🔍 What Is the 'Size Chart' Label?

When reviewing H2 headings in Otto AI, you may notice some of your original headings are flagged with a label that reads Size Chart. This is not a reference to text content inside your headings. It is a UI metric indicator — a classification label Otto AI uses to describe the character length category of your H2 heading.

In other words, Otto AI groups H2 headings into named length tiers so you can quickly see whether a heading is too short, well-sized, or too long — without counting characters manually. Size Chart is the name of one of those tiers.

📊 What Do the H2 Length Tiers Mean?

Otto AI evaluates each H2 heading on your page and assigns it to a length category based on its character count. These categories act like a sizing scale:

• Too Short — The heading is likely too brief to be descriptive or keyword-relevant.
• Size Chart — The heading falls within a mid-range length that Otto AI has flagged for review. It is not necessarily wrong, but it sits outside the recommended optimal range and may benefit from adjustment.
• Optimal — The heading length aligns with SEO best practices for H2s.
• Too Long — The heading is likely too lengthy, which can dilute focus and hurt readability.

When you see Size Chart next to many of your original H2s, it means those headings share a similar character-count range that Otto AI considers worth reviewing — not that the words "Size Chart" appear anywhere in your content.

🗺️ Where to Find H2 Length Metrics in Otto AI

1. In the left sidebar, click OTTO SEO, then open SEO Automation.
2. Select the project or page you want to review.
3. Navigate to the On-Page or Content Audit section within Otto AI.
4. Look for the H2 Headings panel. Each heading listed will display its current length label — such as Size Chart, Optimal, Too Short, or Too Long — alongside the original text of the heading.

The label column describes the size classification, while the adjacent column shows the actual heading text from your page. These are two separate pieces of information.

✅ What Should You Do When H2s Are Labeled 'Size Chart'?

Seeing Size Chart on multiple headings is a signal to review those H2s for length, not a content error. Here is how to approach it:

• Check the character count — Otto AI may display the exact character count next to the label. Compare it against the recommended optimal range shown in the panel.
• Decide whether to adjust — If a heading is clear, descriptive, and relevant, a minor length adjustment may be all that is needed to move it into the Optimal tier.
• Use Otto AI's suggestions — Where available, Otto AI will offer a recommended rewrite. You can accept, edit, or dismiss the suggestion depending on your content strategy.
• Prioritize high-traffic pages first — If many pages show the Size Chart label, start with pages that receive the most organic traffic for the greatest SEO impact.

💡 Quick Summary

• Size Chart is a length classification label in Otto AI's H2 metrics — not text found in your headings.
• It indicates the heading's character count falls in a range that Otto AI recommends reviewing.
• The fix is a length adjustment, not a content rewrite, unless the heading also has separate content issues.
• You can find these labels under OTTO SEO in the left sidebar, inside SEO Automation.
