How Long Should a Product Description Be?

The honest answer: as long as it needs to be, and no longer. But "it depends" isn't useful, so here are working ranges and the logic behind them.

Practical ranges

• Simple, low-cost, familiar products (a phone case, a basic tee): 50–100 words. Shoppers already understand the product; don't pad it.
• Mid-range products (most of a typical catalog): 100–200 words. Enough room for a hook, key benefits, and the specs that matter.
• Considered or premium purchases (furniture, electronics, jewelry): 200–400+ words. Higher price means more questions to answer before someone buys.

What actually drives length

Word count is an output, not a goal. Length should follow:

1. Price and risk. The more someone is spending, the more reassurance and detail they need.
2. Complexity. Technical products need specs, sizing, materials, compatibility.
3. Search intent. Some products are bought on impulse; others after research. Match the depth to how people shop for that item.

Length and SEO

Longer is not automatically better for ranking. What matters is that the description is unique, useful, and answers real questions — not that it hits a word count. A thin, duplicated 60-word description ranks worse than a focused 120-word one written for the shopper. Don't write filler to look "long."

Keeping length consistent at scale

The hard part isn't deciding the length for one product — it's applying a sensible length policy across thousands. With the AI Product Description Generator you can set custom instructions like "keep descriptions around 120 words, benefit-led, skimmable" and apply them across your whole catalog, so length stays consistent without manual editing.

Rule of thumb

Write the shortest description that fully answers the shopper's questions and includes the words they search. Then stop.
