Why 86 Inch Is the Most Popular School Screen Size in 2025
When school procurement teams submit tenders, one size comes up more than any other: 86 inch. It has become the de-facto standard for primary and secondary school classrooms in Southeast Asia, the Middle East, Latin America and Eastern Europe.
Why 86 inch won
The 86 inch interactive screen hits a practical sweet spot. At 1950 × 1159 mm, it fills the front wall of a standard classroom without touching the ceiling or the side walls. Students in the back row of a 10-metre classroom can read 14-point text clearly. Teachers have enough writing surface to display a full A4 document and annotate beside it simultaneously.
Compared to 75 inch, the 86 inch gives 30% more surface area — a significant difference when teachers are writing equations or showing engineering diagrams. Compared to 98 inch, it weighs 23 kg less (72 kg vs 95 kg), which matters when installing on existing walls not originally designed for heavy loads.
When to choose 75 inch instead
- Classroom depth under 8 metres
- Tight budget — 86 inch costs approximately US$230 more per unit
- Screen will be moved on a mobile stand (lighter is easier)
- Sliding blackboard bay width does not accommodate 86 inch
When to choose 98 inch instead
- Lecture halls with 60+ students
- Classrooms deeper than 11 metres
- University seminar rooms where detailed diagrams must be visible from the back

Bottom line
86 inch is the safest default choice for any standard classroom project. If your rooms are small or your budget is tight, go 75 inch. If your rooms are large lecture halls, go 98 inch. For everything in between, 86 inch is the answer most buyers land on — and stay with.
