A wall of text kills conversions. When your product description runs ten paragraphs deep, most shoppers never reach the Add to Cart button — they bounce. Limiting the visible text (with an elegant expand option) keeps pages scannable while preserving every word for SEO. The best part: it takes a few lines of CSS or Liquid, with no app and no monthly fee. Below are 5 ready-made variations — from a simple 3-line ellipsis to a smooth read-more toggle. Pick your style, paste it into a Custom Liquid section, and tighten up your product pages today.

1. Fashion Store – 3-Line Ellipsis

The fastest fix in the list — pure CSS clamps any description to three tidy lines with an ellipsis. Perfect for apparel stores with supplier-written novels.

How to Add Product Description Text Limit to Shopify

No app needed — this works with a free built-in Shopify feature called the Custom Liquid section. It takes about two minutes:

1. From your Shopify admin, go to Online Store → Themes.
2. Click Customize next to your live theme (works with Dawn and all Online Store 2.0 themes).
3. In the theme editor, use the top dropdown to navigate to a product page.
4. In the left sidebar, click Add section → Custom liquid.
5. Delete the placeholder code, paste the code from your chosen variation above, and click Save.
6. Preview your store — the change is live instantly. Drag the section up or down to reposition it.

Tip: Always duplicate your theme first (Themes → … → Duplicate) so you have a backup before editing.

Customize the Product Description Text Limit

• Line count: change -webkit-line-clamp: 3 to any number of visible lines.
• Word limit: in the Liquid version, adjust truncatewords: 40 up or down.
• Button text: rename ‘Read more’ to match your brand voice (‘View details’, ‘See more’).
• Animation: tweak the transition speed in the toggle version for a snappier or softer expand.
