HTML Lang Attribute Checker
Ensure your website is accessible, SEO-friendly, and WCAG-compliant with our free online HTML lang attribute checker. Quickly analyze any page to verify whether the lang attribute is set correctly.
What is the HTML Lang Attribute?
The HTML lang attribute tells browsers, search engines, and assistive technologies which language the page is written in. For example:
<html lang="en">
Without it, screen readers may mispronounce text, search engines may misinterpret content, and your site can fail accessibility checks.
Why is the Lang Attribute Important?
- Accessibility (WCAG 3.1.1) – Screen readers rely on the lang attribute for accurate pronunciation.
- SEO Benefits – Search engines understand the context and serve your content to the right audience.
- User Experience – Helps browsers apply proper spelling and grammar tools for the chosen language.
Adding a correct lang attribute improves usability, compliance, and visibility online.

Frequently Asked Questions
What does the HTML lang attribute check tool do?
This tool fetches a single web page and analyzes its HTML document to verify the presence and validity of the lang attribute on the element. It reports errors, warnings, and suggestions related to missing or malformed language declarations.
Why is the lang attribute important?
The lang attribute helps browsers, assistive technologies (like screen readers), and search engines understand which language the page is written in. It’s a key accessibility requirement (WCAG 3.1.1) to ensure correct pronunciation and interpretation of content.
What counts as a “valid” lang attribute?
A valid lang value follows the BCP 47 standard (for example, en, en-US, fr, es-ES). The tool will flag unusual formats or empty values. It also checks if multiple tags exist or if the document lacks a DOCTYPE.
Can I check multiple pages or a whole website?
No — this version is limited to analyzing one page at a time via its URL. If you’d like a bulk or site-wide version (e.g. for auditing many pages), we can build that separately.
