Given that the Samsung QN100QN80FF carries a 15-inch larger screen, its physical footprint is expectedly bigger — wider at 2230 mm versus the Insignia's 1890 mm, and taller by nearly 190 mm. Anyone planning a wall installation or selecting a TV stand should account for that difference carefully, as the Samsung will demand significantly more horizontal real estate in the room.
What is genuinely surprising is that despite its larger panel, the Samsung is actually lighter at 27.4 kg compared to the Insignia's 29.9 kg — a roughly 2.5 kg difference. More striking still is the thickness gap: the Samsung measures just 58.4 mm deep, versus the Insignia's 93.2 mm, making it nearly 40% slimmer. That slimmer profile is reflected in the Samsung's lower total volume (165,727 cm³ vs. 190,644 cm³), meaning it occupies less physical bulk despite its larger screen area. For wall mounting in particular, a thinner chassis sits closer to the wall and presents a cleaner, more integrated look.
Both TVs support VESA mounting, so installation flexibility is equal on that front. Overall, the Samsung holds a clear design advantage — it is simultaneously lighter, thinner, and more compact in volume than the Insignia, which is a notable engineering achievement at 100 inches. The Insignia's smaller footprint in width and height may suit tighter spaces, but anyone prioritizing a sleek, low-profile installation will find the Samsung the more refined physical package.
