Quick Takeaways
The Amazon product description character limit is 2,000 characters, and the field is plain text now. Amazon stopped supporting HTML tags in descriptions after July 17, 2021. The bold and bullet-list advice still floating around online will silently strip your formatting, because only the line break survives.
The Amazon product description character limit is 2,000 characters, and the bigger problem is what you're allowed to put in them. Most guides on this topic are five years out of date.
They'll tell you to bold your benefits and break your text into lists with HTML. That advice worked once. It stopped working in 2021.
Amazon announced the change to sellers directly. It said that after July 17, 2021, it would stop supporting the use of HTML tags in the product description on product detail pages.
Use those tags today and nothing errors. Your formatting just quietly stops rendering.

Conclusion
What the Amazon Product Description Character Limit Covers
Two thousand characters is roughly 300 to 350 words. That's the block of text below your bullets, headed "Product Description" on the detail page.
It's the last field most sellers write and the first one they skip. Both instincts cost more than they look like they do.
The count includes spaces, punctuation, and line breaks. It's characters rather than bytes, which sets it apart from your backend search terms.
That distinction matters if you write in more than English. Backend keywords are measured in bytes, where an accented letter costs double, while this field counts characters the way you'd expect.
The HTML Advice That Died in 2021
Amazon's reasoning was practical. It cited security for customers and the need to display listings on non-HTML devices.
The rollout happened in stages, which is partly why the confusion persists. Amazon's European sellers were told the cutoff was June 8, 2021, while the announcement above gave July 17 for the US.
What happens now isn't a rejection. Amazon explained that a product description containing unsupported HTML tags would simply stop showing HTML formatting.
Read that carefully, because it's the trap. The line might be removed entirely, or shown stripped of its formatting, depending on the tag.
So an old listing full of bold tags isn't flagged. It's just quietly worse than you realise, and nothing told you.
What you type against what the customer actually sees.
Only One Tag Survives Today
One tag made it through. Amazon's own detail page guide instructs sellers not to include HTML, JavaScript, or other types of executables other than break in their detail pages.
Here's the honest state of the field:
Each element, whether it renders, and what Amazon does.
Line breaks are your entire formatting toolkit. Used well, they're enough to turn a wall of text into something scannable.
Be careful where you get your description from, though. Plenty of free "Amazon HTML description generators" still exist. Pasting their output into a live listing today wastes characters on tags that never render.
What Amazon Prohibits Outright
Formatting isn't the only rule here, and these ones carry weight. Amazon's detail page guide bans seller-specific information such as price points and delivery speeds.
Contact details are out too. Phone numbers, physical addresses, email addresses, and website URLs are all prohibited in titles, descriptions, and bullets.
The logic is consistent once you see it. Amazon owns the transaction, so anything routing a customer off the platform or promising terms Amazon doesn't control gets barred.
Review references break the same rule. Quoting your own five-star reviews inside the description isn't allowed, because Amazon displays reviews itself.
What Amazon bans, and what deserves the space instead.
Why the Description Still Earns Its 2,000 Characters
Sellers skip this field constantly. The title and bullets get the attention, and by the time those are done, the description feels like paperwork.
That's a mistake for two reasons. Amazon indexes the text, so it's a home for long-tail phrases too specific for your title.
The second reason sits outside Amazon entirely. Your detail page can rank in Google, and the description is the closest thing your listing has to a body of copy.
Use it for the questions bullets can't answer. Bullets state a benefit, while 2,000 characters have room for how the thing works, who it suits, and what's in the box.
Don't just repeat yourself, though. Copying your bullets into the description spends two fields saying one thing, and Amazon reads them separately.

Seller Central gives you the box without a live count, which is how 2,400-character drafts get discovered at save time. UltraWordCounter counts as you type, in your browser, with nothing uploaded and nothing saved.
The free Amazon product description word count checker tracks your draft against the 2,000-character ceiling and shows the word count alongside it. Paste, trim, then copy back.
Run a keyword density check on the same text while you're there. It shows which phrases repeat, and repetition here is duplication rather than emphasis.
Everything runs free up to 800 words per session, which covers a description with room to spare. Questions about how the counter treats line breaks and symbols are answered on the UltraWordCounter FAQ page.
Sellers rewriting a catalog will pass the session cap. The Pro plan removes the 800-word limit for $19 a month, or $12 if you pay annually ($144/year), with a 7-day free trial.
Every other field has its own ceiling, and they don't agree with each other. Our guide to every Amazon FBA listing character limit collects them in one place.

Frequently Asked Questions
What is the Amazon product description character limit?
It's 2,000 characters, including spaces and line breaks, which works out to roughly 300 to 350 words. The field is measured in characters rather than bytes, unlike your backend search terms. Brand Registry sellers using A+ Content replace this field entirely with modules that have their own limits.
Can I use HTML in my Amazon product description?
No. Amazon stopped supporting HTML tags in product descriptions after July 17, 2021, and its detail page guide permits no executables other than the line break. Bold, italics, and list tags get stripped rather than rejected, so your listing looks fine in Seller Central while rendering as plain text.
Does HTML still count toward my 2,000 characters?
Any tag you type occupies characters in the field, so you'd be spending your budget on markup that never renders. That's the worst of both outcomes. Since only the line break works, strip everything else out and spend those characters on words a customer will actually read.
Does Amazon index the product description for search?
Yes, the text is searchable, which makes the field useful for long-tail keywords that don't fit your title or bullets. It carries less weight than the title. Your detail page can also surface in Google, where the description is the main body of copy on the page.
What is A+ Content, and does it replace the description?
A+ Content is a Brand Registry feature that swaps the plain description for modules with images and formatted layouts. If you have it, it displays instead of your standard description. Sellers without Brand Registry keep the 2,000-character plain text field, so the limits in this guide still apply.
Conclusion
The Amazon product description character limit is 2,000 characters of plain text, and that second half is what trips people. HTML died in this field after July 17, 2021, and the guides still recommending it are describing a version of Amazon that no longer exists. Line breaks are all you get.
Check before you save. Paste your draft into UltraWordCounter, confirm it fits 2,000, then strip every tag except the line break.
Spend what's left on the answers your bullets had no room for. Try it free and stop shipping formatting that never renders.
