Delaware's total area is only 1,982 square miles. It is 96 miles long and ranges from 7 miles wide to 35 miles wide. Delaware is so small, in fact, that it only has three counties.

How big is Delaware by population?
As Delaware is quite small geographically, it should come as no surprise that the state also has a relatively small population. According to the US Census Bureau, Delaware had an estimated population of 989,948 in 2020. This makes it the 45th most populous state in the country. However, Delaware is quite densely populated. It is the fifth most densely populated state in America.
Delaware's largest city is Wilmington. It has an estimated population of around 70,000, making Delaware one of only a handful of states that does not have at least one city with a population of over 100,00. However, Wilmington is considered to be part of the Philadelphia metropolitan area, which has a population of over 6 million people.
