How do you split rent fairly when rooms are different sizes?
Measure each bedroom in square feet and calculate each person's share as their room's sq ft divided by total sq ft. Then apply that percentage to the rent. A 200 sq ft bedroom in a 500 sq ft total bedroom space pays 40% of rent. Add a premium (10–20%) for rooms with features like en-suite bathrooms, walk-in closets, or private outdoor access.
