Below is a list of the largest known nebulae so far discovered, ordered by actual diameter. This list is prone to change because of inconsistencies between studies, the great distances of nebulae from our stellar neighborhood, and the constant refinement of technology and engineering.
Caveats
[edit]Nebulae have no standardized boundaries, so the measurements are subject to revision. Lastly, scientists are still defining the features and parameters of nebulae. Because of these rapid developments and adjustments, this list might be potentially unreliable.

Notes
[edit]- ^ distance × sin( diameter_angle ) = 1,895 ly
- ^ distance × sin( diameter_angle ) = 1,520 ly
- ^ Those measurements are based on an apparent diameter of 480 arcminutes (') plus an assumed distance of 1.5 kpc and the current distance of VY CMa which is about 1.17 kpc as the nebula is sometimes found to have the same distance as VY CMa.
