Space depth x number of students-before purchasing large-size interactive whiteboards, confirm the "bottom line size" to avoid rework if you buy small ones.

It's not just "big": the last row of viewers can see every word clearly, which is the acceptance standard for super-large space procurement.
Shot from the last row of the auditorium (about 10 meters), the text and charts are still legible. When displaying architectural blueprints, medical images, engineering drawings, and 4K video, the details are in the slightest-this determines the "arrival rate" of the content of each event ".
The viewable area of 110 inches is about 45% higher than that of 98 inches, which is about 1.8 times that of 86 inches. A budget is only well spent when it’s allocated to visible, tangible outcomes.
The 110-inch "comfort zone" is multi-person collaboration: the screen is large enough to hold the sense of participation in the whole event.
Support 10 people at the same time writing, drag, zoom, operation, do not interfere with each other
The 110-inch complete machine is about 2470 × 1420mm, with wide blackboard writing and multi-person partitioned writing without pressure.
The writing follows the hand and the handwriting is smooth, and the demonstration annotation has zero waiting.
110 inches is the "top flagship", with a higher decision-making level and a longer decision-making chain-every level has a reason to buy it.
110 inches weigh 70-85kg, and installation is the biggest concern in purchasing decision-making-professional engineering scheme, which can be eliminated at one time.
The same "last row can't see clearly" problem, they solved with a 110 inch
"Our International Conference Center hosts dozens of academic summits and international forums every year. Previously, with projection, the guest PPT was complex and could not be seen clearly. After changing the 110-inch whiteboard, the delegates from 10 meters away could also see the paper data chart. The most shocking thing is the 8-screen function-the PPT of 4 keynote speakers is displayed at the same time, which is extremely efficient in comparison and discussion."
"We do the national agent conference, annual training, before the use of two pieces of projection splicing, there is always a seam and uneven brightness. 110 inches a screen to get everything, 500-600cd/m² brightness, the full light is also clear. Many partners ask 'what is this equipment', has become the company's image plus items."
"We have graduation ceremony, Christmas concert and parents' open day every year. The 110-inch vertical screen displays the activity posters and program lists very amazing, and the horizontal screen plays the students' works collection with shocking effect. Parents feedback that 'this is the configuration that international schools' should have '."

If your spaceMore than 80 people or more than 8 meters deep98 inches is "barely enough" and 110 inches is "really enough"-- About 30% more budget, 45% more visible area and higher brightnessIn exchange for the audience's "no longer squinting" experience 10 meters away.
If your spaceNo more than 200 people and no more than 10 meters deep, 110 inches is the best solution for cost performance-a larger size (e.g. 135 inches/165 inches) is a double budget, which is "over-allocated" in a space of 100-200 people, andInstallation difficulty, transportation costs and space requirements increase geometrically。
