In August of 2020, the BBC reported that roughly 10-12 percent of the world is left-handed. And that is an increase from only three percent 100 years ago. University College London’s Chris McManus wrote in Right Hand, Left Hand that an above-average quota of high achievers have been lefties as their brains are structured in a way that increases their abilities. Barack Obama, Oprah Winfrey, Bill Gates, Paul McCartney, Marie Curie, Jimi Hendrix, Ruth Bader Ginsburg, Leonardo da Vinci, David Bowie and Lady Gaga are among the world-famous lefties. 


So why isn’t every product designed to include the southpaw user experience? As a lefty myself, I pursued my engineering career in part because of my frustration over the lack of left hand-friendly consumer products. 

Ever think about how left-handed people zip up their jackets, use scissors or swing golf clubs? If you’re not a lefty, probably not. Righties don’t often consider that the world was designed for them -- for example, all door handles turn to the right. The lefty experience is backwards. 

Centuries ago, product inventors were more thoughtful – for example, the design of a paint brush — it doesn’t matter which way you hold it. But now that product design is much more speedy and technically driven, considerations like that often fall by the wayside. Here are my tips for making sure your product design is not “left out”:    

Put buttons and handles in the middle

Whether it’s a website, microwave oven or chainsaw, your left-handed consumers are going to appreciate not having to awkwardly reach or drag their mouse to the right to make things work. A center location is easy for everyone. But if you absolutely must put buttons or handles on the right, consider making them extra-large. 

Remember that it’s not just easy-to-reach button and handle placement that improves the product effectiveness for lefties: Oftentimes, something as simple as using a right-handed pen can be physically uncomfortable for a southpaw, as their stronger hand is not doing the work. Making things more ergonomically correct for your left-handed consumers will also encourage brand loyalty.

Test-drive your product with both hands

Besides the one-percent ambidextrous population, everyone has a dominant side and it’s easy to forget dual-handed product testing. Mark this off a checklist before your design is complete.   

Be friendly, but don’t go nuts

If you are designing specifically for a left-handed market, note that the consumer price for your product will be higher than similar right-handed items as there is not as much demand for them. Although many lefties would argue that they’d happily pay to make their lives considerably easier. Most product design, however – especially with software and online or electronic products -- is a balancing act. 

In reality, the percentage of left-handed consumers actively using your product is probably lower than that of your physically impaired or colorblind users. Moving keys or rearranging layouts for lefties doesn’t make sense if it damages user experience for right-handed people. A magnified above-finger view on a touch screen, for example, helps all consumers navigate websites easily.
