# #StackBounty: #symbols #mtpro #math-fonts #newtxmath Problem with scale of imported glyphs

### Bounty: 50

Traying to obtain the Times 4-Line Mathematics used in old math books of Springer (and many other scientific textbooks) I downloaded the `mtpro2 lite` package. However, this package doesn’t include a `varg` option, like `newtxmath`, as far as I know.

So, following Egreg’s answers and, I have imported the glyphs `varg`, `varv` and `varw` to my document.

The problem is that it seems they are quite smaller than the `mtpro2` fonts:

The following image corresponds to the Springer’s book of Morris W Hirsch Differential Topology:

Certaily, the glyph looks different, but the main problem I see is that the `varg` and especially `varv` seem quite smaller; in my opinion the \$x\$ is quite taller.

Do you know a way to correct that? I thought in using the package `newtxmath` instead of `mtpro2` and import the `z` glyph (with the upright base). The problem is that I would have to change also the italic z in normal text.

Here I attach the `mwe`:

``````documentclass{article}
usepackage[scaled=0.92]{helvet}    % set Helvetica as the sans-serif font
renewcommand{rmdefault}{ptm}      % set Times as the default text font
usepackage[lite,subscriptcorrection,slantedGreek,nofontinfo]{mtpro2}
