Headline Length — How Many Characters Should Your Headline Be?

<h2>Why Headline Length Is a Tactical Decision</h2> <p>Headline length isn't about preference. It's about platform constraints.</p> <p>Google displays 50-60 characters before truncating your title tag. Email clients show 40-70 characters depending on the platform. LinkedIn shows 140 characters before the "See more" cutoff.</p> <p>If your headline exceeds these limits, it gets cut. The cut often removes the most important part — the promise or the call to action.</p> <p>Understanding length constraints is the difference between headlines that display fully and headlines that get truncated.</p> <h2>Platform Display Limits</h2> <h3>Google SERP</h3> <p>Google displays approximately 600 pixels of title tag space. That translates to 50-60 characters on average.</p> <p>The actual number depends on your letter combinations. Capital letters take more space. Wide letters like W and M consume more pixels than narrow letters like I and l.</p> <p>Google announced in 2024 that longer titles might be shown more frequently, but the practical limit remains around 55 characters for reliable full display.</p> <p><strong>Target:</strong> 50-55 characters for Google titles.</p> <p><strong>Test your headlines:</strong> Use a character counter that accounts for pixel width, not just character count.</p> <h3>Meta Descriptions</h3> <p>Meta descriptions don't directly affect rankings. They affect click-through rates. A well-written meta description that displays fully outperforms a truncated one every time.</p> <p>Google typically shows 155-160 characters of meta description text.</p> <p><strong>Target:</strong> 150 characters for meta descriptions.</p> <h3>Email Subject Lines</h3> <p>Email clients vary significantly in how much of your subject line they display:</p> <ul> <li>Gmail desktop: ~70 characters</li> <li>Gmail mobile: ~40 characters</li> <li>Outlook desktop: ~60 characters</li> <li>Apple Mail: ~65 characters</li> <li>Yahoo Mail: ~50 characters</li> </ul> <p><strong>Target:</strong> 40-50 characters for email subject lines to ensure full display across all platforms.</p> <h3>Social Media</h3> <ul> <li>LinkedIn: 140 characters before "See more"</li> <li>Twitter/X: 280 characters (but display is limited in feeds)</li> <li>Facebook: 477 characters before truncation</li> </ul> <p><strong>Target:</strong> Aim for under 100 characters for social headlines that display well in mobile feeds.</p> <h2>How to Test Length</h2> <h3>Step 1: Count Characters</h3> <p>Start with a simple character count. Most word processors and text editors will show this in the status bar.</p> <h3>Step 2: Estimate Pixel Width</h3> <p>Character count alone isn't enough. A 50-character headline with all capital letters takes up more space than a 50-character headline with all lowercase.</p> <p>Use a pixel-width estimator tool or preview your headline in a browser.</p> <h3>Step 3: Preview on Platform</h3> <p>The only way to know if a headline displays fully is to see it on the actual platform. Google Search the title tag. Open your email in Gmail and Outlook. Check how it appears on mobile.</p> <h3>Step 4: Identify Cutoff Points</h3> <p>When headlines get truncated, the cut typically happens at the end of a natural phrase or word. Plan for truncation by putting the most important words at the beginning.</p> <h2>Common Length Mistakes</h2> <p><strong>Mistake 1: Writing headlines before checking limits.</strong> Write first, then trim. Trying to write within constraints from the start leads to overly cautious, short headlines.</p> <p><strong>Mistake 2: Ignoring mobile.</strong> Desktop email clients show more characters than mobile. If your audience reads email on mobile (most do), your subject line needs to work on small screens.</p> <p><strong>Mistake 3: Overestimating space.</strong> "Headline" can be 200 characters. "Google title tag" is 50-60 characters. Always write for the smallest display.</p> <p><strong>Mistake 4: Trimming the wrong end.</strong> When trimming headlines to fit, writers often cut from the front. But the beginning of the headline is the most important part. Cut from the end to preserve the hook.</p> <h2>Length by Use Case</h2> <table> <thead> <tr> <th>Use Case</th> <th>Target Length</th> </tr> </thead> <tbody> <tr> <td>Google title tag</td> <td>50-55 characters</td> </tr> <tr> <td>Meta description</td> <td>150 characters</td> </tr> <tr> <td>Email subject line</td> <td>40-50 characters</td> </tr> <tr> <td>LinkedIn post</td> <td>100 characters</td> </tr> <tr> <td>Landing page H1</td> <td>8-12 words</td> </tr> <tr> <td>Ad headline</td> <td>30-40 characters</td> </tr> </tbody> </table> <h2>Do This Now</h2> <ol> <li>Pick one of your key landing pages.</li> <li>Check the current title tag length.</li> <li>Preview how it displays in Google search results.</li> <li>Trim until it displays fully without truncation.</li> <li>Check the same for your email subject lines.</li> </ol> <p>Length is a tactical constraint.
