My general rule of thumb:

• font-sizes = rem
• padding and margin = em
• widths = px or em or %

For width, percentage is very common, whereas either pixels or em work well for set sizes, like when setting a min-width or max-width. If you stick with pixels here, you'll be fine :)

REM vs EM: https://zellwk.com/blog/rem-vs-em/

• Size in em if the property scales according to its font-size
• Size everything else in rem.
