The effect of the granule size distribution on the percolation threshold in "metal-dielectric" granular alloys has been studied by numerical simulation. In the model alloy under consideration, metal granules have two characteristic dimensions, $l$ and $L$, $L>l$. The percolation threshold substantially increases as the $L/l$ ratio grows, both for the 2D and the 3D case, and tends to saturate at high $L/l$ values. The calculation results offer an explanation of high percolation thresholds observed for most granular alloys.
