## Common mistakes

- **Odd tick values** Ticks at 13.7 and 27.4 are hard to read. Use round values.
- **Ticks that crowd** At small sizes, show fewer ticks instead of smaller labels.

## Questions

### How many ticks should an axis have?

Three to six, depending on the size.

### Why do ticks thin out at XS?

Each size is laid out again, so labels stay readable instead of shrinking.
