uses a 55-inch screen, and remote participants cannot see Excel and PPT small print. Although the 75-inch screen is suitable for most conference rooms, if the room is deep and complex, 86 inches may still be required. Enterprises only purchase according to the number of meetings, but ignore the layout of tables and chairs, the farthest seats and the actual content.

The size of the interactive whiteboard in the meeting room can not only look at the number of meetings, but also the room area. The maximum viewing distance and the minimum content that must be seen clearly in the meeting are the key to determining whether 55, 75 or 86 inches. Professional meeting room selection is usually recommended to consider the room size, viewing distance, number of participants, furniture layout, wall space, power and network location, and the actual use of the meeting.

1. measuring meeting room before selecting size

Six data that must be mastered before purchasing

1. The farthest viewing distance

• Measured from the screen surface to the farthest normal seat
• Don't just measure the length of the room.
• Record the first row, last row and side seats
• Confirm whether all participants can see the small font
• If the meeting room is a strip, the viewing distance is preferred over the area

Number of meetings

2-4 people, 5-8 people, 8-12 people, 12-20 people, more than 20 people. The number of people can help determine the type of meeting room, but it is not a substitute for distance measurement.

3. Seating Layout

Face-to-face conference table, U-shaped conference table, classroom-type training layout, theater seating, group island layout, movable desk. Different seat layouts will change the viewing angle and distance of some participants.

4. Content Type

Text and contracts, PPT, Excel and data boards, product prototypes, CAD/BIM drawings, video conferencing, remote expert screens, multi-window collaboration. The finer the content, the larger the screen size required.

5. Wall and Installation Conditions

Available wall width and height, wall load bearing, wall mount or mobile bracket, screen center height, camera mounting position, cable path, socket and network interface.

6. Handling route

Door opening, elevator, corridor, corner, packaging size, site unpacking position, large screen maintenance and replacement channel. Products 86 inches and above in particular need to confirm these conditions in advance.

10. Meeting Room Procurement FAQ

XI. Common Procurement Mistakes

Meeting room whiteboard selection, the most prone to "size seems reasonable, the actual does not match"

Myth 1: Only select the size according to the number of people at the meeting

For the same 10 people, the depth of the room may be completely different. The farthest seat shall be measured at the same time.

Misunderstanding 2: Only select the size according to the size of the conference room

The long meeting room needs a bigger screen. Area cannot be used as a substitute for viewing distance.

Misunderstanding 3: 55 inches low price is preferred

If the back row is not clear, the savings in procurement costs may be offset by inefficient meetings and repeated communication.

Myth 4: 86 inches must be better than 75 inches

Small meeting room installation 86 inches may cause pressure and installation waste. Should be selected based on content and distance.

Myth 5: Only compare hardware prices

Camera, microphone, OPS, bracket, software, DMS, installation and after-sales will affect the final budget.

Myth 6: Do not do real file testing

The publicity video is clear and does not mean that the customer's PPT, Excel, CAD or conference platform experience is good. Application of real data acceptance.

Conclusion: How big a screen should the conference room buy? The answer is hidden in the last seat and the smallest text.

55 inches for small discussion rooms and close collaboration. The 75-inch is suitable for standard conference rooms, departmental meetings and medium-sized training. 86 inches for large meetings, training and complex content presentations. The final choice must be a combination of headcount, maximum viewing distance, content type, system, installation, and budget.

The core of meeting room whiteboard size selection is not "buy the cheapest" or "buy the largest", but let everyone see the content, participate in the discussion and complete the collaboration. 55 inches is suitable for small close spaces, 75 inches is suitable for most standard conference rooms, and 86 inches is more suitable for scenes with more people, farther distances and more complex content.
