To change the size of the form, put the pointer on the form border and drag.
The form is resized.
To resize a label, click it to select it, and then drag one of the sizing handles (any black box except for the bigger box in the upper-left corner) until the label is the size you want.
If the contents of a field name or field entry are not completely displayed in a form (a common occurrence when you use a row and column?style layout), you can resize the control, be it the field's label control, text box control, or both. In addition, you can resize the entire form as needed to make room.
The label is resized (here, made smaller).
To resize a text field, click it to select it, and then drag any of the sizing handles (except for the bigger box in the upper-left corner) until the text field is the size you want.
The text field control is resized (again, made smaller).
Click the Save button on the Standard toolbar in the main Access window to save the change to the form.
No Automatic Adjustments
Access does not make an automatic adjustment if one control overlaps another. You need to manually move and resize the controls so that they don't overlap.
