When calculating a one-sample t confidence interval, a confidence level of 100% will give the largest interval as it means we are 100% confident that the true population parameter falls within the calculated interval, which will be wider than any other confidence level. However, 100% confidence intervals are practically never used as it implies infinite confidence in the estimate, which is impossible.
