GIMP brush size can't be size 2 or size 4

This is driving me crazy...

I can select a brush size of 1 pixel, and it's fine. I can select a brush size of 3 or 5 pixels, also fine.

But when I set the size to 2 or to 4 pixels, GIMP will use a brush size of 3 instead???

Depends which brush you use. The 1. Pixel wants to be 3 pixels, but the Pixel (1x1 square) works for 2px:

Theses two brushes are "parametric" brushes (their outline is defined a bit like a path). You can also define a bitmap brush:

Create a 2x2 image
Fill with black
Either:
- Export as .GBR in one of your brushes directories, and select it in the brush list
- Copy to clipboard, and use the Clipboard mask brush (the Clipboard mask brush assumes the Foreground color, the Clipboard image brush keeps the color it was created with)

Thank you. Somehow, it is a lot harder to draw with that brush thuogh. E.g. holding SHIFT for straight lines often still makes lines that are not fully straight. It also often misses pixels.

Yes, because its center is not centered on a pixel but between pixels. You can use a non-parametric brush, see augmented answer.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
