Exotic and conventional mesons from lattice

Recent results on meson spectroscopy from lattice QCD are reviewed. The emphasis is on interesting states near thresholds like $Z_c^{+}(3900)$, $X(3872)$ and $D_{s0}^{\ast }(2317)$. Another focus is on the meson resonances in light, strange and charm sector, where the resonance masses as well as the strong decay widths are extracted from the lattice.
