The application relates to the technical field of special glass, and provides a glass substrate, chemically strengthened glass and a strengthening method and cover plate glass. The glass substrate provided by the application comprises the following components in terms of the total mole content of oxides in the glass substrate: SiO2: 58-68%; Al2O3: 7.5-9.2%; Na2O: 11.3-14.5%; K2O: 2.5-5%; MgO: 7.5-10.2%; B2O3: 0-2%; ZnO: 0.1-2%; and WO3: 0.1-4%. The size change rate of the glass substrate provided by the application is less than or equal to 0.015% before and after chemical strengthening. During the chemical strengthening process, the glass substrate needs to be inserted into a holder, and then the glass substrate and the holder are placed in a strengthening salt bath for strengthening. Since the size change rate of the glass substrate provided by the application is small, the holder does not need to reserve a large size change gap, and the risk of glass film falling can be obviously reduced.
