@Nancy7 you can set the size of your tile (in inches) in the Design Tool - go to effects and choose which tiling effect you want (half brick/half drop or whatever) then in the Tile Size Box - you can enter width/height to your exact sizing preferences.
edit to add -
for the tablecloth - there is a size overlaid (which is really helpful) so perhaps they’ll roll this out to all the products.
edit again
the size of the product is on the bibs too (excellent news)
