Oh my god. That may be the best answer I've ever seen in a forum. You researched mouse craniofacial measurements. That. Is. Fantastic.

Er... What about *voles?*

Off to go Google THAT....

I haven't tried it but I did a Google search to find mouse measurements.
The most relevant page I found was this one that shows the
measurements of mouse skulls.

http://craniofacial.jax.org/characteristics.html

In the measurements this guy made, the minimum height and width of an 8
week old mouse of the types he measured was a female of one of the types
that appeared to me (by subtracting the +/- from the average) to have a
skull height of around 8.6 mm and a width of around 9.7 mm, with most
mice being a bit larger than that.

Maybe something else in the mouse is more limiting than the skull size,
though they seem to be pretty good at squeezing their bodies into small
spaces.

1/4 inch = 6.35 mm. Could a mouse get through that?

Maybe one younger than 8 weeks could. Maybe a strong one that could bow
out the wire a bit could. Maybe a smart one that found an irregularity
in the mesh could.
