We all have our own view of whether we are left-handed or not and, ultimately, that is the the test - if you consider yourself to be left-handed then you are! That said, most people are mixed in their handedness and it is rare for people to do everything with just one hand or side of their body. Our test below will show which side you use for various tasks and how consistent you are in the use of your hands. It will also give you give you an overall score out of 100 for your level of left-handedness and you can see how you compare to other people. To get the overall score, we have weighted the various factors so, for example, writing left-handed gets a far higher weighting in the overall score than which way you hold a bat two-handed (see this page for more information on how we did this).
