Question: what is the average square footage of a master bedroom?
Answer: The master bedroom is likely to feature either a king size bed (1.5 x 2m) or a super king size bed (1.8 x 2m) plus any wardrobe space. An optimum size for a master bedroom would be around 4 x 4m up to around 4.5 x 4.5m (20.25m²).
