The most relevant quantity is the black hole's mass. Note that the black hole's diameter (the diameter of the event horizon, really) is directly proportional to its mass. The largest galactic black holes known seem to be around 20 billion solar masses. Check the Wikipedia "List of most massive black holes" for more details. Note that the mass of some of these black holes is not very well-known.

What is the largest known black hole?
due to the nature of black holes(whether they are high energy or high mass) it is not easily determinable how big a black hole is volume wise. most theories point to a Singularity Principle which means all of the mass within a black hole is packed into an extremely high density point which cannot be given a volume due to its extremely small size.
Where is the largest black hole in the universe and how big?
The largest black hole known is located in the center of galactic cluster PKS 0745-19, which is about 1,300,000,000 lightyears from Earth. This black hole has an approximate upper mass of 40,000,000,000 solar masses, where 1 solar mass is the mass of the Sun. If placed in the center of the Solar System, its event horizon would reach just past Sedna, about 789au (1 au is about the distance frm Earth to the Sun, or 149,597,871 kilometers).
How big is the closest black hole?
The closest known black hole (others that are closer to us may still be discovered) is at a distance of 3000 light-years. Its mass is estimated to be about 11 solar masses.
How big is Neptunes Black hole?
There is no black hole on Neptune. Neptune is a planet in our solar system known for its blue color and is the eighth planet from the Sun. Black holes are incredibly dense regions in space with a gravitational pull so strong that not even light can escape.
What was initially inside the big black barrel?

Can a black hole destory the galaxy?
No. No black hole is big enough to do that.
Can your universe just be at the end of a black hole and can the big bang just be the birth of that black hole?
Actually one interpretation of the big bang is as a white hole, the inverse of a black hole.
Will a black hole destrow earth?
A black hole can,but it is very rare for a black hole big enough to swallow Earth.

What happened when two black hole met?
both of the black hole will join together as one big black hole. they can either have a direct hit or both spin, twirling into each other until it create a new super big black hole.
How big is the closest black hole?
The closest known black hole (others that are closer to us may still be discovered) is at a distance of 3000 light-years. Its mass is estimated to be about 11 solar masses.

What object is the largest?
If you mean in the solar system, then the answer is the sun. Jupiter and Saturn are also some big masses in the solar system. In the galaxy, the largest object is probably the black hole in the center.
Was the big bang a black hole?
No. The Big Bang was an event, not a material thing. (There are plenty of other ways in which it is utterly unlike a black hole as well.)
How big and how long is the black hole?
The size of a black hole is simply a function of its mass (radius being twice the gravitational constant times the mass, divided by the square of the speed of light). There is no upper or lower limit for this, so black holes can be microscopic or gargantuan. Their shape is roughly spherical so the distinction of "length" versus breadth or height might not have much meaning. The largest known to date is a giant supermassive black hole about 11 times the size of the orbit of Uranus.
Will the big bang make a black hole?
no black holes are stars
