Updated dimension attributes for 255 product types

Effective April 26, 2022, our new required dimension attributes give customers more precise data to help them find and compare products. For example, customers can distinguish between length and depth to filter search results more accurately.

Update your product dimension attributes

After a 30-day grace period beginning on April 26, 2022, you’re required to enter the new dimension attributes when you create and update ASINs through Manage Inventory and bulk inventory templates.

We urge you to update your product dimensions before the grace period ends and the old attributes are removed. We’ll move existing item dimensions to the new attributes if they’re accurate. You’re required to add values that are missing or may not have been updated due to formatting issues or differing value parameters.

You’ll be prompted to add missing dimensions when you edit your catalogue, such as when you update price or product information. Look for our ongoing reminders to provide any missing values.

New item dimension attributes for 255 product types

The new attribute definitions are clear and specific to product types. For example, WALL_ART has two attributes: length (longer edge) and width (shorter edge). For TENT, the width definition specifies the following: “Provide the longer edge at the bottom of the tent when assembled.”

We’ve also reduced the acceptable values for units of measurement. In the US, dimensions are given in inches only. In all other stores, dimensions are given in centimetres (with a few exceptions). Values must be numeric and greater than zero.

Unit of measurement: US (inches), all other stores (centimetres)
