If you find that you need more layers, you can always start with a smaller size. The only downside to this is that a larger canvas means you get fewer layers to work with. I want to make sure that the integrity of the piece stays intact when I scale up to large sizes like that, so I like to work with big canvases in Procreate. Most of my artwork needs to be at a very high resolution so I can include it on large-scale products like tapestries and bedding.

I personally like to create custom canvases when I'm working in Procreate. If I'm doing any kind of thumbnail sketch or anything that won't be exported as a final piece, I usually just work with a screen-size canvas. If you want to get started quickly and play around in Procreate, you can easily get started by selecting 'Screen Size.' This is exactly what it sounds like - a canvas that is exactly the size of your screen! It's great for doodles and learning the ropes of Procreate. Procreate comes with a few default options for your canvas size.
