Designers often forget the small version of a logo. It is fine if your mark is complex, detailed, long, or tall. What matters is thinking ahead about how it behaves in tight spaces.
The simplest example is an app icon or social avatar. Simply scaling down while holding Shift is not an option. It becomes unreadable mush.
So alongside the main logo, plan a small version. It may differ significantly from the full one — and that is normal.
Again, printing helps: a designer sets minimum logo size at 20 mm while viewing it on a 30-inch screen at 300% zoom. Print immediately shows problems at that size.
