Calendar shortcode size

Hi, I’ve used the calendar shortcode as such:
[events_calendar long_events=1]

However, I find that the size of the calendar is a little big so I’ve tried to use the width parameter as in the locations shortcode to try to change the size. But I don’t think it takes that parameter as nothing happens.

Here’s my page with the calendar on the right column.

Can you please advise how I can reduce the size of the calendar? Thanks.
