Questions

How big is the Small lm399 PCB?

It measures 767.1 × 471.2 mm and has 4 copper layers, 1.6 mm thick.

What parts does the Small lm399 use?

293 parts, built around the OP07. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Small lm399 KiCad files?

From the cellularmitosis/small-lm399 repository on GitHub, at the commit this page was made from: the board is kicad/small-lm399.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Small lm399 design in my own project?

Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
