If you say something was 'a tight squeeze', it means you had difficulty doing something because of a lack of time or insufficient space. If something was 'a tight squeeze, it might mean you had just enough time to do it or were at risk of being late or missing a deadline. People using elevators with lots of people in them or using public transport (such as the underground) which is very full might say 'it was a tight squeeze', if they fit in or on a very full bus, tram or metro. Usually, this expression is used when the outcome was positive, or when the person using the expression succeeded in their task. This expression is more likely to be used in casual contexts.
