Constraints on the lifetime and width of the Higgs boson are obtained from $\mathrm{H} \to \mathrm{ZZ} \to 4\ell$ events using data recorded by the CMS experiment during the LHC run 1 with an integrated luminosity of 5.1 and 19.7 fb$^{-1}$ at a center-of-mass energy of 7 and 8 TeV, respectively. The measurement of the Higgs boson lifetime is derived from its flight distance in the CMS detector with an upper bound of $\tau_{\mathrm{H}}$ lower than $1.9 \times 10^{-13}$ s at the 95% confidence level (CL), corresponding to a lower bound on the width of $\Gamma_{\mathrm{H}}$ larger than $3.5 \times 10^{-9}$ MeV. The measurement of the width is obtained from an off-shell production technique, generalized to include anomalous couplings of the Higgs boson to two electroweak bosons. From this measurement, a joint constraint is set on the Higgs boson width and a parameter $f_{\Lambda Q}$ that expresses an anomalous coupling contribution as an on-shell cross-section fraction. The limit on the Higgs boson width is $\Gamma_{\mathrm{H}}$ lower than 46 MeV with $f_{\Lambda Q}$ unconstrained and $\Gamma_{\mathrm{H}}$ lower than 26 MeV for $f_{\Lambda Q}=0$ at the 95% CL. The constraint $f_{\Lambda Q}$ lower than $3.8 \times 10^{-3}$ at the 95% CL is obtained for the expected standard model Higgs boson width.
