Interactive Flat Panel Size Comparison

One table, every size. Start from the depth of the room rather than the budget — an undersized panel is the most common and most expensive mistake schools make.

How to Choose the Right Size

Measure the room, not the wall

The rule that matters is the distance from the panel to the back row. A screen stays comfortably readable to roughly four times its diagonal: about 20 feet for a 65-inch, 25 feet for a 75-inch, 29 feet for an 86-inch. Measure that distance first; the wall will almost always take whatever size the room needs.

Count the seats, then add a row

Class strength rises. A panel bought for 35 students that has to serve 45 two years later is a panel that gets used less, because the back row stops reading it. Where the choice is genuinely between two sizes, the larger one ages better.

Check what the wall can carry

A 75-inch panel weighs about 42 kg and an 86-inch about 51.5 kg. Brick and RCC walls carry that on a fixed VESA mount without preparation. Partition and drywall classrooms need a backing plate or a mobile floor stand, which we specify at survey rather than on delivery day.

Mounting height

Set the bottom edge 110–125 cm from the floor so the working area of the screen sits at a standing teacher's eye level. Too high and teachers stop writing on it; too low and the front row blocks it.

What Every Panel We Supply Has

4K Display

3840 x 2160 resolution, 60 Hz, LED or DLED backlight. Bright enough to read in a classroom with the lights on and the curtains open — the single biggest practical gain over a projector.

Multi-Point Touch

20 to 40 simultaneous touch points with infrared sensing and palm rejection, so students can work at the board together and a teacher can rest a hand while writing.

Built-in Android

The panel runs on its own — whiteboard, browser, file manager and apps — with no classroom PC. Google EDLA-certified models add the licensed Play Store, Classroom and Meet.

Wireless Screen Sharing

A teacher's phone or laptop mirrors to the panel without cables, so lesson material prepared at home opens in the classroom in seconds.

Full Port Set

HDMI in and out, USB-A and USB-C, LAN, and an OPS slot on most models for a slot-in Windows PC where desktop software is required.

No Consumables

No lamp, no filter, no markers, no duster. Running cost after purchase is electricity and nothing else.

Frequently Asked Questions

What is an interactive flat panel?

An interactive flat panel is a large 4K touchscreen display, usually 65 to 98 inches, built for classrooms and meeting rooms. It combines the display, the touch surface, the speakers and, on Android models, the computer into one wall-mounted unit. It replaces a projector, a whiteboard, external speakers and often the classroom PC. Smart board, digital board and interactive panel all refer to the same device.

Which interactive flat panel size is right for my classroom?

Work from the depth of the room. A 65-inch panel is readable to about 20 feet and suits 25-35 students. A 75-inch reaches about 25 feet and 35-50 students, which covers most Indian classrooms and is the size we supply most often. An 86-inch covers roughly 29 feet and 50-60 students. A 98-inch is for auditoriums and assembly halls where the back row is beyond 30 feet.

How much does an interactive flat panel cost in India?

As of 2026, 65-inch panels run Rs. 1,05,000 to Rs. 1,54,000, 75-inch Rs. 1,33,000 to Rs. 2,38,000, 86-inch Rs. 2,10,000 to Rs. 3,64,000 and 98-inch Rs. 4,20,000 to Rs. 7,00,000. The spread within each size comes from the brand, the touch technology, whether an OPS Windows module is included, and order quantity. CBM IMPEX prices include delivery, wall mount, installation and teacher training.

What is the difference between an interactive flat panel and an interactive whiteboard?

An interactive whiteboard is a passive surface that needs a projector and a computer to work. An interactive flat panel is a self-contained LED display with its own processor and operating system. The panel is brighter in a lit room, has no lamp to replace, no shadow when a teacher stands in front of it, and no calibration drift. Panels have effectively replaced interactive whiteboards in new school installations.

How long does an interactive flat panel last?

The LED panel is rated for 50,000 or more hours, which works out to 7-10 years of normal school use. There are no consumables and no moving parts. Standard manufacturer warranty is three years, extendable to five. The practical limit is usually software rather than hardware, which is why an EDLA-certified panel with a current Android version is worth paying for.

Do interactive flat panels need a computer connected?

Not on Android models. The panel boots into its own operating system with a whiteboard, a browser and, on EDLA-certified panels, the full Google Play Store, Google Classroom and Meet. A laptop or an OPS slot-in Windows PC can still be connected over HDMI or USB-C when a teacher needs specific desktop software.
