Magnetic skyrmions are knot-like quasiparticles. They are candidates fornon-volatile data storage in which information is moved between fixed read andwrite terminals. Read-out operation of skyrmion-based spintronic devices willrely upon electrical detection of a single magnetic skyrmion within ananostructure. Here, we present Pt/Co/Ir nanodiscs which support skyrmions atroom temperature. We measured the Hall resistivity whilst simultaneouslyimaging the spin texture using magnetic scanning transmission x-ray microscopy(STXM). The Hall resistivity is correlated to both the presence and size of theskyrmion. The size-dependent part matches the expected anomalous Hall signalwhen averaging the magnetisation over the entire disc. We observed aresistivity contribution which only depends on the number and sign ofskyrmion-like objects present in the disc. Each skyrmion gives rise to 22$\pm$2n{\Omega} cm irrespective of its size. This contribution needs to be consideredin all-electrical detection schemes applied to skyrmion-based devices.
