Free Code to Text Ratio Checker

What Is the Code to Text Ratio Checker?

A free code to text ratio checker is a tool that measures what share of a page's HTML source is actual visible text, as opposed to markup, scripts and styles. Paste the HTML source and it returns the total size, the visible-text size, the code size, the ratio as a percentage, a band guide, and the visible word count. If you need a code to text ratio checker for an on-page audit, this page gives you the numbers from the source you paste.

What Is It Used For?

SEO auditors use it as one signal in a page audit, especially for thin or template-heavy pages. Developers use it to spot pages where scripts and markup dwarf the content. Bloggers use it to check whether a post page carries enough real text. Theme reviewers use it to compare how much weight different templates add around the same content.

Key Benefits

• Full breakdown — total, text and code sizes in bytes, so you see where the weight sits.
• Ratio percentage — one number for the visible-text share of the page.
• Band guidance — below 10% reads as thin, 25–70% is commonly cited as healthy, so you know where you stand.
• Visible word count — the actual words a visitor could read, not the markup around them.
• Completely free and private — no signup, and nothing you paste ever leaves your browser.

How to Use This Free Code to Text Ratio Checker

1. Open the page in your browser, view its source, and copy the HTML.
2. Paste the source into the box here.
3. Click Check Ratio. The sizes, the ratio, the band guide and the word count appear below.
4. Compare pages on the same site: a page far below its siblings usually has a template or script problem, not a content problem.
5. Click Clear to check another page.

Common Mistakes to Avoid With Code to Text Ratio

• Treating the ratio as a ranking factor. Google's John Mueller said in 2018 that code-to-text ratio is not a direct ranking factor. Use it as a weight and thin-content signal, not as a lever to chase.
• Checking a URL instead of source. This tool cannot fetch live pages, so pasting a URL gives a meaningless result — paste the actual HTML source.
• Padding pages with filler text. Adding words just to lift the ratio makes pages worse for readers. Fix the code weight or write genuinely useful content instead.
• Comparing unlike pages. A checkout page and an article will never share a healthy ratio. Compare similar page types only.
• Forgetting JavaScript content. Text injected by scripts after load is invisible to this check, so single-page apps will read lower than visitors experience.

Frequently Asked Questions

Is this code to text ratio checker free? Yes, completely free — no signup, no limits, no account.

Is my HTML uploaded anywhere? No. Checking happens entirely in your browser, so your source never leaves your device.

What is the code to text ratio? The visible text size divided by the total HTML size, shown as a percentage. A 25% ratio means a quarter of the page source is words a visitor can read; the rest is markup, scripts and styles.

What is a good ratio? Below 10% is commonly read as thin; 25–70% is commonly cited as healthy. These are rules of thumb from audit practice, not thresholds published by any search engine.

Does the ratio affect my Google ranking? Not directly. Google's John Mueller said in 2018 that code-to-text ratio is not a direct ranking factor. It is still useful as a signal for thin pages and heavy templates.

Can I check a live page by typing its URL? No. A browser page cannot fetch arbitrary websites, so this tool checks pasted HTML source only. Copy the page source and paste it here.

What counts as visible text? The text nodes left after removing comments, script blocks, style blocks and all tags. Alt text, titles and hidden text are not counted as visible text.

Why are scripts and styles excluded? Because visitors never read them. Counting code as text would hide exactly the bloat this check is meant to reveal.

Why does my JavaScript-heavy page score so low? Because content injected by scripts after load is invisible to a source check. The score reflects the raw source, not the rendered page a visitor sees.

Are sizes measured in characters or bytes? Bytes, measured as UTF-8, which matches how large the source really is on the wire.

Should I add filler text to raise my ratio? No. Filler hurts readers and adds nothing real. Reduce code weight or write content that genuinely helps, and the ratio follows.

Can I compare two pages with it? Yes — check each page's source separately and compare the ratios, but only between similar page types, such as two articles or two product pages.

Does it work on mobile? Yes. The tool runs in any modern mobile browser and the layout adjusts to small screens.

Final Thoughts

Code-to-text ratio is a useful mirror, not a target: it shows whether a page is mostly content or mostly scaffolding. Paste the source, read the breakdown, and fix the weight — not the number.
