The width of a drop-down box in a cell is determined by the width of the cell itself. Therefore, to change the width of the drop-down box, you need to adjust the width of the cell that contains the drop-down list.
This is not the case for me. I created a column in a table that was very wide by default. First, I added data validation to the column, and then I changed the width of the column, but the width of the data validation drop-down did not change and is still inappropriately wide. No change to the width of the column results in any change to the width of the drop down.
