A couple of days ago both the week and month calendar views added a new pull down that allows you to easily set the size of the calendar boxes.

 

The pull down appears in the title area right next to the calendar title.

 

Just click on the pull and choose a one of the convenient settings (small, medium, large) and you'll have your calendar boxes immediately adjusted. This makes it extremely easy to adjust the box sizes - for instance, to make them small so you can see an entire month in your browser window for an overview of your schedule.  But then you could immediately set them back to be much larger to allow you to make detailed entries into any of the day boxes.  Remember - you can type a ton of free format text into each day box, making Keep and Share calendars the ultimate in free format calendaring.

 

As always, when in month view if you click on the calendar day name (e.g., 'Tuesday' or 'Sunday') the calendar will 'zoom in' and display that day in week view, giving you larger boxes to work with.
