All I have is anecdotal about the US and I only remember due to the annoyance. I’ve moved six times in the last seven years. I have swapped the direction of my dryer door every time because the side hookups were on changed every time. My dryer is currently on the left. Prior to these moves I couldn’t say with 100% certainty but if I try to picture myself in that laundry room I think my dryer was on the left but it isn’t something I paid attention to until I had to swap the dryer door hinges every time I moved since so my dryer door would open away from the washing machine.
I used a website to calculate that for me because I’m an idiot and it all seems like magic to me.
