Character limits — why your blurb arrives shortened

Every A+ module has its own character limits, and they are small. The sidebar module's body text stops at 500 characters. A normal back-cover blurb is two or three times that.

Amazon does not warn you. It cuts whatever will not fit.

What we do about it

When the tool prefills a module from your book, it shortens the text to the last whole sentence that fits. So a 630-character blurb arrives as 405 characters ending on a full stop, rather than stopping mid-word. When that happens the field says so:

Shortened from your book to fit Amazon's 500 characters — edit it however you like.

Your full blurb is untouched on your cover. This only affects the copy that goes into this one Amazon field.

If you write your own and it runs over

The counter beside each field shows how many characters you have used out of the limit, and turns red past it. You get a Trim to fit button, which cuts at the last sentence that fits, and a warning explaining that Amazon truncates the rest.

Nothing stops you leaving it long — it is your text. But the README in your download will carry a line flagging that field as over the limit, so you find out before Amazon does rather than after.

Where the wording actually goes

We never bake wording into the images. Amazon rejects images with small text in them, and text pasted into Amazon's own fields is searchable and readable on a phone. The READ ME in your ZIP lists every headline, body paragraph and image description ready to paste into the matching KDP field.
