The Elder Scrolls IV: Oblivion Remastered has a file size of approximately 120 to 125 GB, which is about 26 times larger than the original 2006 game that was only 4.6 GB. This significant increase is due to the game being rebuilt with Unreal Engine 5, featuring much higher resolution textures (4K compared to the original 1K), extensive visual overhauls, and inclusion of all original DLCs. The remaster's size places it among the largest games by install size, roughly around seventh place in some lists

. In terms of map size, Oblivion Remastered retains the original's explorable area of about 41 square kilometers (16 square miles) for the base game, with an additional 10 square kilometers (4 square miles) added by the included DLCs
