How do you add product dimensions in Shopify?

Where do you enter dimensions for shipping rates?

Packed product size is the product's outer size once packed.

1. In Products, open the product (opening one of its variants is optional).
2. In the Shipping section, make sure Physical product is on.
3. Under Packed product size, enter length, width and height and pick the unit. Enter all three or none: one or two aren't saved.
4. Click Save.

Enter an accurate weight there too.

With a packed size on every item, Shopify packs the shipment into your smallest saved box that fits, for carrier-calculated rates; only Box-type packages count, and a variant's assigned package takes priority on a single-item order. Yet Shopify's label requirements page says checkout uses only the default package's dimensions, so test checkout.

If an item lacks a packed size, no box fits, your default isn't a box, or you have many saved boxes or order items, your Store default package is used.

How do you show dimensions on the product page?

Use a metafield: for a furniture store, Shopify suggests a product metafield called Dimensions. No Help Center page we read on November 5, 2026 (packaging, product, CSV, metafield and theme pages) describes a built-in dimensions field for shoppers.

1. In the product's Product metafields section, click Add definition and name it.
2. Click Select type, choose Dimension (metric or imperial) and save. A Dimension value holds one number and unit, so add a definition per measurement.
3. Enter each product's value in its Product metafields section.
4. In a theme that supports metafields, connect each metafield to a section or block setting in the theme editor; not all sections or blocks support dynamic sources.

Can you add dimensions to many products at once?

Yes: for packed size, Shopify's packaging guide names the bulk editor and product CSV import. In the CSV, fill in all four packed product columns or leave all four blank (length, width, height, dimension unit), or the product won't import. On rows with variant data, four blank cells clear saved sizes when overwriting; to keep them, omit the columns.

Product metafields are supported in CSV, variant metafields aren't, so import a Dimension metafield at product level.
