Teaching at Scale: Why 75-Inch Digital Boards Offer the Perfect Classroom Fit
When it comes to upgrading your teaching setup—whether in a school classroom or a coaching center—choosing the right screen size is often the first big decision. While 55-inch or 65-inch boards may suffice for smaller rooms, a 75-inch digital board strikes the perfect balance between visibility, power, and price for most educators in India.
In this blog, we’ll take you through a use-case-first lens—starting with how these boards work for different types of teachers, how pricing compares to real-world value, and why the 75-inch form factor dominates modern education spaces.
🎯 Why Are 75-Inch Digital Boards So Popular Among Teachers?
The trend toward 75-inch screens isn’t just aesthetic—it’s functional. Teachers increasingly prefer this size because:
- It covers medium to large classrooms (25–50 students)
- It’s visibly clear even from the last bench
- It accommodates large-format content—like equations, maps, diagrams, or split-screen notes + video
- It still fits on most walls without needing auditorium-scale mounts
