Methodology

The Interior Design Giants of Design annual business survey comprises the largest firms ranked by interior design fees for the 12-month period ending Dec. 31, 2024. The listings are generated from only those surveyed. To be recognized as a top 100, Rising, Healthcare, Hospitality, or Sustainability Giant, firms must meet the following criteria: Have at least one office location in North America and generate at least 25 percent of its interior design fee income in North America. Firms that do not meet the criteria are ranked on our International Giants list. Interior design fees include those attributed to:

1. All aspects of a firm’s interior design practice, from strategic planning and programming to design and project management.

2. Fees paid to a firm for work performed by employees and independent contractors who are “full-time staff equivalent.”

Interior design fees do not include revenues paid to a firm and remitted to subcontractors who are not considered full-time staff equivalents. For example, certain firms attract work that is subcontracted to a local firm. The originating firm may collect all the fees and retain a management or generation fee, paying the remainder to the performing firm. The amounts paid to the latter are not included in fees of the collecting firm when determining its ranking. Ties are broken by rank from last year. Where applicable, all percentages are based on responding Giants, not their total number.
