In the UK that is a 'large' glass of wine. The NHS¹ calls 175ml 'standard' (slightly more than usual) and 125ml 'small'.
For the UK this is all not that relevant, because there the concept of the 'alcohol unit' is much more ingrained and used in public health campaigns, so you would work with those. E.g., with the recommended upper limit of 14 alcohol units, you could drink a standard glass of wine (175ml) six days of the week (12.6 units), or have a bottle of lager six days of the week and a pint of Guinness on Saturday (13.2 units).
