Hand‐sized gecko‐inspired adhesives with reversible force capacities as high as 2950 N (29.5 N cm ‐2 ) are designed without the use of fibrillar features through a simple scaling theory. The scaling theory describes both natural and synthetic gecko‐inspired adhesives, over 14 orders of magnitude in adhesive force capacity, from nanoscopic to macroscopic length scales.
