Single Grid Squares for Cryo-EM, Different Mesh Sizes, 1000x Scale

1000x scale of various grid square mesh sizes (200, 300, 400). Aluminum foil is approximately to scale for a C or Au foil. See image for original dimensions and scaling. Note that heights are approximate; although mesh height gets thinner as mesh size increases and approximate ranges of mesh heights are known, there are no quantitative measurements available for exact mesh height and/or standard deviation of that height.
