How to use dimensions or attributes in products

We now want to implement the Dimension of the product, but through investigation, we found that there are only 4 existing Dimension and 11 unexpanded fields, and there are only 15 Dimension in total, and the values of these dimensions are immutable, but due to the complexity of our product Sex, 15 Dimension is far from enough to use, do you have any good suggestions?

Which dimennsions are you talking about? Inventory dimensions? If so, it’s more than 15 of them, but there indeed is a limit. If you need an extreme number of inventory dimensions, you’ll need a lot of extra development. If I was you, I would first review if the solution is designed correctly.

You mentioned attributes. Ask yourself if you can’t use them instead of some dimensions.
