The math is one line: length × width. Ten by twelve is the workhorse bedroom size in post-war houses: 120 square feet that take a queen bed, two nightstands and a dresser without shuffling sideways.

Questions about 10×12 rooms
Is a 10×12 room 120 sq ft including the closet?
The 120 sq ft is the full rectangle, walls to walls, so a closet inside that outline is already included. A closet outside the rectangle adds its own little rectangle on top — add it as a row in the calculator.
How much flooring do I need for a 10×12 room?
Order for 132 sq ft — the area plus 10% waste for cuts. For diagonal or herringbone layouts use 15%, i.e. about 138 sq ft. The flooring calculator turns that into boxes for your specific product.
