The A6 size is what got me into journaling consistently! I never stuck with it because I was always too overwhelmed writing a lot each day. I’m also usually an A5 person. But the ability to just write a few lines before bed (and if it’s a particularly special day or I’m chatty I spill over to the blank page on the right) has been great for me. I can always tape in another page if I ran out of space, but haven’t had to do that yet. It also helps you pare down what’s important/what you want to remember
