Read the full iPad Pro 12.9 (2021) review Plus, while it's great for professionals and creatives, not everyone will need the extras it provides - if that's you, the other iPads on this list are better for you. So why might you consider something else? Well, it's incredibly expensive - especially if you're considering 5G connectivity, or storage that goes anywhere near the max of 2TB. What does this mean? Well, it's a versatile and powerful little machine that we found handles video editing, loads of writing, drawing and animation and gaming with aplomb. You won't find a more powerful tablet (well, apart from other iPads) - it handled everything we threw at it.

The slate has a giant 2048 x 2732 Mini LED screen, an incredibly powerful Apple M1 chipset (also found in MacBooks and iMacs), compatibility with Apple's various keyboard folios and the Apple Pencil, and also up to 2TB storage.

The performance of navigation and fluidity of drawing will also depend on your iPad processor and RAM.We've picked the iPad Pro 12.9 (2021) as our favorite iPad because it ticks all the boxes you need for a professional tablet. So, for example, if you have 50Gb left on your iPad storage and a 1920×1080 pixels shot, you can add (50 000 000 000 / (1920x1080x4))/3= 2009 more sheets in the app. So consider this as a very rough estimation to have an idea of how many sheets you can add. Here is how to estimate your possible number of sheets depending on your remaining available storage : (remaining available storage in bytes / (height of your shot in pixels x length of your shot in pixels x 4)) / 3 = number of sheets you can add in Callipeg This calculation includes a rough estimation of the size of undos and backups, but this will depend on how many actions you do, the number of backups you have set and other conditions.

The size of one sheet equals the length of the shot in pixels multiplied by the height of the shot in pixels multiplied by 4 bytes. This limit depends on the storage of your device. You can have as many layers as you want, until you reach the sheets limit.
