The map of The Elder Scrolls IV: Oblivion is approximately 41 square kilometers (about 16 square miles) in size. Including its two DLC expansions, the total explorable area increases by another 10 square kilometers (4 square miles), making the full map around 51 square kilometers (20 square miles) in total
. To put this in perspective with other Elder Scrolls games:
- Skyrim's map is slightly smaller, estimated at around 37 to 40 square kilometers (about 15 square miles), but it has more verticality due to mountainous terrain, which affects how large it feels to players
- Morrowind's map is much smaller, roughly 16 square kilometers in total size, making it the smallest of the main Elder Scrolls titles
- Elder Scrolls Online is vastly larger, spanning roughly 400 square kilometers across multiple zones, but it is an MMO with a different map structure
- The original Elder Scrolls: Arena is technically the largest, covering the entire continent of Tamriel, but its size is more theoretical due to looping terrain mechanics
In summary, Oblivion's map is one of the larger single-player Elder Scrolls maps, slightly bigger than Skyrim's in flat area but less vertically complex
