The logos that hold up for decades share something that has nothing to do with style. They're built on clear structure.
When I analyze marks that have remained relevant for twenty, thirty years, the common thread isn't minimalism or complexity or any particular aesthetic era. It's that the underlying geometry is resolved. The proportions are intentional. The relationship between the mark and the type is considered. Nothing is arbitrary.
Arbitrary decisions are what age logos. A typeface chosen because it was popular. A color chosen because the client liked it that week. A shape chosen because it felt modern. These decisions are made relative to the current moment, which means they expire with it.
Structural decisions don't expire. If the letterforms are custom and the spacing is precise and the mark reduces cleanly to a single color at any size, those qualities don't become dated. They just become familiar — which is exactly what a brand needs.
When I start a logo project, the first question isn't "what should this look like?" It's "what does this need to do, and for how long?" That question changes every decision that follows.
