Only about three in every 100 births results in twins and, given this rarity, it's no surprise these twins with YouTube channels are inherently interesting to many. Many wonder what it would be like to grow up with a sibling who shares your exact age and - in the case of identical twins - your exact DNA. These famous YouTube twins allow curious viewers to catch a glimpse into the ins and outs of twin life.
The most popular twins on YouTube each approach their channel from a different angle. The Martinez Twins - a set of identical twin boys - upload mostly comedic videos featuring vlogs, pranks, and other content without a super specific hook or format. Twin girls Niki and Gabi have dubbed themselves "the girly-girl and the hipster." While they're identical, their channel focuses on beauty and fashion tutorials highlighting their vastly different styles and personalities.
Other good twins who have YouTube channels include the Merrell Twins, the Dolan Twins, Lucas and Marcus AKA the Dobre Twins, and even WWE tag team, the Bella Twins.
