bed sizes are typically expressed in mm not cm. also the difference between 270mm and 305mm is huge when you need to print something that is 300mm. It's basically the line between full sized helmet and piecemeal helmet. For example my 256x256 is big enough to print myself a hat but not a decent brim. For smaller production items you're going to fit more items per print.

Another way to look at it is you're never going to wish you had the smaller bed.
