Mihai Chelaru's answer presents a way to do more than just adjust the sidebar's font size. This, however, comes with a price of a bit of fiddling, possibly more than you'd be ready for, if the only thing you were interested in was the simple act of changing the sidebar's font size. So here's a simpler solution.

Just zoom the whole VS Code's UI in or out with CTRL++ or CTRL+- respectively and than adjust font sizes we do have control over in settings.json file, i.e.:

• editor.fontSize,
• editor.suggestFontSize,
• markdown.preview.fontSize,
• terminal.integrated.fontSize

so everything matches. That's it.
