Samsung Flip Pro 65 vs 75 vs 85 Inch: Does Bigger Actually Mean Better?

Not always. On an interactive display, size has to suit two people: the one standing at the board writing, and the one at the far end of the table reading. A bigger screen helps the reader but makes the top of the board harder to reach and the room harder to fit. As a rough guide, the 65-inch Samsung Flip Pro suits huddle rooms up to about 4 m deep, the 75-inch medium rooms up to about 5.5 m, and the 85-inch larger rooms and training spaces up to about 6.5 m. Cost rises faster than size at the top end. At SourceIT, the 75-inch Flip Pro WM75B is S$4,875 and the 85-inch WM85B S$8,455 (listed 31 Oct 2026), an extra S$3,580 for 10 inches.

How do the three sizes compare?

Picture sizes and viewing distances are our calculations for a 16:9 screen using the traditional 4/6/8 rule of thumb, not vendor figures. SourceIT prices listed 31 Oct 2026; the WM65B and WM85B are not currently in stock, so ask us about availability.

How do you size a screen properly?

The audiovisual industry body AVIXA publishes a standard called DISCAS (Display Image Size for 2D Content in Audiovisual Systems), which replaced the older 4/6/8 rule. It separates two kinds of viewing. Basic decision making means viewers only need to follow the content, such as slides or a video call. Analytical decision making means they must read every detail, such as spreadsheets or drawings. The second needs a much larger picture for the same distance. AVIXA's calculator is free to use online, and for a room where people will study detailed content, it is worth running before you buy.

A quick check for analytical content shows why. In a large room 7.5 m deep, the 4x rule calls for a picture about 1.9 m tall, nearly twice the height of an 85-inch screen. No single interactive display covers that, which is why large rooms usually add a second screen or move detailed content onto laptops.

The right size is the one the back row can read and the front row can reach.

Why can bigger be worse on a touch board?

• Reach. An 85-inch picture is about 1.06 m tall. If the bottom sits at a comfortable writing height, the top is close to 2 m above the floor, out of easy reach for many people.
• Mounting height. Draper, a screen maker, suggests the bottom of a viewing screen sit at least 48 inches (about 1.2 m) above the floor so heads do not block it. A touch board is often mounted lower, so people can write on it, which means those at the back see more of the people in front.
• Walls and doors. An 85-inch board is nearly 1.9 m wide before the frame. Check the wall, the lift and the door before ordering.
• Portrait use. Samsung's Singapore page for the newer Flip says rotation is supported on the 55 and 65 inch only, so a flip-chart style portrait setup needs the smaller sizes.

Which size suits which room?

• 65 inch: huddle and small rooms for about two to six people. Zoom's room guide describes this as a room of about 3 x 3 m. Also the size to choose for a mobile stand.
• 75 inch: medium rooms for about seven to twelve people, about 4 x 6 m in Zoom's guide. The most balanced choice for writing and viewing.
• 85 inch: large rooms, training rooms and workshops where the board is the main focus and people stand to use it.

If the room is mostly used for video calls and presentations, a non-touch screen may be the better buy at any size; see Samsung Flip Pro vs a Regular 75-Inch TV. The 86-inch question across brands is covered in The 86-Inch Interactive Display Debate, and room planning more generally in Choosing the Perfect Display for Your Meeting Room.

Flip Pro or the newer Flip at each size?

At 65 and 85 inch, the newer Flip is listed below the Flip Pro and is brighter, at 450 nits against 350. At 75 inch, the Flip Pro WM75B is S$1,225 less than the WM75F and is in stock. The Flip Pro is rated for 16 hours a day, against 12 for the newer Flip on Samsung's Singapore page. A full review is in Samsung Flip Pro Review.
