How long should a product description actually be?
There is no magic word count — not 50 words, not 300. Sellers usually land in one of two wrong places: a single rushed sentence, or a wall of text nobody finishes reading. The right length is the one that answers every real doubt a buyer has and stops the moment it runs out of doubts to answer.
Forget word count. Count the doubts instead.
Before writing a single line, work out which of these actually apply to this product. Each one that applies earns a sentence or two. Each one that does not, skip — that is what keeps a description from turning into padding.
Price point
A $9 sticker needs almost no justification. A $180 leather bag needs enough detail that the price stops feeling like a question mark.
Uniqueness
If a buyer can find ten near-identical items on the same search page, the description has to earn the click by explaining what is actually different here.
Fit or sizing
Clothing, jewellery, and anything worn on the body needs real measurements and a sizing note. For apparel specifically, that means fabric weight (GSM), how the fit runs (true-to-size vs. oversized), and a model's height with the size they're wearing — skipping this is the single biggest cause of returns.
Materials or ingredients
Skincare, supplements, food, and anything that touches skin or gets eaten needs an honest ingredients or materials line, even if short — buyers actively look for it.
Care or use instructions
If getting it wrong ruins the product (hand-wash only, keep away from heat, patch-test first), that line belongs in the description, not buried in a policy page.
Three real products, three right lengths
A $12 soy candle
Short — 2 to 3 sentences
Hand-poured soy wax candle, 40-hour burn time, lavender and cedar scent. Comes in a reusable amber glass jar. Ships in 1–2 days.
Why this length: Low price, low risk, one real doubt worth answering (burn time). Padding this out with a life story about the candle-maker's journey does not sell more candles — it just delays the "add to cart" click.
A $180 leather crossbody bag
Medium — 4 to 6 sentences
Full-grain leather crossbody bag, hand-cut and stitched, with an adjustable strap (drops 18–24"). Fits a phone, cardholder, and keys with room for sunglasses. The leather is left undyed on the edges so it develops its own patina over the first few months of use — that is a feature of full-grain leather, not a flaw. Comes with a small care card for conditioning.
Why this length: At this price, a buyer has real doubts: what fits inside, how it ages, whether the strap works for their build. Each sentence answers one specific doubt instead of repeating "handmade" and "quality" as adjectives.
A $34 facial serum
Medium-long — a short paragraph plus a clearly separated ingredients line
A lightweight vitamin C serum formulated for dull, uneven skin tone — apply a few drops after cleansing, before moisturizer. Non-greasy, fragrance-free, safe for daily use. Key ingredients: 15% L-ascorbic acid, ferulic acid, hyaluronic acid. Patch-test recommended before first full use.
Why this length: Skincare buyers are actively scanning for two things — what it does and what is in it. Separating the ingredients line from the sales copy makes both easy to find without turning the whole description into a label.
A quick way to check your own listing
If it's under 3 sentences and the item costs more than $50 or is worn/used on the body, it's probably too short — a buyer is being asked to trust a price without enough reason to.
If you can delete a whole sentence and nothing important is lost, it's too long — that sentence was written to fill space, not to answer a doubt.
If it genuinely needs to be long, structure it so no one has to read all of it
Some products — a detailed book, a technical tool, anything with real depth — earn a longer description fairly. The mistake isn't the length, it's presenting all of it as one unbroken block and hoping the buyer reads to the end. Put 3 to 4 bullet highlights (the specific facts a skimmer needs: what it is, what's included, the one differentiator) right after the opening line, then let the full narrative follow underneath for the buyer who wants it. That way a 10-second skim and a 2-minute read both come away satisfied.
