What is the coverage area for one can of paint?

This stuff gets better as you thin it, maintains rich color while coverage is extended. I added 3/4 of a bottle of water to my quart and it easily covered 1 entire sheet of raw plywood 4 x 8ft front and back, and 1/4 sheet of another, as well as several full 8ft length 2 x 4's with this thinning ratio.

I know for me that 2 1/2 cans did a room of 15'4"x13'4"

Valspar Latex Enamel will typically cover approximately 100 square feet per quart. Spreadrate does vary considerable depending on the texture and porosity of the surface to which it is applied.
