Embodiments of the present technology provides universal panels and structures made from the same. The panels are formed using specific ratios for width and length of the panels, which are related to ratios of aperture spacings for the panels. These ratios are used to ensure that panels can be used in a universal manner to form walls, roofs, and doors. Additionally, the universality of the panels reduces the likelihood that installation errors will occur when building structures with these panels. Installation errors can deleteriously affect the structural integrity of the the resulting structure.
