Although the ultimate solution is to make it easy for users to increase or decrease font sizes at will. Fonts should be a minimum of 16px (some sources report 12px is sufficient, but larger is better in this case). Basically, anything that’s meant to be read or clicked should be scaled up. Text and button sizes should be kept large. Overall, color contrast should be increased in websites and apps that cater to older adults. Shades of blue can also appear faded to seniors, potentially reducing contrast when blue elements are used in a design.
Many older adults use reading glasses or opt for much larger font sizes when given the option. And considering that there are over 75 million baby boomers in the US (the youngest of which are turning 55 this year), it’s likely that at least some of them are visiting pretty much any website online.Īs people age, a number of changes commonly happen to their vision. It’s vital that UI designers consider visual accessibility when creating websites that are likely to be accessed by older adults. Vision loss is the most common disability reported in adults in the United States, with an estimated one in six people over the age of 70 reporting vision impairment. Visual Elements for Users with Impaired Senses Tiny interface elements on mobile devices are a nightmare for more than just older adults. UX and UI designers need to understand these changes in order to effectively master interface design for older adults. They need incentives to engage and may have vastly different usage patterns for things like apps compared to their younger counterparts.Īs the population ages, though, more “seniors” will be comfortable with technology and only need compensation for actual physiological and cognitive changes. Nevertheless, there are also older adults who aren’t as comfortable or familiar with technology in general, or more specific things like mobile devices. And while many who are over sixty have been around technology almost their entire adult lives, those physiological and cognitive changes need to be compensated for. Globally, the group of people over sixty is growing more rapidly than any other demographic.Īs people age, there are certain physiological and cognitive changes that are almost inevitable. According to the 2017 World Demographic Perspectives: Revised Report, it is expected that the number of people over the age of sixty will more than double by 2050 (from 962 million to globally to 2.1 billion), and triple by 2100 (to 3.1 billion).
