The study focuses on out-of-plane deformations of plates folded according to the Miura pattern. Such deformations arise due to the influence of the pattern’s geometry and the interaction between the facets. We designed 27 patterns with different combinations of geometric parameters, manufactured them using laser cutting and manual folding, and measured them with an optical 3D scanner. Based on the obtained data, we determined the discrete Gaussian and geodesic curvature and, using the Gauss–Bonnet theorem, calculated the continuous Gaussian curvature of individual surfaces. We found that all patterns exhibit global negative (saddle-shaped) curvature and that the deformations are most influenced by the angle $\alpha$ the side length a, while the influence of parameter b is almost negligible.
