We study superconducting microtraps with rectangular shapes for cold atomic gases. We present a general argument why microtraps open if brought close to the surface of the superconductor. We show that for a given width of the strips there exists an optimal thickness under which the closest distance of the microtrap from the superconductor can be achieved. The distance can be significantly improved if the edge enhancement of the supercurrent near edges and corners is exploited. We compare the numerical calculations with results from conformal mapping and show that conformal mapping can often give useful approximate results.
