Math plays an essential role in interior design.1 Consider hiring a professional to design your new home and provide an estimate, only to be surprised by massive cost overruns once the project is complete.

A miscalculation in sizing or budgeting can make a room feel more like a crowded marketplace than a quiet, inviting space, or make you have to reach out your hand every time you want to look out the window. Wouldn’t that be an experience you always want to avoid?Mathematical knowledge is often required of interior designers.You must understand basic geometry and how measurements are calculated to create accurate floor plans.

This is particularly important when designing areas such as kitchens, where accurate calculations are required for effective design and efficiency. The key to good interior design is an understanding of classic and modern structures and geometric principles, as well as an idea of what a given space might have been used for before it was converted into living space.
