A common kitchen should take 10-15% of the total floor area. So, if you live in a big house, your kitchen should have an area of about 240-360 sq. ft.; usually, this is an open cooking-and-dining space. An average small kitchen, on the other hand, is less than 70 sq. ft. in area, while a mid-sized kitchen in an Indian house measures 100-200 sq. ft. Unless you have cooked in all of these, you can't determine which is the best suited for you.
