Furniture: Consider the size of your bed, dressers, nightstands, and any other furniture you plan to include in the space. You'll need enough room to comfortably move around and access all of your belongings.

Space for Additional Features

In addition to the bedroom itself, you may want to include features like a walk-in closet, a seating area, or an en-suite bathroom. These will require additional square footage.

For example, a walk-in closet typically needs to be at least 7 feet deep and 3 feet wide to accommodate hanging clothes and shelves. A seating area might require an additional 100-200 square feet, depending on the size of the furniture you plan to include.

Budget and Home Value

Larger master bedroom suites can significantly increase the value of your home, but they also come with a higher price tag. Be sure to consider your budget and the potential return on investment when determining the size of your master bedroom suite.

According to Remodeling Magazine's 2021 Cost vs. Value Report, a mid-range master suite addition can recoup around 63% of its cost at resale, while an upscale addition can recoup around 54%.

Ultimately, the size of your master bedroom suite is a personal decision that depends on your lifestyle, preferences, and budget. By understanding the average sizes and factors to consider, you can make an informed decision that will enhance your living space and add value to your home.
