a few straightforward rules of thumb can help ensure that you are selecting a functional product.
Video presentation happens everywhere, everyday. Whether it’s a PowerPoint presentation, promotional video or detailed architectural floor plan, it’s important that all viewers can clearly see the content in order for the presentation to be effective. An increasing number of organizations are implementing their own display solutions, due in part to the availability of high-quality, cost-effective displays through local “big box” retailers. When it’s time to make that purchase, how do you know if you’re buying the appropriate screen size?
While we always recommend consulting with a professional before purchasing technology, a few straightforward rules of thumb can help ensure that if you take on the responsibility of acquiring a display for your office or facility, you are selecting a functional product.
The first thing to consider is the most common content that will be viewed on the display. We break content into three main categories: video, PowerPoint, and detailed drawings/text. These categories are based largely on the amount of detail present. For example, it is much easier to glance at a display from across a room and discern that the video shows a bird landing in a nest, rather than observe that your Q1 2014 sales had increased by $52,344.22 over 2013’s. In between those two content detail extremes lies the PowerPoint presentation. Although these presentations typically consist of a combination of text and graphics, a good PowerPoint presentation provides an overview or outline of the subject matter and doesn’t present a high degree of detail. As such, it ends up being the middle ground in terms of ease of viewing.
To help determine the appropriate display size, the amount of detail contained in a presentation will be represented using the following “content factors”:
- Video = 8
- PowerPoint = 6
- Detailed Drawings/Text = 4
The second consideration is distance. In the previous example, the viewer must move closer to the display to clearly read the content of the sales reports. In other words, the closer the viewer is to the display, the more content detail he/she will be able to discern. If the new display is to be located in a conference room, measure the distance between the location of your display and the position occupied by the most distant viewer. By knowing this distance and the type of content most often displayed, the necessary display height can be calculated using the simple formula:
DH = DFV/CF
Where:
DH = Display height
DFV = Distance to farthest viewer
CF = Content factor
Recalling the content factors, this formula translates to the most distant viewer being located no more than eight times the display height away for video, six times the display height for PowerPoint presentations, and no more than four times the display height away for viewing detailed text.
Let’s look at an example. A small, 20’ x 14’ conference room is used frequently for “lunch and learn” presentations. A flat screen display is desired for presentation purposes, and it will be located on the front 14’ wall. A rectangular conference table is present, and the seat farthest from the display is located 16’ away. How tall must the display be in order to accurately view the presentation content from this seat?
CF for PowerPoint = 6
DFV = 16’
DH = DFV/CF
DH = 16’/6
DH = 2.6’ or 31.2” high
Be aware that this height refers to the viewable image height and not the overall height of the display hardware. Also note that display manufacturers classify their products by image diagonal, and not by image height. A 31.2” height is likely to be found on a 65” display, so you’ll want to look at the specific product’s specifications prior to purchase.
If the room is sufficiently large, it is possible that your calculations will reveal a recommended minimum height that is greater than that provided by any currently available flat screen display. At this point, different display technologies such as projection or display walls may be considered.
Keep in mind that this formula is about establishing a basic guideline and getting you “in the zone” for acceptable viewing based on content. While there are many other variables (resolution, room lighting levels, type of display technology, etc.) that go into proper presentation system design, understanding how to size a display is critical and can help you avoid at least one common pitfall when implementing a presentation system display.
