To make everything in the spreadsheet larger, i.e. to zoom in, position the mouse in any spreadsheet cell, hold the control key and then roll the mouse wheel upward a few clicks. To make the text smaller, roll the wheel down.
The make the cells wider, position the mouse on the right edge of the Column top header cell and when the sideways arrow cursor appears, left click and hold and drag.
