The High-Luminosity operation of the LHC poses unprecedented challenges for the design of the upgraded trackers of ATLAS  and CMS . The stringent requirements imposed by the high particle density and integrated fluence reduce the phase-space of valid technical solutions, inducing both collaborations to design “all-silicon” trackers. On the other hand constraints and requirements coming for the rest of the detector lead to some different choices, especially for the outer trackers. The main requirements for the two tracking systems are reviewed, discussing the implications for the detector designs and layout, and explaining why some of the technical choices remain different in the two experiments. To conclude, some expected performance figures for the two tracking systems are presented.
