Across the sites I measured, more headlines are set light or regular than bold. Here is why scale beats weight — and how to use it.
There is a reflex in most people who are new to design: to make something feel important, make it bold. Bigger and heavier. It feels intuitive, and it is almost always wrong. When I measured the headlines of hundreds of the best sites on the web, the single most common weight was not bold at all.
Looking at the sites where I could read a clean H1 weight, the largest group sits at light or regular weight (400 or below) — more than the medium group and more than the bold group. Meanwhile the median H1 size is 60px, and the biggest reach well past 200px. The pattern is unmistakable: these headlines get their authority from size, not from weight.
A heavy headline at a modest size shouts to be noticed. A light headline at a large size does not need to shout — it is simply unavoidable. It also reads as calmer and more expensive, because heaviness reads as effort and lightness reads as confidence. The same word set at 64px/400 and at 32px/800 sends completely different signals about the brand behind it.
Large light type has one failure mode — at big sizes the default letter-spacing looks loose and accidental. The fix is negative tracking, and the best sites know it: 85% of the headlines I measured use negative letter-spacing. It is the quiet detail that separates a considered type system from a default one, and I gave it its own note.
My default headline recipe changed completely. Instead of reaching for 700 weight, I start at 400–550, push the size up until the line has presence (60px and up on desktop), and pull the tracking negative until it feels intentional. Bold is now a deliberate exception for a specific tone — not the reflex.
If you build with AI tools, this is worth putting in your prompt explicitly, because models default to bold: "H1 at 64px, weight 450, letter-spacing -1.5px." Vague instructions get you the average; the average is bold. See what top sites actually use for the fuller typography picture.
