The universe have been expanding since the big bang. After the first 200 seconds after the creation of the universe, the universe was the size of galaxy. Now how much the universe size is nobody can measure It is also said that a lot of matter and antimatter have been destroyed since then.
In the first few moments of the universes creation, particles called quarks were formed. They soon fused to create the first atoms called hydrogen and helium. Larger atoms such as beryllium, oxygen and carbon were formed by the nuclear reactions inside stars. Even bigger atoms were formed due to the shock waves inside the stars such as tungsten or osmium.
But all this took a lot of time to happen.

We know how big it is now, we know how old it is, and we know the rate of expansion. Its like rewinding a movie that you started in the middle. We just rewind the known universe as it is now. We dont know how big it was before the big bang but we know how big it was at the initial kaboom.
