Proper planning and design for attention-grabbing exterior wayfinding signs

Installing a sign in the outdoors takes some planning and creativity to capture the attention of drivers glancing at the roadside and pedestrians going by buildings at obviously slower speeds.

Either way, the messages on the signs have to be read quickly, resulting in additional requirements that indoor signs do not have.

“The biggest problem I have with wayfinding that I find from a sign design perspective is people want to put too much on a sign,” says Jim Brown, exterior products manager of Takeform, a wayfinding consulting and fabrication company in Medina, New York, in business for 20 years. “They don’t need all the information on a sign; it could be detrimental.”

Brown says a line or two often is better than a paragraph of information.

“The sign needs to be functional. It has a job to do, and you need to let it do it,” Brown says. “You have to determine where you want to get people, where you want people to go.”

One way to do that is to start with an exterior site survey of the area where the sign will be placed, says Bill Freeman, vice-president of architectural sales for Howard Industries, a sign manufacturing company in Fairview, Pennsylvania.

“The best practice is to view the site as a ‘first-time’ visitor,” Freeman says. “Once all of the site data is collected, you are able to recommend signage placement and messaging.”

Freeman recommends assessing traffic patterns for both vehicles and pedestrians where applicable, photographing the area of the sign’s placement and making note of any points along a travel route where navigational decisions need to be made.

The decision points can include a T in the road, an entrance to a property or the outside of a building, Brown says. Exterior wayfinding signs may give directions, offer a directory or present a site plan with a list of the buildings on the property, he says.

The Content of Exterior Wayfinding Signs

The content of the signs needs to help with the decision process, taking into account things like viewing distance versus the speed of traffic and if the signs are geared to an audience of drivers, bicyclists or pedestrians, Brown says. The design for a roadway sign with higher speed limits will require larger letters for that proper viewing than a sign for a lower speed area.

“There are legitimacy charts to determine the height of the letters versus the speed you’re going,” Brown says.

The font is an important consideration, as is what the copy will be made out of, Brown says.

“Obviously, you want to use a font that’s legible,” he says, recommending avoiding fonts with fancy script or that are hard to read. “For the actual body of the sign giving directions, you want to be able to read it, as opposed to having it just look pretty.”

For optimal readability, signs geared to drivers should be placed perpendicular to the roadway in direct view of their line of sight, Freeman says.

“Proper copy size, layout design and color combinations ensure successful visibility of any wayfinding sign,” he says. “Keep wayfinding messages clear and concise and choose contrasting color combinations that promote legibility.”

The Sign’s Shape and Size

The size and shape of a sign, such as if it is rectangular or square, are other important factors, says Natalie Whited, vice-president of marketing at Orbus Exhibit & Display group, a division of SignPro Systems, a trade show supplier and manufacturer in Woodridge, Illinois.

“Size is a key question,” Whited says. “It would depend on the environment. … What kind of environment and needs do you have? You almost have to have a needs analysis done in order to suggest the right solution.”

When creating the sign, getting the dimensions to be precise is critical for the installation, Whited says.

“If they are off a little bit, they can screw everything from the presentation to the end environment,” Whited says.

The height of the sign may be limited by town or city code, or the sign may need to follow a minimum size requirement in the case of a stop sign or parking sign, Brown says.

“It is very important for sign companies to know the zoning requirements and restrictions of municipalities where they plan to install wayfinding signage,” Freeman says. “Before designing a wayfinding signage plan, research sign size restrictions and placement requirements.”

Considering the physical area where signs will be installed also is important to retain their visibility factor.

“Since exterior wayfinding signage is placed in an outdoor environment, signs can become quite large and impressive in appearance,” Freeman says. “Architectural design elements from nearby buildings can be incorporated into their designs, creating an aesthetic unity and overall captivating and interactive experience for the viewer.”

Takeform does this by designing exterior wayfinding signs to fit with the environment and the customer’s identity, reflecting a building’s architecture or a company logo, Brown says.

“It’s more aesthetically pleasing,” Brown says. “The whole idea is to tie everything together.”

Another factor in sign placement is a customer’s need for modularity, especially for organizations that undergo constant change, such as colleges, universities and hospitals, Freeman says.

“Offering a signage system that can be easily updated is a strong selling point for these types of clients,” Freeman says, recommending avoiding flush face signs with routed copy that does not lend well to alterations. “Signs with removable panels and vinyl copy are more economically sound design options.”
