Quantifoil Multi A is a holey support film in which a pattern of various hole sizes, shapes and arrangements are repeated. In addition to circular holes, of three different diameters, there are also different hole spacings, including an oval hole which at high tilt angles would appear round (this would occur at ~ 70°).

The diameters of the circular holes are (about) 1, 1.4, and 2 µm, and the "bar widths" range from 0.5 to 4 µm. The oval holes in the foil have a dimension of 8x2 µm and 4 x 1 µm. By "bar width" we mean the distance covered, on carbon film, from the edge of one hole to the nearest neighbor hole. Take a closer look with better detail.
