When customers ask about interactive whiteboards, one of the first questions is almost always:
“What size should I choose?”
On paper, the answer looks simple.
Bigger screen, better experience — right?
But in real-world projects, especially in education and commercial environments, screen size is one of the most misunderstood parameters. Choosing the wrong size doesn’t just waste budget — it can reduce usability, shorten lifespan, and create long-term maintenance issues.
At Qtenboard, we manufacture interactive whiteboards in 55, 65, 75, 86, 98, 105, and 110 inches. And after years of factory production, project delivery, and customer feedback, one pattern is very clear:
65”, 75”, and 86” are consistently the best-selling sizes — for very good reasons.
This article explains what each size is really suitable for, why some “bigger” options don’t always make sense, and how Qtenboard approaches size selection from a factory and engineering perspective.
Most buyers compare size the same way they compare TVs at home:
But interactive whiteboards are not consumer TVs.
They are:
That changes how size should be evaluated.
Qtenboard’s standard interactive whiteboard sizes are:
This range is not random. Each size exists because it fits a real usage scenario, not because it looks good on a spec sheet.
Let’s go through them one by one.
Typical scenarios
Why choose 55”
Limitations
At Qtenboard, 55” is usually chosen when space is the main constraint, not when visibility is the priority.
Typical scenarios
Why 65” sells so well
For many first-time buyers, 65” is the safest choice. It fits most rooms without requiring structural changes or special mounting considerations.
This is one of Qtenboard’s highest-volume production sizes, optimized on both automated and manual assembly lines.
If we had to name one size that represents the “modern classroom standard”, it would be 75 inches.
Typical scenarios
Why 75” performs so well
From a factory perspective, 75” offers:
This is why 75” remains one of Qtenboard’s best-selling and most stable models.
86 inches is where interactive whiteboards truly enter the professional-grade category.
Typical scenarios
Why 86” is a top seller
At Qtenboard, 86” is a core size:
It is large enough to feel impressive, yet still practical for daily interactive use.
98” starts to push the limits of traditional classroom installation.
Typical scenarios
Things to consider
While 98” can be a good choice in the right environment, it already requires careful planning — not just “bigger is better” thinking.
This often surprises customers:
“Why is 105 inches more expensive than 110 inches?”
The answer lies in panel origin and production logic.
105” panels:
In many cases, 105” panels are true commercial-grade LCD panels, not consumer TV derivatives.
From a factory standpoint:
This is why 105” can cost more than 110”, even though the number is smaller.
110” is the maximum size Qtenboard offers, and we are very careful about how we position it.
Why we do not actively recommend sizes above 110”
More importantly:
Above 110 inches, most “interactive whiteboards” in the market are likely TV-converted products.
As discussed in our Buying Guide series, consumer TV panels are not designed for:
This is why Qtenboard does not promote ultra-large sizes as a default solution.
This is not marketing preference — it’s usage reality.
These three sizes:
From a factory perspective:
That’s why Qtenboard invests the most resources into perfecting these sizes.
Qtenboard uses a hybrid production system:
Robotic Assembly Line
Manual Verification Line
This dual system allows us to:
Bigger screens demand tighter control — not looser standards.
Instead of asking:
“What’s the biggest size I can afford?”
Ask:
In most real scenarios:
Choosing the right interactive whiteboard size is not about chasing numbers.
It’s about matching space, usage, reliability, and manufacturing reality.
At Qtenboard, our size recommendations are based on:
Sometimes, the smartest choice isn’t the biggest one —
it’s the one that works best, every single day.
