Hi mcpbowman! Thank you for your response!,
I think your right when page size dont matter and I also grab any notebook that is next to me for enjoyment which is not usually standard sizes. However when I find the sketch is worth presenting even though A3 provides a better prentation I am stuck with having pages a little bigger than A4 and less larger than A3 which is one of my favorite pages sizes to sketch with.
Haha, this topic may not seem that interesting but I see many designers struggle with this especially if they want to keep their work presented consistently. I believe thats great that you mcpbowman choose those sizes to keep yourself consistent.
And thank you, i will post some sketches in the doodling section soon for sure!
