If you like looking up and down more than side to side, vertical calendars are the way forward. Ours are a huge 30" x 40" so you have plenty of room to actually write down your daily schedule plus your tasks and deadlines.
Each month has a section for focus and notes, plus there's an area for a key if you're a fan of color-coding, and a section called remember so you can write down your theme or focus for the whole year (or jot down things you'll need to recall going into 2022).
If you like to plan your year from left to right, horizontal calendars are where it's at. Ours are a massive 40" x 30", so you can survey your whole year at a glance and have plenty of room to write down all your plans.
Each month has a large space for focus and notes, plus there's areas where you can create your own key and make a note of what you want to remember for 2021. When you're going to look at something every single day for a whole year, it should be functional and beautiful.
