What is the standard size of a bedroom?

Since many of us grew up in a 10×10 bedroom or smaller as kids, sometimes we think we want our kids to have bigger bedrooms, or sometimes we even want them to be the same size as our master bedrooms. Most of our time in the bedroom is spent sleeping and unaware if the room is 10×10 or 16×16. Lakeside likes to look at room sizes by square footage. For master bedrooms, we feel 200 to 260 sq. ft. is a nice size. If you want a sitting area or a coffee bar in your master suite (yes we have had a coffee bar requested in the bedroom) then 260 to 320 sq. ft. would work. For secondary bedrooms 120 to 150 sq. ft. works nicely with the average being around 130 sq. ft.
