The default built-in font, Boldface, which is loaded at boot-time on a framebuffer (whether genfb or DRM) console is too small as it is 8x16. The other font built into the kernel is Boldface 16x32, and this, if you load it, will give you a console approximating a 80x25 screen--ie. this font is too large. Try it:
$ sudo wsconsctl -f $(tty) -dw font="Boldface 16x32"
The other fonts in /usr/share/wscons/fonts/ are all also small (8x16, 8x10, 8x8), as their extensions indicate.
The solution that is usually advocated to get a reasonable-size font is to a) edit the kernel config, b) add one of the fonts in /usr/src/sys/dev/wsfont/ using directives like options FONT_SPLEEN16x32, and c) then recompile the kernel. But, this is a pain. Simpler to write a program to suck in the fonts and load them into the kernel as needed. This is what the code below does.
Compile, and then run it as follows:
$ ./wsfont list

After you've checked out the fonts available on NetBSD (9.1 shown above), you can write all the fonts into /usr/share/wscons/fonts/ and then load your choice at boot-time via /etc/wsconf.conf:
$ sudo ./wsfont dump /usr/share/wscons/fonts/
$ ls -ltr /usr/share/wscons/fonts/*.fnt

Edit your /etc/wsconf.conf and add lines like these (read the wscons.conf(5), wsfontload(8) and wsconsctl(8) man-pages for details):
font dejavu 12 22 iso /usr/share/wscons/fonts/DejaVu_Sans_Mono_12x22.fnt
setvar ttyE0 font dejavu
setvar ttyE1 font dejavu
setvar ttyE2 font dejavu
setvar ttyE3 font dejavu
You'll easily find the locations where you should add those lines. Check out the QVSS font, where somebody's clearly been having fun.
