In the paper, the values of the thermodynamic critical field (H_{C}) for francium have been calculated. It has been assumed the wide range of the pressure: p∈ ⟨7.2; 14⟩ GPa. The analysis has been performed in the framework of the strong-coupling formalism. It has been predicted that the value of the ratio H_{C}(0)/√ρ(0) increases with the increasing pressure from 3.08 meV to 5.84 meV, where ρ(0) denotes the electron density of states at the Fermi level. The dimensionless parameter T_{C}C^{N}(T_{C})/H²_{C}(0) is smaller than in the BCS theory and decreases with pressure from 0.150 to 0.141. The symbol T_{C} represents the critical temperature and C^{N} is the specific heat for the normal state.
