vba How big is a worksheeet

As you know, a worksheet cell can hold a constant value or the result of a formula. The value may
be a number, a date, a Boolean value (True or False), or text. Every worksheet also has an invisible drawing layer, which lets you insert graphic objects, such as charts, shapes, SmartArt,
UserForm controls, pictures, and other embedded objects.
You have complete control over the column widths and row heights — in fact, you can even hide
rows and columns (as well as entire worksheets). You can specify any font size, and you have
complete control over colors. You can display text in a cell vertically (or at an angle) and even
wrap it around to occupy multiple lines. In addition, you can merge a group of cells to create a
single larger cell.
