We show that a uniform differential pressure load $\\Delta P$ over elliptical regions of free-standing graphene yields measurable deviations from hydrostatic strain conventionally observed in radially-symmetric microbubbles. The top hydrostatic strain $\\bar{\\varepsilon}$ we observe is estimated to be $\\approx0.7\\%$ for $\\Delta P = 1\\,{\\rm bar}$ in graphene clamped to elliptical SiN holes with axis $40$ and $20\\,{\\rm \\mu m}$.
