The idea of bordered magic squares is well known in the literature. In this work, bordered magic squares are constructed in such a way that the final magic sum of each bordered magic square is 2021. The work is for the orders 3 to 26. The work include fractional and decimal numbers entries having positive and/or negative signs. In some cases, the sum-magic sums lead us to Pythagorean triples. It happens with the even order magic squares starting from order 10, such as, orders 10, 12, ..., 24 and 26.
