How long should your H1 be?

Short answer: as long as it needs to be to carry one idea — and not a word longer. The real constraint on a headline was never length. It's how many messages it's trying to hold. A long H1 that lands one clear idea will beat a short, clever one juggling four every time. So the better question isn't "how long can my H1 be?" — it's "how many messages is it carrying?" The answer should be one.

The real test for a hero section

Read your homepage hero once. Look away. Write down what you remember.

Most people get almost nothing — because the hero asked them to hold a dozen ideas at once: a market, a technology, three benefits, a workflow, an outcome, a couple of adjectives, and a promise. Faced with twelve competing ideas, a buyer doesn't rank them and keep the best one. They drop all of them.

This isn't a word-count problem. You can carry one idea in forty words or bury twelve in thirty. Good copywriting has always said it plainly: use as many words as necessary, and not one more. The number that decides whether a hero works isn't words. It's messages.

Why abstraction makes it worse

The overloaded hero is almost always an abstract one, too. "Unleash the power." "Seamless, integrated." "Next-generation." A reader can't picture the power of something, can't define seamless, can't see what unleash actually does. Concrete ideas get remembered; abstract ones evaporate on contact. Stack a dozen abstractions above the fold and you've built something no one can repeat back to you — which means no one can repeat it to their boss, either. And in B2B, the person reading your homepage is rarely the person who signs. Your message has to survive being retold by someone else.

The fix is a decision, not shorter copy

Before the design, before the words, you choose the single idea you want to own in the buyer's mind — the anchor everything else hangs off. One clear thing a prospect can carry out of the page and repeat in a hallway. Every other message on the site then earns its place by supporting that one, or it goes.

This is the hardest conversation in a branding project, because your product genuinely does a lot and you want to say all of it. You can't. The buyer's memory won't let you. Choosing one idea feels like leaving value on the table; in practice it's the only way any of the value survives the visit. It's also why strong positioning comes before copy — the headline is downstream of the one idea you've decided to own.

What it looks like when a team actually chooses

Helping a founder with a hundred true things to say pick the one to lead with is most of what we do at the start of an engagement.

• i3systems briefed us to centre "automation" — exactly where every competitor already stood. We moved the whole story one word over, to making work simpler, and landed on a single line the founder said would stay with them for years: "It Gets Simpler." One idea, and ownable.
• 5X came to us mid-pivot — "extremely confused, a hundred things in mind," wanting a complete change of audience. The work wasn't adding messages; it was subtracting to clarity, until the first homepage draft was already "75–80% there."
• Relanto's old site was a list of services. We rebuilt it around outcomes — revenue, growth, cost — and mapped every claim to a real case study. Fewer ideas, each one provable.
• NimbleEdge had tried a cheaper agency and got "a website where every page was independent, with no meaningful customer journey." The homepage was the hard part; once the single core idea was nailed, the rest of the site de-risked itself.

In every case the win wasn't eloquence. It was the willingness to prioritise.

So — how long should your H1 be?

Long enough to carry one idea clearly, and no longer. Stop counting words and start counting messages. If your headline is holding more than one, the length was never the problem.

Your messaging isn't the manual for your product — it's the reason someone decides to pick it up. Choose the one idea. Go all in on it. It's harder than saying it all, and it's the only thing that works. At Everything Design, that decision — the one idea to own — is where every positioning and messaging engagement begins.
