How do I find the square footage of my house?

D. Hendy asked:


I’m just curious to know, is there a simple way to find how many square feet are in my house?

By the way, my house has alot of sides, and I don’t want to measure them and multiply them, I was just wondering if there was a simple way to find out.

And I don’t have the blueprints to the house or anything like that…
