The selection of a smart board starts with the task to be performed, the distance of the farthest viewer, and the area the instructor uses for writing. This article compares sizes from 55–86 inches and what to try with a real classroom, such as readability, connectivity, and installation.

What is a Smart Board?
A smart board or interactive board is a display surface that supports touch and writing. Some models are flat screens with built-in systems and speakers, while some systems use projectors or separate computers. Choose based on the classroom format and the devices that need to be connected.
How a Smart Board Works
Understanding what an Interactive Whiteboard is starts with learning the internal working system of the device. These smart screens work by integrating advanced hardware with specialized software.
Touch Detection System
Some interactive screens use infrared sensors around the edges of the screen to detect the position of fingers or pens. Touch technology, number of points, and types of pens supported vary by model.
Coordinate and Signal Conversion
When a touch is made on thewritable TV, the position is converted into digital coordinate data in an instant. These coordinate data are sent directly to the processing unit to analyze the direction, weight, and lines drawn by the user.
Processing Unit
Some models have an internal operating system, while others connect to an external PC or additional computer module. Check that the required application works on the system and model selected.
Display and Software
Supported software may include whiteboards, file opening, or screen sharing. Test actual file opening and recording export before purchasing.

Smart Board: How Many Types Are There?
The following sizes can be used as a starting point for testing. Use real files and sit at the farthest position. The number of users alone cannot determine the appropriate size.
55-inch Size for Limited Space
The 55-inch size is suitable as an option when space is limited and the audience is close to the screen. Try opening the smallest text or chart in the actual document set.
65-inch Size for Team Meetings
The 65-inch size provides more space for writing and displaying slides. Test it when opening the app with a meeting window or screen sharing.
75-inch Size for Classrooms or Training Rooms
The 75-inch size is suitable for testing in multi-row training rooms. Check readability from the back of the room and the height the instructor can write up to.
86-inch and Above for Large Organizations
The 86-inch and above sizes provide more space, but you must check the transportation route, weight, mounting points, and the actual viewing distance before installation.
Smart Board Maintenance
In order for the Smart Board to have a long lifespan, proper maintenance is important. Maintenance of the Smart Screen can be divided into the following practices:
Proper Cleaning of the Screen
Turn off the device according to the manual before cleaning. Use a soft, non-abrasive cloth and cleaning solution approved by the manufacturer. If the manual specifies the use of liquid, soak the cloth and avoid spraying directly onto the screen.
Care of the Sensors Around the Screen
If the screen uses an infrared frame, clean the edges according to the manual without pressing or prying the sensors. If the touch is distorted, check for obstructions and test the settings according to the model.
Updating the Operating System and Software
Check the models and versions supported by the manufacturer before updating. Test the app, touch, and screen sharing after the update during a non-disruptive training period.
Smart Board Usage in Industry
In the manufacturing industry, Smart Boards have become an important tool for improving work efficiency. Writeable TVs have become a tool that helps reduce the complexity of coordination.
Real-time Production Data Analysis
Use the screen to open dashboards from authorized systems to view shared data in the meeting room. The freshness of the data depends on the source system and network. Machine operation tasks use the control section designed for that machine.
Planning and Improving Production Processes
Factory managers can upload floor plans or production process diagrams onto the Smart Board. The team can write, draw lines, and link relationships to freely plan and improve the production line together.
Training Employees and Technicians
Explaining the operation of complex machinery is easier through the Smart Screen. Instructors can open 3D images, zoom in on components, write explanations of precautions, making employees clearly understand safety procedures.
Advantages of Smart Boards
If you wonder why Smart Boards are important, investing in Smart Board technology will provide valuable returns for your business. Switching to Smart Screens has clear advantages as follows:
Enhance Meeting Participation
Writeable screen transforms one-way meetings into two-way interactions. Attendees can write down ideas and highlight important text on the screen themselves, capturing the team's attention throughout the project presentation.
Save Time and Reduce Paper Usage
Engineers can capture screenshots with handwritten notes on the Interactive Board and send them directly to the participants' emails, reducing the need for note-taking, minimizing paper printing, and meeting sustainability goals.
Wireless Connectivity and Free Data Sharing
Wireless screen mirroring depends on the screen model, protocol, source device, and network settings. Test with the actual phones and computers used by the team.
Integrate All Devices in One Unit
Some All-in-One screens combine display, touch system, computer, and speakers in one unit. Check if the equipment required in the room, such as cameras or microphones, are included in the model or need to be added separately.
How to Choose a Smart Board
When considering the purchase of a Smart Board, you must take into account engineering factors to achieve maximum value. If you want to know what the principles of purchasing an Interactive Whiteboard are, you can use these criteria to make your decision
Choose the distance and size based on the farthest viewer's position. Use slides, charts, and real text to test readability before purchasing.
Check the touch technology: Choose a model that responds quickly and supports multi-touch for simultaneous touches to ensure smooth and uninterrupted use of thewriteable screen during brainstorming sessions
Inspect the ports from both the source and the screen, especially whether USB-C supports video and touch, as well as test HDMI with a USB cable for touch according to the manual.
Check the dust, temperature, reflection, weight, and mounting points. Have the installer use a stand or mounting kit that supports the screen's model and weight.
Check the warranty period, update cycles, and the scope of installation or repair services. Request the service conditions in writing.
Reliable Smart Board Brand
The decision to invest in a Smart Board brand depends on the nature of your organization. If you are looking for a high-quality Interactive Board, we have the following preliminary evaluation recommendations
International standard brands: Choose a Smart Board from a manufacturer that is recognized for image technology and touch sensors to guarantee hardware quality
Software that comes with the device: Some Writeable TV brands come with easy-to-use presentation software, no additional annual costs, which can significantly reduce total cost of ownership (TCO)
Support from local agents: Smart Screen devices purchased through trusted agents will receive better technical support and faster warranty service
System integration capability: If you want to know whether Interactive Whiteboard is the right choice, you need to assess how smoothly the Writeable Screen brand works with your factory's existing network system
