Shipping weight helper
Three quick calculators for getting product weights into Shopify correctly, and a table of rough ranges for spotting weights that are obviously wrong.
Unit converter
Packed weight
Item weight times quantity, plus the box or mailer, plus filler. If you use carrier-calculated rates, Shopify adds the package weight from your shipping settings on its own. In that case, enter just the item weight on the product.
Dimensional weight
Carriers bill large, light boxes by size: length × width × height ÷ a divisor. Common divisors are 139 and 166 (inches and pounds) and 5000 (centimetres and kilograms), but each carrier and contract sets its own, so check your rate guide.
Rough weight ranges for a sanity check
These are broad ranges for unpacked items. They're only meant for catching mistakes such as a hoodie at 0 g, or a T-shirt at 200 lb because someone typed grams into a pound field. They are not a replacement for weighing. Put one of each product on a kitchen or shipping scale, then copy that weight to every variant of the same size.
| Product type | Typical range | Roughly |
|---|---|---|
| T-shirt (adult, cotton) | 120–250 g | 4–9 oz |
| Hoodie / sweatshirt | 400–900 g | 14–32 oz |
| Jeans | 450–900 g | 1–2 lb |
| Socks (pair) | 30–100 g | 1–3.5 oz |
| Sneakers (pair, in shoebox) | 0.9–1.8 kg | 2–4 lb |
| Paperback book | 150–500 g | 5–18 oz |
| Hardcover book | 400–1,200 g | 14–42 oz |
| Ceramic mug | 250–450 g | 9–16 oz |
| Candle in glass jar (about 8 oz of wax) | 350–550 g | 12–20 oz |
| Phone case | 20–80 g | 1–3 oz |
| Ring, earrings, pendant | 2–30 g | under 1 oz |
| Poster or print (rolled, with tube) | 150–400 g | 5–14 oz |
| Packaging: poly mailer / padded mailer | 10–60 g | 0.3–2 oz |
| Packaging: small corrugated box | 100–300 g | 3.5–10.5 oz |
These ranges are approximate. Materials, sizes and brands vary a lot, so use your own scale for the weights you enter.
Getting weights into Shopify
- One product at a time: on the product page, find the shipping section and turn on physical product, then enter the weight. Shopify's help notes the weight "needs to be exact because it's used to calculate shipping rates."
- Many products: export the products CSV, fill the
Weight value (grams)column (always in grams, whatever display unit you use), then import with overwrite existing products turned on. Step-by-step guide. - Find what's missing first: the product CSV checker lists every shippable variant with no weight.
