Answer
To change the text size for objects, choose from the menu bar. All object data (descriptions, IDs, dates, float, etc.) will change proportionally, and for every object, selected or unselected, on the canvas (excluding text boxes and annotations).
To change the text size for the calendar strips, click from the menu bar and choose the Formatting tab. Adjust the value next to Strip Text Size. The Canvas may also be magnified through the zoom function, which will enhance readability even more.
