How can I add product dimensions to each item on my kids fashion store?

we are owners of a kids fashion online store, and we need to add the product dimensions on every size in every product, as we did it on our old website but it was native, now we are on shopify, screen shot attached

we expected to upload the dimensions of every size with the product sku, in the product upload sheet
