How to filter by standard product sizes in woocommerce?

Question

WordPress

All good day.
Can you please tell me whether it is necessary to set attributes separately in order to make a filter by size?

In the goods I prescribe the dimensions, as I understand it in delivery.
The dimensions are also specified in variations

Separately, there are attributes by material

Here, by materials, the filter is done without problems, to filter by size, it turns out that it is also necessary to make attributes by size ??

Answer 1

Sizes are supposed to be for delivery, not for filtering, so yes - you need to make an attribute with sizes separately for filtering.
