Very small indeed. The asteroid belt is very thinly populated with three large asteroids making up over half the bulk of the belt. The total mass of the entire belt is less than 4% of our own Earth's moon.

About 4 billion years ago the asteroid belt may have been (almost) a planet, but was pulled apart by gravitational forces ( mostly Jupiter ) or broken up by impacts. From the speed/orbit of the asteroids we can calculate that the size of any planet would be about the size of Pluto - certainly less than the size of the moon. The largest asteroid is Ceres, which has a diameter of 900km and contains almost half the mass of the asteroid belt.

I've read that the mass of asteroids (including the ones wandering near Earth) is probably enough to form a planet a little smaller than Mercury.

purely positioned; The sunlight began to heat that gas & airborne dirt and dust cloud earlier if had thoroughly condensed into the planets. the warmth and image voltaic wind drove lots of the gasses and vapors out of the section interior the present asteroid belt. The gas giants caught even if of the indoors gadget hydrogen, methane and ammonia that did not blow away. What volatiles the indoors planets have, they possibly trapped formerly. Even on the instant Venus Earth and Mars are nonetheless dropping environment to image voltaic wind.

If we stuck all the asteroids together how big would the new planet be?
If all the materials of all the asteroids were squashed up into one planet it would be smaller than our moon.

Very small, the "asteroid belt" is pretty sparce. The answer is about 20 times smaller than the moon

Asteroids are either revolving around a cosmic body or speeding rocks or dust particles through space. It is near impossible to bring such speeding bodies togather and make them stick togather to form a planet. we do not yet have knowledge as to how to fuse such astroids. Hence one has to only dream of the size.

Somewhere between the size of Mercury and Mars considering the distance from the sun and the number of them to form a "belt" in their orbital path.

As Gregg D said, smaller than the Moon.

About the size of earth. I know because we used to live on that planet before we blew it up...
