The lower and upper limits of the total cross section (σtot) at the projected FCC-hh have been estimated. A lower limit has been estimated using dispersion relations in combination with recent LHC data of σtot and the ρ-parameter. The upper limit has been estimated using the standard ln2(s) evolution of σtot. Some models giving values in between those limits are also discussed.
