Use the `fontsize=xx` inside the `legend` keyword. _e.g._

```julia
lines(1:12, 1:12, figsize=(6,4), legend=(label="data",pos=:LT,box=:none, fontsize=12), show=true)

```

See the [plot docs](https://www.generic-mapping-tools.org/GMTjl_doc/documentation/modules/plot/index.html#plot) (search for `legend and label`). And refer also to the GMT table with the [fonts names](https://docs.generic-mapping-tools.org/latest/cookbook/postscript-fonts.html)
