Detect the discrepancy in measurement


My room has a square window of 4 feet across and 4 feet down. I decided to get only half the area of the window painted. Even after the painting I found that the clear part of the window still remained a square and still measured 4 feet from top to bottom and 4 feet from side to side.
How is it possible?

    Though it does not leave the clear area 4′ x 4′, however does measure 4′ from top to bottom and from side to side.
