Information on retail mall sizes in the U.S. is generally proprietary information. There are merchant and real estate associations that have web sites offering such information…but only for a fee. After an exhaustive search I was able to locate the site shown in the first reference. It provides for free the information you asked for, and much, much more.

“Percentile” is a value for a variable below which a certain percent of observations fall. In ranking the 8 largest malls in Pennsylvania there would be 7 malls smaller than the largest. Since there are 8 values in the list, each value’s position in the ranking is 12.5% higher or lower than its immediate neighbor. So for the largest mall, one could say that it occupies the 87.5 the percentile, meaning that 87.5 % of the values (7 of the malls) fall below its value.

Here are the malls, ranked in descending order, with the square footages (in millions) and percentiles for each mall:
