It fits around 504 Dvds.  We did find that the shelf holes were in the wrong place to be able to evenly fit the shelves for Dvds if the instructions were followed, so turned the bookcase upside down, exchanging the top and bottom panels.  With the 15.1cm distance between the first hole and edge at the top of each side panel section the hole spacing was perfect for 8 evenly spaced shelves.  We are now ordering another unit for our remaining Dvds and Cds.
