It's half-height (fits in "slim" desktops, those media center PCs, and in a 2U server without having to turn it sideways/use a riser), and barely longer than the PCIe socket. Phoronix has a picture with a full-height bracket which maybe gives a better point of comparison: https://www.phoronix.com/review/intel-arc-pro-b50-linux
(A half-height single-slot card would be even smaller, but those are vanishingly rare these days. This is pretty much as small as GPUs get unless you're looking more for a "video adapter" than a GPU.)
