Radius Global Market Research is one of the largest independent market research companies in the world and they just released a study shows most kids (58 percent) can’t read content on 70” monitors.
The study was conducted with 106 students ages 12-to-22 in groups of approximately 30 at a time. Students were asked to read typical education content including charts and text-based information displayed on a top-selling 70-inch flat panel in a traditional 30-foot-by-30-foot classroom, and then write down six short items of information from what they saw. The students sat in five rows 22-feet wide (six seats per row) with the first row approximately eight feet from the display, and the last row about 27 feet from the display.
The overall results indicated that, on average, 17 out of 30 students per classroom were not able to read the content on the 70-inch flat panel, defined as writing down at least one item incorrectly.
“The majority of students evaluated in the study clearly had difficulty reading the content displayed on the 70-inch flat panel,” said Shira Horn, vice president, Radius Global Market Research.
The research findings support the 4/6/8 Rule for display size recommendations. The 4/6/8 Rule is a long-standing guideline commonly used by AV integrators and installers for determining the appropriate sized displays for different environments including classrooms, conference rooms and large venues.
Further, the results of the study are also consistent with the InfoComm DISCAS draft standard published by InfoComm International, the trade association representing the professional audio/visual and information communications industries worldwide. Using the DISCAS draft standard to calculate the Farthest Viewing Distance for Basic Decision Making — a 70-inch display would not be recommended for viewing text based educational content at distances of approximately 18 feet and beyond.
The study was funded by a projector manufacturer, Epson, but Radius Global Market Research is cited as a top-50 research firms in the world.
