Headings & Paragraphs
Learn the different heading sizes and how paragraphs work.
Step 1 of 4
Six sizes of headings
HTML has six heading levels: h1 (biggest) through h6 (smallest). They exist to create a clear content hierarchy — just like a Wikipedia article has a title, section headings, and sub-sections. Search engines like Google use your headings to understand what your page is about, which directly affects how it appears in search results.
Think of it this way: Open any Wikipedia article — the page title is an h1, section titles like 'Early life' or 'Career' are h2s, and sub-sections under those are h3s. This structure lets both readers and search engines quickly scan what the page covers.
Web Standard
Headings create a document outline. Screen readers let users jump between heading levels to navigate — skipping levels (h1 to h3) breaks this accessibility feature. Always use headings in order.
