Well, there is no difference in size, as much as there is a difference in biota. A pond is characterized as a body of water, which has a photic zone through its entire length/width. In other words, plants could potentially grow all across its surface or below the surface. A lake however is characterized by having an aphotic zone, where the sun cannot penetrate, therefore plants cannot grow all over its surface or below it. This aphotic zone is usually determined by depth. Ponds are typically shallow to allow light to pass down deep enough for plants to survive. There is no standard size for lakes, ponds, bogs, etc. They are usually determined by their composition, both biotic and abiotic. So everyone that said that a lake is bigger is technically wrong, since there are some ponds that can exceed the size of small lakes, but due to the absolute photic zone, it is technically a pond. So, there you have it, I hope that helps!
